Abstract: A real-time communication system includes a cloud server, multiple user devices having respective real-time communication software for communicating with the cloud server, and multiple dynamic expression rendering devices one-to-one communicating with the user devices respectively. A transmitting user device encodes and transmits a transmitter data, a receiver data and a dynamic expression ID of a selected dynamic expression. The cloud server decodes and transmits the transmitter data, the receiver data and the dynamic expression ID of the selected dynamic expression to a receiver user device. Based on the received dynamic expression ID, the real-time communication software of the receiver user device finds the dynamic expression.

Abstract: A computer stick docking system and a power management method thereof are provided. The computer stick docking system includes a docking station and a computer stick device. The docking station is configured to receive a display device and a computer stick device, including a docking battery and a docking HDMI interface circuit. The computer stick device includes a computer-stick controller and a computer-stick HDMI interface circuit. The computer-stick controller is configured to load an operating system. The computer-stick HDMI interface circuit, coupled to the computer-stick controller, is configured to request battery power information of the docking battery from the docking station after it is powered on and the computer-stick HDMI interface circuit is connected to the docking station.

Abstract: A tightening device for positioning a worktable of a machine tool to a base includes a saddle member disposed on the base, and a positioning carrier member carrying the worktable and movable relative to an abutment wall of the saddle member. An elongate adjusting member has a force-delivering end spaced apart from the abutment wall, and a middle threaded segment threadedly engaged with the positioning carrier member such that the force-delivering end is movable towards or away from the abutment wall. A force transmitting member is loosely connected to the positioning carrier member, and is configured such that a spiral force resulting from a screw-in movement is taken up by a proximate end thereof from the force-delivering end, and is transformed to a translation force that moves a distal end thereof to tightly engage the abutment wall.

Abstract: An abutment plate assembly for a cutting machine includes an abutment plate unit, an extension plate unit, and a locking unit. The abutment plate unit includes a sliding rail unit having a generally T-shaped cross section. The extension plate unit is formed with a slide slot having a generally T-shaped cross section and engaging the sliding rail. The locking unit includes a pressing member movable vertically within the slide slot, a resilient member for biasing the pressing member to move away from the abutment plate unit, and a rotary lever unit. The rotary lever unit is rotatable so as to move the pressing member toward the abutment plate unit until the pressing member presses the extension plate against the abutment plate unit to thereby lock the extension plate unit on the abutment plate unit.
