Abstract: An immobilization system for a vehicle for assisting law enforcement includes a first remote control device, which transmits a predetermined wireless control signal, and a second remote control device, which includes a first directional antenna for transmitting a selectable wireless control signal in a first direction and a second directional antenna for transmitting a wireless enable signal in a second direction. The second remote control device includes an externally operable device for selecting the wireless control signal and the enable signal to be transmitted. A receiver is included for receiving the control signal and the enable signal with the predetermined control signal being substantially unique to the receiver. A device for disabling a vehicle by police, in response to either the predetermined control signal or the selectable control signal, is provided for allowing capture of those assailants seeking to escape by use of a motor vehicle.

Abstract: A portable paging system for responsive signaling between a first person and a second person. The portable paging system includes a housing. The housing has a top side, a bottom side and peripheral wall integrally coupled to the bottom and top sides and extending therebetween such that the housing is generally hollow. A microprocessor is adapted to receive a transmitted signal and illuminate a light. The microprocessor is securely mounted in the housing. A light is securely mounted to the top side of the housing. The light is electrically coupled to the microprocessor. A receiver receiving a transmitted signal is positioned in the housing and operationally coupled to the microprocessor. A transmitting device selectively transmits a signal to the receiver over a distance of less than one mile.

Abstract: A signalling system providing communications between a controller and a remote unit in a network element is provided. The signalling system comprises a first communication module associated with the controller, a second communication module associated with the remote unit and a communication link for the first and second communication modules. The first communication module generates a command signal and a downstream monitoring signal for the remote unit. The second communication module receives the command signal and the downstream monitoring signal and generates the status signal and the upstream monitoring signal. The communication link carries the signals. The first communication module monitors for receipt of the upstream monitoring signal and the status signal and determines status of the communication link and the remote unit utilizing results of monitoring for the receipt of the upstream monitoring signal, the status signal and the command signal.

Abstract: In the access control system, a code transmitter-end transceiver unit and a vehicle-end transceiver unit emit signals approximately synchronously on approximately the same carrier frequency. As a result of superimposition, a new code signal arises and its code information item is compared with an expected set point code information item. When there is correspondence, an enable signal for locking or unlocking or releasing the immobilizer is generated. The synchronous transmission/reception makes illegitimate monitoring more difficult.

Abstract: An interface assembly with an animated character/prop has at least one speaker for generating language and mechanisms for generating correlated movement. A logic controlling device has a plurality of inputs and outputs and is adapted to configure and synchronize message request signals from the various sensors, relays, thermostats, user controls and the like, with the appropriate audible words and movement commands from the generating devices as required to convey messages relating to the environment to the user. The interface assembly provides an audio component adapted to receive output signals from the logic controlling device to actuate the speaker. The interface assembly provides a movement component adapted to receive output signals from the logic controlling device to actuate the mechanisms for generating movement. The interface assembly provides a drive converter assembly operatively coupled to and adapted to convert and transfer signals between the movement component and the character/prop.

Abstract: An identification transponder for transferring an identification code to a base station by varying an RF-signal transmitted by the base station in a rhythm which corresponds to the identification code. The identification transponder comprises an identification code generator, a rectifier; and a load transistor. The load transistor is arranged in such a manner that it performs two tasks: the task of rectifying the RF-signal to provide the DC supply voltage for the transponder, and the task of supplying a variable load to the rectifier to thereby vary the RF-signal transmitted by the base station.

Abstract: Time elapsed from the time when the sensor cover is opened and power supply to the fingerprint sensor is turned from off to on is counted and when there is no fingerprint image read-in command within a specified period of time power supply to the fingerprint sensor is turned off. Even if power supply to the fingerprint sensor is turned off, when a fingerprint image read-in command executes power supply to the fingerprint sensor is turned on and read-in of a fingerprint image commences. If a fingerprint image read-in command executes when the sensor cover is closed, that command is invalidated. In such a configuration, the opening and closing of a sensor cover works in synchronicity with on/off control of power supply for a fingerprint sensor and even when the sensor cover is open, wasteful electricity consumption through power supply continuing if the fingerprint sensor is not used within a specified period of time is prevented.

Abstract: A door alarm system and a door lock assembly having an interior rose having a request to exit (REX) switch. The alarm system generates an open door alarm when a door into a secured area is open unless the REX switch generates a REX signal indicating that the door was opened by someone on the inside of the secured area. Mechanical isolation in the door lock assembly prevents a forcing movement on the outside of the door from causing a false generation of the REX signal.

Abstract: Reliable and efficient activation and deactivation control of a number of electronic products (P1, P2, P3) is effected by activation of one of the products by emission of an activation command specific to the product and controlling performance and/or functionality of the product by speech commands. Emission of the activation command specific to the one product is accompanied by emission of a deactivation code causing deactivation of any other of the number of electronic products.
