Abstract:
A remote communication unit arbitration system comprising:a. a housing; b. a control system associated with said housing and having a memory; c. communication electronics operatively associated with said control system and having a transmitter for transmitting signals to a remote communication unit and a receiver for receiving signals from the remote communication unit; and d. attribute monitoring electronics having an output associated with said control system and an input associated with said communication electronics, said attribute monitoring electronics adapted to: i. monitor an attribute of a signal received by said communication electronics, the attribute being indicative of the relative proximity between the remote communication unit and the housing, and ii. provide said control system with a new proximity value indicative of the relative proximity between the remote communication unit and the housing; e. said control system adapted to: i. compare said new proximity value with a prior proximity value from a prior communication with the remote communication unit, and ii. determine a relative proximity of the remote communication unit to the housing as compared to another communicative device that communicates with the remote communication unit associated with a prior communication based on the new and prior proximity values.
