Abstract: A system uses GPS receivers and other sensors to acquire data about one or more objects at an event. The data acquired by the GPS receivers and the sensors is used to determine various statistics about the objects and/or enhance a video presentation of the objects. In one embodiment, the acquired data is used to determine three dimensional positions of the objects, determine the positions of images of the objects in a video and enhance the video accordingly. One exemplar use of the present invention is with a system for tracking automobiles at a race. The system determines statistics about the automobiles and enhances a video presentation of the race.

Abstract: The present invention provides systems and methods for providing television schedule and/or listing information to a viewer, and for allowing the viewer to link, search, select and interact with information in a remote database, e.g., a database on the Internet. The television schedule and/or listing information can be displayed on a variety of viewer interfaces, such as television screens, computer monitors, PCTV screens and the like. The television schedule and/or listing information may be stored on the viewer's computer, television, PCTV, or a remote server (e.g., a website), or the television schedule and/or listing information may be downloaded from a remote database to the viewer's computer, television or PCTV.

Abstract: A system is disclosed that can determine the speed of a golf club or golf ball, and report that speed in a format suitable for use on a television broadcast, a radio broadcast, the Internet or another medium. In one embodiment, the system includes a set of radars pointed toward the golf ball. Data from the radars is collected and sent to a computer which can determine the speed of the club during a swing, the speed of the ball after being hit, the angle of the path of the ball and/or other related statistics.

Abstract: A system is disclosed that uses GPS and additional data to determine the location of an object. Typically, GPS receivers need valid data from four satellites to accurately determine a three dimensional location. If a GPS receiver is receiving valid data from fewer than four satellites, then additional data is used to compensate for the shortage of satellites in view of the GPS receiver. Examples of additional data includes a representation of the surface that the object is traveling on, an accurate clock, an odometer, dead reckoning information, pseudolite information, and error correction information from a differential reference receiver. An exemplar use of the disclosed system is to concurrently track a set of one or more automobiles during a race. The determined locations of the automobile can be used to provide route information, to generate statistics and/or to edit video of one or more of the automobiles.

Abstract: An apparatus and method for programming a VCR is provided. The system, utilizing a programming controller, presents a display on the viewer's television which contains a pattern representing a plurality of time intervals. The user programs the controller by indicating what time intervals on what week and on what channel are to be recorded. The controller then continually compares the current time with the programmed time until a match is found. When a match is found the controller activates the VCR, tunes the VCR to the desired channel, and initiates recording. When the controller determines that the VCR has recorded for the desired length of time, it stops the VCR from further recording and turns off the power to the VCR.

Abstract: A system is disclosed that can determine the speed of an object and report that speed in a format suitable for use on a television broadcast, a radio broadcast, the Internet or another medium. One example of a suitable use for the present invention includes determining the speed that a baseball player swings a bat. Another use of the present invention is to measure the speed of a moving ball. In one embodiment, the system includes a set of radars positioned behind and pointed toward the batter. Data from all of the radars is collected and sent to a computer which can determine the start of a pitch, when a ball was hit, the speed of the ball and the speed of the bat.

Abstract: A system and method for displaying a simplified electronic program schedule guide on a user's television monitor is provided. In one embodiment, the program schedule guide is abbreviated to include only the programs currently available for viewing on a subset of the available channels. In another embodiment, the program guide screen visually distinguishes between programs for the convenience of the viewer.

Abstract: A system and method for displaying an electronic program schedule guide is provided. The system has areas for displaying program schedule information. In addition, the system also has areas that may be used for displaying movie listings. The system has enhanced recording capabilities, including extending recording time, automatically rescheduling recording, and the like. Finally, the system has features which simplify the setup and installation procedures.

Abstract: A navigation system comprising a relative positioning system (RPS) with dead reckoning and map matching and an absolute positioning system (APS) is provided and operated in such a manner that APS position information is used for updating RPS position and contour of equal probability (CEP) information as required. The APS may comprise a Loran-C or a global positioning system (GPS). Different criteria are used for resetting the RPS depending on whether or not the navigation system comprises a Loran-C or a GPS due to the different levels of precision of the Loran-C and the GPS. When the RPS is reset or updated, it is updated to the current APS position with its offset, if any. Its contour of equal probability (CEP) may also be adjusted.

Abstract: A computer hardware and software system and method for displaying a map of streets corresponding to an area over which a vehicle may move to assist a driver to navigate, the system displaying the map on a display based on a scale-dependent street prioritization scheme, providing on the display a vehicle position symbol indicating the current position and heading of the vehicle and a moving map which moves in translation and rotation as the vehicle moves, selectively and dynamically labelling streets on the display as the vehicle moves, and providing a destination symbol on the display indicating a desired destination or the direction to a desired destination.

Abstract: A vehicle navigational system and method for tracking a vehicle, including a programmed computer, sensors for sensing the distance traveled and heading of the vehicle, and a stored map data base identifying a map of an area over which the vehicle is moving, in which the computer calculates and advances dead reckoned positions of the vehicle in response to distance and heading data, provides data identifying a contour of equal probability containing the dead reckoned positions and having a probability of containing the actual location of the vehicle, derives multiparameters from the map data base, and updates a given dead reckoned position and the contour using a highly developed vehicle navigational algorithm if a more probable dead reckoned position exists based upon the given dead reckoned position, the contour and the derived multi-parameters.

Abstract: A method and apparatus for measuring relative heading changes in a vehicular onboard navigation system is provided comprising apparatus for providing signals corresponding to differential wheel distance measurements, the velocity and wheel tracking distance of the vehicle. When front wheel distance measurements are used in a vehicle having an Ackerman-type steering system, an apparatus for providing a signal corresponding to an effective front wheel tracking distance as a function of the curvature of turn is also provided.

Abstract: Disclosed is an apparatus generating accurate data regarding the heading of a land vehicle as it travels over terrain having changing conditions. The apparatus includes a first sensor means, such as a differential odometer, generating data regarding the relative direction of the vehicle. Also included is a second sensor means, such as a flux gate compass, for generating data regarding the absolute direction of the vehicle relative to the earth. The relative directional data and the absolute directional data are combined in a means for generating accurate data regarding the heading of the vehicle. A means for reducing errors reflected in signals generated by the sensors is provided to insure the accuracy of the output.
