Patent number: 12295097Abstract: A planar sensor array, like an imaging sensor array, can be mounted to a ceramic circuit board to provide improved mechanical stability and heat dissipation. Embodiments herein provide improvements to such assemblies by providing two or more recesses in the ceramic circuit board opposite the sensor array. Electronic components can be placed in these recesses, reducing the overall size and moment of inertia of the sensor assembly relative to placement on the same side of the ceramic circuit board as the sensor array. Placing the electronics in the two or more recesses allows for simplified mounting of the assembly to heat sinks, flexible circuit boards, or other elements. The two or more recesses are separated by a stiffening cross-brace portion of the ceramic circuit board that enhances the mechanical strength of the ceramic circuit board.Type: GrantFiled: December 14, 2021Date of Patent: May 6, 2025Assignee: Waymo LLCInventor: Shashank Sharma

Patent number: 12291236Abstract: The technology relates to detection of a nearby occluded object based on illumination emitted from that object. Illumination by the occluded object of one or more areas in the surrounding area, for instance by headlights of an occluded vehicle, is detected by a perception system of a self-driving vehicle. The self-driving vehicle can classify the detected object to determine whether the illumination is caused by a vehicle or other road user, or from objects in the surrounding environment. Illumination data and other information can be evaluated by the self-driving vehicle, for instance to identify a type of the object, a location of the object along a roadway, to disambiguate the direction of travel of the other object, etc. As a result, the self-driving vehicle may infer the behavior of the other object and modify its own driving operations to account for the other object's presence and likely behavior.Type: GrantFiled: November 6, 2020Date of Patent: May 6, 2025Assignee: Waymo LLCInventor: Mehmet Akman

Patent number: 12291200Abstract: The technology relates to determining a future heading of an object. In order to do so, sensor data, including information identifying a bounding box representing an object in a vehicle's environment and locations of sensor data points corresponding to the object, may be received. Based on dimensions of the bounding box, an area corresponding to a wheel of the object may be identified. An orientation of the wheel may then be estimated based on the sensor data points having locations within the area. The estimation may then be used to determine a future heading of the object.Type: GrantFiled: November 16, 2023Date of Patent: May 6, 2025Assignee: Waymo LLCInventor: Jens-Steffen Ralf Gutmann

Patent number: 12280803Abstract: The technology relates to determining a source of a horn honk or other noise in an environment around one or more self-driving vehicles. Aspects of the technology leverage real-time information from a group of self-driving vehicles regarding received acoustical information. The location and pose of each self-driving vehicle in the group, along with the precise arrangement of acoustical sensors on each vehicle, can be used to triangulate or otherwise identify the actual location in the environment for the origin of the horn honk or other sound. Other sensor information, map data, and additional data can be used narrow down or refine the location of a likely noise source. Once the location and source of the noise is known, each self-driving vehicle can use that information to modify current driving operations and/or use it as part of a reinforcement learning approach for future driving situations.Type: GrantFiled: March 18, 2024Date of Patent: April 22, 2025Assignee: Waymo LLCInventor: Nicholas Armstrong-Crews
