Patent number: 12019809Abstract: A method for identifying an object, an optical sensing apparatus and a system are provided. A controller of the system drives multiple light sources of the optical sensing apparatus to emit the multiple light beams with different beam angles, controls a light sensor to sense the lights reflected by the object, and performs the method for identifying the object. In the method, the light sensor is used to sense a first light emitted by a first light source with a first beam angle reflected by the object, and sense an intensity of the reflected first light. The light sensor is also used to sense a second light emitted by a second light source with a second beam angle reflected by the object and sense another intensity of the reflected second light. Therefore, the object can be identified by integrating information of the intensities obtained by the light sensor.Type: GrantFiled: April 10, 2023Date of Patent: June 25, 2024Assignee: PIXART IMAGING INC.Inventors: Tien-Chung Yang, Chia-Kai Chen, En-Feng Hsu, Chen-Lung Liu
