摘要： A method and apparatus for calculating the surface distance between two geographical locations are described. According to one aspect of the present invention, values are stored in a square look-up table for determining the square of a value. Also, values are stored in a linear to surface distance look-up table for determining the surface distance of a linear value. Cartesian co-ordinates of the two geographic locations and the square look-up table are then used to calculate the square of the linear distance between the two geographical locations and the linear to surface distance look-up table is used to convert the calculated square of the linear distance to a surface distance.

摘要： Example systems and methods of processing a data search request are presented. In one example, a data search request including a plurality of constraints is received. Each of the plurality of constraints is of one of a plurality of constraint types. At least one of the plurality of constraints of a first constraint type is expanded to one or more constraints of at least one other constraint type. A plurality of search definitions is formulated utilizing the plurality of constraints. Each of the plurality of search definitions includes a unique constraint set excluding at least one of the plurality of constraints. A plurality of searches is performed using the plurality of search definitions to generate a plurality of search results. Data item counts corresponding to the search definitions are calculated. The data item counts and the corresponding search definitions are communicated to a client machine.

摘要： A method and a system to configure a query language using an operator dictionary are provided. Dictionary information that corresponds to a first user is generated. The dictionary information includes a first list of compatible query operators and a description of compatible data types that correspond to each operator in the first list of query operators. A search query to search for document information in a database is received from a first user. The database includes an inverted index. Terms of the search query from the first user are determined to be in accordance with the dictionary information that corresponds to the first user. The search query is applied to the inverted index in the database to identify the document information. The document information is sent to the first user.

摘要： Methods and systems to search a data source based on compatibility with an application. The system receives a first query that includes keywords and identifies at least one keyword in the first query as application information. The application information describes a first application. Next the system infers remaining keywords in the first query as item information that describe a first item that is sought on a network-based marketplace. The first item is a part that is compatible with the first application. Next, the system searches a data storage device to identify a first listing on the data storage device as matched. The first listing includes an item for sale on the network-based marketplace and listing item information that matches the item information in the first query. The first listing further includes listing application information that is matched based on the application information.

摘要： A circuit for sampling a digital input signal utilizing an asynchronous strobe signal and a method for such synchronization are disclosed. The circuit includes an input storage element, such as a latch, which stores the input signal upon receipt of a strobe signal. There is a possibility that the input storage element will become temporarily metastable, with the output of the element being indeterminate, should the digital input signal change levels at substantially the time that the strobe signal is received. The subject synchronization circuit includes circuitry which senses when the input storage element is metastable and gating circuitry which produces a synchronized signal after receipt of the strobe signal, provided the input storage element is not metastable. The synchronized signal can then be used to clock the stored input signal.

摘要： Methods and systems to search a data source based on compatibility via a specification are disclosed. The system receives a query from a buyer that includes keywords and identifies at least one keyword in the query as application information. The application information describes a first application. Next, the system infers the other keywords in the query as item information that describes a first part that is sought on a network-based marketplace. The first part is a component of the first application. Next, the system associates the application information with specification identifiers respectively for parts that fit the first application. Next, the system searches the data storage device to identify listings that respectively describe an item for sale on the network-based marketplace, the listings to include listing specification information that matches at least one of the specification identifiers. The listings further include listing item information that matches the item information.
