Abstract: A battery pack includes a battery, an outer enclosure housing the battery to form a battery pack, and an expandable portion extending from the outer enclosure and allowing the battery pack to expand along an X-axis of the battery pack. The expandable portion includes an inner portion, an outer portion, and a gap portion between the inner portion and the outer portion. The inner portion and the outer portion have a sealing layer to seal off an interior space and the gap portion is devoid of the sealing layer. The sealing layer allows for fluid communication between the gap portion and the interior space when a pressure exerted on the sealing layer exceeds a pressure threshold. The expandable portion includes folds allowing the expandable portion to fold toward the battery pack in an initial folded configuration and expand away from the battery pack in an at least partially unfolded configuration.

Abstract: 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.

Abstract: The present document describes a camera module with electrostatic discharge (ESD) protection. In particular, the camera module includes a lightning rod structure, which guides an ESD current to a safe location (e.g., system ground) when a lens retainer of the camera module is hit by an ESD spark. Due to the impact on camera focus tuning and the risk of audio rub and buzz, the lightning rod structure does not physically touch the lens retainer. As such, a gap separates the lightning rod structure from the lens retainer. When the lens retainer is stressed by an ESD spark, the gap is broken down and a conductive path is established to guide the ESD current to the safe location through the lightning rod structure. In this way, the ESD current flows along a controlled path instead of jumping to arbitrary locations, which protects nearby susceptible circuitry.
