Patent Applications by Waymo LLC
20240271973. Integrated Cooling Solution For Spinning Sensors_simplified_abstract_(waymo llc)
Inventor(s): Simon Ellgas of San Jose CA (US) for waymo llc, Justin Matthew Andrade of San Jose CA (US) for waymo llc
IPC Code(s): G01D11/24, G01S7/481
CPC Code(s): G01D11/245
Abstract: this technology relates to a system for cooling sensor components. the cooling system may include a sensor which has a sensor housing, a motor, a main vent, and a side vent. internal sensor components may be positioned within the sensor housing. the motor may be configured to rotate the sensor housing around an axis. the rotation of the sensor housing may pull air into an interior portion of the sensor housing through the main vent, and the air pulled into the interior portion of the sensor housing may be exhausted out of the interior portion of the sensor housing through the side vent.

IPC Code(s): G08G1/16
CPC Code(s): G08G1/166
Abstract: a method and apparatus are provided for determining whether a driving environment has changed relative to previously stored information about the driving environment. the apparatus may include an autonomous driving computer system configured to detect one or more vehicles in the driving environment, and determine corresponding trajectories for those detected vehicles. the autonomous driving computer system may then compare the determined trajectories to an expected trajectory of a hypothetical vehicle in the driving environment. based on the comparison, the autonomous driving computer system may determine whether the driving environment has changed and/or a probability that the driving environment has changed, relative to the previously stored information about the driving environment.
20240275129. LASER PULSER CIRCUIT WITH TUNABLE TRANSMIT POWER_simplified_abstract_(waymo llc)
Inventor(s): Joshua Jones of Mountain View CA (US) for waymo llc, Augusto Tazzoli of San Jose CA (US) for waymo llc, Pierre-yves Droz of Los Altos CA (US) for waymo llc
IPC Code(s): H01S5/068, G01S7/484, G01S17/10, G01S17/14, H01S5/042, H03K3/017, H03K3/53
CPC Code(s): H01S5/06804
Abstract: a method includes applying, by a switching circuit, pulses of an input voltage to an input of an inductor. the method includes charging, in accordance with an off state of a switch, a charge storage device through the inductor using the pulses of the input voltage such that the circuit node develops a charge voltage that is greater than the input voltage. the method includes discharging, in accordance with an on state of the switch, the charge storage device such that a first portion of the charge voltage is applied to a light emitter and a second portion of the charge voltage is applied to parasitic inductance. the method includes controlling, by a controller, a timing of the pulses of the input voltage applied by the switching circuit based on a parasitic inductance from a previous charging cycle of the charge storage device, so as to control the charge voltage.
