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.
摘要翻译：用于其内部具有电路板的输入装置的唤醒系统具有安装在输入装置内的印刷电路板上的运动传感器。运动传感器具有运动信号输出，并且唤醒系统还包括连接到运动信号输出的检测电路。检测电路具有唤醒信号输出。输入设备可以是光无线鼠标。运动传感器可以是机械运动传感器，例如具有球接触件和固定触点的倾斜传感器。固定触点可以直接印刷在印刷电路板上。球接触和固定触点形成电开关并且是镀金的。球接触是导电的。运动传感器可以被密封以避免腐蚀。检测电路检测由球接触和静触点形成的电开关是否打开或闭合的状态的变化。第一实施例可以放大来自运动传感器的运动信号，并且第二实施例可以检测来自运动传感器的低信号。还公开了一种唤醒诸如鼠标的输入设备和包括唤醒系统的输入设备的方法。
