摘要： A device for detecting the presence of an object is provided. The device includes a light source, a current controller coupled to the light source, a sensor and a pattern detection engine. The current controller sets to provide the light source with a drive current having a pattern. The sensor is operable to receive light, notably light reflected from an object at the detection area and subsequently generates a signal in response to the light received. The pattern detection engine receives the signal from the sensor and subsequently reports the presence of the object upon determining the presence of the pattern in the signal. The object detection system is further configured to provide a navigation operation when an object is detected at the detection area.

摘要： An optical navigation system with a lift detection module is provided for preventing cursor movement if the optical navigation system has been lifted from the navigation surface. The optical navigation system may include an image sensor, a controller and a lift detection module. The lift detection module may be operatively coupled with the image sensor and the controller to selectively report a motion data upon determining a lift by comparing the average of the photosensitive pixel elements with a pixel element threshold value and the surface quality value with a surface quality threshold value. The lift detection module may be incorporated in a microcontroller, wherein the microcontroller may be added to a navigation system to provide an additional lift detection feature.
