A video recording device, holster and article of clothing are disclosed to reliably and covertly provide for the capture of video, audio, and metadata, and perform other commands. The holster may be provided with a carrier that is, in turn, inserted into the holster. In one embodiment, the holster may be confirmed as being associated with the video recording device to authenticate a user, and establishes a docked position. Moreover, the video recording device may enter a mode of operation associated with using the video recording apparatus automatically when inserted into a holster.

The exemplary embodiments disclosed herein are directed to a heat exchanger assembly for cooling power module bricks, the heat exchanger assembly having a plurality of spaced apart heat exchanger layers between which external air and a closed loop gas are separately circulated. A series of metallic plates may be located within the spaces between some or all of the heat exchanger layers to conduct heat from the power modules. Circulating fans may be employed to circulate external air and circulating gas through the heat exchanger. Pass through junctions may be positioned near edges of the heat exchanger to permit the circulating gas to cross paths with the external air without allowing the two gas flows to mix with one another.

Provided is an editable read-write data memory based on mechanical structure, including: a storage unit, a signal collection unit and a cantilever unit. The data memory is formed by arranging several storage units, and each of which includes a rotation unit and a variable-frequency unit. An N-pole magnet is provided on the rotation unit, and an S-pole probe is provided on the cantilever unit. When the external environment changes and drives the S-pole probe on the cantilever unit to approach the N-pole magnet on the rotating unit, the rotation unit rotates and drives the variable-frequency unit to buckle, and the change of buckling shape leads to a state change, so as to store data. The signal collection unit is connected with the variable-frequency unit, and the collected electrical signals are display. The stored information in the memory is read according to the change of the output electrical signals.

A disc drive has an opening portion for inserting a disc. The disc drive includes a driving unit, a moving member, a traverse, a disc positioning structure and a restoring structure. When the disc is intended to be clamped on the traverse, the driving unit drives the moving member to move the traverse to a disc holding position to clamp the disc; and the moving member moves the disc positioning structure to a disc release position so that the disc positioning structure does not contact the disc. When the disc is intended to be released from the traverse, the driving unit drives the moving member to move the traverse to a disc unloading position to unload the disc; and the restoring structure moves the disc positioning structure to a disc loading position to support the disc.
