  • Publication number: 20240085766
    Abstract: This document describes a thermal-control system that is integrated into a security camera. The thermal-control system includes a combination of heatsinks and thermal interface materials with high thermal conductivities. The thermal-control system may transfer and spread energy from a high thermal-loading condition effectuated upon the security camera to concurrently maintain temperatures of multiple thermal zones on or within the security camera at or below prescribed temperature thresholds.

  • Publication number: 20230384655
    Abstract: This document describes a security camera with an angled cable attachment for an increased downward viewing angle. The security camera is battery-powered and can be magnetically coupled to a mounting device and electrically connected to another device via a cable. The cable has a cable attachment that, when coupled to the security camera, is angled toward a front of the security camera. This cable angle enables an increased downward tilt angle of the security camera by reducing interference of the cable attachment with the mounting device when the security camera is tilted downward. The security camera also has exposed contacts on a printed circuit board that connect with pins on the cable attachment.

  • Publication number: 20230031426
    Abstract: Sensor-based privacy-event detection for a mounted electronic device is described. In aspects, a security system includes a head assembly removably and magnetically coupled to a mounting device having a magnet. The electronic device also includes a camera module and a sensor disposed within the housing. The sensor detects a magnetic field associated with the magnet when the head assembly is coupled to the mounting device. When a user detaches the head assembly from the mounting device (e.g., to recharge the electronic device), the sensor no longer detects the magnetic field and determines the occurrence of a privacy event, which is used to deactivate the camera module to prevent unintentional recordings during the privacy event.

  • Patent number: 10401902
    Abstract: An electronic device including a hollow housing and a display assembly. The hollow housing includes a wall, a circular opening disposed through the wall, and a first attachment mechanism positioned on the housing proximate to the circular opening. The display assembly includes a circular display screen and a display frame coupled to the circular display screen. The display frame is disposed within the circular opening and has a second attachment mechanism disposed proximate a periphery of the display frame to engage the first attachment mechanism and secure the display assembly to the hollow housing.

  • Patent number: 10321588
    Abstract: Systems, methods, and computer-readable media are disclosed for a flexible battery. The systems, methods, and computer-readable media described herein may improve user experiences and prolong the battery's life. In an example embodiment described herein, a flexible battery may comprise a first battery portion positioned in a grip portion and having a first thickness, and a second battery portion positioned in a second portion having a second thickness that is less than the first thickness, wherein the second battery portion is bendable in the at least one direction, and the first battery portion is rigid.

  • Patent number: 9615011
    Abstract: An electronic device includes an elongated tubular housing. One or more electronic components are coupled to a chassis disposed in a cavity of the tubular housing. A pair of elongated channels are positioned on opposite sides of the chassis and between the chassis and a sidewall of the tubular housing. The channels are tapered or wedge-shaped along their lengths. During assembly, one of the channels may be slid longitudinally along the other, causing the channels to expand laterally, due to their wedge shape, to secure the chassis in the tubular housing. The chassis and the pair of channels provide a thermally conductive path to dissipate heat. During use, heat generated by the electronic components is transmitted radially outward from the electronic components, through the chassis and the pair of channels, and through the tubular housing to the exterior of the portable electronic device.
