Abstract: An enhanced telephone emulation computer system including a minidialer program for controlling a computer to add telephony functions which can be invoked from whatever active program is currently controlling the computer. The minidialer program controls the computer to alter its processing depending upon the context existing at the time when a mouse click or hot key combination event is detected indicating the user wishes to invoke a telephony function. The minidialer program determines whether the user has highlighted any text or numbers in the active window of the application currently controlling the computer and whether the highlighted material is a name or a phone number, and if a name, whether the name is stored with a phone number in a phone book or file maintained on the computer. Processing and telephony menu options displayed as available also depend upon whether the user is or is not on the phone at the time the mouse click or hot key event occurs.

Abstract: Apparatus and methods are provided for regulating the power consumption within a wireless communications mobile handset. A base station transmits an RF power output designating signal that indicates a desired level of the RF power output from the mobile handset. The mobile handset receives the RF power output designating signal, where it is used to set the level of the DC power supplied to the mobile handset. In this manner, the minimum amount of power necessary to maintain linear operation of the mobile handset is expended in the mobile handset. The DC power level is set by internally generating a control signal. The level of the control signal is dictated by the desired level of the RF power output as indicated by the received RF power output designating signal. The control signal is then applied to an RF amplifier circuit contained within the mobile handset to set the DC power level.
