Patent number: 11912292Abstract: The technology relates to partially redundant equipment architectures for vehicles able to operate in an autonomous driving mode. Aspects of the technology employ fallback configurations, such as two or more fallback sensor configurations that provide some minimum amount of field of view (FOV) around the vehicle. For instance, different sensor arrangements are logically associated with different operating domains of the vehicle. Fallback configurations for computing resources and/or power resources are also provided. Each fallback configuration may have different reasons for being triggered, and may result in different types of fallback modes of operation. Triggering conditions may relate, e.g., to a type of failure, fault or other reduction in component capability, the current driving mode, environmental conditions in the vicinity of vehicle or along a planned route, or other factors.Type: GrantFiled: November 22, 2021Date of Patent: February 27, 2024Assignee: Waymo LLCInventors: Emily Chi, Ryan Joseph Andrade, Andreas Wendel, Michael James, Christian Lauterbach, Etai Bruhis, Christopher Kennedy Ludwick, Alexander Zbrozek, Pieter Kapsenberg, Zhuyuan Liu, Daniel Rosenband

Publication number: 20230194676Abstract: An optical receiver includes a plurality of photodetectors, a shared memory, and a pulse calibration processing unit communicatively coupled to the shared memory. The optical receiver also includes a hardware accelerator module configured to accept input waveforms from the plurality of photodetectors and compare an amplitude of the respective input waveforms with a predetermined threshold. Based on the comparison, the hardware accelerator module could determine subsets of the input waveforms and determine information indicative of characteristic aspects of the subsets of the input waveforms. The optical receiver is additionally operable to store the determined information in the shared memory and trigger an interrupt for the pulse calibration processing unit to initiate a pulse calibration process on the determined information.Type: ApplicationFiled: December 17, 2021Publication date: June 22, 2023Inventors: Pieter Kapsenberg, Georges Goetz

Publication number: 20230184910Abstract: Example embodiments relate to a lower power linearization of lidar signals. An example embodiment includes a method that includes receiving a sample value output by an analog-to-digital converter (ADC) in a processing unit of a lidar system. The ADC may be configured to digitize an optical signal that is compressed by a gain amplifier. The compression may be based on a transfer function comprising one or more linear portions. The method also includes comparing the sample value to one or more threshold values. The one or more threshold values may correspond respectively to the one or more linear portions. The method further includes selecting, for the sample value and based on the comparing, an inverse gain and an associated intercept. The method additionally includes linearizing the sample value based on the selected inverse gain and the associated intercept.Type: ApplicationFiled: December 15, 2021Publication date: June 15, 2023Inventors: Sabareeshkumar Ravikumar, Pieter Kapsenberg, Srikanth Muroor, David Sobel, Michael Dierickx

Patent number: 9799130Abstract: A computer-implemented method includes receiving a spatial feature descriptor representing a binary string of comparison results between specified pairings of N patches in a region of an image, N being an integer greater than one. The method further includes compressing the spatial feature descriptor by determining a minimum number of bits needed to represent N, and generating a sorted array representing a ranking of the N patches based on the binary string of comparison results. Each element of the sorted array is associated with a corresponding patch of the N patches and stores a value representing a ranking of the patch relative to the other N?1 patches and coded using the minimum number of bits needed to represent N. The sorted array may be further compressed using a progressive bit representation decimation process.Type: GrantFiled: October 27, 2015Date of Patent: October 24, 2017Assignee: Google Inc.Inventor: Pieter Kapsenberg
