Abstract: Location mapping and navigation user interfaces may be generated and presented via mobile computing devices. A mobile device may detect its location and orientation using internal systems, and may capture image data using a device camera. The mobile device also may retrieve map information from a map server corresponding to the current location of the device. Using the image data captured at the device, the current location data, and the corresponding local map information, the mobile device may determine or update a current orientation reading for the device. Location errors and updated location data also may be determined for the device, and a map user interface may be generated and displayed on the mobile device using the updated device orientation and/or location data.

Abstract: A thermal storage apparatus is disclosed. The apparatus uses a group of heat exchange members immersed in a phase change medium to store coolness by freezing the heat exchange medium. The heat exchange members each include tubular passageways to carry a heat transfer fluid through the apparatus to freeze the phase change material during an ice-forming cycle and to be chilled by the solid phase change material during a melt cycle. The heat exchange members each have substantially continuous opposite surfaces to prevent the solid phase change material from forming an annulus encircling the tubular passageways. During the ice-forming cycle, the solid phase change material forms in complementary sheets or volumes so that during the melt cycle the heat transfer fluid does not gain heat near the outlets. The heat exchange members may be made of a lightweight material, such as plastic.

Abstract: This invention relates to a process for the application of organic materials, such as powders, to hot dip or electroplated galvanized metal which provides a finished material with a higher level of corrosion resistance than that obtained from organic coatings on mild or black steel. Because of the natural corrosion protection properties of the zinc cladding of galvanized metal, no additional passivation of the substrate is necessary as is required with existing processes on mild or black steel. Also, the invention relates to the hot dip or electroplated galvanized metal which has been pretreated by the process of this invention prior to application of an organic powder coating. Hot dip or electroplated galvanized metal treated by this process leads to a uniform coating which is virtually impervious to acid, basic and salt solutions, and which will not scratch or flake off on impact.
