Abstract: A wireless device (100) having an optimum alert sequence definition analyzes its environment, including time and type of incoming call, and selects an appropriate alert signal sequence. A central processing unit (114) included within the device (100) is responsive to a transmitted signal from an external communications device to generate active and passive sonic sensing. The reflected signal received through the microphone (110) and a predetermined set of values or ranges stored in a memory (102) coupled to the central processing unit (114) are used as input for a program of instructions tangibly embodied in a programmable storage device executable by the central processing unit (114). Based upon processing of this reflected signal, the central processing unit (114) determines which alert signal is optimum given the environment.

Abstract: In one aspect, the present invention discloses a communication device (see, for example, FIG. 5), such as a mobile unit (e.g., a cellular telephone handset) or a stationary unit (e.g., a cellular telephone base station). The communication device utilizes global positioning system (GPS) information 560 within a Doppler profile generator 540. For example, in a mobile unit, the GPS information would typically be generated at the device. A receiver 520 is coupled to the Doppler profile generator 550. The receiver 520 utilizes Doppler profile information in translating a received wireless signal into user information.
