CPC Code(s): B60W60/0016

Abstract: the technology relates to maneuvering a vehicle prior to making a turn from a current lane of the vehicle. as an example, a route that includes making the turn from the lane is identified. an area of the lane prior to the turn having a lane width of at least a predetermined size is also identified. sensor data identifying an object within the lane is received from a perception system of a vehicle. characteristics of the object, including a location of the object relative to the vehicle, are identified from the sensor data. the vehicle is then maneuvered through the area prior to making the turn using the identified characteristics.

20240191715.Air Cooling System for Electronic Spinning Assembly_simplified_abstract_(waymo llc)

Inventor(s): Rutvik Acharya of San Jose CA (US) for waymo llc, Simon Ellgas of San Jose CA (US) for waymo llc, Benjamin Chen of San Francisco CA (US) for waymo llc

Inventor(s): Mark Alexander Shand of Palo Alto CA (US) for waymo llc

IPC Code(s): G01S7/48, G01S7/481, G01S17/10, G01S17/931

CPC Code(s): G01S7/4804

Abstract: example embodiments relate to selective deactivation of light emitters for interference mitigation in light detection and ranging (lidar) devices. an example method includes deactivating one or more light emitters within a lidar device during a firing cycle. the method also includes identifying whether interference is influencing measurements made by the lidar device. identifying whether interference is influencing measurements made by the lidar device includes determining, for each light detector of the lidar device that is associated with the one or more light emitters deactivated during the firing cycle, whether a light signal was detected during the firing cycle.

20240192364.Laser Protection Methods_simplified_abstract_(waymo llc)

Inventor(s): Augusto Tazzoli of San Jose CA (US) for waymo llc

IPC Code(s): G01S17/14, G01S17/26
