Abstract: A telephone has several lists of phone numbers. Each phone number within a list has a number of digits which is not less than a predetermined minimum number, and not more than a predetermined maximum number. The maximum number is the “size” of the list. When a digit is entered, the phone compares (1B) the number of digits entered to the lists, and selects (1C) the list of the smallest size which is greater than or equal to the number of digits entered. That list is searched (1D) and the results displayed (1E) when the search is complete. If another digit is entered during the search (1F), the comparing (1B) and list selecting (1C) steps are repeated.

Abstract: A system and method for reducing power consumed by an integrated electronic device. The device includes a personal data assistant (PDA) unit and a wireless telephone integrated in a common housing. A common display on the housing is used for displaying messages from both the PDA and the wireless telephone to a user. A controller, coupled to the wireless telephone, places the wireless telephone in a power-off state after expiration of a predetermined period of time following cessation of voice traffic activity on the wireless telephone. The controller switches the wireless telephone from the power-off state to a power-on state if, during operation in the power-off state, a user begins an attempt to place an outgoing call with the wireless telephone. The wireless telephone is unable to receive an incoming call when the wireless telephone is in the power-off state.

Abstract: A system for providing immediate access to detailed information about a wireless call. The system includes a first mechanism for placing a wireless call. A second mechanism times the call to provide a call duration value. A third mechanism computes the detailed information from the call duration value and a predetermined value associated with the call. A fourth mechanism displays the detailed information. In a specific embodiment, the predetermine value is a billing rate associated with the call and the detailed information is expense information. The third mechanism includes a computer that runs software for computing the detailed information from the call duration value and the billing rate. The software includes a routine that detects when the wireless phone is being used for a call and times the call. The software also includes a mechanism for providing user-selectable parameters for controlling the third mechanism.
