    摘要: A system and method for power management of an optical mouse. A mechanical displacement sensor associated with the optical mouse is used to detect movement of the optical mouse. When the optical mouse is motionless, a switch within the mechanical displacement sensor sets the optical mouse to a standby state. The standby state conserves power. When motion is detected by the mechanical displacement sensor, the switch powers up the optical mouse into its normal mode of operation.

    摘要: A system and method are disclosed for determining the minimum required processing speed for a quadrature decoder using measurements of an encoder performance, and to assess the safety factor of a particular decoder processing speed. The system and method may also be used to indicate proper adjustment direction by displaying real-time error measurements during encoder alignment. The system measures the logic state width error and provides for calculation of alignment parameters, processing speed and a safety factor. The method allows a measured the logic state width error can be used to for calculating a minimum required processing speed and a safety factor.
