Abstract: A touch control apparatus comprises a capacitive panel and a controller. The capacitive panel comprises a first capacitive sensing area and a second capacitive sensing area. The first capacitive sensing area is used for touch control detection, and the second capacitive sensing area is used for proximity detection rather than the touch control detection. The controller is coupled to the capacitive panel and used for respectively control the first and second capacitive sensing areas to perform the touch control detection and the proximity detection.

Abstract: A distance-measuring device is utilized for measuring a measured distance between a measured object and the distance-measuring device. The distance-measuring device reduces the effect of a background light and a flicking light by removing the part corresponding to the background light and the flicking light from light-sensed signals generated by an image sensor of the distance-measuring device. In addition, the distance-measuring device calculates a calibrating parameter for calibrating an assemble-error angle of the distance-measuring device, according to an imaging location of a reflective light obtained by measuring a calibrating object with a predetermined distance. In this way, the distance-measuring device can correctly calculate out the measured distance.
