Patent number: 9433065Abstract: A lighting system includes a light emitting diode array, and a time of flight ranging system. A logic circuit determines a distance to an object using the time of flight ranging system and controls the light emitting diode array based upon the distance to the object. A receptacle is coupled to the logic circuit, and sized and configured to fit within and be powered from a light bulb socket. In some applications, the logic circuit may activate the light emitting diode array when the object is less than a threshold distance away from the lighting system and deactivate the light emitting diode array when the object is greater than the threshold distance away from the lighting system. In further applications, the logic circuit may activate the light emitting diode array at a duty cycle that varies based upon the distance to the object.Type: GrantFiled: November 5, 2014Date of Patent: August 30, 2016Assignee: STMicroelectronics (Research & Development) LimitedInventor: Jeffrey M.

Patent number: 9417734Abstract: A module operates in a proximity detection mode and a gesture detection mode. The module includes an illumination source, radiation sensors and a controller. When in proximity detection mode, the illumination source emits radiation, the radiation sensors measure the radiation level, and the controller adjusts the measured radiation level to substantially cancel the contribution attributable to ambient radiation to determine the presence of a proximate object by. When in the gesture recognition mode, the level of radiation incident on the sensors is individually sampled, and the controller determines object movement by comparing the changes in the measured radiation levels over a plurality of the samples. Ambient radiation contribution is not removed from the sampled radiation levels during the gesture recognition mode.Type: GrantFiled: July 16, 2013Date of Patent: August 16, 2016Assignee: STMicroelectronics (Research & Development) LimitedInventors: Jeffrey M.
