Patent number: 11903102Abstract: The technology relates to keeping sensors of a perception system optically clear and free from condensation. A transparent film, such as Indium Tin Oxide (ITO), acts as a moisture sensor that covers the optical area of interest. When a measured value of the moisture sensor meets a certain threshold that indicates the presence of condensate, power is applied to the sensor, turning it into a heater. When the measured value no longer meets the threshold, power is removed and heating ceases. The ITO layer may be lithographically applied to a glass sensor cover or other window, with interleaved sections of material that are spaced closely to detect a minimum amount of condensate. This arrangement enables the system to be employed in sensor assemblies at various locations along a self-driving vehicle, and can be used with different types of sensors such as lidar sensors, cameras and other imaging devices.Type: GrantFiled: November 30, 2020Date of Patent: February 13, 2024Assignee: Waymo LLCInventors: Noah Lassar, Yiwei Wang

Patent number: 7338149Abstract: The described embodiments relate to methods and systems for forming and protecting electrical interconnect assemblies. In one embodiment, an electrical interconnect assembly forming method forms an electrical interconnect between one or more conductors of a first support structure and one or more conductors of a second support structure. The method also distributes a generally flowable material over the electrical interconnect and exposes the generally flowable material to conditions sufficient to render the generally flowable material into a generally non-flowable state that provides fluid protection to the electrical interconnect and supports the electrical interconnect to reduce stress concentration at the electrical interconnect.Type: GrantFiled: June 24, 2005Date of Patent: March 4, 2008Assignee: Hewlett-Packard Development Company, L.P.Inventors: Mohammad Akhavain, Joseph E. Scheffelin, Noah Lassar, Conrad Lepe
