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： A pointing device such as an optical mouse is equipped with a top surface lift detection system that is able to provide lift detection whether the pointing device sits on a transparent structure or on an opaque structure. The top surface lift detection system relies on the separate detection of a light beam that reflects off the surface upon which the pointing device sits to detect lift whether the pointing devices sits on an opaque surface or a transparent surface.

摘要： An integrated resolution switching surface detection system for an optical navigation device. The integrated resolution switching surface detection system includes a resolution switching engine, a surface detection engine, and a navigation engine. The resolution switching engine sets a resolution status based on a motion speed of a tracking surface relative to a navigation sensor, wherein the motion speed is a measure of motion data over time. The surface detection engine sets a surface detection status based on the resolution status that is set by the resolution engine. The navigation engine reads motion data from the navigation sensor and reports the motion data to a computing device according to the surface detection status that is set by the surface detection engine. Embodiments of the integrated resolution switching surface detection system maintain smooth and predictable cursor movement associated with a plurality of finger assert and finger de-assert events.
