    Abstract: The battery charging process monitors the battery charging pockets waiting for an indication that a battery or a phone-battery combination has been inserted into their respective pockets. The first battery that is inserted is the high priority battery and is charged first while any subsequent battery inserted into a charging pocket has no power applied until the high priority battery is charged. If the phone enters a call while in the charger, it becomes the high priority battery if it was not already. In this case, power is removed from the individual battery and applied to the phone-battery combination until the call has been completed. At this point, the process returns the high priority status to the battery that had it prior to the call interrupt.

    Abstract: The system includes a first mechanism for receiving a feedback signal and providing a charging signal to the battery over a first electrical path when the feedback signal indicates that the battery is not fully charged. A secon d mechanism measures a voltage state of the battery via second and third electrical paths and provides the voltage state as the feedback signal to th e first mechanism in response thereto. In the specific embodiment, the first mechanism is a controllable power supply and the second mechanism is a sensi ng circuit. The sensing circuit includes a subtractor circuit that subtracts th e voltage on the second electrical path from the voltage on the third electric al path and provides the feedback signal in response thereto. The second electrical path includes a wire connected between a first terminal of the subtractor circuit and a positive terminal of the battery.

    Abstract: Un procesador de demodulacion integrado, utilizado en un modem para un sistema de comunicaciones de espectro extendido, reduce o limita las señales de recepcion de trayectoria multiple y posteriormente utiliza un procesador de transformacion de tiempo fraccionado para procesar las señales multiples en una sola serie de resultados de decision flexible o suave. El procesador de demodulacion utiliza un solo dispositivo de transformacion que opera con base en fracciones de tiempo. Las salidas del dispositivo procesador salen en cascada a través de un procesador de cable coaxial que, con base en fracciones de tiempo, opera sobre las señales correspondientes a cada señal de recepcion de trayectoria multiple. Los resultados procesados se descodifican por máximos duales para proporcionar datos de decision flexible o suave.

    Abstract: A system for charging a battery over a linear or nonlinear circuit. The system includes a first mechanism for receiving a feedback signal and providing a charging signal to the battery over a first electrical path when the feedback signal indicates that the battery is not fully charged. A second mechanism measures a voltage state of the battery via second and third electrical paths and provides the voltage state as the feedback signal to the first mechanism in response thereto. The voltage state accounts for voltage drops occurring over the circuit. In the specific embodiment, the first mechanism is a controllable power supply and the second mechanism is a sensing circuit. The sensing circuit includes a subtractor circuit that subtracts the voltage on the second electrical path from the voltage on the third electrical path and provides the feedback signal in response thereto. The second electrical path includes a wire connected between a first terminal of the subtractor circuit and a positive terminal of the battery. The second electrical path also includes a first sensing resistor connected between an output of the power supply and the first terminal of the subtractor circuit. The third electrical path includes a wire connected between a second terminal of the subtractor circuit and a negative terminal of the battery. The third electrical path also includes a second sensing resistor connected between a ground and the second terminal of the subtractor circuit.
