Abstract: A specially designed, two section, adjustable belt using an adjustable connection between the sections at the back of the user is described. The adjustable connection allows the weight of a load to be positioned over the hips of a user thereby reducing back strain and discomfort. An adjustable weight-distributing shoulder harness is described with back-crossing straps that are movably secured to each other where they cross by a strap secured to one of the shoulder straps to define an opening that movably receives the other shoulder strap. A load strap is used to secure the load to the belt and uses a position ring for centering the load on the load strap.

Abstract: One or more circuit-breakers (20 and 32) are installed into power pack circuitry 10 to prevent fire and destruction of the power supply 12 and circuits as a result of shorted components. One or more additional circuits 30 allow simultaneous use of more than one device or provide for a backup device should the first circuit fail. The circuit-breaker (20 or 32) permits quick recovery of the circuitry in dangerous situations such as mining or hunting activities. Batteries 12 of a power supply are attached to a specially designed adjustable belt 40 that allows the weight of the power supply to be positioned over the hips of a user thereby reducing back strain and discomfort. The weight of the power pack is further distributed over the user's body by means of a shoulder harness 70.
