Abstract: Disclosed are implementations that include a method for detecting damage in a geographical area, including receiving a first image of the geographical area, captured after occurrence of a damage-causing event in the geographical area, and obtaining a second image of the geographical area, the second image including image data of the geographical area prior to the occurrence of the damage-causing event, with the first and second images containing an overlapping portion comprising one or more common objects. The method also includes obtaining markers for the first and second images, with the markers being geometrical shapes corresponding to objects in the first and second images, and determining damage suffered by an object, from the one or more common objects, based on differences between a first geometrical shape corresponding to the object appearing in the first image and a second geometrical shape corresponding to the object appearing in the second image.

Abstract: Disclosed are devices, systems, apparatus, methods, products, and other implementations, including a method for detecting damage in a geographical area that includes receiving image data for the geographical area, the image data containing data representative of one or more objects, obtaining damage-index data comprising information indicating potential damage affecting the geographical area, and detecting damage to an object, from the one or more objects in the geographical area, based on the received image data for the geographical area and the damage-index data comprising the information indicating the potential damage affecting the geographical area.

Abstract: A method of setting a set point pressure of a back-up supply to supply gaseous product to the pipeline should pipeline pressure fall below the set point pressure. The pipeline and the back-up supply are part of a gas distribution network also having a production facility for supplying the pipeline with the gaseous product at the target pressure for distribution to customers connected to the pipeline. The set point pressure for the back-up gas supply is continuously calculated by calculating a series of pressure drops for each of the customers being fed by the pipeline and then determining required customer site pressures by adding the minimum contracted supply pressure for each of the customers to their respective pressure drops. The maximum required customer site pressure is utilized as the set point pressure for the back-up supply.

Abstract: A filter system for a container comprising a connector, an adjustable tube coupled to the connector and a filter coupled to said adjustable tube. The adjustable tube can be in the form of a corrugated tube or in the form of a telescoping tube. This system can be coupled to either the input or the output of a container.
