Patent number: 7324261Abstract: A mirror includes an electro-optic mirror subassembly, and a thin-profiled bezel attached around a perimeter of the electrochromic mirror subassembly. The electro-optic mirror subassembly is supported on a carrier by an adheringly bonded heater and foam tape in a laminar arrangement. The bezel may be bonded to an edge of the front surface of the front element of the electro-optic mirror subassembly, and/or may be bonded and/or interlockingly mechanically attached to an edge of the carrier. Alternatively, the bezel can be a strip of paint or thin coating material. The bezel can be molded in place, or can be pre-molded and elastically stretched to permit assembly. In one form, the bezel includes a laterally-extending fin that prevents seeing past the bezel into the inside of a mirror housing. In at least one embodiment, the assembly has no bezel or only a bezel on one edge.Type: GrantFiled: May 6, 2003Date of Patent: January 29, 2008Assignee: Gentex CorporationInventors: William L.

Patent number: 7297951Abstract: A sensor system senses a scene and includes a dual-band imaging infrared detector lying on a beam path, wherein the infrared detector detects infrared images in a first infrared wavelength band and in a second infrared wavelength band; and a two-color cold-shield filter lying on the beam path between the infrared detector and the scene. The cold-shield filter defines a first aperture size for infrared light of the first infrared wavelength band, and a second aperture size larger than the first aperture size for infrared light of the second infrared wavelength band. The first infrared wavelength band has wavelengths less than wavelengths of the second infrared wavelength band.Type: GrantFiled: July 27, 2005Date of Patent: November 20, 2007Assignee: Raytheon CompanyInventors: Chungte W.

Patent number: 7298484Abstract: An imaging sensor system images in two different spectral bands a light beam traveling on a light path from a target. The sensor system includes an imaging sensor operable to image light of the two different spectral bands, a common optics having at least one reflective or refractive optical element, and a wavelength-selective beamsplitter on the light path between the target and the imaging sensor. The wavelength-selective beamsplitter splits the light beam into two subbeams, one subbeam for each of the two different spectral bands, that are respectively incident upon two different locations of the imaging sensor. The imaging sensor may be used to detect buried explosive mines.Type: GrantFiled: February 7, 2005Date of Patent: November 20, 2007Assignee: Raytheon CompanyInventors: Chungte W. Chen, Cheng-Chih Tsai, John S. Anderson

Publication number: 20030020053Abstract: The present invention provides improved electrochromic layers, which comprise polymeric matrices with electrochromic solutions interspersed therein. Varying an electrical potential difference across a layer of the invention results in reversible variation in the transmittance of light across the layer because of electrochemical processes in the electrochromic solution of the layer. The invention further provides electrochromic devices, in which the electrochromic layers of the invention provide reversibly variable transmittance to light, and various apparatus in which the devices of the invention provide light-filtering or light-color modulation. Such apparatus include windows, including those for use inside and on the outside walls of buildings and in sunroofs for automobiles, and variable reflectance mirrors, especially rearview mirrors for automobiles.Type: ApplicationFiled: February 28, 2002Publication date: January 30, 2003Inventors: William L.
