Abstract
A social alarm system provides location detection within a dwelling. A personal radio trigger unit is carried by a client and transmits an alarm signal in response to a triggering event, such as by a manual alarm button or an automatic fall detection circuit. A client unit is operable to receive the alarm signal and initiate an alarm call to a remote monitoring center over a communications network. A plurality of radio receptor nodes monitor the wireless RF transmissions from the personal radio trigger to report respective received signal strength values. A location finder unit determines a location of the personal radio trigger, by using absolute error calculations and/or shape error calculations against previously recorded known locations in the dwelling.
