Patent number: 9285453Abstract: A method of near-field electromagnetic ranging and location exploits the long-wavelength, near-field characteristics of low-frequency RF signals like those in the vicinity of the AM broadcast band. These signals are robust against scattering from small objects and only mildly perturbed by the urban landscape including building structures. They are thus amenable to an RF fingerprinting approach exploiting a coarse calibration to capture the behavior of the gradually varying signal characteristics. In embodiments, a method of near-field electromagnetic ranging and location may exploit transmit tags transmitting to an infrastructure of locator-receivers, or locator-receiver tags detecting signals from an infrastructure of fixed transmitter beacons. In still further embodiments, fixed transmitter beacons may be supplemented by uncooperative signals sources including signals-of-opportunity like AM broadcast band signals.Type: GrantFiled: December 3, 2012Date of Patent: March 15, 2016Assignee: Q-Track CorporationInventors: Hans Gregory Schantz, Robert Edward DePierre, Alfred Hans Unden, Eric Alexander Richards

Patent number: 9209525Abstract: A directive electrically small antenna (DESA) process and method employs multipole synthesis to implement directive electrically small multipole antennas with ultra-wideband (UWB) stable antenna patterns. Although lossy, embodiments have adequate efficiency to work as receive antennas in the high ambient noise environment of the HF band and below. Employing a process dubbed “antenna regeneration,” energy may be circulated within an antenna by means other than resonance. This enables multiple decade UWB response without the efficiency penalties inherent to traditional resistively-loaded antenna systems. Regenerative antennas can simultaneously achieve the performance of high Q resonant antennas and the bandwidth of resistively loaded antennas.Type: GrantFiled: April 1, 2012Date of Patent: December 8, 2015Assignee: Q-Track CorporationInventors: Hans Gregory Schantz, Robert Edward DePierre

Patent number: 8326451Abstract: An inventory control system and method uses a locating device associated with a mover and identifies an ID tagged asset using an ID reader also associated with the mover. Thus, a single relatively high-cost locating device may be temporarily associated with the asset, enabling precise location of a multitude of assets as a mover traverses an inventory area. The asset location and identification may be associated in a database. The asset location may be refined by using additional measurement devices, for example a forklift height sensor, to determine extension from a locating device. A further embodiment utilizes RFID or barcode technology for the ID tag. The locating device may utilize near-field location technology, signals-of-opportunity, or other RTLS technologies.Type: GrantFiled: June 6, 2011Date of Patent: December 4, 2012Assignee: Q-Track CorporationInventors: Hans Gregory Schantz, Peter J.

Publication number: 20120023572Abstract: A system and method for detecting and identifying intruders in a computer network environment by providing a network traffic evaluation and simulation module at the interface between a protected network and external traffic source. The evaluation and simulation module identifies suspected intruders by observing intrusion pattern behavior and then presents a simulated network to the intruder. The simulated network appears to offer the intruder valuable information and provides the intruder with the appearance of success in breaking down the layers of the simulated network to keep the intruder engaged in the intrusion effort while information is gathered to trace and identify the source of the intrusion. Intrusion attempts are identified and categorized in an intrusion analysis module. The network traffic evaluation and simulated network may be provided as a self contained physical module that does not require modification of existing network software.Type: ApplicationFiled: July 23, 2010Publication date: January 26, 2012Applicant: Q-Track CorporationInventors: Timmy P.

Patent number: 8018383Abstract: A signal-of-opportunity location device (SOLD) that may be situated in a complex radio propagation environment with multiple RF signal obstructions receives RF signals from a distant transmitter. The RF signals from the distant transmitter interact with obstructions in the propagation environment local to the SOLD. The local obstructions perturb the RF signals causing the RF signals to exhibit near field behavior in the complex radio propagation environment. The SOLD receives the locally perturbed signals. The SOLD detects signal characteristics of RF signal components of the received signals and compares these signal characteristics with reference data in a reference data store to determine the current location of the SOLD.Type: GrantFiled: June 8, 2010Date of Patent: September 13, 2011Assignee: Q-Track CorporationInventors: Hans Gregory Schantz, Alfred Hans Unden, Eric Richards, Robert Edward Depierre
