Patent Applications by Waymo LLC
Inventor(s): Nicholas Armstrong-Crews of Mountain View CA (US) for waymo llc
IPC Code(s): G01S13/89, G01S13/931
CPC Code(s): G01S13/89
Abstract: example embodiments relate to self-reflection filtering techniques within radar data. a computing device may use radar data to determine a first radar representation that conveys information about surfaces in a vehicle's environment. the computing device may use a predefined model to generate a second radar representation that assigns predicted self-reflection values to respective locations of the environment based on the information about the surfaces conveyed by the first radar representation. the predefined model can enable a predefined self-reflection value to be assigned to a first location based on information about a surface positioned at a second location and a relationship between the first location and the second location. the computing device may then modify the first radar representation based on the predicted self-reflection values in the second radar representation and provide instructions to a control system of the vehicle based on modifying the first radar representation.
20250061702. Railroad Light Detection_simplified_abstract_(waymo llc)
Inventor(s): Edward Hsiao of Sunnyvale CA (US) for waymo llc
IPC Code(s): G06V10/82, G06N3/08, G06N5/046, G06N20/00, G06V10/764, G06V20/58
CPC Code(s): G06V10/82
Abstract: the technology relates to controlling a vehicle based on a railroad light's activation status. in one example, one or more processors receive images of a railroad light. the one or more processors determine, based on the images of the railroad light, the illumination status of a pair of lights of the railroad light over a period of time as the vehicle approaches the railroad light. the one or more processors determine based on the illumination status of the pair of lights, a confidence level, wherein the confidence level indicates the likelihood the railroad light is active. the vehicle is controlled as it approaches the railroad light based on the confidence level.
20250061806. Application Monologue for Self-Driving Vehicles_simplified_abstract_(waymo llc)
Inventor(s): Salil Pandit of Palo Alto CA (US) for waymo llc, Nirmal Patel of Sunnyvale CA (US) for waymo llc, Renaud-Roland Hubert of Gilroy CA (US) for waymo llc, Maria Moon of Mountain View CA (US) for waymo llc, Lauren Schwendimann of Burlingame CA (US) for waymo llc, Guilherme Villar of San Francisco CA (US) for waymo llc, Ryan Powell of San Francisco CA (US) for waymo llc, Peter Crandall of San Jose CA (US) for waymo llc, Matthew Corey Hall of Cupertino CA (US) for waymo llc
IPC Code(s): G08G1/123, G06Q50/40, H04W4/40
CPC Code(s): G08G1/123
Abstract: the technology includes communicating the current status of a self-driving vehicle to users, such as passengers within the vehicle and other users awaiting pickup. certain information about the trip and vehicle status is communicated depending on where the passenger is sitting within the vehicle or where the person awaiting pickup is located outside the vehicle. this includes disseminating the “monologue” of a vehicle operating in an autonomous driving mode to a user via an app on the user's device (e.g., mobile phone, tablet or laptop pc, wearable, or other computing device) and/or an in-vehicle user interface. the monologue includes current status information regarding driving decisions and related operations or actions. this alerts the user as to why the vehicle is taking (or not taking) a certain action, which reduces confusion and allows the user to focus on other matters.
20250063242. Flexure Amplified Piezo Actuator for Focus Adjustment_simplified_abstract_(waymo llc)
Inventor(s): Shashank Sharma of San Francisco CA (US) for waymo llc
IPC Code(s): H04N23/54, H02N2/04
CPC Code(s): H04N23/54
Abstract: a camera includes a camera focus adjustment device, a lens, and an image sensor coupled to the camera focus adjustment device. the camera focus adjustment device includes a flexure structure. the flexure structure includes an outer framework of structural members continuously interconnected by flexure notch hinges. the flexure structure also includes two inner structural members oriented in parallel and extending from the outer framework of structural members. a gap is between the two inner structural members. the camera focus adjustment device also includes a piezoelectric material within the gap and a pair of wedges within the gap. the pair of wedges is affixed to the piezoelectric material and to one inner structural member of the two inner structural members. based on temperature-based piezoelectric activity associated with the piezoelectric material, the camera focus adjustment device is operable to move the image sensor relative to the lens.
