Abstract: A battery device for powering a working device. The battery device including a locking component configured to be capable of extending out of a housing of the battery device or retracting into the housing to engage with or disengage from the working device. The battery device further including an operation component configured to be capable of being actuated by an operator. The battery device further including a transmission mechanism configured to transmit a motion of the operation component to the locking component when the operation component is actuated so as to make the locking component disengage from the working device. Wherein the transmission mechanism includes at least two connecting rods which are sequentially overlapped in a force transmission direction.

Abstract: A collector plate assembly includes a collector plate and a collector plate support, the collector plate having a welding part for welding to a terminal of a battery unit, and the collector plate being installed in the collector plate support in such a way that the welding part is exposed by the collector plate support. A battery pack includes a housing; a battery support, enclosed by the housing and supported in the housing, the battery support being electrically connectable to an electric tool to supply electric power to the electric tool; and a collector plate assembly including a collector plate support and a collector plate installed in the collector plate support.

Abstract: A battery pack including a housing; and two or more battery cells located in the housing. The two or more battery cells interconnected by a configurable connector which is configured to enable electrical connections between the two or more battery cells. The configurable connector contains a plurality of first electrical terminals connected to the two or more battery cells, and a terminal holder adapted to be removably connected to the plurality of the first electrical terminals. The terminal holder is adapted to be installed to the housing in a first orientation at which the two or more battery cells are electrically connected, or in a second orientation at which the two or more battery cells are not electrically connected. The terminal holder contains a plurality of second electrical terminals.

Abstract: There is provided battery cell assembly for a power tool battery pack. The battery cell assembly comprises a cell housing, a battery cell and a cell strap. The battery cell define a pole and is supported by the cell housing. The cell strap comprises a leg for electrically contacting the pole. The cell housing defines a first formation and the cell strap defines a second formation configured to engage the first formation so as to align the leg with the pole.

Abstract: A mouse includes a base and a cover. The base includes a bottom panel with a sensor. The cover includes a sensing area. A reference point and a number of sensing points are located on the sensing area. A displacement of a mouse arrow on a screen is defined as a displacement of the sensing points from the reference point. The sensor senses light from the sensing area. When one of the sensing points is shielded, the sensor sends an operating signal to a control module of an electronic device for generating a displacement of the mouse arrow on the screen corresponding to the shielded sensing point.

Abstract: An apparatus is used for testing an embedded device with identification information. The apparatus includes a storage device. A monitoring program and a testing program are installed in the storage device. The monitoring program receives the identification information from the embedded device through a serial connection formed between the apparatus and the embedded device after logging in to the embedded device through the serial connection. The testing program is copied to the embedded device to test the embedded device by the monitoring program through a network connection formed between the apparatus and the embedded device. A system and a method for testing the embedded device are also provided.

Abstract: A testing device is provided to include a pre-boot execution environment (PXE) server, a dynamic host configuration protocol (DHCP) server, and a computer. The computer is connected to the PXE server and the DHCP server via a network. The PXE server includes an image file stored therein, a communicating module of server terminal and a communicating module of client terminal. The computer includes a network device for supporting PXE functions. A testing method is provided to include following steps: connecting the PXE server and the DHCP server to the computer via the network, the DHCP server assigning an IP address to the computer, the computer downloading the communicating module of client terminal from the PXE server, for communicating with the communicating module of server terminal, and the image file being run to test the computer.
