Abstract: A hinged glass article includes wings including glass and a hinge positioned between the wings. The wings fold about the hinge. The hinge includes a glass portion integrally joined to the wings and a polymer portion overlaying the glass portion. The glass portion of the hinge includes a first surface facing away from a second surface thereof. The polymer portion overlays the first surface. The glass portion of the hinge is asymmetric (with the wings unfolded) such that halves of the glass portion of the hinge do not mirror one another about a lengthwise middle of the hinge. Also, the first surface of the glass portion of the hinge is free of small inclusions impinging thereupon that have a linear cross-sectional dimension extending fully thereacross and through a center thereof greater than 2 ?m and less than 30 ?m.

Abstract: Apparatus and method for treating a substrate, for example texturing a substrate. In some embodiments, a masking material is applied to a surface of the substrate in a predetermined pattern, the surface thereafter contacted with an etchant that removes the masking material. Contacting the surface with the etchant produces multiple co-located textures. In other embodiments, the masking step can be eliminated, and the etchant is applied in a predetermined pattern to produce multiple co-located textures. In still other embodiments, the substrate has a chemical composition, and the substrate is exposed to a leachant that leaches at least one constituent of the chemical composition to produce a substrate with a varying chemical composition at the substrate surface.

Abstract: The present disclosure relates to method and device for determining performance of an intermittently used refrigerator. Performance measuring device receives time stamped temperature data from temperature sensor configured in the intermittently used refrigerator. The received time stamped temperature data is used to determine values for each of one or more predefined parameters associated with the intermittently used refrigerator. The performance measuring device determines temperature variation of the intermittently used refrigerator at predefined time intervals. Based on the determined temperature variation, additional service windows in a site comprising the intermittently used refrigerator are identified i.e. the intensity of sales in the site are identified. The determined values of each of the one or more predefined parameters and the determined temperature variation, helps in determining the performance of intermittently used refrigerator.

In one embodiment, a method for determining predicting erroneous behavior of an energy asset is disclosed. The method includes creating one or more energy signatures by performing frequency domain analysis on historical energy data and subsequent clustering of the energy signatures. Further, live energy data is filtered to generate filtered outputs wherein each of the filtered outputs is mapped to a respective cluster. The outlier cluster is identified to predict the erroneous behavior of the energy asset.

Abstract: The present disclosure relates to a method and system for indicating energy savings for a distributed site. The energy savings is indicated by an energy management system, which receives energy consumption data of the distributed site for a first observation period. Further one or more service windows are defined for the distributed site and an energy saving strategy is applied to at least one service window. Further, the energy consumption data for the second observation period is received and a compared of one or more service windows of the first observation period with the corresponding service windows of the second observation period is done. The energy management system further determines adjustment factors in the energy profiles based on parameters affecting the energy profiles which were not considered during the first observation period and hence indicate the energy savings for the distributed site based on the first saving and adjustment factor.
