<heading lvl="0">Abstract of Disclosure</heading> A system and method for accurately locating and tracking the position of a target, such as a tumor or the like, within a body. In one embodiment, the system is a target locating and monitoring system usable with a radiation delivery source that delivers selected doses of radiation to a target in a body. The system includes one or more excitable markers positionable in or near the target, an external excitation source that remotely excites the markers to produce an identifiable signal, and a plurality of sensors spaced apart in a known geometry relative to each other. A computer is coupled to the sensors and configured to use the marker measurements to identify a target isocenter within the target. The computer compares the position of the target isocenter with the location of the machine isocenter. The computer also controls movement of the patient and a patient support device so the target isocenter is co-incident with the machine isocenter before and during radiation therapy.

System and method for identifying speeding violations, comprising determining a current speed and a current location of a vehicle, determining a posted speed limit for the current location from a speed-by-street database, comparing the current speed of the vehicle to the posted speed limit, and evaluating whether the current speed exceeds the posted speed limit. Errors are identified in the speed-by-street database by storing a plurality of speeding violation records, wherein the speeding violation records each include a speeding event location; analyzing the speeding violation records to identify one or more speeding event locations having multiple speeding violations; comparing a posted speed limit at the one or more speeding event locations having multiple speeding violations to corresponding speed limit data in the speed-by-street database; and identifying one or more speed limit entries in the speed-by-street database that do not match the posted speed limit.

System and method for monitoring a vehicle comprising an accelerometer unit capable of monitoring vehicle accelerations, a processor adapted to receive inputs from the accelerometer unit and to compare the vehicle accelerations to predetermined parameters, wherein an attack on the vehicle is identified when one or more vehicle accelerations exceed an attack threshold, and one or more transmitter units adapted to continuously transmit messages upon occurrence of an attack, wherein the messages comprise a vehicle location.

A sports tracking and analysis system includes a RFID tag implanted onto an item associated with a player and at least one RFID tag implanted on a game ball. The tags and reader are arranged to transfer data such as the time and location of player and ball to each other for readers positioned throughout the field. The readers communicate the data to a computer system designed to process the data and generate player performance statistics including real-time measurements of many characteristics and, over time or based on input data, historical performance statistics. A method of tracking and analyzing the performance of a sports game is also included.

A leadless implantable medical device (LIMD) is provided with dual chamber sensing functionality, without leads, despite the fact that the entire device is located in one chamber. In one embodiment, the LIMD senses local activity in the right atrium (RA) and local activity in the right ventricle (RV), even though it is entirely located in the RA. The sensing electrodes enable sensing in different chambers of the heart while reducing cross talk interference and thus provide accurate tracking of myocardial contraction in multiple chambers.

A method and system for detecting and preventing Internet fraud in online transactions by utilizing and analyzing a number of parameters to uniquely identify a computer user and potential fraudulent transaction through predictive modeling. The method and system uses a delta of time between the clock of the computer used by the actual fraudulent use and the potentially fraudulent user and the clock of the server computer in conjunction with personal information and/or non-personal information, preferably the Browser ID.

A management system for a vehicle having a commodity storage region and traveling along a path having a plurality of geographically-distributed commodity replenishing stations, includes a sensor for measuring a level of the commodity in the storage region and providing commodity level data. A global positioning system (GPS) determines a location of the vehicle along the path. A controller stores a record of current geographical locations of the commodity replenishing stations and current commodity prices thereat, and calculates commodity replenishing schedules of the vehicle at the replenishing stations based on an output from each of the GPS and the sensor, and a commodity price at at least some of the replenishing stations.

A system and method for encoding and decoding information by use of radio frequency antennas. The system includes one or more interrogator devices and RFID data tags. The RFID data tags include a plurality of antenna elements which are formed on a substrate or directly on an object. The antenna elements are oriented and have dimensions to provide polarization and phase information, whereby this information represents the encoded information on the RFID tag. The interrogator device scans an area and uses radar imaging technology to create an image of a scanned area. The device receives re-radiated RF signals from the antenna elements on the data tags, whereby the data tags are preferably represented on the image. The re-radiated RF signals preferably include polarization and phase information of each antenna element, whereby the information is utilized using radar signal imaging algorithms to decode the information on the RF data tag.

A method of vehicle control, in which a global target trajectory is tracked by successively calculating an optimum local trajectory in 4D output space to approach the global trajectory and observe vehicle performance limits and surrounding obstacle clearance. A receding horizon framework is proposed which successively updates the optimum local trajectory according to the current state of the vehicle. Processing overheads can be kept to a minimum by calculating performance limits offline, and optimisation is simplified by using a cost function approach.
