摘要： A geographic data relational database and a spatial library of routines that access and analyze spatial data are used to convert an identified location to a set of geographic coordinate pairs. A geocoder engine applies the spatial library routines to the geographic data in the relational database, and based on the identified location and a set of matching rules, produces the set of geographic coordinates. The geographic data may be derived from multiple sources. The rules may specify, for example, that only geographic coordinates corresponding to an exact match of the identified location are to be returned, or that matching of certain attributes may be relaxed. The identified location may be, for example, the intersection of two streets, an address, a postal area code such as a zip code.

摘要翻译： 地理数据关系数据库和访问和分析空间数据的例程的空间库用于将识别的位置转换成一组地理坐标对。 地理编码引擎将空间库例程应用于关系数据库中的地理数据，并且基于所识别的位置和一组匹配规则，产生一组地理坐标。 地理数据可以从多个来源导出。 规则可以指定例如仅返回与所识别的位置的精确匹配相对应的地理坐标，或者可以放宽某些属性的匹配。 识别的位置可以是例如两条街道的交叉点，一个地址，邮政区号等邮政编码。

摘要： An apparatus periodically dispenses an air freshening substance from a pressurized container into a room. A device is provided to sense when the room is occupied, such as by detecting the light level in the room. The air freshening substance is dispensed more frequently when the room is being used than at other times. However, the dispensing continues even when the room is unoccupied to treat odors arising from objects permanently located in the room.

摘要： A system and method for indexing and storing multi-dimensional or multi-attribute data. Data items are recursively sorted in a selected dimension (e.g., the dimension having the greatest variance) and divided until each subdivision fits into a leaf node having a specified fanout. Intermediate nodes and a root node are constructed to complete the index. Each node of the index is stored in a database as a separate object or record and may include a node identifier of the unique, an identifier of a parent and/or a sibling node and an entry for each child of the node, which may be data items or other nodes. Each record entry for a child includes an associated bounding area encompassing descendant data items. Another database table or module may store information about the index, such as the dimensionality of the data, the index fanout and an identifier of a root of the index.
