Abstract: A multi-cell battery powered device can include at least one power input, a first power converter coupled between the power input and a battery bus, a second power converter coupled between the battery bus and a system load of the electronic device, a plurality of cells, and a plurality of primary battery protection switches. The primary battery protection switches can be selectively operable to couple the plurality of cells in: (1) a parallel configuration in which the cells are coupled to the battery bus so as to charge or discharge in parallel, (2) a series configuration in which the cells are coupled to the battery bus so as to charge or discharge in series, and (3) an isolated configuration in which at least one of the plurality of cells is coupled to the battery bus and at least one of the plurality of cells is disconnected from the battery bus.

Abstract: A voltage of a first pin that is one of several pins of an external connector of a system is measured, while the first pin is un-driven except for being pulled to ground through a first resistance, and a second pin of the external connector is being used as a power supply rail of the system. The measured voltage is compared to a short circuit threshold and in response to that threshold being exceeded, the power supply voltage on the second pin is reduced. In such an embodiment, no test stimulus needs to be applied to any of the pins of the external connector. Other embodiments are also described and claimed.

Abstract: Electronic devices may contain electrical systems in which electrical components are mounted on a substrate such as a printed circuit board. The electrical components may include surface mount technology components. Multiple surface mount technology components may be stacked on top of each other and beside each other to form an electrical component that minimizes the amount of area that is consumed on a printed circuit board. Noise suppression circuits and other circuits may be implemented using stacked surface mount technology components. Surface mount technology components placed on the printed circuit board may be pushed together and subsequently injection molded to form packed component groups. An integrated circuit may be mounted to the printed circuit board via an interposer and may cover components mounted to the printed circuit board. An integrated circuit may be mounted over a recessed portion of the printed circuit board on which components are mounted.

Abstract: A mobile communications device contains at least two microphones. One microphone is designated by a selector to provide a voice dominant signal and another microphone is designated to provide a noise or echo dominant signal, for a call or a recording. The selector communicates the designations to a switch that routes the selected microphone signals to the inputs of a processor for voice signal enhancement. The selected voice dominant signal is then enhanced by suppressing ambient noise or canceling echo therein, based on the selected noise or echo dominant signal. The designation of microphones may change at any instant during the call or recording depending on various factors, e.g. based on the quality of the microphone signals. Other embodiments are also described.
