Patent number: 10891850Abstract: Aspects of the disclosure relate to reducing replacing a desiccant cartridge based upon a condensation risk. In one example, first information corresponding to a current dew point within a sensor housing of a sensor and second information identifying temperature data corresponding to a predefined area where the sensor is projected to travel may be received. Based upon the first and second information a condensation risk corresponding to the likelihood of condensation forming within the sensor housing in the event it traveled within the predefined area based upon the current dew point and the temperature data may be determined. Based upon the determined condensation risk, an indication that a desiccant cartridge within the sensor housing should be replaced to reduce the current dew point and the condensation risk may be provided.Type: GrantFiled: March 4, 2020Date of Patent: January 12, 2021Assignee: Waymo LLCInventors: Darren Xinhang Chen, David Gordon Duff, Alexander Norton Meade

Patent number: 9505348Abstract: Aspects of the present disclosure relate to an apparatus providing a first component having a circular opening with an interior chamfered edge and a second component positioned within the circular opening. The apparatus also provides a magnetic feature at a circular bottom surface of the first component, where the magnetic feature provides a magnetic pull force in a first direction to secure the second component within the circular opening. The second component is configured to break away from the circular opening when a contact force to the breakaway component causes a force in a second direction opposite of the first direction and greater than the magnetic pull force.Type: GrantFiled: November 20, 2015Date of Patent: November 29, 2016Assignee: Google Inc.Inventors: Robert Kim, Kenneth Ryan Loo, David Gordon Duff

Publication number: 20150301695Abstract: The technology relates to selecting and displaying images captured at different points in time. As an example, a user of a computing device may view a first street level image as viewed from a particular location and oriented in a particular direction. The user may select other time periods for which similar images are available. Upon selecting a particular time period, a second street level image may be displayed concurrently with the first street level image, wherein the second street level image was captured on or around the selected time period. If the user changes the perspective of the first image an automatic change in perspective of the second image may occur.Type: ApplicationFiled: April 22, 2014Publication date: October 22, 2015Applicant: GOOGLE INC.Inventors: Su Chuin Leong, David Gordon Duff, Jonathan Siegel, Andrew Vytas Kisielius, Aaron Michael Donsbach

Patent number: 9040184Abstract: A battery pack dehumidifier system for controlling the relative humidity within a battery pack enclosure is provided, the dehumidifier system including a desiccant that absorbs/adsorbs water vapor from the battery pack enclosure. The system heats and reactivates the desiccant at predetermined time intervals or when the humidity within the system reaches a preset level, thereby allowing the desiccant to regain its potential for absorbing/adsorbing water vapor.Type: GrantFiled: January 28, 2012Date of Patent: May 26, 2015Assignee: Tesla Motors, Inc.Inventors: David Gordon Duff, Jeffrey C. Weintraub, Gregory Arcenio

Patent number: 8247097Abstract: A method for controlling the relative humidity within a battery pack enclosure is provided in which the volume of air within the battery pack is exposed to a volume of desiccant contained within a desiccant enclosure. The system is configured to heat and reactivate the desiccant at predetermined time intervals or when the humidity within the system reaches a preset level, thereby allowing the desiccant to regain its potential for absorbing/adsorbing water vapor.Type: GrantFiled: January 28, 2012Date of Patent: August 21, 2012Assignee: Tesla Motors, Inc.Inventors: David Gordon Duff, Jeffrey C.
