摘要： The present invention relates to a spill resistant keyboard including at least one conduit to permit a spilled liquid to drain through the keyboard without damaging the keyboard's electronics. The conduit is positioned along a sloped surface located along a front edge of a recessed area of the keyboard to promote the drainage of the spilled liquid through the conduit. The keyboard also includes water protection walls positioned around certain elongated keys prevent the spilled liquid from entering the body of the keyboard.

摘要： An apparatus for a hinged key switch is presented which operates around a hinged pivot point located external to the four points of the key cap, and which comprises a rubber spring providing a vertical bias and an arm with an extension which acts as a stopper when it abuts a raised portion of the mounting plate. The rubber spring is integrally formed from a rubber sheet which is supported on one side by the mounting plate and on the other by the back plate. The stopper extends vertically downward from the key cap and acts to limit the movement of the key in the vertical direction. A horizontal extension from a lower portion of the key cap further extends downward and through a slot in the mounting plate and has a hook which abuts an underside of the mounting plate, such extension from the key cap acting as the pivot point around which the key rotates.

摘要： A wake-up system for an input device having a circuit board inside it has a motion sensor mounted on the printed circuit board inside the input device. The motion sensor has a motion signal output and the wake-up system further include a detection circuit connected to the motion signal output. The detection circuit has a wake-up signal output. The input device can be an optical wireless mouse. The motion sensor may be a mechanical motion sensor such as a tilt sensor having a ball contact and stationary contacts. The stationary contacts may be printed directly on the printed circuit board. The ball contact and stationary contacts form an electrical switch and are gold-plated. The ball contact is conductive. The motion sensor may be sealed to avoid corrosion. The detection circuit detects a change of state of whether the electrical switch formed by the ball contact and stationary contact is opened or closed. A first embodiment can amplify the motion signal from the motion sensor and a second embodiment can detect a low signal from the motion sensor. Also disclosed is a method of waking up an input device such as a mouse and an input device comprising the wake-up system.
