    Abstract: A relative position positioning system includes a first apparatus and a second apparatus. Each one of the first and second apparatuses is configured to sense a relative position of the other in an initialization period. In an operation period, each one of the first and second apparatuses is configured to measure its own displacement relative to a plane, transmit its own measured displacement to the other through a wireless transmission unit, and update the relative position of the other according to its own displacement and the displacement received from the other.

    Abstract: There is provided a vehicle safety system including a sensing unit, a processing unit, a control unit and a display unit. The sensing unit is configured to capture an image frame containing an eyeball image from a predetermined distance. The processing unit is configured to calculate a pupil position of the eyeball image in the image frame and generate a drive signal corresponding to the pupil position. The control unit is configured to trigger a vehicle device associated with the pupil position according to the drive signal. The display unit is configured to show information of the vehicle device.

    Abstract: A keyboard has a keyswitch capable of showing its movement depth. The keyswitch includes a substrate, a lifting unit, a multistage positioning component and a keycap. The lifting unit is disposed on the substrate. The multistage positioning component is disposed on the substrate and has a plurality of first actuating portions. The keycap is connected with the lifting unit and adjacent by the multistage positioning component. The keycap has a second actuating portion. The keycap is moved relative to the substrate via the lifting unit, and the second actuating portion can contact against one of the plurality of first actuating portions to generate a feedback signal.

    Abstract: A universal circuit board compatible for a mechanical keyswitch and an optical keyswitch includes a main body, a plurality of conductive terminals and an opening structure. The main body has a first surface and a second surface opposite to each other. The plurality of conductive terminals is disposed on the first surface of the main body. The opening structure is formed on the main body and pierces through the first surface and the second surface. The opening structure can be inserted by an axle body of the mechanical keyswitch or be an optical transmission channel of the optical keyswitch.
