Abstract: A system and method for aligning video images with an underlying visual field are provided. A video camera is coupled with a heads up display, and a computer positions images from the video camera on the heads up display based on the relative orientations of the camera and the display. As the video camera moves with respect to the display, the images are repositioned within the heads up display. The video image, which may, for example, come from a weapon sight, is aligned within the heads up display so that an observer can easily view the camera image without having to shift focus from the larger scene.

Abstract: Multiple location finding equipment (LFE) inputs are used to enhance location information made available to wireless location-based applications. A wireless network utilizes a mobile switching center to route communications between wireless stations, a network platform, and a variety of LFE systems. A Location Finding System (LFS), resident on the network platform, receives location information from the LFEs and provides location information to wireless location based applications. In this regard, the LFS can receive input information at varying time intervals of varying accuracies and in various formats, and can provide standardized outputs to the applications, for example, depending on the needs of the applications. Multiple inputs may also be co-processed for enhanced accuracy. A specification can be used to ensure that location information at least meets certain minimum criteria, such as geographical accuracy, allowable age, acceptable response time, and confidence.

Abstract: A method and apparatus are disclosed for providing subscriber delivered and personalized location-based services. In one embodiment, the invention is implemented in an intelligent wireless network (100). A subscriber initiates the location-based service process by entering a service request using a wireless telephone (102). The request is transmitted to an intelligent network platform (112) via cell site equipment (108) and MSC (110). An application implementing the process that runs on the platform (112) receives subscriber profile information (114), location finding equipment inputs (116) and service information (118) related to the service request. Based on these inputs, the application selects location-based service data that is transmitted to the telephone (102) via a data server (120), the MSC (110) and the cell site equipment.

Abstract: A Clearinghouse is configured to provision subscriber-specific information with respect to subscribers of multiple wireless networks associated with multiple carriers. Application providers can access subscriber-specific information for subscribers of the various networks via a single source, thereby expediting application development and deployment. Moreover, the reach of such wireless service applications can be extended across wireless networks, thereby enhancing application functionality for subscribers. The Clearinghouse can provision the subscriber-specific information in accordance with specific rule sets for each carrier and/or application provider, thereby enabling provision of subscriber-specific information across multiple networks while addressing the privacy and other concerns of individual carriers. For example, in the context of a social networking application, a social network need not be limited in relation to carrier affiliations.

Abstract: A method of providing location-based services for a mobile unit operating in a wireless network including network structures. The method includes receiving an identifier associated with the mobile unit. The method also includes monitoring a location of the mobile unit using the identifier and a network-assisted location finding system to identify a crossing of a service zone boundary by the mobile unit. The service zone boundary is defined by reference to at least one of the network structures. The service zone boundary also corresponds to a geographic zone boundary. The method further includes transmitting service information to a system user in response to the crossing of the service zone boundary.

Abstract: A magnetic coil inductor for use in magnetic stimulators comprises two face-to-face electrically connected windings each having a multiplicity of turns of a respective conductor. Corresponding turns are separated by a gap which typically is of the order of 18 to 20% of the total height of the coil. The magnetic stimulator includes a discharge capacitor and a switch arrangement operable to provide discharge pulses at a selected repetition rate through the inductor, the inductor and the capacitor constituting a resonant circuit of which the resonant frequency is substantially in excess of the repetition rate and is typically between 2 and 6 kHz.

Abstract: A process (400) according to one implementation of the present invention is initiated by receiving (402) a service zone definition for a boundary crossing. The boundary crossings application further receives (404) a monitoring request. For example, a vehicle rental company may enter the MIN/ESN of all mobile units associated with vehicles that are to be monitored, the timeframes during which the vehicles are to be monitored and the specific zones or boundaries with respect to which vehicle movement is to be monitored. Movements of the mobile unit or units of interest can then be monitored by receiving and storing (406) current location information, retrieving (408) prior location information for the mobile unit or units, and using (410) the current and prior location information to determine whether a service zone boundary has been crossed during the intervening time interval.
