Apparatus and method for sanitizing headsets during a period of non-use by placing the headsets on a support construct in the form of a rack within which there is a source of ultraviolet radiation. The headsets are mounted straddling the rack, resiliently gripping the rack to be secured in place, and the rack with mounted headsets is enclosed within a case. The source is activated to pass ultraviolet radiation through the rack to impinge upon the headsets, during a timed duration of operation, with the case automatically locked closed for that duration, thereby sanitizing the headsets. Reflective surfaces within the case serve effectively to immerse the headsets within ultraviolet radiation for the duration of operation, and air is circulated within the case, passing through the rack, during the sanitizing operation to assure complete sanitization of the headsets.

A method for sanitizing headsets during a period of non-use by placing the headsets on a support construct in the form of a rack within which there is a source of ultraviolet radiation. The headsets are mounted straddling the rack, gripping the rack to be secured in place with a resilient biasing force. Then, the rack, with mounted headsets, is enclosed within a case, suitable for storage or transport. The source is activated to pass ultraviolet radiation through the rack to impinge upon the headsets, during a timed duration of operation, with the case automatically locked closed for that duration, thereby sanitizing the headsets. Reflective surfaces within the case serve effectively to immerse the headsets within ultraviolet radiation for the duration of operation, and air is circulated within the case, passing through the rack, during the sanitizing operation to assure complete sanitizing of the headsets.

A portable overhead projector comprising a rigid housing, a collapsible expansion housing, a fold mirror, a fresnel lens, a light source and a projecting head assembly. In the portable configuration of the projector, all of the operational elements of the projector are collapsed into the confines of the rigid housing. The expansion housing is a box-like assembly having two fixed and two hinged sidewalls. The first and second sidewalls are integrally formed with a bottom wall of the expansion housing. The bottom edges of the third and fourth sidewalls are attached via hinges to opposite marginal edges of the bottom wall. The top edges of the third and fourth walls are attached to the underside of the rigid housing by two hinges. The fold mirror is mounted via a hinge to the inner surface of the bottom wall. The projection head assembly which includes a projecting lens and a projection mirror is attached to the rigid housing by a post, a rack and pinion gear mechanism and a mounting arm.
