Abstract: A keyboard assembly includes a chassis formed with a plurality of cavities, a key unit including a plurality of key modules, and a scanning unit. Each key module is mounted in a respective one of the cavities, and has an individual resonant frequency. The scanning unit emits a detecting signal repeatedly, where a frequency of the detecting signal in each repetition being a different one of a plurality of scanning frequencies. The scanning unit and the key modules are configured such that, for each key module, when the frequency of the detecting signal is one of the scanning frequencies that matches the individual resonant frequency of the key module, the key module reaches electromagnetic resonance and the scanning unit acquires a response signal corresponding to the key module in response to the electromagnetic resonance.

Abstract: A cable head of a cable of a cable fixing assembly includes a joint portion and a lock body. The lock body is disposed on two opposite side surfaces of one end of the joint portion and extends therefrom. A fixing board of a cable fixing assembly includes a joint hole, a no-return block and a hook. The joint hole is formed through the fixing board. The no-return block is formed adjacent to the joint hole and includes a guiding slope and a no-return surface. The hook is disposed on the fixing board to fix conductive stranded wires in the cable body. The joint portion and the lock body are inserted into the joint hole and are rotated by an angle, and the lock body moves on the guiding slope and then is locked by the no-return surface.

Abstract: A remote control device is adapted for communicating with and controlling a portable wireless communication device, and includes a communication module for communicating with the portable wireless communication device, a detecting module for detecting movement of an object, and a control unit electrically coupled to the detecting module and the communication module. The control unit is operable to transmit through the communication module a control signal to the portable wireless communication device so as to control operation of the portable wireless communication device when it is determined that the movement of the object is in a predetermined direction.

Abstract: An electronic game board contains a casing; a display panel in the casing exposed from a top side of the casing; a touch-sensitive module on the top side of the casing against the display panel; and a control device in the casing with a built-in game program. The electronic game board is able to provide multiple board games without acquiring sets of different game boards and game pieces. The electronic game board uses the display panel to present the grid and game pieces of a board game. A player is able to interact with the game board and plays a board game by moving the displayed virtual pieces through the touch-sensitive module. In addition, as the game pieces are actually displayed images, there is no need to worry that any game piece would be missing.

Abstract: An electrostatic discharge protection device is used to protect a component from electrostatic discharge in an electronic device. The electrostatic discharge protection device comprises a metal shell, a ground conductor, and a conductive material. The metal shell is used to cover the component. The ground conductor is used to directly connect the metal shell and a first grounded end. The conductive material is used to connect the ground conductor and a second grounded end in order to achieve double grounded effect.

Abstract: An electric fixture includes a housing having one or more orifices for engaging with conductor members each of which includes a ring member having an opening for engaging with a lead of an electrical wire, the lead of the electrical wire is easily and quickly engaged with the opening of the ring member and secured to the ring member by deforming the ring member for allowing the leads of the electrical wires to be easily and quickly and solidly connected or coupled or secured to the conductor member by the users themselves without special tools or the other mounting machines.
