Abstract: A system and method selectively reduce power of an engine having at least one piston movable in a cylinder and an exhaust port includes providing an exhaust valve in communication with the exhaust port of the engine. The exhaust valve has an adjustable position to change an effective size of the exhaust port. The system and method also include sensing a condition likely to cause damage to the piston of the engine and adjusting a position of the exhaust valve to reduce a size of the exhaust port in response to sensing the condition likely to cause damage to the piston of the engine, thereby limiting power of the engine.

Abstract: A technique for estimating the geo-location of a mobile station, based on signal measurements or other data that are obtained from both the control plane and the user plane. Through the coordination of obtaining signal measurements from both planes, the disclosed method and system make location estimations of greater accuracy possible. A data-processing system is configured to receive requests for location estimates from a location-based services (LBS) client or from a different source. The illustrative data-processing system then coordinates the acquisition of location data across both the control plane and the user plane, and correlates the data. The correlated location data can be subsequently used to generate a location estimate.

Abstract: A method and system that account for one or more propagation-time components in a transmission path between a base station and a wireless terminal in a coverage area being served by the system. One such component is in the base station equipment between the radio that serves a wireless terminal and the antenna element that radiates and/or receives electromagnetic signals that involve the terminal. Another component of the transmission path is the one or more paths over which a radiated signal travels between the base station antenna element and the wireless terminal. By accounting for these propagation components through the use of measurement data provided by possibly a large number of wireless terminals, a disclosed location engine is able to derive adjusted measurements that are more representative of the propagation-time characteristic being measured by the individual terminals. These adjusted measurements can then be used to estimate the location of a wireless terminal more accurately.

Abstract: A method using Long Wave Infrared Imaging Polarimetry for improved mapping and perception of a roadway or path and for perceiving or detecting obstacles comprises recording raw image data using a polarimeter to obtain polarized images of the roadway or area. The images are then corrected for non-uniformity, optical distortion, and registration. IR and polarization data products are computed, and the resultant data products are converted to a multi-dimensional data set for exploitation. Contrast enhancement algorithms are applied to the multi-dimensional imagery to form enhanced object images. The enhanced object images may then be displayed to a user, and/or an annunciator may announce the presence of an object. Further, the vehicle may take evasive action based upon the presence of an object in the roadway.

Abstract: An improved method of tracking an object of interest. The tracking that is enabled by the disclosed tracking engine is based on location estimation of a wireless terminal combined with aerial or satellite imagery of an object of interest, in which a relationship has been determined to exist between the wireless terminal and the object of interest. In some tracking scenarios, a wireless telecommunications network can be used to direct an image-based surveillance system where to start observing, as an object of interest heads away from a heavily populated area or other area with satisfactory wireless coverage. In some other tracking scenarios, the trajectory of the object as derived from the image data enables the tracking engine to target a specific portion of the wireless network to utilize in generating the location estimates, thereby reducing the resource utilization of the wireless network and tracking engine.

Abstract: A technique for providing a location estimate of a mobile station, with increased accuracy. An unenhanced estimate of the location of a target mobile station is first obtained. A portable transmitter is then situated in an initial geographic area of interest defined by the unenhanced estimate. The portable transmitter is then tuned to transmit on a particular neighbor base station frequency being reported by the mobile station. When the portable transmitter is moved close enough to the target mobile station, the mobile station stops reporting the neighbor to the mobile's wireless telecommunications network, on account of the interference introduced by the portable transmitter being on that frequency. The estimated distance from the portable transmitter to the target mobile station depends on the transmit signal strength used by the portable transmitter. By considering these details, an enhanced estimate of the location of the mobile station can then be deduced.

The at least one flange has a first end adjacent the body, a second end generally opposite the first end and radially outward from the first end, a surface extending between the first and second ends and facing the circumferential belt engagement surface, and a length defined between the first and second ends. At least half the length of the surface of at least one flange facing the circumferential belt engagement surface is obtusely angled relative to the circumferential belt engagement surface.

Abstract: A disclosed detector estimates the wireless terminal as being indoors or outdoors by utilizing information that includes measurement report data from previous calls involving both i) wireless terminals that are known to have been indoors and ii) wireless terminals that are known to have been outdoors while the measurement report data was collected. Based on this call data, one or more classification features are computed in accordance with the illustrative embodiment of the present invention. Then, for a wireless terminal that is to be classified during a call and with respect to the terminal being either indoors or outdoors, features that are representative of that wireless terminal for the call are evaluated against a characterization that is a composite of one or more previously-computed classification features. The features that are representative of the wireless terminal can be derived from the measurement reports received from the wireless terminal during the call.
