Signaling assembly
First Claim
Patent Images
1. A signaling assembly, comprising:
- a semitransparent mirror formed of a glass substrate having a mirror coating, and wherein the glass substrate substantially absorbs a predetermined band of yellow light, and which further defines a region through which visible light may pass; and
an emitter of visible light positioned adjacent to the semitransparent mirror and which, when energized, emits visible light which passes through the region of the semitransparent mirror which passes visible light to form a visibly discernible signal.

Abstract
A signaling assembly is described and which includes a semitransparent mirror formed of a glass substrate formed of neodymium oxide doped glass and which absorbs, at least in part, a predetermined band of yellow light, and which further defines a region through which visible light may pass; and an emitter of visible light is positioned adjacent to the semitransparent mirror and which, when energized, emits visible light which passes through the region of the semitransparent mirror which passes visible light to form a visibly discernible signal.

33. A signaling assembly, comprising:
-
a semitransparent mirror formed of a dichroic neodymium oxide doped glass substrate having a forward facing, and an opposite rearward facing surface, and a neutrally chromatic reflective layer positioned on the rearward facing surface thereof, and wherein the semitransparent mirror defines a primary region which reflects less than about 20% of a source of visible light having a first portion with wavelengths of about 565 to about 598 nanometers, and a bandwidth of less than about 35 nanometers, and greater than about 50% of a second portion of the visible light having wavelengths which lie within a range of about 400 to about 700 nanometers, and further having a bandwidth of greater than about twice the bandwidth of the first portion of the source of visible light, and which strikes the forward facing surface thereof, and wherein the semitransparent mirror further defines a secondary region, which is adjacent to the primary region, and which passes less than about 20% of the visible light having a wavelength of about 565 to about 598 nanometers, and greater than about 70% of the second portion of the visible light; and an emitter of visible light positioned in light transmitting relation relative to the rearward facing surface of the dichroic neodymium oxide doped glass substrate, and adjacent to the secondary region thereof, and wherein the emitter of visible light, when energized, emits the second portion of the visible light which is passed by the secondary region, and which forms a visibly discernible signal when viewed at a distance from the forward facing surface. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A signaling assembly, comprising:
-
an enclosure defining an aperture; a dichroic neodymium oxide doped semitransparent mirror borne by the enclosure and positioned in substantially occluding relation relative to the aperture, and wherein the dichroic neodymium oxide doped semitransparent mirror reflects and passes a broad band of visible light while simultaneously absorbing, at least in part, a predetermined narrow band of yellow light; and an emitter of visible light borne by the enclosure and emitting visible light within the broad band of visible light which is passed by the dichroic neodymium doped semitransparent mirror. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51)

52. A signaling assembly, comprising:
-
a dichroic semitransparent mirror which absorbs a narrow band of visible light while simultaneously reflecting a broad band of visible light; and an emitter of visible light positioned adjacent to the dichroic semitransparent mirror, and which emits light which is passed by the dichroic semitransparent mirror. - View Dependent Claims (53, 54, 55, 56, 57, 58)
