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.

Display products and methods of processing a glass substrate for use as a light guide plate are also provided.

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.

Abstract: This disclosure relates generally to predicting health of an energy asset, and more particularly to methods and systems for predicting erroneous behavior of an energy asset using fourier based clustering technique. 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.

Abstract: The present disclosure relates to a method and a system for monitoring state of food. In one embodiment, the method received data related to parameters associated with food storage conditions including temperature, humidity, defrost duration and defrost stop temperature and determines deviation of the food storage conditions based on the received data. Further, the method determines deviation in temperature and duration period of deviation and notifies a user if the duration period where the food is in danger zone exceeds a predetermined critical threshold duration period. Further, the deviation of defrost duration and humidity is also determined and notified to the user accordingly so that the user may reduce the duration of opening the door of cold-room, and frequency of such opening. Thus, the present disclosure periodically determines the deviation in critical conditions and enables the user to control the operations of the food storage conditions avoiding food wastage.
