Definitions

  • the present invention relates to the field of child protection. DESCRIPTION OF THE PRIOR ART
  • the present invention relates to a child seat alarm and more particularly pertains to preventing a child from being inadvertently left inside a motor vehicle.
  • a device for alerting a user to the presence of a child in a vehicle comprising a housing having a first sensor for sensing the presence of at least one of a child and infant positioned therein.
  • a means for detecting the operative mode of a vehicle engine is connected to the first sensor.
  • a means for indicating the presence to a third party is connected to the first sensor. The indicating means is activated and indicates to the third party the presence of said at least one child and infant upon the detecting means detecting that the vehicle engine is in a first off mode and the first sensor sensing the presence of the at least one child and infant.
  • This system relies on significant alterations to the interior, exterior and engine of the vehicle and is also designed as an integral part of a purpose-built child seat. As a result it depends on vehicle manufacturers to design specific sensors, processors and connections into their vehicles to support the use of the child seat or for end users to modify their vehicles significantly for the same purpose. It also requires the end user to retain the same child safety seat for the duration of the eight years a child typically uses a child seat rather than using multiple seats as the child grows and/or moves between different vehicles within the same family as is more typically the case. Additionally, this invention relies on a complex processor and weight sensor to make complex calculations prior to sounding the alert which leaves significant room for error, and resulting misfires or failures in addition to adding prohibitively expensive components to the system.
  • this invention lacks a test mode that would provide the end user with evidence that the system is functioning prior to the need for an alert, at which point it may be too late. It may also rely on a receiver and transmitter to relay information from the vehicle to the seat or a transportable remote, a transmission that could fail due to environmental interference. The system may also delay the alert signal upon activation to give the end user an opportunity to remove the child, but in that delay may allow the end user to sufficiently leave the vicinity of the vehicle.
  • a child seat alarm including a car seat portion adapted for being positioned within a motor vehicle.
  • the car seat portion includes child engagement straps.
  • the child engagement straps include a male buckle and a corresponding female receptacle.
  • the male buckle is lockably received within the female receptacle in a locked orientation.
  • An alarm is disposed within the car seat portion.
  • the alarm includes a pair of speakers for broadcasting an audible alarm.
  • the alarm is in an activated orientation when the male buckle is lockably received within the female receptacle.
  • the alarm is in a deactivated orientation when the male buckle is removed from the female receptacle.
  • the alarm is in communication with an electrical system of the vehicle whereby a shut down of the motor vehicle's engine or an opening of a driver's door will sound the alarm when the alarm is in the activated orientation.
  • This invention relies on a sensor built into the seat belt buckle of a car seat to indicate occupancy within the car seat which requires that the alert system be designed into the car seat itself which again presents financial difficulty for end users with multiple cars and child safety seats or a need to upgrade or replace the seat as the child grows.
  • This system also relies primarily on an audible alarm which presents an opportunity for failure in areas of significant background noise or with end users with hearing difficulties.
  • a display is provided for mounting to the top of the vehicle dashboard but the function and purpose of the display is unclear and typically traffic laws do not allow for items to be placed on top of a vehicle dashboard for safety reasons.
  • This invention also relies on a switch integrated into the ignition or door system of the vehicle either by the vehicle manufacturer or by the end user.
  • This system fails to provide a test mode that indicates operational status. Furthermore, this invention has no means of delivering the alert signal to the exterior of the vehicle and is thereby unable to alert the driver of the vehicle if able to exit the vehicle.
  • Warning system for detecting presence of a child in an infant seat
  • An apparatus for warning when a child has been left in an infant seat and a vehicle has been turned off.
  • the apparatus includes an occupant detection mechanism for detecting the presence of an occupant within an infant seat located within a vehicle; an ignition detection mechanism for detecting the state of the vehicle's ignition system; a control unit for generating an alarm signal when the occupant detection mechanism detects the presence of an occupant within the infant seat and the ignition detection mechanism detects that the vehicle's ignition system has been turned from an "on" state to an "off state; and an alarm units for generating an alarm in response to the alarm signal.
  • the components of the apparatus can be located within the infant seat, within the vehicle or combined within the infant seat and the vehicle.
  • This invention is designed as an integrated part of a car seat, and/or requires a direct connection to the ignition and other modifications to the vehicle requiring complex and therefore unlikely coordination between the manufactures of the vehicle and child seat and as such presents the same problems as the above prior art.
  • This invention also relies on a complex system for data assessment prior to initiating the alert and as such provides significant room for error, misfire or failure.
  • This invention also relies on the components of the vehicle (horn, lights, etc.) to provide external alerts in the event the driver does depart the vehicle.
  • This invention also requires operational power to be provided by the vehicle battery after the ignition has been terminated which is known to be damaging to the vehicle battery in addition to being an undesired vehicle modification.
  • This invention also relies on a heat sensor to detect the heat level within the car before activating other complex vehicle systems.
  • a system and method uses a wireless tether comprising a transmitter and a receiver to alert a caregiver that an object or person has been left unattended.
  • a detector senses the presence of the object, usually a child, located in a position such as a safety seat. The detector couples to the transmitter, which is located near the object. The transmitter transmits at least one wireless signal when the object is in the position.
  • the receiver which is remotely located from the transmitter, senses the at least one signal as long as the receiver is within a prescribed range of transmission. By performing a timing function, the receiver monitors the proximity of the caregiver, who maintains possession of the receiver, to the transmitter. The system communicates an alarm to the caregiver when the caregiver ventures outside the range of transmission without having removed the object/child from the position.
  • This invention utilizes a transmitter positioned on or near the child and another on the driver of the vehicle and once the two have separated from each other by a prescribed distance, an alert is initiated.
  • the transmission system can be interfered with by environmental conditions, or the batteries can become unknowingly depleted causing failure to alert. Additionally these systems require the caregiver to leave the vehicle and walk away a certain distance before the potential for any alarm.
  • US 7209033 B2
  • the device has a transceiver which transmits high-frequency signals, which are reflected back by reflectors in the seats. Occupied seats are detected on the basis of signal propagation delays and/or reflector detections and/or receiving intensities. In addition, it is possible to detect with the aid of a belt sensor whether or not a safety belt is fastened.
  • This invention utilizes a complex system of high frequency transmitters and data assessment mechanisms to determine precise vehicle occupancy for use by vehicle systems. This invention does not provide an alert system in conjunction with the occupancy detection.
  • a child safety seat comprises a safety seat unit.
  • An alarm unit is coupled to the safety seat unit.
  • the alarm unit sounds an alarm to remind occupants of the vehicle when a child is sitting in the child safety seat after the ignition of the vehicle in which the child safety seat is installed is turned off.
  • This invention is designed as an integrated part of a car seat, and/or requires a direct connection to the ignition, electrical system and other modifications to the vehicle and as such presents the same problems as the above prior art.
  • This invention also relies on a complex system of fuses, diodes, and direct dial feeds from the vehicle systems and grounding within the unit and vehicle to operate. This invention does not have a means for sounding an alert outside of the vehicle.
  • Reminder device for eliciting behavioral response in a vehicle
  • a reminder device for alerting or triggering the memory of a vehicular occupant includes one or more visual, auditory and tactile indicators which the occupant associates with the presence of a person, pet, plant or inanimate object located in the vehicle.
  • This invention utilizes visual cues initiated and/or moved within the vehicle as a reminder system for eliciting a response from the caregiver.
  • Systems such as this are prone to forgetfulness on the part of the driver over time and as such may not be initiated by the driver on a regular basis.
  • An exemplary device can be provided for monitoring a child seat in a vehicle.
  • the exemplary device can include seat electronics attachable to the child seat, and a transmitter configured to transfer first signals from the seat electronics to vehicle electronics and configured to transfer energy and second signals from the vehicle to the seat electronics. Additionally, the transmitter can be attachable to an anchor point configured to fasten the child seat to the vehicle.
  • This invention relies on alterations to the vehicle and elements built in to the car seat to monitor various aspects of a child within the car seat unit.
  • the unit relies on complex mechanisms and electronics.
  • the system does not provide an alert mechanism for a child left unattended in the child seat.
  • a sensor is connected to the seat belt of the baby's car seat or to the rear seat belts. Once the seat belt is inserted into the belt buckle, an alarm circuit is activated. When the driver enters the vehicle and sits down the system detects the presence of the driver and deactivates the alarm circuit. When the driver exits, the alarm circuit is re-activated.
  • the system includes a delay timer that gives the driver time to enter and exit the vehicle without setting off the alarm circuit
  • This invention is designed as an integrated part of a car seat with a sensor built into the buckle of the car seat or the vehicle, a sensor device in the car seat or the vehicle to detect the presence of the driver in the vehicle and a built-in sensor device at the gas gap and trunk of the vehicle to determine the reason for the driver's absence and as such presents the similar vehicle and seat modification issues as the above prior art.
  • This invention also provides numerous opportunities to disable the system entirely or delay the initiation of the alert system thereby allowing the possibility that the driver will leave the area of the vehicle before the alarm is sounded.
  • a seat belt alarm system activates an alarm when a child is buckled in a car seat and when the car key is removed from the ignition.
  • the seat belt alarm system includes a belt buckle having a belt-buckled sensor and a transmitter that transmits a belt-buckled signal when the belt is buckled.
  • a remote key module includes a key-removed sensor that senses when the key is not in a keyhole.

  • the controller instructs the transmitter to send an activate-alarm signal to a receiver in the key module when a belt-buckled signal and a key-removed signal are input to the controller.
  • the alarm device may provide a sound, vibration, light, or another indicator.
  • Another variation includes a removable baby seat with a seat belt alarm system.
  • Still another variation includes an automobile having a seat belt alarm system.
  • This invention relies on modifications to the vehicle, the child seat, and also the ignition key itself to function as intended, in addition to transmission of wireless signals between a fob style key and a transmitter/receiver and as such is deficient in a similar fashion to the art described above.
  • a method includes determining whether a fastener of a child seat is fastened, determining whether a person is seated in a vehicle seat, and if it is determined that the fastener is fastened and the person is not seated in the vehicle seat: enabling a first notification signal of the alarm system, enabling a delay of the alarm system for a period of time, enabling a second notification signal of the alarm system if a door of the vehicle is locked within the period of time, and enabling the second notification signal after expiration of the period of time. If it is determined that the fastener is not fastened or the person is seated in the vehicle seat, the method includes resetting the alarm system.
  • This invention relies on significant modifications to the vehicle, the child seat, and coordination between manufacturers of those modifications to function as intended, in addition to a heat sensor and as such is deficient in a similar fashion to the art described above.
  • the present invention is able to address the deficiencies in the prior art by foregoing the complex sensors, processors and mechanisms required to detect the operational state of the vehicle as per the prior art, in favor of a simplified mechanism that instead reacts to a common state in modern vehicles that is adequately indicative of the operational state for the purposes of the alert.
  • That common state being a feature recently added to most modern cars wherein the vehicle will disable all USB ports and power outlets when the ignition switch is turned off to prevent a recently common problem of drivers using power outlets after shutdown to power mobile devices and other accessories which subsequently damages the vehicle battery. While this feature does not exist in older cars, adapting an electrical circuit that does holidays with the vehicle, such as a stereo circuit, to provide the necessary electrical connection is an inexpensive and non- complex modification, not evident in the prior art.

Description

CHILD PROTECTION SYSTEM AND APPARATUS
This application claims the benefit of US Provisional Application No. 61928585, filed 17-JAN- 2014.
FIELD OF THE INVENTION
The present invention relates to the field of child protection. DESCRIPTION OF THE PRIOR ART
The present invention relates to a child seat alarm and more particularly pertains to preventing a child from being inadvertently left inside a motor vehicle.
The use of alerting mechanisms for the means of preventing children from being left in motor vehicles is known in the prior art. Such prior art teachings, though they fulfill some of the needs for child safety, have certain functional deficiencies and/or are financially prohibitive.
In recent years a number of inventions encompassed by the crowded prior art have appeared in an attempt to reduce the number of children and infants killed or seriously injured as a result of being accidentally left behind in a vehicle. These inventions have utilized complex methodologies to achieve their intent, often relying on significant and prohibitively expensive alterations to the vehicle and/or the child safety seat either at the manufacturing or after-market levels. Alternatively some depend on unreliable transmission methods, or yet further allow the driver to leave the vehicle before activating the alert mechanism.
The following outlines the most relevant of those prior inventions and demonstrates how they insufficiently provide a solution that the present invention seeks to adequately address.

Child carseat alert system
ABSTRACT
A device for alerting a user to the presence of a child in a vehicle comprising a housing having a first sensor for sensing the presence of at least one of a child and infant positioned therein. A means for detecting the operative mode of a vehicle engine is connected to the first sensor. A means for indicating the presence to a third party is connected to the first sensor. The indicating means is activated and indicates to the third party the presence of said at least one child and infant upon the detecting means detecting that the vehicle engine is in a first off mode and the first sensor sensing the presence of the at least one child and infant.
DEFICIENCIES
This system relies on significant alterations to the interior, exterior and engine of the vehicle and is also designed as an integral part of a purpose-built child seat. As a result it depends on vehicle manufacturers to design specific sensors, processors and connections into their vehicles to support the use of the child seat or for end users to modify their vehicles significantly for the same purpose. It also requires the end user to retain the same child safety seat for the duration of the eight years a child typically uses a child seat rather than using multiple seats as the child grows and/or moves between different vehicles within the same family as is more typically the case. Additionally, this invention relies on a complex processor and weight sensor to make complex calculations prior to sounding the alert which leaves significant room for error, and resulting misfires or failures in addition to adding prohibitively expensive components to the system. Furthermore, this invention lacks a test mode that would provide the end user with evidence that the system is functioning prior to the need for an alert, at which point it may be too late. It may also rely on a receiver and transmitter to relay information from the vehicle to the seat or a transportable remote, a transmission that could fail due to environmental interference. The system may also delay the alert signal upon activation to give the end user an opportunity to remove the child, but in that delay may allow the end user to sufficiently leave the vicinity of the vehicle.

Child seat alarm
ABSTRACT
A child seat alarm including a car seat portion adapted for being positioned within a motor vehicle. The car seat portion includes child engagement straps. The child engagement straps include a male buckle and a corresponding female receptacle. The male buckle is lockably received within the female receptacle in a locked orientation. An alarm is disposed within the car seat portion. The alarm includes a pair of speakers for broadcasting an audible alarm. The alarm is in an activated orientation when the male buckle is lockably received within the female receptacle. The alarm is in a deactivated orientation when the male buckle is removed from the female receptacle. The alarm is in communication with an electrical system of the vehicle whereby a shut down of the motor vehicle's engine or an opening of a driver's door will sound the alarm when the alarm is in the activated orientation. DEFICIENCIES
This invention relies on a sensor built into the seat belt buckle of a car seat to indicate occupancy within the car seat which requires that the alert system be designed into the car seat itself which again presents financial difficulty for end users with multiple cars and child safety seats or a need to upgrade or replace the seat as the child grows. This system also relies primarily on an audible alarm which presents an opportunity for failure in areas of significant background noise or with end users with hearing difficulties. A display is provided for mounting to the top of the vehicle dashboard but the function and purpose of the display is unclear and typically traffic laws do not allow for items to be placed on top of a vehicle dashboard for safety reasons. This invention also relies on a switch integrated into the ignition or door system of the vehicle either by the vehicle manufacturer or by the end user. Modification of the vehicle by the end user is an undesirable requirement for financial reasons and subsequent vehicle value depreciation. This system fails to provide a test mode that indicates operational status. Furthermore, this invention has no means of delivering the alert signal to the exterior of the vehicle and is thereby unable to alert the driver of the vehicle if able to exit the vehicle.

Warning system for detecting presence of a child in an infant seat
ABSTRACT
An apparatus is provided for warning when a child has been left in an infant seat and a vehicle has been turned off. The apparatus includes an occupant detection mechanism for detecting the presence of an occupant within an infant seat located within a vehicle; an ignition detection mechanism for detecting the state of the vehicle's ignition system; a control unit for generating an alarm signal when the occupant detection mechanism detects the presence of an occupant within the infant seat and the ignition detection mechanism detects that the vehicle's ignition system has been turned from an "on" state to an "off state; and an alarm units for generating an alarm in response to the alarm signal. The components of the apparatus can be located within the infant seat, within the vehicle or combined within the infant seat and the vehicle.
DEFICIENCIES
This invention is designed as an integrated part of a car seat, and/or requires a direct connection to the ignition and other modifications to the vehicle requiring complex and therefore unlikely coordination between the manufactures of the vehicle and child seat and as such presents the same problems as the above prior art. This invention also relies on a complex system for data assessment prior to initiating the alert and as such provides significant room for error, misfire or failure. This invention also relies on the components of the vehicle (horn, lights, etc.) to provide external alerts in the event the driver does depart the vehicle. This invention also requires operational power to be provided by the vehicle battery after the ignition has been terminated which is known to be damaging to the vehicle battery in addition to being an undesired vehicle modification. This invention also relies on a heat sensor to detect the heat level within the car before activating other complex vehicle systems.

Self-activating system and method for alerting when an object or a person is left unattended
ABSTRACT
A system and method uses a wireless tether comprising a transmitter and a receiver to alert a caregiver that an object or person has been left unattended. A detector senses the presence of the object, usually a child, located in a position such as a safety seat. The detector couples to the transmitter, which is located near the object. The transmitter transmits at least one wireless signal when the object is in the position. The receiver, which is remotely located from the transmitter, senses the at least one signal as long as the receiver is within a prescribed range of transmission. By performing a timing function, the receiver monitors the proximity of the caregiver, who maintains possession of the receiver, to the transmitter. The system communicates an alarm to the caregiver when the caregiver ventures outside the range of transmission without having removed the object/child from the position.
DEFICIENCIES
This invention, and numerous others like it such as US 8038213 B2, utilizes a transmitter positioned on or near the child and another on the driver of the vehicle and once the two have separated from each other by a prescribed distance, an alert is initiated. As has been demonstrated by recognized consumer reporting firms, the transmission system can be interfered with by environmental conditions, or the batteries can become unknowingly depleted causing failure to alert. Additionally these systems require the caregiver to leave the vehicle and walk away a certain distance before the potential for any alarm. US 7209033 B2
Device and method for detecting an object or a person on a seat of vehicle
ABSTRACT
The device has a transceiver which transmits high-frequency signals, which are reflected back by reflectors in the seats. Occupied seats are detected on the basis of signal propagation delays and/or reflector detections and/or receiving intensities. In addition, it is possible to detect with the aid of a belt sensor whether or not a safety belt is fastened.
DEFICIENCIES
This invention utilizes a complex system of high frequency transmitters and data assessment mechanisms to determine precise vehicle occupancy for use by vehicle systems. This invention does not provide an alert system in conjunction with the occupancy detection.

Method and system for preventing leaving a child in an unattended vehicle
ABSTRACT
A method is provided that includes determining whether a fastener of a child seat is fastened, determining whether a person is seated in a vehicle seat, and if it is determined that the fastener is fastened and the person is not seated in the vehicle seat: enabling a first notification signal of the alarm system, enabling a delay of the alarm system for a period of time, enabling a second notification signal of the alarm system if a door of the vehicle is locked within the period of time, and enabling the second notification signal after expiration of the period of time. If it is determined that the fastener is not fastened or the person is seated in the vehicle seat, the method includes resetting the alarm system.
DEFICIENCIES
This invention relies on significant modifications to the vehicle, the child seat, and coordination between manufacturers of those modifications to function as intended, in addition to a heat sensor and as such is deficient in a similar fashion to the art described above.
In the years since the abundance of prior art has appeared, very little if any evidence of their existence has shown up in the marketplace and more importantly, the statistics have shown in the number of infant deaths each year as a result of accidental abandonment within a vehicle. In fact, in some recent years, the death rate has even increased.
It has become clear that vehicle manufacturers are unwilling or unable to implement the solutions in the prior art that require complex and expensive sensors, processors and other mechanisms that would drive up the cost of vehicles. It has also become evident that vehicle and child safety seat manufacturers have been unable to coordinate on prior art solutions that require elements from both parties to properly function. It has further become clear that parents and caregivers are unlikely to invest in a system solely devoted to the problem in question due to an inability to envision themselves becoming distracted enough in transit that they forget the child is in the vehicle once they reach their destination.
Unfortunately, as recorded accounts have shown, this is almost invariably the case often with the most devoted and routine oriented parents.
Consequently a need has arisen for an alert system that can achieve the required state of alert:
• Immediately and without delay.
• Without complex and/or expensive alterations and additions to standard vehicle.
• Without necessity for integration into a child safety seat at the OEM level, which in turn increases the cost and replaceability of that seat. • Within a system that can be easily installed, removed and reinstalled into alternative vehicles and/or child safety seats as needed.
• While providing additional features unrelated to accidental abandonment to help motivate purchase and installation into a vehicle
• In an economical manner.
Therefore, in order to effectively address the problems evident the present invention provides a solution simple enough to:
• Be incorporated into a vehicle by a manufacturer at the OEM level as an inexpensive feature or add-on without the need for coordination with child seat manufactures or significant modification to the vehicle itself.
• Be incorporated into a child seat by the child seat manufacturer without relying on any modifications to the vehicle whatsoever.
• As per the exemplary embodiment, be provided within an entirely independent
system that can be used in conjunction with any child safety seat or vehicle without the need for modification to either.
As can be seen in the exemplary embodiment, the present invention is able to address the deficiencies in the prior art by foregoing the complex sensors, processors and mechanisms required to detect the operational state of the vehicle as per the prior art, in favor of a simplified mechanism that instead reacts to a common state in modern vehicles that is adequately indicative of the operational state for the purposes of the alert. That common state being a feature recently added to most modern cars wherein the vehicle will disable all USB ports and power outlets when the ignition switch is turned off to prevent a recently common problem of drivers using power outlets after shutdown to power mobile devices and other accessories which subsequently damages the vehicle battery. While this feature does not exist in older cars, adapting an electrical circuit that does festivities with the vehicle, such as a stereo circuit, to provide the necessary electrical connection is an inexpensive and non- complex modification, not evident in the prior art.
The present invention then further provides supplementary features, such as an in-transit lullaby button or a vehicle collision alert to emergency personnel, that utilize features already present in the system to help the invention to appeal to parents and caregivers on a more relatable level than that of the prior art.

The exemplary apparatus 20 is shown in FIG. 1 and will be seen to include a control unit 22, an external speaker 24, a sensor mechanism 26 and a USB plug 28.
The control unit 22 includes a housing 30, a speaker 32, lights 33, 34, 35, 35a, a plurality of suction cups 36, and solar panel 37 [for passive recharging of the internal battery 39]. Lights 34 may be seen from both interior and exterior of the vehicle. Additionally lights 34 may be a single light source or plurality of light sources, steady, flashing, or in motion by mechanical means and may project illumination and graphics within and without the vehicle. It is also understood the lights may be of different colors or color-changing. The purpose is to present both a vivid reminder on all surfaces of the interior of the vehicle of the fact that a child is in the vehicle as well as an entertaining or soothing display for the child.
The external speaker 24 is a vibration speaker having an adhesive end 38 and is coupled to the control unit by wiring. The disclosure of a vibration speaker of application number US 6487300 B1 is hereby incorporated by reference.
The sensor mechanism 26 is a pressure pad switch coupled to the control unit by wiring and adapted such that, when operatively disposed in a child safety seat, the sensor mechanism is responsive to the presence of a child in the child safety seat.
The USB plug 28 is coupled to the control unit 22 by wiring.
The rear of the control unit 22, showing light 35a, 35b, namely, a "BABY ON BOARD" illuminated sign, is shown in FIG. 2
The apparatus 20 is shown in FIG. 3 ready for use with a vehicle 40 and a child safety seat 42.
In such state of readiness:
• the adhesive pad of the vibration speaker is mounted to a window in the vehicle
• the USB plug is engaged in a USB receptacle 44 in the vehicle or power outlet via an adequate adapter 44a. The disclosure of a vibration speaker of application numbers US 7686657 B1 , US 4789361 A, US 6842356 B2 are hereby incorporated by reference.
• the pressure pad switch 28 is operatively disposed in the child safety seat 42.
• the suction cups 36 are secured to the window of the vehicle such that the speaker 32 and light 33, 34, 34a are directed inwardly and lights 33, 35, 35a are directed outwardly. In use, when a child is placed in the seat 42, an alarm state is triggered whenever the vehicle is not operational, as determined by the presence of incoming electrical power through the USB plug or power outlet of the apparatus [it being understood that in the vehicle in question, the USB receptacle and/or power outlets within the vehicle are active only when the vehicle is in an operational state]. The alarm state is associated with an audio alarm and a visible indicator. The intensity and scope of the audio alarm vary as a function of the period of time since the alarm state was assumed: initially, a lullaby or soothing melody is softly played through the control unit speaker 32 and vibration speaker 24; thereafter, a louder alarm is sounded via the control unit speaker 32 and the vibration speaker 24. The visible indicator is provided by illumination of the light 33, 34, on the interior of the vehicle and 33, 35, 35a the exterior of the vehicle. The alarm state is immediately vacated when the vehicle is rendered operational, by suitable manipulation of the ignition switch (and consequent energization of the USB receptacle and/or power outlets).
The exemplary embodiment of the apparatus does not require any modification to the existing vehicle, or the child safety seat, nor does it require a special or purpose-built child safety seat. The exemplary embodiment of the apparatus works with any vehicle or child safety seat and may be moved, reinstalled, or transferred easily between alternate vehicles or child safety seats.
The exemplary embodiment does not require complex processors or mechanisms to detect vehicle or occupant status.
The alarm state is also immediately vacated when the child is removed from the child safety seat. The foregoing has substantial advantage in that it reduces the likelihood that a child will be inadvertently left unattended in the vehicle, as the operator is given an immediate reminder if a child is in the seat and the vehicle is turned off without allowing the operator to leave the vehicle for any period of time. The soothing audio sequence serves to provide the user with obvious but gentle evidence that the system is functional and ready to alarm at each use. It also provides the driver with a gentle distraction for the child to assist in the process of fastening the child into the car seat. It also serves to create a mental queue for the driver over time associating the sound with the presence of their child. It also allows the system to activate immediately without irritating the child.
Whereas but a single embodiment is herein described and illustrated, it will be evident that many variations are possible.
For example, in vehicles lacking a USB port or power outlet [that is activated only when the vehicle is operational] but having a cigarette lighter of the type which is active only when the vehicle is operable, an adapter 44a of the type having one end adapted to engage a cigarette lighter style receptacle and another end adapted to receive the USB plug can be used to couple the control unit to the vehicle to achieve the same functionality. As well, the apparatus could be adapted to couple with the OBD-1 1 port, or could be hard-wired using any one of a plurality of vehicle circuits 49 that are selectively activated and deactivated in response to the operational status of the vehicle. As well the apparatus could be adapted to operate directly with the basic 12V power of the cigarette lighter, which typically varies slightly, dependent upon the operational state of the vehicle.
As well, whereas in the exemplary embodiment, a lullaby or soothing melody plays immediately when a child is placed in the seat and the vehicle is disabled, the lullaby could commence following a short delay.
Further, whereas the exemplary sensor mechanism is a pressure pad switch, the sensor mechanism could, for example, be an infrared sensor 47, seat belt sensor 48, button, life signs detector, or other. An infrared sensor, for example, could be helpful in the avoidance of false alarms, if a person were to leave the car with, for example, a parcel rested in the car seat.
As well, conventional loudspeakers could be substituted for the vibration speaker, or the vehicle sound system, vehicle theft system, or horn of the vehicle could be utilized, potentially through interface with the OBD-1 1 port.
As well, cabin lights, headlights, signal lights, dashboard lights or other onboard vehicle lights could be substituted for or combined with the visual indicators of the device, potentially through interface with the OBD-1 1 port.
Alternatively, the system could be adapted to send a signal by email, SMS, onboard communication system or the like, to a cellular phone or other party, in replacement for, or as a supplement to, the external audible alarm.
According to another aspect of the invention, the apparatus can be a stand-alone device for connection to the vehicle and insertion into any child safety seat as shown in FIG. 1 , or as part of the vehicle built in at an OEM level with sensor connection points at the child safety seat locations as shown in FIG. 6, or built in to a child safety seat with a method of connection to the vehicle as shown in FIG. 5.
The system can be provided with an override button 45 to initiate the initial alarm state to utilize the lullaby or soothing melody and/or visual indicators for the purposes of soothing the child in transit. Said override bears no negative impact (delaying, resetting, or deactivating) on the overall alarm feature of the system.
The system could alternatively or additionally be provided with a "reset" button that will allow the user to extend the duration of the initial alarm delay time, or delay the alarm mode entirely for a predetermined amount of time, i.e. to allow for loading of groceries, multiple children, etc.
The system could alternatively or additionally be provided with an override button to turn system off in the event the child safety seat is used to transport objects rather than a child. The override button could reset after a predetermined or user input length of time, or upon cycling the power to the unit or the ignition of the vehicle.
The system can be provided with an override button to extend the length of the initial alarm state or disable the mechanism for a predetermined or user inputted length of time.
The override buttons can be provided at the mechanism, or at the location of the driver, or on the key fob device where the mechanism is built into the vehicle at an OEM level.
Further, whereas the illustrated embodiment is adapted for aftermarket sale, the sensor mechanism could be incorporated as an OEM component in a child safety seat for use with the stand alone system where the sensor is detachable for use with third-party sensors, or for use in a system provided as an OEM component in a vehicle where universal ports are provided at possible child safety seat locations for connection of said aftermarket sensor mechanisms.
Further, whereas the illustrated embodiment is adapted for aftermarket sale, the full apparatus could be incorporated as an OEM component in a child safety seat system.
The apparatus can be a stand-alone device for connection to the vehicle and insertion into any child safety seat, or as part of the vehicle built in at an OEM level with sensor connection points at the child safety seat locations, or built in to a child safety seat with a method of connection to the vehicle.
