Abstract:
1. A personal monitoring system, comprising: a wireless network; a sensing device configured for coupling to a user, the sensing device comprising a network interface configured for coupling the sensing device to the wireless network and a barometer configured for measuring barometric pressure that is indicative of a location of a user in relation to sea level; and a processor configured for determining a baseline elevation of the user based on data indicative of a first barometric reading and corresponding to a first location of the user, the processor further configured to determine a change in elevation of the user based on data indicative of a second barometric reading and corresponding to a second location of the user relative to the baseline elevation, the processor further configured for transmitting data indicative of the baseline elevation and the change in elevation to a computing device via the wireless network which the computing device may use to locate the user.
