Patent number: 11774563Abstract: A method of using an optical TOF module to determine distance to an object. The method includes acquiring signals in the TOF module indicative of distance to the object, using a first algorithm to provide an output indicative of the distance to the object based on the acquired signals, using at least one second different algorithm to provide an output indicative of the distance to the object based on the acquired signals, and combining the outputs of the first and at least one second algorithms to obtain an improved estimate of the distance to the object. In some implementations, each of the first and at least one second algorithms further provides an output representing a respective confidence level indicative of how accurately distance to the object has been extracted by the particular algorithm.Type: GrantFiled: November 30, 2018Date of Patent: October 3, 2023Assignee: ams International AGInventors: Stephan Beer, Ioannis Tolios, David Stoppa, Qiang Zhang, Pablo Jesus Trujillo Serrano, Ian Kenneth Mills, Miguel Bruno Vaello Paños, Bryant Hansen, Mitchell Sterling Martin, Doug Nelson

Patent number: 11579291Abstract: An apparatus includes a time-of-flight (TOF) sensor system that has an illuminator operable to emit pulses of light toward an object outside the apparatus. The illuminator is operable in a first mode in which the illuminator emits pulses having a first width and a second mode in which the illuminator emits pulses having a second width longer than the first width. The TOF sensor system further includes a photodetector operable to detect light produced by the illuminator and reflected by the object back toward the apparatus. An electronic control device is operable to control emission of light by the illuminator and is operable to estimate a distance to the object based on a time elapsed between an emission of one or more of the pulses by the illuminator and detection of the reflected light by the photodetector.Type: GrantFiled: December 27, 2018Date of Patent: February 14, 2023Assignee: AMS SENSORS SINGAPORE PTE.
