61 results about "Force protection" patented technology

Force protection (FP) consists of preventive measures taken to mitigate hostile actions against Department of Defense and U.S. Coast Guard personnel (to include family members), resources, facilities, and critical information. The concept of force protection was initially created after the Beirut barrack bombings in Lebanon in 1983. With its Cold War focus toward potential adversaries employing large conventional military forces at the time (e.g., the Soviet Union, etc.), the U.S. military had become complacent and predictable with regard to asymmetric attacks by state and non-state actors employing terrorist and guerilla methodologies. As a result, during what were ostensibly peacekeeping operations by a U.S. Marine Corps landing force ashore in Lebanon in 1983, it allowed two civilian trucks to breach the perimeter of the Marines' cantonment area and detonate their load of explosives as suicide vehicles adjacent to the Marines' billeting areas.

Automatic file accessing mechanical arm with force protection function

An automatic file accessing mechanical arm with a force protection function relates to a file accessing device, belongs to the technical field of robots, and aims at achieving automatic accessing of classified or strictly confidential files. Fingers clamp an electric motor to drive an elliptic wheel to rotate; two driven wheels are arranged at two sides of the elliptic wheel and contact with the elliptic wheel respectively; centers of the two driven wheels are connected together through clamping of springs by the fingers; and the two fingers are adjusted to be close to or away from each other through change of center distance of the two driven wheels. A photoelectric sensor is used for detecting whether files exist in the two fingers, arranged between the two fingers, and mounted on a finger shell. A radio frequency identification device (RFID) reader-writer is arranged on the finger shell and used for reading RFID code carrying body information at spine positions of file boxes, and a tray is arranged under the two fingers in extensible mode and used for supporting the file boxes. The automatic file accessing mechanical arm with the force protection function is simple in structure, accurate to operate and suitable for remote manipulation, and is mainly used for automatic accessing of classified or strictly confidential files.
