Abstract: A display assembly includes a display screen having a predetermined generally planar area for displaying transmissive data. A light source is provided for generating light of predetermined intensity, and a circular Fresnel lens is disposed between the light source and the display means, the circular Fresnel lens imaging the light source through the display means and onto an opposite side of the display means. A diffuser is disposed between the light source and the display means for diffusing the light. The intensity of the light source is selected to be appropriate for direct human viewing of the transmissive data.

Abstract: A group II-VI compound semiconductor (16) is used as a surface passivator to control recombination of charge carriers at the surface of a group III-V compound semiconductor (12, 14) by a localized heating step. Control of the recombination of the charge carriers is achieved by chemical reaction of the II-VI compound with excess group V element. In particular, a capping layer (16) of laser annealed ZnS is used for passivating a GaAs device (12, 14).

Abstract: An apparatus and method for detecting a magnetic field has been described incorporating a material which switches from an antiferromagnetic order to a ferromagnetic order upon the application of a magnetic field and wherein the material is FeRh, FeRu, FePd or MnPt, a heating element for controlling the temperature of the material and a current source for sensing the change of resistance of the material to determine when the material is ferromagnetically ordered. The invention overcomes the problem of small changes in resistance of magnetoresistive sensors operating in only the ferromagnetic order.
