In one embodiment of the present invention, a military helmet incorporating a neck shield extension is described. The neck shield extension is coupled to the body of the helmet using a plurality of elongated flexible straps. Accordingly, the neck extension moves upwardly whenever the wearer tilts his/her head back or to the side so that the wearer's head mobility is not hindered. The straps are comprised of a material having both a high tensile strength and tensile modulus that helps firmly hold the extension in place relative to the helmet when the extension is impacted with a ballistic projectile or other shrapnel.

A telephone maintenance termination unit utilizes a low voltage, bidirectional trigger switch for performing diagnostic functions on a telephone line. The trigger switch provides low voltage, low current triggering in conjunction with a high holding current requirement. The trigger switch may comprise either two silicon controlled rectifiers connected in inverse parallel relationship with their gates connected, a bidirectional diffused PNPN semiconductor device, or an NPN semiconductor device, any one of which is used to trigger a power control TRIAC. In another embodiment, the switching device may be a two-terminal, unitary semiconductor device incorporating the functions of both the TRIAC and the bidirectional trigger switch.
