Abstract: This document describes a thermal-control system that is integrated into a video-recording doorbell. The thermal-control system includes a combination of heat spreaders and materials with high thermal conductivity. The thermal-control system may spread and dissipate energy from a thermal-loading condition effectuated upon the video-recording doorbell to concurrently maintain temperatures of multiple thermal zones on or within the video-recording doorbell at or below prescribed temperature thresholds.

Abstract: This document describes an image-capturing doorbell device. In aspects, the image-capturing doorbell device provides a compact, space-efficient, battery-powered, doorbell camera. The architecture of the image-capturing doorbell device is optimized by concentrating sensors at one end of the device and user input mechanism(s) at the opposing end of the device and including a thin and narrow middle portion between the two opposing ends. The sensors include an image sensor and a PIR sensor mounted to the same PCB for space conservation. A camera lens protrudes from an outer surface of an IR window aligned with IR LEDs to mitigate IR flare. The PIR sensor is aligned with a lens that enhances radial motion detection by implementing two stacked rows of lenslets. The user input mechanism includes a light ring formed via a two-shot molding technique with a button to bond the light ring to the button for enhanced waterproofing.

Abstract: This document describes asymmetric camera sensor positioning for enhanced package detection. In aspects, an electronic doorbell has an image sensor that is rotated to a portrait orientation and vertically shifted relative to a lens of a camera, resulting in asymmetric positioning of the image sensor relative to the lens. The lens projects an image circle onto the image sensor and the image sensor has a sensor detection area having upper corners within the image circle and lower corners outside of the image circle to enable capture of an object located in a lower portion of the image circle and proximate to an edge of the image circle. Then, lens distortion correction is performed on a captured image to provide a final image usable to detect the package, which may be located within the image circle but outside of a conventional sensor detection area.

Abstract: Voice-controlled devices that include one or more speakers for outputting audio. In some instances, the device includes at least one speaker within a cylindrical housing, with the speaker aimed or pointed away from a microphone coupled to the housing. For instance, if the microphone resides at or near the top of the cylindrical housing, then the speaker may point downwards along the longitudinal axis of the housing and away from the microphone. By pointing the speaker away from the microphone, the microphone will receive less sound from the speaker than if the speaker were pointed toward the microphone). Because the voice-controlled device may perform speech recognition on audio signals generated by the microphone, less sound from the speaker represented in the audio signal may result in more accurate speech recognition, and/or a lesser need to perform acoustic echo cancelation (AEC) on the generated audio signals.

Abstract: This document describes a thermal-control system that is integrated into a video-recording doorbell. The thermal-control system includes a combination of heat spreaders and materials with high thermal conductivity. The thermal-control system may spread and dissipate energy from a thermal-loading condition effectuated upon the video-recording doorbell to concurrently maintain temperatures of multiple thermal zones on or within the video-recording doorbell at or below prescribed temperature thresholds.

Abstract: Devices that include light assemblies for providing visual feedback to users that operate the electronic devices. In some instances, the devices comprise voice-controlled devices and, therefore, include one or more microphones for receiving audible commands from the users. After receiving a command, for instance, one such voice-controlled device may cause a corresponding light assembly of the device to illuminate in some predefined manner. This illumination may indicate to the user that device has received the command. In other instances, the devices may illuminate the lighting assembly for an array of other purposes. For instance, one such device may illuminate the corresponding light assembly when powering on or off, playing music, outputting information to a user (e.g., via a speaker or display), or the like.
