Abstract: A barrier device is adapted to be worn by a user and provide isolation between the user and an object that is to be contacted by the user. The barrier device comprises a first pocket having a first top surface and a first bottom surface and an opening providing access to a cavity between the first top and bottom surfaces. The barrier device also includes a second pocket having a second top surface and a second bottom surface and an opening providing access to a cavity between the second top and bottom surfaces. A panel interconnects the first bottom surface and the second top surface to connect the first and second pockets, the panel having an adjustable length such that when a user wears the barrier device with one or more fingers in the first pocket and thumb in the second pocket, the panel provides a barrier for the user's palm that is adjustable to accommodate different hand sizes of different users. Furthermore, the barrier device is adapted to be wearable on either the right or left hand of a user.

Abstract: The optical light guide of the present invention is composed of a solid, transparent material selected from the class consisting of glass, acrylic, polystyrene, and polycarbonate. The light guide has a head, a tapered section and a curved section. The head has a light-receiving, concave surface geometry at the proximal end of the light guide.

Abstract: A compact, lightweight source of radiation at wavelengths ranging from long wave ultraviolet through the visible powered from a low power DC source wherein a high frequency oscillator provides regulated driving current for the excitation of a fluorescent tube which emits energy at wavelengths outside the erythemal zone and wherein a first level of energizing current is provided for a warmup of the tube, a second level of energizing current is provided for standby excitation and a third level of energizing current is available for more intense operating excitation during which time there is also provided an audible timing signal.
