Publication number: 20250106489Abstract: The present document describes a video-recording doorbell. In aspects, the video-recording doorbell provides a compact, space-efficient, electronic-doorbell camera device. Thermal control is enhanced by dividing the heat sink into separate sections for different heat-dissipating subassemblies. The video-recording doorbell includes a robust waterproofing system that enables mechanical movement of the button when a user presses the button to initiate a chime event. For an enhanced user experience, the video-recording doorbell also includes a mounting system that is easy to install and provides added security against theft.Type: ApplicationFiled: August 1, 2022Publication date: March 27, 2025Applicant: Google LLCInventors: Alexander P.

Patent number: 12198640Abstract: This application is directed to a method for correct temperature measurement. An electronic device includes a temperature sensor that measures an ambient temperature of an environment and a display that is driven by a display driver. The electronic device determines a brightness setting of the display, estimates a display driver current based on the brightness setting, estimates a driver efficiency of the display driver based on the display driver current, and combines a predetermined display driver voltage, the display driver current, and the driver efficiency to determine a power consumption of the display driver. An ambient temperature correction is determined in accordance with the determined power consumption of the display driver, and the measured ambient temperature is thereby corrected using the ambient temperature correction. In some implementations, a power consumption of a distinct heat-generating electronic component is also monitored for adjusting the ambient temperature correction.Type: GrantFiled: September 20, 2023Date of Patent: January 14, 2025Assignee: Google LLCInventors: Jeffrey Kevin Tu, Kristen Rebecca Pownell, Philip Hobson Boothby, Arun Prakash Raghupathy, Emil Rahim, Chintan Trehan

Publication number: 20240258805Abstract: The present document describes techniques for safe battery charging during high ambient temperatures. These techniques extend device runtime during peak use periods when ambient temperature is high by increasing the possibility for battery charging during high ambient temperature conditions. In an example, a device, during high ambient temperatures, checks future ambient temperatures over a network to identify if the minimum future ambient temperature over a block of time within the next N number of days is predicted to be sufficiently low that, when combined with device-performance throttling, is estimated to reduce the temperature of the battery to below the maximum charge temperature to enable the battery to be safely charged. The device can also use the future ambient temperatures to budget current battery usage by implementing and/or adjusting device-performance throttling.Type: ApplicationFiled: December 14, 2022Publication date: August 1, 2024Applicant: Google LLCInventors: David Wang, Arun Prakash Raghupathy, Chang Hong Ye, Ford Rylander

Patent number: 12001765Abstract: The present document describes techniques associated with a textile-material model for vibroacoustic structural simulation. The techniques described herein provide a nontrivial methodology to test a textile and simplify its representation, which can enable prediction of acoustic performance (e.g., rub and buzz) of an electronic-speaker device having a textile mounted thereon. The textile is modeled as a textile-material model based on an elongation stiffness obtained from a time-temperature superposition curve of the textile, which is based on a dynamic mechanical analysis test of the textile in each of course and wale directions. The textile-material model is then applied to an assembly model of the electronic-speaker device to simulate a vibroacoustic response of the textile relative to the assembly model to predict a likelihood of rub and buzz.Type: GrantFiled: December 15, 2020Date of Patent: June 4, 2024Assignee: Google LLCInventors: Laura Charlotte Shumaker, Arun Prakash Raghupathy, Ayyana Mori Chakravartula, Darren Torrie, Janet P.
