Description
METHOD AND APPARATUS FOR PROVIDING
ACCESS TO A SECURE REGION
BACKGROUND OF THE INVENTION
The invention relates in general to a home security system and in particular to a home security system which can be controlled remotely to allow entry to a dwelling.
While local entry only systems exist there are not many systems that will allow entry to a portion or all of the dwelling in response to a remote signal. One of the oldest types of systems which will allow such entry at least to a portion of the dwelling is a remote control garage door operator. Such operators typically respond to one or more radio frequency transmitters. The RF transmitters emit code-modulated signals. When the signals are received by a receiver in the operator they identify the transmitter as an authorized transmitter.
In response the receiver signals other parts of the operator to open or close a garage door. Upon obtaining access to the garage further access may be obtained to other portions of the dwelling.
Another non-keyed system for obtaining access to dwellings is the Weiser lock. The Weiser system has a keypad transmitter of the type used for operating a garage door operator. The keypad transmitter transmits a signal to a door lock of the type provided by the Weiser Company causing the lock to release or become unlocked.
The Weiser system can cycle a deadbolt from a locked to an unlocked position and then from the unlocked to the locked position. It operates at the approximate range of a garage door operator transmitter.
Still another system is disclosed in U.S.
Patent No. 5,872,513 to Fitzgibbon et al. Fitzgibbon et al. teach a system that has a garage door operator having a temporary password programming feature.
While these non-keyed systems are convenient to use they nevertheless fail to address several important considerations. One of which is that a person may wish to allow access to the dwelling while the dwelling is unoccupied at particular times of the day but not be present to grant such permission. No such system is presently available other than to leave the door of the dwelling unlocked or to request a neighbor to provide access to package delivery personnel, home maintenance personnel, tradesmen and the like.
What is needed then is a system which can operate over almost any range to provide immediate access to a home on a remote basis quickly and conveniently.
SUMMARY OF THE INVENTION
The present invention is embodied in an apparatus for receiving an audio signal of the DTMF type and supplying it to a DTMF decoder. The DTMF decoder supplies a decoded signal to a microcontroller which in turn is connected to a non-volatile memory having codes stored therein. The non-volatile memory codes may be learned automatically via a variety of channels such as an RF channel, an Internet channel or the like. The system in one embodiment matches the DTMF code~to the stored code and the microcontroller provides an access output signal in response thereto. The access output signal is sent both to a wall control signal generator as well as to an RF transmitter. They then supply output signals respectively available for a wall controller and for a radio receiver of a garage door operator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings and especially to FIG. 1, an apparatus embodying the present invention is generally shown therein and identified by reference numeral 10. The apparatus 10 is an electronic apparatus for providing access to a dwelling on a remote basis.
The apparatus 10 is adaptable and may receive relatively short range signals over a distance of a few inches to a few feet to long range signals which may travel more than half way around the world. The apparatus 10 may, for instance, comprise a portion of or be connected to a garage door operator which will include a motor for operating a garage door. The system includes an electrical output port 12 and a radio frequency output port 14. The electrical output port 12 may provide electrical signals compatible with, for instance, a wall controller of a garage door operator. A radio frequency output port 14 may provide radio frequency signals, for instance, from an antenna which would be received by the receiving antenna of a garage door operator located a short distance away, for instance, within a garage or immediate adjacent to the garage.
In order to actuate the device in a preferred embodiment a listening device such as a microphone 20 is connected by a line 22 to electronics 24 which are conventionally and which may be used for the detection of DTMF type signals of the type which might be emitted in an audio stream from a DTMF encoder of the type which might be included for instance in a cellular telephone.
No electrical connection need be made between the microphone 20 and the DTMF encoder. It merely needs to "hear" the tone codes which are then detected by the detector 24 which forwards the signal to a microcontroller 26 which will then convert and represent the tone codes as a code and send a signal to the control interface for the electrical access control 30 or to an RF generator 32 to provide the RF access signal at the unit 14.
The unit may also include a video camera such as a CCD camera 40 connected via a cable 42 to the microcontroller 26. This would provide an input indication to the microcontroller 26 as to the presence of an individual and may also be used to send a video signal from the camera via a packet switched network interface 50 to an Internet or intranet 52 which may remotely supply information about the person attempting to gain access to the garage door or other portions of the interior of the dwelling.
While it is often desirable in order to conform with standards making bodies such as Underwriters Laboratory to only provide final access authorization through a channel which can only be locally accessed requiring a person to be within a very short distance for instance of the garage door operator. Pre-authorization for that person or class of persons can be provided over a relatively long distance for instance over the Internet. Signals may be received over a phone network connection 60, by pager network connection 62, or from the Internet 52 through the Internet interface 50 being supplied to the microcontroller 26 to provide preauthorization for a subset of persons such as delivery persons and the like in order to limit the likelihood that the system 10 may be spoofed into allowing an unauthorized person to enter the premises. A radio frequency receiver 70 feeds an RF receiver and detector circuit 72. The radio receiver 70 may be similar to a radio receiver in a garage door operator it may be a super-heterodyne receiver or a super-regenerative receiver either being capable of receiving an amplitude modulated, a frequency modulated, a pulse code modulated signal, or the like. However, the receiver only receives a relatively short range signal from an RF transmitter, such as a garage door operator transmitter. The signal is then supplied to the microcontroller 26 which can compare it with a code stored in the non-volatile memory 27 and take action to open and close a garage door or a door of a dwelling, or the like.
In addition, another local method of detection is through the use of a fingerprint identification system 80 connected via a line 82 to a fingerprint information interface 84 which performs fingerprint processing for identification. The fingerprint information interface 84 feeds the fingerprint signal to the microcontroller 86 to actuate either the electrical connection access control device 12 or the RF signal access control device 14. A
display 90, which might be a liquid crystal display, a light emitting diode display, a vacuum fluorescent display, or the like, provides a local output to a user to indicate the state of the apparatus 10 for instance to provide information such as enable, disabled.
The system 10 also can be preprogramed, for instance by a vendor, that a package will be received on a certain date and a certain time. The display 90 will indicate that the system 10 has received that message.
It also has provided that it remotely, for instance over the Internet 52, at a phone network connection to the owner of the dwelling. After the authorized person has delivered the package cycling of the controller may be indicated on the display 90 as well and an output indication may be provided via the Internet 52, phone network 60, pager network 62, or the like, remotely to the person having provided the access authorization to indicate that the transaction of completed.
One advantage of using the local fingerprint identification systems in combination with the remote information transfer channels, whether over the phone w line, pager network, or the Internet, resides in allowing data representative of a particular fingerprint or thumbprint to be transferred from a remote location to the microCOntroller 26 and stored in the non-nolatile memory 27 in a compressed or uncompressed form. That data would then be used to match with a fingerprint presented to the fingerprint identification device 80.
This allows the system to be custom configured on the fly for allowing access to a new temporary user via the fingerprint identification channel. In addition, the system l0 can have permissions provided to it remotely to allow for only a limited number of access or attempts to access via the fingerprint identification channel. That a particular fingerprint will not provide access after the transaction has been completed. Such access also can be limited on a time and date basis through either local loading or remote loading via the Internet or the like.
A further advantage of the system is that the return messaging, which can occur over the Internet channel, pager channel, phone network channel or the like, allows messages to be sent to the company whose drivers or repair personnel are providing the service.
This indicates that the authorized person has arrived at the dwelling at a particular date and time. In this way it allows the service-providing company to determine whether the person will be able to complete his or her scheduled tasks for the day or will need to reschedule some tasks for a later time.
_ g _ In addition, either through the fingerprint channel or the other authorization channels, a child may have authorization to come and go in the house. The system 10 will provide a parent or other authorizing party with information at their office or place of business on a real time basis that the child has arrived home and has been granted admission to the dwelling.
This provides parents with a heightened sense of security by knowing on a real time basis that their children have arrived home safely.
Furthermore the apparatus 10 can learn a touch code via the RF channel and store it in the non-volatile memory to provide a temporary touch code simulator function for operating the garage door operator. The temporary code is received during the learn phase from a touch code transmitter after having been placed in learn mode via a signal received over the RF channel.
In a second embodiment of the present invention an apparatus or system 200 may be retrofitted to an existing movable barrier operator or garage door operator 202 of a type which is currently commercially available.
The system 200 includes an external keypad unit 204 for monitoring outside a protected area such as a garage.
The system 200 has a standard keypad 206 with nine digit keys on it mounted on the garage, as well as a liquid crystal display 208 associated with the keypad 204 for displaying information related thereto. A
microcontroller 210 is connected to receive key input signals from the keypad 204 and to drive the LCD display 208.
A radio frequency transmitter 212 and a radio frequency transceiver 214 are also associated with the keypad 204.

A keypad 334 may provide input to a microcontroller 336 having on-board memory 338 including RAM and ROM. A plurality of dedicated function keys 340 would also be associated with the microcontroller 336 for providing control inputs, which would then be fed to an onboard radio frequency transmitter 342 which can emit coded radio frequency signals for receipt by the existing garage door operator.
A communication section 350 may communicate with the Internet 352 or other packet-switching network, with a biometric input device 354, such as a fingerprint reader, or the like, or with a camera 356. An authorized user on the Internet could access the barrier operator 302 and change its state and permission levels as well as determine whether the operator is open, closed or in a fault condition.
A radio frequency receiver 360 may receive RF
communications from the radio frequency transceiver 314 of the keypad transmitter 304 or it may receive communications from a door-position transmitter 362 associated with a garage door which indicates a position, of a garage door to other portions of the access control 300.

While there have been illustrated and described particular embodiments of the present invention, it will be appreciated that numerous changes and modifications will occur to those skilled in the art, and it is intended in the appended claims to cover all those changes and modifications which fall within the true spirit and scope of the present invention.
Referring now to the drawings and especially to FIG. 1, an apparatus embodying the present invention is generally shown therein and identified by reference numeral 10. The apparatus 10 is an electronic apparatus for providing access to a dwelling on a remote basis.
The apparatus 10 is adaptable and may receive relatively short range signals over a distance of a few inches to a few feet to long range signals which may travel more than half way around the world. The apparatus 10 may, for instance, comprise a portion of or be connected to a garage door operator which will include a motor for operating a garage door. The system includes an electrical output port 12 and a radio frequency output port 14. The electrical output port 12 may provide electrical signals compatible with, for instance, a wall controller of a garage door operator. A radio frequency output port 14 may provide radio frequency signals, for instance, from an antenna which would be received by the receiving antenna of a garage door operator located a short distance away, for instance, within a garage or immediate adjacent to the garage.
In order to actuate the device in a preferred embodiment a listening device such as a microphone 20 is connected by a line 22 to electronics 24 which are conventionally and which may be used for the detection of DTMF type signals of the type which might be emitted in an audio stream from a DTMF encoder of the type which might be included for instance in a cellular telephone.
No electrical connection need be made between the microphone 20 and the DTMF encoder. It merely needs to "hear" the tone codes which are then detected by the detector 24 which forwards the signal to a microcontroller 26 which will then convert and represent the tone codes as a code and send a signal to the control interface for the electrical access control 30 or to an RF generator 32 to provide the RF access signal at the unit 14.
The unit may also include a video camera such as a CCD camera 40 connected via a cable 42 to the microcontroller 26. This would provide an input indication to the microcontroller 26 as to the presence of an individual and may also be used to send a video signal from the camera via a packet switched network interface 50 to an Internet or intranet 52 which may remotely supply information about the person attempting to gain access to the garage door or other portions of the interior of the dwelling.
While it is often desirable in order to conform with standards making bodies such as Underwriters Laboratory to only provide final access authorization through a channel which can only be locally accessed requiring a person to be within a very short distance for instance of the garage door operator. Pre-authorization for that person or class of persons can be provided over a relatively long distance for instance over the Internet. Signals may be received over a phone network connection 60, by pager network connection 62, or from the Internet 52 through the Internet interface 50 being supplied to the microcontroller 26 to provide preauthorization for a subset of persons such as delivery persons and the like in order to limit the likelihood that the system 10 may be spoofed into allowing an unauthorized person to enter the premises. A radio frequency receiver 70 feeds an RF receiver and detector circuit 72. The radio receiver 70 may be similar to a radio receiver in a garage door operator it may be a super-heterodyne receiver or a super-regenerative receiver either being capable of receiving an amplitude modulated, a frequency modulated, a pulse code modulated signal, or the like. However, the receiver only receives a relatively short range signal from an RF transmitter, such as a garage door operator transmitter. The signal is then supplied to the microcontroller 26 which can compare it with a code stored in the non-volatile memory 27 and take action to open and close a garage door or a door of a dwelling, or the like.
In addition, another local method of detection is through the use of a fingerprint identification system 80 connected via a line 82 to a fingerprint information interface 84 which performs fingerprint processing for identification. The fingerprint information interface 84 feeds the fingerprint signal to the microcontroller 86 to actuate either the electrical connection access control device 12 or the RF signal access control device 14. A
display 90, which might be a liquid crystal display, a light emitting diode display, a vacuum fluorescent display, or the like, provides a local output to a user to indicate the state of the apparatus 10 for instance to provide information such as enable, disabled.
The system 10 also can be preprogramed, for instance by a vendor, that a package will be received on a certain date and a certain time. The display 90 will indicate that the system 10 has received that message.
It also has provided that it remotely, for instance over the Internet 52, at a phone network connection to the owner of the dwelling. After the authorized person has delivered the package cycling of the controller may be indicated on the display 90 as well and an output indication may be provided via the Internet 52, phone network 60, pager network 62, or the like, remotely to the person having provided the access authorization to indicate that the transaction of completed.
One advantage of using the local fingerprint identification systems in combination with the remote information transfer channels, whether over the phone w line, pager network, or the Internet, resides in allowing data representative of a particular fingerprint or thumbprint to be transferred from a remote location to the microCOntroller 26 and stored in the non-nolatile memory 27 in a compressed or uncompressed form. That data would then be used to match with a fingerprint presented to the fingerprint identification device 80.
This allows the system to be custom configured on the fly for allowing access to a new temporary user via the fingerprint identification channel. In addition, the system l0 can have permissions provided to it remotely to allow for only a limited number of access or attempts to access via the fingerprint identification channel. That a particular fingerprint will not provide access after the transaction has been completed. Such access also can be limited on a time and date basis through either local loading or remote loading via the Internet or the like.
A further advantage of the system is that the return messaging, which can occur over the Internet channel, pager channel, phone network channel or the like, allows messages to be sent to the company whose drivers or repair personnel are providing the service.
This indicates that the authorized person has arrived at the dwelling at a particular date and time. In this way it allows the service-providing company to determine whether the person will be able to complete his or her scheduled tasks for the day or will need to reschedule some tasks for a later time.
_ g _ In addition, either through the fingerprint channel or the other authorization channels, a child may have authorization to come and go in the house. The system 10 will provide a parent or other authorizing party with information at their office or place of business on a real time basis that the child has arrived home and has been granted admission to the dwelling.
This provides parents with a heightened sense of security by knowing on a real time basis that their children have arrived home safely.
Furthermore the apparatus 10 can learn a touch code via the RF channel and store it in the non-volatile memory to provide a temporary touch code simulator function for operating the garage door operator. The temporary code is received during the learn phase from a touch code transmitter after having been placed in learn mode via a signal received over the RF channel.
