Abstract: Protective headgear with adjustable strap system and chin guard includes a first strap secured at its opposite ends to opposite sides of the headgear and adapted to extend downwardly therefrom to beneath the jaw of a person wearing the headgear, and a second strap secured at its opposite ends to opposite rear portions of the headgear and adapted to extend forwardly to and in front of the chin of a person wearing the headgear. The first and second straps are connected with first and second coupling members, respectively, at opposite sides of the strap system, connecting the first and second straps together where they intersect. The coupling members are fixed relative to the first strap and are slidable along the second strap, and one of the coupling members includes a quick-disconnect fitting to enable the first strap to be disconnected between its ends to enable the helmet to be quickly and easily applied to and removed from the head of a person using the headgear.

Abstract: A telephone answering machine having solid state storage of an outgoing announcement (OGA) is improved by magnetic tape apparatus 120 for providing backup protection of the OGA in the event of a power failure. Also stored on the magnetic tape is the time duration of the OGA. Analog to digital conversion of the OGA, for storage in Dynamic Random Access Memories 210, 220 and 230, proceeds at a sampling rate that is inversely proportional to the time duration of the OGA to assure that the available memory space is fully utilized.
