Abstract: A meter has a liquid crystal (20) on which is displayed the value of a metered quantity, for direct visual reading. A single flashing zone (26) is arranged to display a binary-coded representation of the same value as a timed sequence of flashes. The binary 0's and l's are represented by the presence or absence of flashes. 
     The flashing code is read by a photo-electric sensor (22) which transmits electrical signals to remote reading station (24). Thus there are no direct connections to the meter. 
     In an alternative arrangement, fibre optics transmit the flashes of light to a remote station.

Abstract: An automated visual testing system is disclosed which presents an alternating steady state visual stimulus to a patient through an optical system that modifies the stimulus image. As the image changes, the patient produces evoked potentials that change. The evoked potentials are detected (14 + 54 - 58) by a product detector which produces the amplitude of the evoked potentials. A control processor (12) controls a stimulus generator (20) to produce the image and an optical system transmits the image to the patient (22). A supervisor computer (10) produces patient response curves resulting from the evoked potential signals; diagnoses malfunctions in the patient's vision and prescribes correction.

Abstract: A three layer, photovoltaic structure having polycrystalline semiconductor layers disposed in series optically and in sequential touching contact includes a relatively wide optical bandgap energy window layer, a light-absorbing layer and a third, relatively wide bandgap energy layer that forms a minority carrier mirror with the light-absorbing layer. All three layers have different compositions so that the structure includes two heterojunctions. The light-absorbing layer and third layer are of the same conductivity type. The structure is conveniently realized using II-VI semiconductor compounds such as a cadmium sulfide or zinc sulfide window layer, a mercury cadmium telluride, cadmium telluride, zinc cadmium telluride or mercury zinc telluride light-absorbing layer and a third layer of cadmium telluride, zinc telluride, zinc cadmium telluride, mercury cadmium telluride or cadmium manganese telluride. Cadmium is present in at least two of the three layers of the novel structures. Tellurium is present in two of the three layers. Structures according to the invention may be conveniently formed by electrodeposition and may employ opaque or transparent substrates depending on the particular semiconductor materials used and their relative positions.

Abstract: An image reversal process for the production of electrophotographic color proofs from negative separation films where the photoconductive receiving member is reusable and the proofs are produced on printing stock paper and which very closely match the appearance of the printed sheet. The process of the invention comprises, exposing an electrophotoconductor (1) that is charged to a first polarity through a color separation negative film (5) which may be in contact therewith, developing the unexposed areas on the photoconductor with opposite polarity background toner to form background deposits (9) thereon in areas corresponding to the opaque non-image or background areas (6) on the negative (5), subjecting the photoconductor (1) and the background deposits (9) thereon to corona discharge of said first polarity to charge the photoconductor (1) in the areas free of said background deposits (9) that is, in areas corresponding to the transparent image areas (7) on the negative, removing charges of said first polarity from the background deposits (9), developing the image areas on the photoconductor (1) with opposite polarity color toner, and transferring the thus formed color toner deposits (13) to a receptor (14) such as printing stock paper. The process can be repeated for each additional color separation negative film to transfer the additional specific color developed image in proper registry where a proper toner for the specific color image will be used.
