A system and method for storing data representing a multidimensional entity using corresponding dimensions for the data, storing a further dimension for the data, the further dimension being a modification timestamp indicating a time when the data was modified, receiving a request for the data representing the multi-dimensional entity, the request including a request timestamp indicating a further time when a previous request for the data representing the multi-dimensional entity was received and transmitting the data only when the modification timestamp is later than the request timestamp.

Method and system for caching real-time data

A system and method for storing a plurality data points, each data point representing a geographic location, a first set of data points representing a first geometric object and a second set of data points representing a second geometric object. The system and method then remove a first data point from the first set of data points representing the first geometric object based on at least a distance between a first location represented by the first data point and a second location represented by a second data point of the second set of data points representing a second geometric object.

Proximity-based detail reduction of geographic data

A method to install software by receiving a partially linked version of the software including a plurality of code modules, randomly ordering the code modules, assigning non-volatile memory addresses for the software and generating an executable image of the software. A system to install a software application having a partially linked object code version of the software application including a plurality of code modules and an installation program configured to randomly order the code modules, assign non-volatile memory addresses for the software, and generate an executable image of the software, wherein the installation program performs the ordering, assigning, and generating on a target computing device that is different from a development computing device that partially linked the software application.

Stochastic method for program security using deferred linking

A rule-based system for improving accuracy of geocoding results is provided including a communications device configured to transmit a query including a textually identified location and a geocoding accuracy module configured to receive the query from the communications device and successively remove constraints from the textually identified location until a match is located. Related methods and computer program products are also provided.

Methods, systems and computer program products for obtaining geographical coordinates from a textually identified location

A method and apparatus for enabling a calling party and a called party to exchange useful information with each other during a call setup process are disclosed. For example, the method receives user metadata from an originating party, and sends the user metadata provided by the originating party by embedding the user metadata in a Session Initiation Protocol (SIP) signaling message during a call setup.

Method and apparatus for providing user metadata exchange during call setup

A system having a processor receiving a copy of a program and modifying the copy to create a modified program and a memory including a memory stack, the modified program being stored in the memory stack, wherein a first image of the memory stack storing the modified program is different from a second image of the memory stack storing the copy of the program.

System and method for program stack security

A system generates a randomized hash value and/or verifies data against a randomized hash value. A hashing circuit can respond to data by randomly selecting a hashing algorithm parameter among a defined set of different hashing algorithm parameters, and by applying a hashing algorithm that uses the selected hashing algorithm parameter to hash the received data to generate a randomized hash value. Another hashing circuit randomly selects a hashing algorithm among a defined set of different hashing algorithms, and applies the selected hashing algorithm to hash the received data to generate a randomized hash value. Another hashing circuit applies a hashing algorithm to hash received data to generate an intermediate hash value that occupies a defined memory space, and randomly selects a partial segment of the hash value from a segment of the defined memory space to generate a randomized hash value.

Computing the Q and the P syndromes, which is needed in RAID 6 systems is effected through use of a single ROM lookup table for the necessary finite field multiplication. In one embodiment, the P and Q syndromes for data that normally arrives with 8-bit words are created by using Galois Field GF(2) arithmetic rather than the conventional GF(2) arithmetic, thereby very significantly reducing the requires size of the lookup table.

Lookup-based Galois field operations

This is a method for use in conducting online and/or proxy-based auctions. This method achieves the best possible price in a timely manner, by more closely simulating the mechanics of a face-to-face auction transaction where bidding is not closed at a preset time but by balancing bid frequency against conducting a timely transaction. The process extends the auction closing time by a geometrically decreasing amount to accommodate bids entered near the end of the auction.

Method and system for dynamically extending the duration of an auction

A plurality of disk drives in a disk drive array are synchronized. A synchronization signal is generated at a master disk drive. The synchronization signal is encoded as a radio frequency signal for transmission over a radio frequency network in communication with the plurality of disk drives. The transmitted radio frequency signal is received at a slave disk drive and decoded to recover the synchronization signal. Rotation of a disk in the slave disk drive is synchronized with rotation of a disk in the master disk drive based on the recovered synchronization signal.

Disk drive array synchronization via short-range RF signaling

A process for evaluating and geocoding of GIS data elements utilizes a plurality of 'locate' tests and a weighting scheme to express the match results as a multidimensional vector. Multiple inputs and data sources, as well as ambiguous and partial input data, are used to generate an output with improved precision by applying a weighting function to each input element and generating a set of test vectors (i.e., in the input data element weighted by the known accuracy of the element/source). A sum of a plurality of tests is then generated as the 'characteristic vector' of the test set. By using two (or more) different sets of tests, two (or more) characteristic vectors are formed. Various well-known algebraic techniques can then be used to evaluate the results of each set of tests and select the &#x201c;best match&#x201d; result.

Geocoding method using multidimensional vector spaces

For each process a stack data structure that includes two stacks, which are joined at their bases, is created. The two stacks include a normal stack, which grows downward, and an inverse stack, which grows upward. Items on the stack data structure are segregated into protected and unprotected classes. Protected items include frame pointers and return addresses, which are stored on the normal stack. Unprotected items are function parameters and local variables. The unprotected items are stored on the inverse stack.
