To more accurately control insertion of penetrating instruments (e.g., trocars, needles, or the like) into a body cavity, organ, or potential space, an accelerometer is coupled to the penetrating instrument. The accelerometer may by employed to measure or detect the sudden lack of resistance which occurs when the penetrating instrument penetrates to a predetermined depth (e.g., through the abdominal cavity, vein, or outer bone) in a more accurate and reliable way instead of practitioners' subjective feeling. An acceleration sensor (i.e., accelerometer) coupled to the penetrating instrument (e.g., trocar or the like) may transform the physical variable ‘resistance change’ into an electronic signal that is then processed in an electronic circuit, and finally triggers an audible/visible alarm and/or feeds an actuating mechanism to control movement of the penetrating instrument.

A net is made from an explosive resistant material such as KEVLAR and is thrown over an explosive-laden device such that the net helps contain the blast force of the explosive-laden device. The net also has a nozzle that is fluid connected to a fire suppressant agent as well as a high density foam, each of which are discharged through the nozzle once the net is thrown over the explosive-laden device, the fire suppressant agent and the high density foam each helping to minimize the blast force of the explosive-laden device. The net can be thrown manually or can be fired from a gun that uses either pneumatic force or a firing cartridge to propel the net at its target.

A circuit protection device includes a solid-state interrupter that is operable to open a circuit within a specified response time upon detection of a fault current state. A mechanical interrupter is connected in series with the solid-state interrupter. The mechanical interrupter is operable to open the circuit subsequent to the opening operation of the solid-state interrupter. A controller is coupled with the solid-state interrupter and the mechanical interrupter. The controller is operable to detect the fault current state in the circuit and to control the mechanical interrupter for coordinated operation with the solid-state interrupter. In some implementations, the response time is between two microseconds and twenty microseconds. The mechanical circuit breaker can safely physically open the circuit at a low breaking current (e.g., the solid-state interrupter quickly opens the circuit and prevents current from surging to dangerous levels).
