Abstract: A system for programming a code for a wireless short range RF transmitter, for example, an emergency call transmitter or keyless entry, has a RF transmitter that transmits an RF signal containing a code. A code receiver receives a signal containing a code and a processor is operative with the code receiver and RF transmitter. A programming fixture receives the wireless transmitter within a receptacle, and the code receiver within the wireless transmitter and the code transmitter are operative with each other for transmitting a signal containing a new code from the programming fixture to the wireless transmitter. A processor is operative with the code transmitter for modulating the signal and imparting a data stream from the code transmitter to the code receiver and processor and programming a new code. The code receiver and transmitter could be coils to form a transformer.

Abstract: A system and method determines the location of a resident during an emergency within a monitored area having a plurality of residences such as when a wireless emergency call transmitter is activated. In accordance with one aspect, a wireless emergency call transmitter is positioned within the area and includes a radio frequency (RF) transmitter that is resident activated during an emergency for transmitting an RF signal containing a transmitter code indicating the identity of the emergency call transmitter. The emergency call transmitter includes a receiver section that receives an infrared or acoustic signal containing a location code identifying a room or other location. This signal is received from a location monitor that had received the RF signal from the emergency call transmitter. In response to receiving the infrared or acoustic signal, the emergency call transmitter transmits an RF signal containing the location code.

Abstract: A central smoke detection system for a building having multiple rooms utilizes low cost commercial smoke detectors in each room. Each detector includes a steady high current alarm mode, a low current idle mode and a high pulse current test mode. A central power source supplies power to the detectors via one common lead and a separate power lead to each detector. A resistor in each power lead at the central location provides for monitoring of the mode of each smoke detector. A central monitor operates a visual smoke alarm responsive to the steady high current mode which indicates the room in which a detector is in the alarm mode and a visual fault alarm responsive to the absence of the high test pulse current indicating the room in which a detector is inoperative. A common central smoke and fault alarm, both audible and visual is also provided.

Abstract: The environmental control system of the present invention is used in a multiple room structure which includes independently actuatable heating and cooling devices in each room. This system operates by monitoring the ambient air temperature in each room and by controlling the operation of each heating and cooling device to achieve a desired ambient air temperature in each room. The structure of the present invention includes a room status indicator which indicates the occupied or vacant status of each room. A centrally located control panel permits an operator to assign heating mode and cooling mode temperature limits to each room. A temperature sensing and control unit is positioned in each room and is coupled to the heating and cooling device in each room. The temperature sensing and control unit measures the ambient room air temperature, determines the operating mode of the heating and cooling device and controls the operating mode of the heating and cooling device in response to a control signal.
