A glass article having an excellent heat resistance, capable of preventing any of layers disposed on a glass substrate from peeling off or being clacked even after a long period of time has elapsed after the bending thereof at a high temperature is provided. A glass article according to the present invention includes, on a glass substrate, a carbon-added silicon oxide layer, a transparent conductive oxide layer, and a shielding layer in this order, in which an atomic-composition percentage ratio C/Si of carbon to silicon in the carbon-added silicon oxide layer is 0.1 or more and 0.5 or less, and a linear expansion coefficient α.sub.Sh of the shielding layer is 7.7×10.sup.−3/K or less.

A controllable privacy structure, such as a window or door, may include an electrically controllable optically active material connected to a driver. The driver can control the application and/or removal of electrical energy to the optically active material to transition from a scattering state in which visibility through the structure is inhibited to a transparent state in which visibility through the structure is comparatively clear. The driver may need to be located in relatively close physical proximity to the privacy structure the driver is intended to control. Devices, systems, and techniques are described for discretely positioning a driver relative to a privacy structure to be controlled.

A coated glass article includes a glass substrate. A coating is formed on the glass substrate. The coating includes a first coating layer. The first coating layer includes fluorine doped tin oxide. A second coating layer is provided between the glass substrate and the first coating layer. The second coating layer includes silicon dioxide and at least one of phosphorus and boron. The coated glass article exhibits a haze of 2.0% or less.

A material platform with controllable emissivity and fabrication methods are provided that permit the manipulation of thermal radiation detection and IR signal modulation and can be adapted to a variety of uses including infrared camouflage, thermal IR decoys, thermo-reflectance imaging and IR signal modulation. The platform is a multilayer W.sub.xV.sub.1-xO.sub.2 film with different W doping levels (x values) and layer thicknesses, forming a graded W-doped construct. In WVO.sub.2 films with a total thickness <100 nm, the graded doping of W spreads the originally sharp metal-insulator phase transition (MIT) to a broad temperature range, greatly expanding the temperature window for emissivity modulation.

A transparent substrate provided with a multilayer film includes: a transparent substrate having two main surfaces; and a multilayer film obtained by laminating a metal oxide layer and a silicon oxide layer in order on at least one of the main surfaces of the transparent substrate. SiO.sub.x in at least one silicon oxide layer in the multilayer film satisfies a relationship 1.55≤x<2.00. The multilayer film has a luminous transmittance of 20% to 89% and a resistance value of 10.sup.4 Ω/sq or higher. x in SiO.sub.x is a value determined by depth direction composition analysis in X-ray photoelectron spectroscopy (XPS) using argon ion sputtering. When the silicon oxide layer is an outermost layer, the value of x is determined excluding a point where a sputtering time is 0 minute.

A process that anneals a surface of a substrate bearing a coating includes running the substrate under a flash lamp emitting intense pulsed light and irradiating the coating with the pulsed light through a mask located between the flash lamp and the coating. A frequency of the flash lamp and a run speed of the substrate are adjusted so that each point of the coating to be annealed receives at least one light pulse. A distance between a lower face of the mask and the surface of the coating to be annealed is at most equal to 1 mm. A shape and extent of a slit in the mask are such that the mask occults the coating to be annealed in all zones where the light intensity that, in an absence of the mask, would arrive at the coating to be annealed is lower than a threshold light intensity.

A microwave oven (2) with a full glass door (12) for preventing microwave leakage from the cooking cavity (6) of the microwave oven (2) is provided. The front plate (8) of the cooking cavity (6) has a conductive material (10), such as a rubber with conductive filler. The inner glass surface (16) of the door (12) has a conductive coating that creates a ground loop with the conductive material (10) on the front plate (8) of the cooking cavity (6) to prevent microwave leakage from the cooking cavity (6).

A low emissivity coating 30 includes a plurality of phase adjustment layers 40, 50, 62; a first metal functional layer 46; and a second metal functional layer 58 located over and spaced from the first metal functional layer 48. A ratio of the geometric thickness of the first metal functional layer divided by the geometric thickness of the second metal functional layer is in the range of 0.6 to 1. The low emissivity coating 30 provides a reference IGU summer/day SHGC of at least 0.4 and a reference IGU winter/night U factor of no greater than 0.4 BTU/hr-ft-° F. (2.27 W/m2-K).
