A power tool includes a housing, a battery coupled to the housing, and a battery cover which covers at least a portion of the battery. The battery cover includes an expandable portion. The expandable portion is moveable from a collapsed position to an expanded position. When the expandable portion is in the collapsed position, the battery cover has a first internal area. When the expandable portion is in the expanded position the battery cover has a second internal area. The first internal area is less than the second internal area.

Some embodiments relate to a method for performing a battery power-based control of an in-call experience based on shared battery power information. Some embodiments relate to a coating of a headset that has a first emissivity over an ultraviolet band and a near-infrared band, a second emissivity over a visible band, and a third emissivity over a mid-to-far infrared band. Some embodiments relate to an aggregate coating of a headset. A thin films is applied to a surface of the headset, and a paint coating is applied to a surface of the thin film to form the aggregate coating. Some embodiments relate to a method for a high-definition multimedia interface derived network timing for distributed audio-video synchronization. Some embodiments relate to a battery containment structure with a metal chassis having surfaces coated with electrical insulators configured to receive a battery, and a lid coupled to the metal chassis.

An energy storage device for a motor vehicle, wherein the energy storage device has a battery module with a battery cell, which has an opening on the upper side thereof, it being possible to release said opening when there is overpressure, and a battery housing, wherein the battery module is arranged with its lower side facing a housing base, wherein the battery housing has a housing cover made of a first material, which can be arranged on a housing lower part of the battery housing, and which has an inner side, which is facing the at least one battery module when the housing cover is in the state in which it is arranged on the housing lower part.
