Patent number: 11353540Abstract: A method of processing incoming signals, such as RF signals, includes receiving the incoming RF signals at two (or more) spatially-separated receivers, then processing the signals to determine a phase lag between the two signals.

This can be used to produce a phase adjustment of one of the signals, allowing the signals to be coherently summed. The coherently summed combined signal is then examined for instances where a threshold magnitude is exceeded. This information is then used to create a blanking mask, which is then employed as a filter to incoming signals, to blank out non-coherent signals, such as noise and extraneous signals from sources that are not of interest. The blanked signal train is then examined/analyzed for constant pulse repetitions.Type: GrantFiled: December 19, 2019Date of Patent: June 7, 2022Assignee: Raytheon CompanyInventors: Henry B.

Patent number: 11150320Abstract: Within several applications the ability to localize an individual within an environment is beneficial. However, existing indoor localization approaches depend upon at least one of two assumptions. First, the subject(s) localization is achieved by localizing a wireless device carried by the subject and second, wireless fingerprints are established for the localization via a site survey being performed before a system can actually localize the subject(s). However, in many application scenarios, neither of the above two assumptions are true, namely that the user is not carrying an active wireless device or that the site has been surveyed. Accordingly, embodiments of the invention provide for subject localization by a dynamic calibration of wireless signals between a receiver and a transmitter, where neither the receiver or transmitter are associated with an electronic device carried or worn by the subject.Type: GrantFiled: July 7, 2020Date of Patent: October 19, 2021Assignee: Aerial Technologies Inc.Inventors: Yi Gao, Michel Allegue Martinez, Xi Chen, Xue Liu

That angle of arrival is then used to calculate the location of the UE. The angle of arrival may be a horizontal angle of arrival and/or a vertical angle of arrival.Type: GrantFiled: October 3, 2019Date of Patent: July 20, 2021Assignee: POLTE CORPORATIONInventors: Truman Prevatt, Michael John Buynak

Patent number: 11035947Abstract: The embodiments described herein provide ranging capabilities in RF-opaque environments, such as a jungle, utilizing transponders located on a property line. In particular, the embodiments described herein provide for determining a perpendicular distance to a property line from a ranging device. The transponders are located on the property line and a separated from each other by a known distance. The ranging device transmits RF signals to the transponders, which are received by the transponders and re-broadcasted back to the ranging device on a different frequency. The ranging device uses information about the transmitted and received RF signals and the known distance to calculate a perpendicular distance from the ranging device to the property line.Type: GrantFiled: November 6, 2018Date of Patent: June 15, 2021Assignee: Aerial Surveying, IncInventors: David Farrell, Thomas Pattison

Patent number: 10522022Abstract: The invention provides a system and method for receiving hazard and event information in a mobile unit and using that information to warn a user of an event or future hazard with reference to the mobile unit's location and/or intended direction of travel. A hazard location algorithm compares a forecast location of each mobile unit with a forecast hazard and transmits a warning to each mobile unit that is predicted to encounter the hazard. As the mobile unit moves, its actual position is updated in an event center, and a revised warning is transmitted to the mobile unit as applicable. Warnings include audio warnings for playback and/or visual warnings for display on the mobile device. Users may also wirelessly report events or hazards to a central server in an event center by sending data to the event center via a wireless communications network. Secondary information may be included, based on the selected event type.Type: GrantFiled: September 12, 2007Date of Patent: December 31, 2019Assignee: User-Centric IP, L.P.Inventors: Michael R.
