  • Patent number: 6076948
    Abstract: An electromagnetic radiation emitting assembly is disclosed and which includes a supporting substrate having opposite first and second surfaces and having an area formed therein which allows electromagnetic radiation to pass therethrough; a reflector positioned adjacent to the second surface of the substrate and oriented in a given position relative to the area formed in the substrate; and an electromagnetic radiation emitter mounted on the second surface of the substrate and which emits a source of electromagnetic radiation which is reflected by the reflector through the area formed in the supporting substrate. An electromagnetic radiation receiver is also described.

  • Patent number: 6045243
    Abstract: A mirror assembly including a semitransparent mirror which passes about 1% to about 30% of a broad band of visible light, and which reflects less than about 80% of a broad band of visible light; and a light assembly positioned adjacent to the semitransparent mirror and which emits visible light which is passed by the semitransparent mirror, the luminous intensity of the mirror assembly being about 0.5 to about 120 candelas.

  • Patent number: 6005724
    Abstract: A mirror, mirror coating utilized with same, and mirror assembly are described and wherein the mirror coating has a primary region which reflects visibly discernible electromagnetic radiation, and a secondary region or multiple secondary regions which passes a portion of the visibly discernible electromagnetic radiation while simultaneously reflecting a given percentage of the visibly discernible electromagnetic radiation, and wherein the average reflectance of the entire surface is greater than about 50%.

  • Patent number: 5788357
    Abstract: A mirror assembly including a semitransparent mirror which passes about 1% to about 8% of a broad band of visible light, and which reflects about 35% to about 58% of a broad band of visible light. A light assembly is positioned adjacent to the semitransparent mirror and emits visible light which is passed by the semitransparent mirror. The luminous intensity of the mirror assembly being about 2 to about 20 candelas.

  • Patent number: 5528422
    Abstract: A mirror coating which possesses properties which are advantageous for the construction of a mirror assembly. The mirror coating has a complex reflective index which is wavelength dependent, and wherein the real component is dominant and the imaginary component is negligible within a predetermined spectral band pass region, and the imaginary component is substantially within a spectral region other than the predetermined spectral band pass region, and wherein the mirror coating exhibits substantially neutral reflected chromaticity as observed with reflected ambient light.
