Abstract: The invention provides a communication device for automatically switching its communication modes and an operating method thereof. The communication device includes a photodetector module, a processing module, and a coder-decoder (CODEC) module. The photodetector module is configured to sense variation of light from an object to obtain an optical signal, and is configured to convert the optical signal to an electric current signal, wherein the light varies with a position of the object from the communication device. The processing module is connected to the photodetector module and is configured to direct the CODEC module to switch between audio channels of the communication device according to the electric current signal so as to change a communication mode of the communication device in a phone call.

Abstract: A system for processing packets in a distributed architecture system includes a main control board, at least one service board, and at least one interface board. The system determines a specified CPU corresponding to a received packet; and, by the service board corresponding to the CPU, processes the received packet. The received packets are processed in the service board corresponding to the specified CPU. Therefore, the packets are evenly distributed to all service boards for being processed, the workload of the main control board is relieved, the service throughput is increased significantly, and the packet processing efficiency of the whole architecture is improved.

Abstract: A direct current (DC)-to-DC conversion apparatus is provided. The provided DC-to-DC conversion apparatus is composed of two boost circuits, in which inputs of both boost circuits are connected in parallel, and outputs of both boost circuits are connected in series. Accordingly, when the provided DC-to-DC conversion apparatus is operated, the DC input power would be firstly sampled and determined, and then the operations of the first and the second switch devices disposed therein would be controlled in response to the sampled-determined result, such that both boost circuits would be respectively operated in different input conditions, for example, the input is normally-connected or the input is reverse-connected. Accordingly, regardless of the input of normal connection or the input of reverse connection, the provided DC-to-DC conversion apparatus can perform the function of DC-to-DC conversion, thereby enabling the applied product to be normally operated even the input is reverse-connected.

Abstract: A commutator 10 for an electric motor comprises a plurality of commutator segments supported by a base. The segments have an electrically conductive body portion 14 and at least one electrically conductive foldable tang 16 provided on the body portion 14 for engaging a winding lead wire 44 of an electric motor. The foldable tang 16 has a proximal end 18 on or adjacent to the body portion 14, and a distal end 22 remote from the proximal end 18. A wire-accommodating portion 30 is provided on or adjacent to the foldable tang 16, so that, when the tang 16 is folded, the wire-accommodating portion provides a predetermined gap 56 for the winding lead wire 44.
