Abstract: The energy storage module of the battery pack is located in the housing, the heat insulation panel is located between the energy storage module and the housing, the heat insulation panel includes a heat insulation layer and an outer packaging layer. The outer packaging layer wraps the outside of the heat insulation layer and compresses a thickness of the elastic heat, insulation layer, and a ventilation channel is formed between the heat insulation panel and the energy storage module. The outer packaging layer is configured to release compression of the elastic heat insulation layer when the energy storage module reaches a thermal runaway temperature, and the heat insulation panel is filled between the housing and the energy storage module, thereby slowing down a speed at which heat passes through a side panel and spreads to the outside of the battery pack along the ventilation channel.

Abstract: According to some embodiments, a method includes: receiving, by a computing device associated with a user, a video stream captured by a camera; detecting, by the computing device, persons appearing within a field of view of the camera based on analysis of the video stream; and in response to a determination that one or more persons other than the user appear within the field of view of the camera, providing, by the computing device, a modified video stream in which the one or more persons other than the user do not appear during display of the modified video stream.

Abstract: The present invention relates to an attachment for a phone case that would enable a user of the mobile phone to easily navigate through different portions of the screen, while holding the mobile phone in his/her palm, and enable changing the orientation of the mobile phone relative to a flat surface. The attachment includes an attaching member, a gripping member, a moving arm, a first pin, and a second pin. The attaching member attaches the attachment to the mobile phone case. The moving arm is rotatable about the first pin, and the gripping member is rotatable about the second pin. The mobile phone case includes a protecting base, a side support, openings. The base may be configured to include one or more slots and/or openings for enabling the attachment to attach thereon.

Abstract: A semiconductor-based sensor to detect light angle of incidence includes a semiconductor light sensor element and a patterned spatially inhomogeneous dielectric layer disposed over the semiconductor light sensor element. Characteristically, spatial inhomogeneity of the patterned spatially inhomogeneous dielectric layer is optimized to provide a maximized electric field in the semiconductor light sensor element such that the semiconductor-based sensor is operable to detect one or more incident angles of light at a predefined wavelength or wavelengths of light.
