Patent number: 11858524Abstract: A wind tunnel test may be performed on a vehicle to determine accumulation of substances (e.g., water) on sensors of the vehicle. Control surfaces may be created for the sensors based images representing the accumulations, where the control surfaces represent the include obstructions located where accumulations were detected during the test. The vehicle may then navigate around an environment using the control surfaces in order to determine a drivability of the vehicle. Also, a simulation may be performed, where the simulation outputs images representing simulated accumulations on the sensors. The outputs from the simulation may be compared to the results from the test in order to determine how accurately the simulation represents the test, determine domains in which the vehicle may safely operate, and/or improve the simulation.Type: GrantFiled: April 30, 2020Date of Patent: January 2, 2024Assignee: Zoox, Inc.Inventors: Holly Ho, Christopher William Labadie, Ryan McMichael, Joseph Patrick Warga

Patent number: 11842576Abstract: Techniques for determining a degraded state associated with a sensor are discussed herein. For example, a sensor associated with vehicle may captured data of an environment. A portion of the data may represent a portion of the vehicle. Data associated with a region of interest can be determined based on a calibration associated with the sensor. For example, in the context of image data, image coordinates may be used to determine a region of interest, while in the context of lidar data, a beam and/or azimuth can be used to determine a region of interest. A data metric can be determined for data in the region of interest, and an action can be determined based on the data metric. For example, the action can include cleaning a sensor, scheduling maintenance, reducing a confidence associated with the data, or slowing or stopping the vehicle.Type: GrantFiled: February 3, 2023Date of Patent: December 12, 2023Assignee: ZOOX, INC.Inventors: Christopher David Canady, Ryan McMichael, Irene Perali, Sandra Ruiz

Patent number: 11753003Abstract: A LIDAR system includes a laser emitter configured to emit a laser pulse in a sample direction of a sample area of a scene. A sensor element of the LIDAR system is configured to sense a return pulse, which is a reflection from the sample area corresponding to the emitted laser pulse. The LIDAR system may compare a width of the emitted laser pulse to a width of the return pulse in the time-domain. The comparison of the width of the emitted pulse to the width of the return pulse may be used to determine an orientation or surface normal of the sample area relative to the sample direction. Such a comparison leads to a measurement of the change of pulse width, referred to as pulse broadening or pulse stretching, from the emitted pulse to the return pulse.Type: GrantFiled: February 7, 2020Date of Patent: September 12, 2023Assignee: Zoox, Inc.Inventors: Adam Berger, Ryan McMichael, Bertrand Robert Douillard

Patent number: 11740335Abstract: A machine-learned (ML) model for detecting that depth data (e.g., lidar data, radar data) comprises a false positive attributable to particulate matter, such as dust, steam, smoke, rain, etc. The ML model may be trained based at least in part on simulated depth data generated by a fluid dynamics model and/or by collecting depth data during operation of a device (e.g., an autonomous vehicle. In some examples, an autonomous vehicle may identify depth data that may be associated with particulate matter based at least in part on an outlier region in a thermal image. For example, the outlier region may be associated with steam.Type: GrantFiled: April 16, 2020Date of Patent: August 29, 2023Assignee: Zoox, Inc.Inventors: Sreevatsan Bhaskaran, Mehran Ferdowsi, Ryan McMichael, Subasingha Shaminda Subasingha

Patent number: 11529916Abstract: The described techniques relate to a simulation system that multiplexes sensor data from multiple sensors and outputs the multiplexed sensor data in channels corresponding to the multiple sensors to appropriate vehicle systems at an appropriate time based on encoded timestamp data. In examples, a multiplexer may receive sensor datasets associated with different sensors. The multiplexer may encode the different sensor datasets with timestamp data and supplemental data to generate an encoded dataset. The multiplexer may output the encoded dataset to a video output port to transmit the encoded dataset to a demultiplexer. The demultiplexer receives the encoded dataset from the video output port, and separates the encoded dataset into channels corresponding to the sensors from which the sensor data was received. The demultiplexer may output the datasets in the respective channels at a time (or times) indicated in the timestamp data and according to the supplemental data.Type: GrantFiled: December 27, 2019Date of Patent: December 20, 2022Assignee: Zoox, Inc.Inventors: Turhan Karadeniz, Garen Khanoyan, Ryan McMichael

Patent number: 11500067Abstract: Various lens designs for use in Time of Flight (ToF) sensor systems are discussed. Improvements to a ToF sensor system may be realized by, for example, incorporating a lens having particular features, such as a relatively short track length, fast lens speed (e.g., low f-number), low telecentricity, relatively flat field illumination, and fairly low cost. In some examples, such a lens of a ToF sensor system may be a lens assembly having a fixed focal length and that avoids use of lenses having aspheric surfaces so as to achieve relatively low cost.Type: GrantFiled: November 30, 2018Date of Patent: November 15, 2022Assignee: Zoox, Inc.Inventors: Ryan McMichael, Robert Nicholas Moor, Joseph Patrick Warga, Silas Kogure Wilkinson

Patent number: 11500075Abstract: A LIDAR system that identifies, from a channel output, a false positive return and/or suppressing a corresponding false positive detection caused, in some cases, a strong reflection by a highly reflective surface that caused light to leak from a first channel to a second channel. The LIDAR system described herein may identify, as a false return, a return detected in the second channel that has an intensity that is much less than a return in the first channel and indicates a distance that is the same or very close to a distance indicated the return in the first channel. Based at least in part on identifying a return as a false return, the LIDAR system may suppress a false detection associated with the false return by modifying a detection threshold.Type: GrantFiled: February 14, 2019Date of Patent: November 15, 2022Assignee: Zoox, Inc.Inventors: Sreevatsan Bhaskaran, Mehran Ferdowsi, Ryan McMichael, Subasingha Shaminda Subasingha

Patent number: 11480686Abstract: Particulate matter, such as dust, steam, smoke, rain, etc. may cause one or more sensor types to generate false positive detections. In particular, various depth measurements may be impeded by particulate matter. Identifying a false return and/or removing a false detection based at least in part on a sensor output may comprise determining a similarity of a portion of a return signal to an emitted light pulse or an expected return signal, determining a variance of the signal portion over time, determining a difference between a power spectrum of the return relative to an expected power spectrum, and/or determining that a duration associated with the signal portion meets or exceeds a threshold duration.Type: GrantFiled: April 16, 2020Date of Patent: October 25, 2022Assignee: Zoox, Inc.Inventors: Sreevatsan Bhaskaran, Mehran Ferdowsi, Ryan McMichael, Subasingha Shaminda Subasingha
