Patent number: 11878717Abstract: In an approach to mirage detection by autonomous vehicles, one or more computer processors monitor road conditions of a road on which an autonomous vehicle is traveling. One or more computer processors detect a visual indication of a water accumulation on the road. One or more computer processors determine whether one or more other vehicles are detected on the road ahead of the autonomous vehicle. Responsive to determining the one or more other vehicles are detected, one or more computer processors request information associated with road conditions of the road ahead of the autonomous vehicle from the one or more other vehicles. Based on a response to the request from the one or more other vehicles, one or more computer processors determine the one or more other vehicles did not detect the water accumulation. One or more computer processors determine the visual indication of the water accumulation is a mirage.Type: GrantFiled: January 24, 2022Date of Patent: January 23, 2024Assignee: International Business Machines CorporationInventors: Saraswathi Sailaja Perumalla, Sarbajit K.

Patent number: 11733354Abstract: A LIDAR sensor assembly includes a laser light source to emit laser light, and a light sensor to produce a light signal in response to sensing reflections of the laser light emitted by the laser light source from a reference surface that is fixed in relation to the LIDAR sensor assembly. A controller of the LIDAR sensor assembly can process a plurality of samples of reflected light signals, process the samples to remove erroneous readings, and then provide accurate distance measurement. The system can use low-pass filters, or other components, to filter the plurality of samples to enable the “actual,” or primary, reflected light signal (i.e., light signal reflected off of a surface in an environment external to the sensor assembly, as opposed to extraneous, internal reflections off of lenses or other components or noise) to be identified and an accurate time of flight to be calculated.Type: GrantFiled: February 22, 2021Date of Patent: August 22, 2023Assignee: Zoox, Inc.Inventors: Turhan Karadeniz, Subasingha Shaminda Subasingha, Ravi Sankar Mahankali, Denis Nikitin

Patent number: 11681029Abstract: A time delay of arrival (TDOA) between a time that a light pulse was emitted to a time that a pulse reflected off an object was received at a light sensor may be determined for saturated signals by using an edge of the saturated signal, rather than a peak of the signal, for the TDOA calculation. The edge of the saturated signal may be accurately estimated by fitting a first polynomial curve to data points of the saturated signal, defining an intermediate magnitude threshold based on the polynomial curve, fitting a second polynomial curve to data points near an intersection of the first polynomial curve and the intermediate threshold, and identifying an intersection of the second polynomial curve and the intermediate threshold as the rising edge of the saturated signal.Type: GrantFiled: November 6, 2020Date of Patent: June 20, 2023Assignee: Zoox, Inc.Inventors: Subasingha Shaminda Subasingha, Riley Andrews, Turhan Karadeniz, Ravi Sankar Mahankali
