Patent number: 11092665Abstract: The described disclosure presents embodiments of an efficient shortwave radio technique using a network of multiple sites located in and around an operating region (e.g., continental USA), calibrated distributed beacons, a detailed knowledge of ionospheric behavior, and sophisticated operational tools and software, that geo-locates targets without depending on satellites. The embodiments of the technique described herein, for example, accurately may locate a target by utilizing remote field units, a network of radio receive sites, receivers that accept and time stamp pertinent signals, demodulators that recognize and extract meaningful data from received signals, communications from all receive sites to a Network Operations Center (NOC), communications from NOC to field units to keep shortwave channel choices relevant and effective, and a processor within the NOC that analyzes and evaluates data.Type: GrantFiled: January 16, 2019Date of Patent: August 17, 2021Assignee: HYSKY TECHNOLOGIES, INC.Inventors: Charles C. Maynard, James V. Rootsey, Philip L. Galpin, C. Paul Smith-Goodson, Niles K. Chura

Patent number: 10547474Abstract: The present disclosure includes embodiments of a two-way wireless data communication system and associated methods. An embodiment of a system can include a network operations center (NOC), a plurality of fixed-location receive base stations (RBS) in communications with the NOC, and an intelligent shortwave communication network in communications with the NOC and the plurality of RBS and including a plurality of remote intelligent transceiver units (ITU). In an embodiment, for example, the NOC can be operative to a) compute rapidly a protocol under which nationwide communications is to be completed via coordinated operations of the linked ITU and RBS, b) determine propagating and clear electromagnetic wavelengths over an entire 3 MHz to 30 MHz shortwave band, and c) send a continuous stream of data indicating times and frequencies at which remote units can rapidly and efficiently transmit data and at which antenna sites can reliably and efficiently receive that data.Type: GrantFiled: October 29, 2018Date of Patent: January 28, 2020Assignee: HYSKY TECHNOLOGIES, INC.Inventors: James V.

Patent number: 5995804Abstract: A low power miniature repeater station is located on a vehicle such as a train, cargo ship, cruise ship or other vehicle which is expected to carry multiple paging receivers. The repeater station receives paging messages that originate as satellite signals and rebroadcasts them in the immediate vicinity of the vessel. The rebroadcast may typically be over a single FM carrier frequency or in the form of a subcarrier signal. The repeater includes an FM scanning receiver that samples the radio band and enables the rebroadcast of signals only if FM subcarrier signals are not detected within the vicinity of the vehicle. As the vehicle re-approaches a populated area, continued scanning of the radio band eventually detects the presence of subcarrier signals and shuts down the repeater to ensure that it will not interfere with licensed terrestrial broadcasters.Type: GrantFiled: January 16, 1997Date of Patent: November 30, 1999Assignee: Flash Comm.

Patent number: 3958192Abstract: A three-port transducer has as a first port a waveguide capable of supporting transverse electric waves of any polarization. The waveguide is divided into three sections by means of a pair of tapered septums which taper in opposing directions. The width of the inner section of the three is made equal to the combined widths of the other two and is coupled to a rectangular waveguide which comprises a second transducer port. The two outer sections are coupled together to a second rectangular waveguide which comprises a third transducer port. The polarization of a signal applied to the first port will determine the amplitude and phase of the signals at the second and third ports.Type: GrantFiled: April 23, 1975Date of Patent: May 18, 1976Assignee: Aeronutronic Ford CorporationInventor: James V.

Patent number: 3958193Abstract: A tapered septum in a square waveguide transduces it into a pair of rectangular waveguides. The output waveguides will be excited as a function of the polarization of the signals present in the square waveguide. The septum has a special shape that includes a tapered portion and a transverse portion proportioned to maximize the transducer bandwidth and minimize reflected power.Type: GrantFiled: April 23, 1975Date of Patent: May 18, 1976Assignee: Aeronutronic Ford CorporationInventor: James V.
