Abstract: 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.

Abstract: 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.

Abstract: A portable foldable keyboard comprised of two housings, each of which contains a key assembly, and a central hinge. The two housings can be slid together when the keyboard is unfolded and they interlock to form a sturdy keyboard having the standard QWERTY keyswitch layout.

Abstract: A multiple memory card reader is coupled to an information input device. A memory card is inserted in one of a plurality of memory card slots. Information is read from the memory card and transferred to an information input device controller. The information input device controller receives the information and transmits the information to an input/output controller residing within the information input device. The input/output controller receives the information and transmits the information to a computing device.
