摘要： A system for monitoring operation and location of a moving first vehicle relative to a second vehicle. A minimum separation distance between the first and second vehicles is estimated, based on the first vehicle velocity, and optionally on the second vehicle velocity, using location determination (LD) signals received from satellite-based transmitters from GPS, GLONASS and LEO satellites, or from ground-based signal sources such as LORAN signal towers, and using ranging signals from SONAR, RADAR or a similar system. The minimum separation distance is compared with the actual separation distance at selected times, and a vehicle driver is advised if the actual separation distance is too small, if the separation distance is decreasing too quickly, or if the second vehicle velocity is decreasing too quickly. The second vehicle may travel in the same traffic lane, in an adjacent lane, or on a road that intersects the road used by the first vehicle. Where the first and second vehicles travel on separate roads that will intersect, the system estimates whether the second vehicle will stop, or will be able to stop, at the intersection. The second vehicle may be a railroad car, such as a locomotive, or a road vehicle, such as an automobile, bus or truck. A maximum vehicle clear-view velocity, consistent with vehicle stopping within a selected distance, is estimated. Road conditions are estimated and compensated for in estimating the minimum separation distance and/or the maximum vehicle clear-view velocity.

摘要： Apparatus and method for a location determination and reporting (LDR) system for clandestinely determining and reporting a missing vehicle present location. The vehicle is equipped with a handheld cellular phone unit and controller that are accepted and held by a cellular phone cradle that can include electrical poster and/or a location determination (LD) unit to determines the LD unit present location. The cellular phone unit can operate on one cellular channel or on two distinct cellular channels. When the vehicle is reported missing, the central station interrogates the vehicle LDR system to determine the vehicle present location. A location interrogation signal is transmitted, commanding the LD unit to transmit its present location. The cellular phone does not signal receipt of an incoming call for an initial time period of selected length .DELTA.td, awaiting possible receipt of a location interrogation signal on the first cellular channel. If the incoming call includes a location interrogation signal, the cellular phone does not "ring" but transmits information on the vehicle's present location to the central station. If the incoming call does not include a location interrogation signal, the cellular phone "rings" audibly or visually, after the initial time delay, and behaves as a normal cellular phone for that call on the second cellular channel. The cellular phone functions normally if a vehicle occupant attempts to use the phone. An unauthorized user of the vehicle receives no indication that the innocuous cellular phone is used to track the vehicle present location.

摘要： Apparatus and method for providing timing control signals for operation of an engine and other devices on a vehicle and/or operation of telecommunications equipment and/or computer equipment on the vehicle. A Satellite Positioning System (SATPS) antenna and receiver/processor receive and process signals from three or more SATPS satellites and determine and issue SATPS-determined timing pulses and time signals that indicate the time associated with each timing pulse. The pulse-to-pulse time separation .DELTA.t.sub.pp of these timing pulses is adjusted to provide a separation approximately equal to a selected pulse separation .DELTA.t.sub.incr. Alternatively, a supplementary timing device provides a sequence of timing pulses with pulse-to-pulse spacing that is adjustable by varying an environmental parameter .theta., such as temperature or electrical field, for this timing device. The supplementary timing device pulse-to-pulse separation is determined by the SATPS-determined time signals and the environmental parameter .theta. is varied so that .DELTA.t.sub.pp becomes approximately equal to a selected value .DELTA.t.sub.incr that can be used for timing signals on the vehicle. The supplementary timing device pulses can also be used where the SATPS-determined time signals and timing pulses are not available. The SATPS may be a Global Positioning System (GPS), a Global Orbiting Navigational Satellite System (GLONASS) or any other suitable satellite-based system.

摘要： Method and apparatus for providing security for a vehicle and for cargo transported on the vehicle. A location determination (LD) system determines vehicle location. A cargo unit carries a transceiver (or transmitter) that transmits a selected signal, either sua sponte or in response to receipt of a polling signal. The selected signal, if received by a receiver on the vehicle, is examined as to signal intensity, signal coding and/or time of receipt. If the received signal violates a selected condition, vehicle location is compared with an approved cargo destination. If the vehicle is not near a cargo destination, or if no selected signal is received at the receiver, an alarm signal is transmitted, which may include the vehicle location and/or the violated condition. If the LD system does not receive adequate LD signals to determine vehicle location, vehicle location coordinates are compared with a coordinate range for a signal obscuring region (SOR). Vehicle location within the SOR can be tracked using a supplemental LD system until the vehicle leaves the SOR. If LD signals are lost for too long, inside or outside an SOR, an alarm signal is transmitted. If vehicle location is outside a travel corridor, if the vehicle does not pass a waypoint, if vehicle velocity is below a low threshold for too long, or if vehicle velocity is above a high threshold, an alarm signal is transmitted. The LD system may be GPS, GLONASS, LORAN or other satellite- or ground-based system.

摘要： Methods for authentication or validation of the location of a putative source (ps) of a message, using time varying location determination (LD) signals that are received from J sources (J>1) of LD signals G(t;j;ps) that are spaced apart from the putative source. The putative source forms an augmented data signal that includes the original message, one or more segments g�t.sub.k(m),t.sub.k(m+1) ; j; ps!={G(t.sub.r ;j;ps).vertline.t.sub.k(m) .ltoreq.t.sub.r .ltoreq.t.sub.k(m+1) } of the LD signals for a selected time interval, a putative source asserted location L(t".sub.k(m) ;ps) for a time t".sub.k(m) in the selected time interval, and other identifying parameters. The augmented data signal is received by a central station that analyzes the LD signal segments and determines whether the asserted location L(t".sub.k(m) ;ps) is likely to be the true message source location. Part or all of the augmented data signal can be encrypted for transmission. One application is validation of use of licensed software on a computer whose location may be mobile. Another application is validation of votes cast from a plurality of remote voting sites.

摘要： A task description is stored in a database accessible by a mobile computer system. The mobile computer system receives positioning information corresponding to its geographic location and indexes the database based on the positioning information when the information indicates that the mobile computer system is in a geographic location that facilitates completion of a task associated with the task description. The database may be resident in the mobile computer system or accessible in other ways, for example, via the Internet. The task description preferably includes a geocode which corresponds to the geographic location at which completion of the task may be facilitated. The task description may also include textual, voice or other message which can be displayed and/or played back to a user. The positioning information may be obtained from a GPS satellite, a GLONASS satellite or a pseudolite. The mobile computer system may be a portable unit, such as a PDA, or integrated within a vehicle.
