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 defined by the unenhanced estimate. The transmitter is then tuned to transmit a particular identifier on a particular frequency. When the transmitter is moved close enough to the mobile, the mobile starts reporting the identifier to the mobile's wireless network. Because the identifier and frequency are carefully selected so as not into interfere with ongoing operations of the wireless network, the wireless network itself merely regards the reported data to be invalid for handoff purposes. The estimated distance from the transmitter to the mobile depends on the transmit signal strength used by the transmitter. By considering these details, an enhanced estimate of the location of the mobile can then be deduced.

Abstract: A location engine that accounts for propagation-time components in an antenna system disposed between i) the base station that serves a wireless terminal and ii) the airwaves over which electromagnetic signals propagate between the antenna elements and wireless terminal. By considering and accounting for these propagation components, the location engine is able to estimate information about the antenna system, such as i) whether the antenna system is a distributed antenna system and ii) the configuration of the antenna system. Based on this estimated information, the location engine is also able to estimate adjustments that can be made to location-related measurements, and, with these adjustments, estimate the location of one or more wireless terminals.

Abstract: A system and method for interfacing an autonomous or remote control drive-by-wire controller with a vehicle's control modules. Vehicle functions including steering, braking, starting, etc. are controllable by wire via a control network. A CAN architecture is used as an interface between the remote/autonomous controller and the vehicle's control modules. A CAN module interface provides communication between a vehicle control system and a supervisory, remote, autonomous, or drive-by-wire controller. The interface permits the supervisory control to control vehicle operation within pre-determined bounds and using control algorithms.

The snowmobile further includes a plurality of ground-engaging members cooperating with the power train unit to operate the snowmobile. The plurality of ground-engaging members includes a pair of front skis and an endless track assembly. A snowmobile is also depicted which has a raised front chassis relative to the drives haft, which raises the clearance of the front chassis for deep snow.

Abstract: A technique for designing and testing drive-test plan for gathering location-dependent RF data is disclosed. In accordance with some embodiments of the present invention, one candidate drive-test plan is chosen for implementation over a second based on an economic cost-benefit analysis of both plans. This is in marked contrast to, for example, a selection of drive-test plans, or the design of a drive-test plan, based on a calibration-cost analysis, in which the data estimated to be the most effective to calibrate a radio-frequency tool is sought for a given cost or the least cost. Although a data-estimated-to-be-most-effective-to-calibrate-a-radio-frequency-tool vs. cost analysis is a species of cost-benefit analyses in general, it is not an economic cost-benefit analysis because a data-estimated-to-be-most-effective-to-calibrate-a-radio-frequency-tool vs. cost analysis has deficiencies that an economic cost-benefit analysis does not.

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.

Abstract: An illustrative telecommunications analysis server analyzes telecommunications-event records and telecommunications-activity records associated with mobile stations operating in one or more wireless networks to infer whether a spike in initiated telecommunications activities occurred in a period of time and from a geographic area that closely correlate with the time and location of an audio incident. The server corroborates that the audio incident likely occurred based on the inferred spike in initiated telecommunications activities from one or more mobile stations. The illustrative server identifies the mobile stations that were likely within earshot of the incident and actively initiating telecommunications immediately thereafter.

Abstract: Improvements in a self-tightening holding strap that grips onto a tube. The strap uses an elastomeric cushion with hook and loop fasteners to hold the strap onto a tubular pipe. The hook and loop fasteners allows the self-tightening holding strap to be easily installed, removed and repositioned where desired. The elastomeric cushion conforms around a textured or powder coated surface to increase the gripping forces. The elastomeric cushion can expand slightly as forces increase but retain the high grip. A tightening clasp allows an installer to pull from only one side of the self-tightening holding strap with one or both hands and using the elastomeric cushion to prevent the self-tightening holding strap from sliding on the pole. The self-tightening holding strap to be sewn onto a cover, canopy or strap.

Abstract: A technique for deriving the locations of one or more wireless base stations is disclosed. After initializing values for the base station location coordinates, a server acquires reference coordinates of a wireless terminal, which are provided from an independent source, and also acquires values for one or more time-of-occurrences of events associated with signals that travel between the wireless terminal and the base stations. The server generates predicted coordinates of the wireless terminal, based in part on the current base station coordinates, by using trilateration. The server then generates updated base station coordinate values, based on a method of least squares, in which each residual is a difference between the reference and predicted coordinates of each wireless terminal location, for one or more wireless terminals. The server modifies the base station coordinate values so as to minimize the least-squares function.

Abstract: A technique for deriving timing information across wireless base stations is disclosed. After initializing values for base station time-offset parameters, a server acquires reference coordinates of a wireless terminal, which are provided from an independent source, and also acquires values for one or more time-of-occurrences of events associated with signals that travel between the wireless terminal and the base stations. The server generates predicted coordinates of the wireless terminal, based in part on the current time-offset values, by using trilateration. The server then generates updated time-offset values, based on a method of least squares, in which each residual is a difference between the reference and predicted coordinates of each wireless terminal location, for one or more wireless terminals.
