An object of the present invention is to provide a charging system which carries out position confirmation of a moving body at a place where there is a radio wave blocked facility, and which carries out automatic detection of GPS antenna blockage for avoiding charging. In a charging system including a GPS positioning device 921 for recognizing a vehicle position, a vehicle speed pulse measuring device 920 for dead reckoning navigating, a monitor device 920, 927, 928 which generates information expressing a current position by using these, and a charging processing 902 which judges whether or not a recognized current position is within a charge area and which carries out data processing for charging, the monitor 920 includes a simple map database 928 which includes positions of facilities or geographical features at which GPS positioning is impossible, and when GPS positioning is impossible, the facility or geographical feature corresponding to the current position is detected, and that position is made to be a current position.

Two GPS units are mounted at two separate points on the body of a work machine to periodically measure their three-dimensional coordinates with respect to a chosen reference system. As soon as two sets of measurements are recorded, a plane is fitted through the four points so collected and it is used to determined the current orientation of the machine. As each additional set of position data is collected at predetermined intervals for the two points on the machine, a new plane equation is calculated to update the orientation of the machine based on a predetermined number of prior measurements. Standard-deviation analysis is used to check the validity of each plane calculation and the process is restarted when the deviation is found to be greater than an acceptable parameter. Based on the current coordinates of the two GPS antennae, the current orientation plane so calculated, and the known geometry of the work machine, the current position of its critical components can be determined as well irrespective of the specific motion pattern of the machine.

The present invention comprises systems and methods for cellular, PCS, GPS and/or Bluetooth mobile communication (e.g., a mobile telephone). The systems and methods employ a fully integrated dual band IFA/loop CDMA antenna for cellular and PCS communication. Fully integrating the CDMA antenna within a PWB provides for mitigation of lumped elements to establish dual banding, and can provide for reduced antenna size, device size, cost and interference form a user's hand. The IFA antenna is configured to transmit and receive within the cellular frequency band via a capacitive tap, and the loop antenna is configured to transmit and receive within the PCS frequency band via an impedance matching stub and ground location. The system and methods further employ a firewall to mitigate antenna coupling, and a metal reflector to reduce the electromagnetic reflection, and improve antenna gain and efficiency.

An apparatus, system, and method for determining characteristics of a roadway mark at a remote location. The system includes a vehicle having at least one imager for producing image data containing at least one actual roadway mark evident on a roadway surface. A GPS antenna is mounted on the vehicle. A GPS receiver is responsive to the GPS antenna for determining a GPS location of the GPS antenna. An apparatus responsive to the imager and the GPS receiver determines a GPS location of the roadway mark and filters and compresses the image data, the filtered and compressed image data containing the image data of the roadway mark. An apparatus communicates the filtered and compressed image data to the remote location for analyzing the roadway mark characteristics from the image data.

A system determines three-dimensional attitude of a moving platform using signals from two closely spaced Global Positioning System (GPS) antennas. The system includes three rate gyroscopes and three accelerometers rigidly mounted in a fixed relationship to the platform to aid in determining the attitude. The system applies signals from one of the two GPS antennas to sufficient channels of a GPS receiver to support navigation. The system applies signals from a second of the two GPS antennas to the additional receive channels to support interferometry. The system resolves the ambiguity normally associated with the interferometric heading solution by having closely spaced GPS antennas, and uses interferometry to refine a coarse heading estimate from a GPS plus Inertial Measurement Unit (IMU) transfer alignment solution. The system achieves sub-meter spacing of the two GPS antennas by merging many temporal interferometric measurements and the attitude memory provided by the IMU time-history solution.

An apparatus for providing Global Positioning System (GPS) position data to an underwater diver for use in navigation is comprised of a SCUBA Flag/Antenna Float, positioned on the surface of the water, containing a Spring-loaded Cable Reel which is connected via a Signal Umbilical Cable to a GPS Capsule carried by the underwater diver. A GPS Antenna and power supply provide a signal to a GPS Receiver/Display which is encased in the GPS Capsule. The diver views icons displayed on the GPS Receiver to determine his/her current position in relation to previously entered waypoints, or geographical coordinates, such as a wreck, dive boat, or locations of interest plotted by the diver during the dive. The position information displayed by the GPS receiver enables the diver to navigate to and from the various locations or geographical coordinates while submerged.
