Patent number: 9288623Abstract: An autonomous system with no Customer Network Investment is described, wherein the system is configurable to operate on in a band in addition to the LTE band. Such system allows the definition of hybrid operations to accommodate the positioning reference signals (PRS) of LTE and already existing reference signals. The system can operate with PRS, with other reference signals such as cell-specific reference signals (CRS), or with both signal types. As such, the system provides the advantage of allowing network operator(s) to dynamically choose between modes of operation depending on circumstances, such as network throughput and compatibility.Type: GrantFiled: October 1, 2013Date of Patent: March 15, 2016Assignee: INVISITRACK, INC.Inventors: Felix Markhovsky, Truman Prevatt

Patent number: 8886223Abstract: A system for determining location of an object including a Master Unit having an RF transceiver and adapted to measure distance to a Tag. The Master Unit has a first input from which it can derive its current position, transmits instructions to the Tag for movement in a predetermined direction, measures distance to the Tag after the movement in the predetermined direction, and determines position of the Tag after the movement in the predetermined direction. The Tag and Master Unit can include a compass, a pedometer, an accelerometer, a solid-state gyroscope, an altimeter inputs for determining its current position by the Master Unit. The Master Unit can optionally include a GPS receiver. The Tag movement does not have to follow the Master Unit's direction, but the Master Unit will still be able to determine the Tag location(s). The roles of the Master Unit and Tag can be reversed.Type: GrantFiled: March 11, 2013Date of Patent: November 11, 2014Assignee: Invisitrack, Inc.Inventors: Russ Markhovsky, Evgenii Mikhienko, Evgenii Vityaev
