Abstract
A method and system () for directing relief to individuals () requiring emergency assistance includes each individual in a building () carrying a respective transponder (). The transponders transmit a wireless emergency signal in response to actuation by an individual. A communication link () such as a local area network (LAN) runs throughout the building. Transceivers () located at known locations are connected to the link. Each transceiver has a unique identification and wirelessly receives an emergency signal transmitted by a transponder located within the vicinity of the transceiver. Each transceiver transmits the received emergency signal along with the unique transceiver identification to a controller () via the link. The controller processes a received emergency signal to determine the location of the individual requiring emergency assistance based on the unique identifications of the transceivers transmitting the emergency signal. The controller directs relief () to the determined location of the individual.
