Abstract: A system for providing an accurate indication of the remaining life of a battery. The system includes a first circuit that provides a control signal (46). A second circuit employs an internal resisitance value of the battery (34) and a battery voltage to provide the indication of remaining battery li fe in response to the control signal. In a specific embodiment, the second circuit includes a third circuit (36) that measures the internal resistance of the battery in response to the control signal. The third circuit also includ es a circuit for measuring an output current and an output voltage of the batte ry (34) at varying battery loads. The circuit for measuring an output current includes an ammeter (40) and a switching load (42). In a more specific embodiment, the switching load (42) is implemented as a transmitter that is selectively activated via the control signal. A fourth circuit, included in the second circuit, provides the indication of remaining battery life in response to the internal resistance. The fourth circuit also includes a circuit for selecting a battery discharge curve in accordance with the internal resistance. Software running on the first circuit generates the estimate based on the discharge curve, which is subsequently displayed via a display.

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. However, the PDA is operable to receive information from the user through the display and display information to the user on the display when the wireless telephone is in the power-off state.
