CPC Code(s): B60W60/00274
Abstract: methods, systems, and apparatus, including computer programs encoded on computer storage media, for computing enhanced surprise metrics for autonomously driven vehicles. one of the methods includes receiving data representing a predicted state of an agent at a particular time, data representing an actual state of the agent for the particular time, and computing a surprise metric for the actual state of the agent based on a measure of the residual information between the predicted state of the agent and the actual state of the agent.

IPC Code(s): G01S17/95, G01S7/487, G01S17/42
CPC Code(s): G01S17/95
Abstract: example embodiments relate to differential methods for determining environment estimation, lidar impairment detection, and filtering. an example embodiment includes dividing a plurality of lidar device channels into a first group and a second group and interleaving the channels. the embodiment includes applying a threshold to the first group. the embodiment further includes emitting light pulses from a lidar device into an environment surrounding the lidar device, and detecting return light pulses. the return light pulses in the first group of channels are sampled from the signals that exceed the threshold. the embodiment may further include determining a differential in a statistical distribution between the return light pulses in the first group and the return light pulses in the second group. based on the differential, the method can include detecting an atmospheric scattering medium in the environment surrounding the lidar device.
20240205054.Low-Speed Ring with Controlled Jitter_simplified_abstract_(waymo llc)

IPC Code(s): H04L25/02
CPC Code(s): H04L25/0292
Abstract: example embodiments relate to communication links, computing systems, and methods for their use. an example embodiment includes a communication link. the communication link includes a low-voltage differential signaling (lvds) driver. the lvds driver is configured to provide a differential signal that is based on a digital bit stream. the digital bit stream includes a series of digital bits that are temporally arranged based on a nominal bit period. the communication link also includes a controllable delay device. the controllable delay device is configured to provide a delay signal to the lvds driver so as to cause a rising edge or a falling edge of respective digital bits to vary in time with respect to the nominal bit period based on a predetermined sequence of delay amounts. the delay amounts represent positive and negative differences in time from the nominal bit period.
