Abstract: A mobile terminal configured for use in a mobile telecommunications network, the mobile terminal having an emergency notification facility and an identifier, the identifier usable by the network to recognize the mobile terminal as having the emergency notification facility and to change a system access priority for the terminal, where required. Preferably, the terminal also includes a sensing means configured to determine when the mobile terminal is in motion and/or associated with a vehicle and notify the network of such, in order to allow the network to change the system access priority based upon whether or not the terminal is in motion and/or associated with a vehicle. In this regard, mobile terminals with an emergency notification facility, particularly when moving or in a vehicle, are given a higher priority so that an emergency call can be quickly dispatched in the event of an accident.

Abstract: A passive transponder for use in an interrogator-responder communication system is disclosed, including a first signal receiving element having a variable reflection property, a code signal generator for supplying a code signal, a modulating device responsive to the code signal for varying the signal reflection property of the first signal receiving element, and a power supply for supplying direct-current operating power to the code signal generator and to the modulating device, the power supply including a second signal receiving element for receiving a second electromagnetic signal having a second frequency different from the first frequency, and an a-c to d-c converter for converting the second signal to direct-current power.
