摘要:
A method for forming a pressure sensor is provided wherein an optical fibre is provided, the optical fibre comprising a core, a cladding surrounding the core, and a birefringence structure for inducing birefringence in the core. The birefringence structure comprises first and second holes enclosed within the cladding and extending parallel to the core. A portion of the optical fibre comprising the core and the birefringence structure is encased within a chamber, wherein the chamber is defined by a housing comprising a pressure transfer element for equalising pressure between the inside and the outside of the housing. An optical sensor is provided along the core of the optical fibre. Providing the optical sensor comprises optically inducing stress in the core so that the optical sensor exhibits intrinsic birefringence. The chamber is filled with a substantially non-compressible fluid. Consequently, the birefringence structure is shaped so as to convert an external pressure provided by the non-compressible fluid within the chamber to an anisotropic stress in the optical sensor.

A low-E coating supported by a glass substrate, the coating from the glass substrate outwardly including at least the following layers: a dielectric layer of or including silicon nitride; a high index layer having a refractive index of at least 2.1; another dielectric layer of or including silicon nitride; a layer comprising zinc oxide; an infrared (IR) reflecting layer, wherein the coating includes only one IR reflecting layer; and an overcoat including (i) a layer comprising tin oxide and (ii) a layer comprising silicon nitride located over and contacting the layer comprising tin oxide. An IG unit including the coating may have a visible transmission of at least 70%.

Example embodiments of this invention relate to a coated article including an infrared (IR) reflecting layer of a material such as silver or the like, for use in an insulating glass (IG) window unit for example. In certain example embodiments, the coating is a single-silver type coating, and includes an overcoat including an uppermost layer of or including silicon nitride and a layer of or including tin oxide immediately under and contacting the silicon nitride based overcoat. In certain example embodiments, the thicknesses of the silicon nitride based overcoat and the tin oxide based layer are balanced (e.g., substantially equal, or equal plus/minus about 10%). It has surprisingly been found that such balancing results in an improvement in thermal cycling performance and improved mechanical durability. In certain example embodiments, the coating may realize surprisingly good substantially neutral film side reflective coloration, and may achieve an improved visible transmission, SHGC ratio and low U-values. Moreover, in certain example embodiments, stress in the overcoat of the coating may be reduced by reducing nitrogen gas flow (N2 ml/kW) and cathode power during a sputter-deposition process, thereby further improving thermal cycling performance.

摘要:
A method of making a coated article (e.g., window unit), and corresponding coated article are provided. A layer of or including diamond-like carbon (DLC) is formed on a glass substrate. Then, a protective layer is formed on the substrate over the DLC inclusive layer. During heat treatment (HT), the protective layer prevents the DLC inclusive layer from significantly burning off. Thereafter, the resulting coated glass substrate may be used as desired, it having been HT and including the protective DLC inclusive layer.
