A portable tool kit comprising a self-releasing clasp such that the clasp is released as a main body is rotated about a handle axle from a closed position to an open position with reference to a handle assembly. In a hermetically sealed access pointcomputer, by placing a blowing fan perpendicular to the hot elements of the computer and thereby circulating the air around the housing of the computer the present invention speeds the rate of heat transfer from within the housing to the outside of the housing, thereby reducing the heat that the hardware of a computer has to endure within the housing. In a second embodiment, the isolation mechanism takes the form of a boom extension constructed of or covered with electrically non-conductive material. The structural members define the form of the gunstock, and provide recoil absorption to reduce the amount of recoil experienced by the shooter. A determination is made that the position of the object is not proximate to any position in the collection of positions and an indicator light is generated on the floor proximate to the position of the object.
