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.

Abstract: A microphone port design for a handheld device is disclosed. The microphone port design includes an elongated channel disposed in a first surface of the handheld device. A microphone port is located within the channel to reduce unwanted noise caused by air pressure build up around the microphone port opening due to coverage of the opening by a user's finger.

Abstract: A system and method of improving the efficiency in the power consumption of an audio system. In essence, the technique is to adjust the power delivered from the power supply to the analog section, such as the power amplifier, in response to the volume level indicated by the volume control module and/or in response to the detected characteristic of the input audio signal. Thus, in this manner, the analog section is operated in a manner that is related to the level of the signal it is processing. Additionally, the system and method also relate to a technique of adjusting the dynamic ranges of the digital signal and the analog signal to improve the overall dynamic range of the system without needing to consume additional power.
