Abstract: An apparatus serving as a portable, lockable secure shell that prevents unauthorized physical and electrical signal access to a device enclosed within the shell. The apparatus comprises a case, a lid, a locking mechanism, cooling means, and charging means. When closed, the apparatus provides Faraday cage protection to an enclosed device to block external electronic, electromagnetic, and radio frequency signals from reaching the enclosed device, which preserves data stored in the device in its original form. In addition, the apparatus prevents clandestine access to an electronic device, which creates an obstacle to unauthorized access of information stored on the device.

Abstract: Solutions for improving efficiency of a filter device for use with a machine requiring clean airflow are disclosed. In one embodiment, the filter device includes: a filter housing about an airflow inlet of the machine, wherein the filter housing comprises an air-permeable filter media configured to filter particles from multi-directional airflow moving through a substantial portion of the filter housing into the airflow inlet.
