Abstract: In one example, a portion of a shell includes a shell wall portion that has an interior wall portion and an exterior wall portion located near the interior wall portion. In addition, fluid passageways are disposed between the interior wall portion and the exterior wall portion. One or more of the fluid passageways are defined in part by one or both of the interior wall portion and the exterior wall portion. The fluid passageways form part of heat exchanger that is integrated in the shell.

Abstract: A network-based search system in which queries and information records are qualified by temporal and geographical references, such as those provided by a map-based directory system. Briefly, queries are submitted using text strings together with time tags and location tags. Time tags and location tags refer to the date/time the query was last submitted for a search and the geographical area of interest (defined by ranges of latitude and longitude coordinates), respectively. The information records being searched preferably contain similar time and location tags. However, time and location tags associated with information records refer to the date/time the record was last modified and the origin of the record, respectively. A mechanism is also provided for determining location tags for records that do not include location tags.

Abstract: A method and system are disclosed for a map-based directory service. Users are presented with a map on a computer screen, the map having symbols indicating real-world locations such as buildings, streets, parks, and bodies of water. A close correspondence exists between the map and the real-world. The map further has symbols indicating virtual locations. A virtual location, as the name implies, refers to a location that appears on the map but is not physically present in the real world. In accordance with the present invention, users can locate listings in conjunction with both real and virtual locations related to such listings, and, can connect to the entities associated with those listings once located.
