A system for monitoring an area and sounding an alarm comprising. The system employs one or more sensors positioned about the protected area. Each sensor has one or more pulse generators generating one or more pulses each with a preassigned pulsewidth. The sensors are connected to a controller by a single wire. The controller sounds an alarm upon receipt of one or more pulses and identifies the sensor actuating the alarm by the measured pulsewidth.

Alarm sensor multiplexing

A vehicle convenience system comprising a wireless transmitter, having at least one switch therein, for communicating multiple channel commands to an expander, the expander responsive to activation of the transmitter and the expander having at least one expander output responsive to the channel commands received from the transmitter; said expander outputs being programmable to at least one user selectable mode.

Channel expander for remotely controlled automotive security and

Remote control transmitter

A method of indicating a degree of incoming threat to an electronically secured area comprising the steps of sensor sensing a degree of threat delivered to a secured area and generating an electric signal proportional to the degree of threat; analyzing the signal to determine if it is a low degree of threat or a high degree of threat; and producing either a first pulse representing low degree of threat or separately producing the first pulse and a second pulse representing a signal having both low degree of threat and high degree of threat.

Advanced method of indicating incoming threat level to an electronically

A system for monitoring and controlling an area comprising a controller for controlling system operational functions and responsive to at least one remote-control transmitter. The transmitter transmits system commands to the controller in a code word having a fixed word and a hopping word therein. The fixed and hopping words are scrambled using a format word resident in the transmitter and sent to the controller only during a learn mode.

System having advanced embedded code hopping encryption and learn mode

A remotely controllable vehicle system for generating a response to an incoming threat to a secured area and/or control of user selectable convenience features, comprising a wireless transmitter having at least one switch for generating and transmitting a signal encoded with a code word having at least one identification word; a receiver for receiving the signal; a decoder for decoding the code word from the signal; a controller responsive to a command word embedded in the code word only if an identification word, embedded in the code word, is identical to at least one authorized identification word stored in a memory accessible to the controller; a learn mode for programming a new identification word of a new transmitter in the memory as an authorized identification word only if multiple groups of the code words are transmitted from the transmitter and received by the controller.

Learn mode for remote transmitters

A system for monitoring and controlling an area comprising a controller for controlling system operational functions; at least one remote-control transmitter for transmitting system commands to the controller in a code word having a fixed word and a hopping word therein; the fixed word comprising at least one fixed data bit and the hopping word comprising at least one changing data bit, wherein the hopping word changes its binary value from transmission to transmission of the system commands; and, means for scrambling bits of the fixed word and bits of the hopping word within the code word.

Advanced embedded code hopping system having master fixed code encryption

A vehicle convenience system comprising a wireless transmitter, having at least one switch therein, for communicating multiple channel commands to an expander, the expander responsive to activation of the transmitter and said expander having at least one expander output responsive to the channel commands received from the transmitter; the expander outputs being programmable to at least one user selectable mode.

A security system for monitoring a protected area and sounding an alarm including a plurality of sensors arranged about a protected area for sensing incoming threat, device for generating at least one pulse for each sensor activated by the incoming threat to the area, an alarm controller for receipt of the pulses and sounding of an alert, and a single wire connecting outputs of the sensors to the controller for transmitting the pulses generated by the plurality of sensors to the controller.

Advanced embedded code hopping system

A system for monitoring and controlling an area comprising a controller for controlling system operational functions; at least one remote control transmitter for transmitting at least one system command to said controller in a code word having a fixed word and a hopping word therein; the fixed word having an identification code for selective control of the controller, the identification code programmed therein, and a channel code for issuing high and low security commands to the controller; a hopping algorithm for modifying the hopping code of the transmitter n-times in response to n-times activation of said transmitter and for modifying the hopping word m-times within the controller upon receipt of the code word m-times from said transmitter; and, a bypass mode for bypassing the code hopping algorithm and for controlling system functions in response to the controller receiving the low security command.

High throughput embedded code hopping system with bypass mode

A battery adapter for charging a spare cellular telephone battery in a vehicle charging unit, the adapter comprising a charging unit, having first power supply connections positioned for electrical coupling with corresponding second connections of a battery for use with a cellular telephone and a clip having an anchored biased pivot end and a hook end, wherein the hook end is resiliently movable about the pivot end for urging the hook end into a corresponding cavity of the cellular telephone for retainment of the cellular telephone in the charging unit and for urging the first and second power supply connections together to maintain electrical coupling thereof. The adapter is adapted to engage with the battery, for charging it while the cellular telephone is outside the charging unit and the adapter having a cavity therein positioned for receipt of the hook end of the clip for retaining it and the battery in the charging unit and to provide electrical contact between the first and second power supply connections.
