Patent number: 9556070Abstract: An insulating glass (IG) window unit includes first and second substrates, and a low-emissivity (low-E) coating supported by one of the substrates. The low-E coating has two silver based infrared (IR) reflecting layers and allows the IG window unit to realize an increased SHGC to U-value ratio, and an increased thickness ratio of an upper silver based layer of the coating to a bottom silver based layer of the coating. The low-E coating is designed to have a low film-side reflectance, so that for example when the low-E coating is used on surface number three of an IG window unit the IG window unit can realize reduced visible reflectance as viewed from the outside of the building on which the IG window unit is mounted or is to be mounted.Type: GrantFiled: March 22, 2016Date of Patent: January 31, 2017Assignee: Guardian Industries Corp.Inventors: Francis Wuillaume, Brent Boyce

Patent number: 9488738Abstract: A light-reflecting material of a radiation detector, which also comprises photo-detecting elements and imaging elements adjacent to the photo-detecting elements, is provided. Typically, epoxy resin is used as the light-reflecting material. A tough, pliable resin may be used for the photo-detecting elements. This has the advantage of reducing thermal stresses inside the radiation detector, thus reducing the risk of delamination due to e.g. temperature shifts. Moreover, the tough, pliable resin preferably also has a low refractive index, which may increase the scattering co-efficient of the resin as compared to epoxy resin, which has a refractive index of 1.58. The layer thickness of a low-refractive index resin may thereby be reduced as compared to the layer thickness of epoxy resin for a given level of optical crosstalk. Preferable resins are silicon resins and resins of thermoplastic fluoropolymers.Type: GrantFiled: October 29, 2008Date of Patent: November 8, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Simha Levene, Naor Wainer
