20130214975 | TARGET LOCATION POSITIONING METHOD AND DEVICE - An inventive precision pinpoint tracking method and system is provided for devices that provide spot location measurements of objects. Embodiments of the location measuring device have a RF antenna, a tracking module in electrical communication with the RF antenna, and a tilt-compensated (TC) compass. In embodiments of the location measuring device, a measuring tip is offset at a distal end from the tracking module and the RF antenna is located at the proximal end of the tracking module. In embodiments, the TC compass provides data to calculate a translation of the position of the measuring tip with respect to the RF antenna to enable spot measurements of locations of a target object. | 08-22-2013 |
20110313716 | INTERTIAL TRACKING SYSTEM WITH PROVISION FOR POSITION CORRECTION - A subject location tracking process is provided that includes the attachment of a system to a subject where the system includes a radiofrequency sensor integration module, an inertial tracking module, and a microprocessor. Radiofrequency signals are communicated from the radiofrequency sensor integration module to a remote radiofrequency transceiver beacon. A measured range is determined between the radiofrequency sensory integration module and the beacon. An error value E is then computed between the measured range and a predicted range. The predicted range is computed from the inertial tracking module alone based on positional data as to location and orientation of the system. The location data of the subject is determined with a microprocessor and displayed at the location. The present invention operates to provide a high degree of accuracy as to the position of a subject in spite of intermediate obstructions and without reliance on global position satellite systems, fixed reference signals, or line of sight. | 12-22-2011 |
20110148710 | DISTANCE SEPARATION TRACKING SYSTEM - A distance separation tracking process is provided that includes the transmission of a periodic radio frequency original signal from a beacon transceiver. The original periodic signal from the beacon transceiver is received at a remote target transceiver as a target received periodic signal. The target retransmits the received periodic signal to the beacon transceiver as a return periodic signal. Data points of the return periodic signal are sampled and used to calculate a phase differential between the original periodic signal and the return periodic signal that correlates to the distance separation range between the beacon transceiver and the target transceiver. | 06-23-2011 |
