Patent number: 11851900Abstract: A temporary upright post includes rail supports for holding temporary lateral guardrails and a mounting system for mounting to a permanent upright stanchion of a permanent railing system for an elevated surface. The mounting system includes a longitudinal bore in the lower portion of the upright post that removably receives the stanchion with a loose fit, and the mechanical securement tightens the post to the stanchion to secure them together for use and loosens to release the post for installation and removal. Example embodiments also include a support bearing that is repositionable to contact and support the post in an elevated position on the stanchion, up and away from the elevated surface, or to disengage from mechanical interference with the stanchion so the post can be lowered to the use position.Type: GrantFiled: January 30, 2020Date of Patent: December 26, 2023Inventors: James Croswell Brim, III, Robert Paul Hanes, Jr., Hunter Moore, Brian Keaton, David A.

Patent number: 11606798Abstract: A terrestrial communication systems, specifically a signal collision avoidance system between a terrestrial transmitter and an airborne receiver, is disclosed. The terrestrial communication system includes an electronic processor configured to determine a receive frequency from a nearby airborne receiver, determine a transmit frequency from a communicatively coupled terrestrial transmitter, and modify the transmit frequency of the terrestrial transmitter based on the determined receive frequency and transmit frequency. To modify the transmit frequency, the electronic processor compares the receive frequency and the transmit frequency to determine a channel type. Based on the determined channel type, including co-channel and adjacent-channel, the electronic processor modifies a spectrum signature of the transmit frequency so that the transmit frequency does not interfere with the receive frequency of the airborne receiver.Type: GrantFiled: March 3, 2021Date of Patent: March 14, 2023Assignee: ATC Technologies, LLCInventors: Ilya Ziskind, David Nance

Patent number: 10775802Abstract: A network system for controlling a vehicle speed includes a server, a satellite, and a control device for monitoring and modifying a speed of the vehicle. The server receives information relating to at least one travel condition, calculates a target speed based on the at least one travel condition, and transmits one or more commands indicative of the target speed. The satellite is communicatively coupled to the server and receives the command(s) indicative of the target speed. The control device includes a speed sensor generating a signal indicative of a sensed vehicle speed, a receiver communicatively coupled to the satellite and receiving the command(s) indicative of the target speed, and a controller. The controller calculates a difference between the target speed and the sensed vehicle speed, and modifies operation of a prime mover and/or traction elements to cause the sensed vehicle speed to match the target speed.Type: GrantFiled: August 30, 2018Date of Patent: September 15, 2020Assignee: ATC TECHNOLOGIES, LLCInventors: David Nance, Ilya Ziskind

Patent number: 10708188Abstract: Systems and methods for exchanging data over a network are described. One method includes receiving, from a computing device via a physical network port, a request to forward network traffic, the request including a network domain identifier and a user identifier. The method includes retrieving, from a database storing user information, a user profile based on the user identifier. The method includes determining whether the traffic forwarding request is valid based on the user profile. The method includes, when the traffic forwarding request is valid, provisioning, on the network, an application service virtual circuit between a local virtual port of a communication interface coupled to the electronic processor and a peer port at a remote communication endpoint. The method includes forwarding the network traffic from the computing device to the remote communication end point via the application service virtual circuit.Type: GrantFiled: January 31, 2019Date of Patent: July 7, 2020Assignee: ATC TECHNOLOGIES, LLCInventors: Ilya Ziskind, David Nance

Patent number: 10615866Abstract: A system includes a modulator, a beam former, earth equipment, and a spotbeam satellite. The modulator is configured to receive localized content, generate N localized content delivery platform frames from the localized content, and generate intermediate frequency (IF) carriers that are modulated with the N localized content delivery platform frames. The beam former is configured to process the IF carriers to enable beamforming in a satellite service band. The earth equipment is configured to frequency translate the IF carriers that are processed into feederlink signals in a feederlink band, and transmit the feederlink signals. The spotbeam satellite is configured to receive the feederlink signals, generate a multicast transmission by frequency translating the feederlink signals to the satellite service band, and transmit the multicast transmission to form N spotbeams, N being an integer greater than zero.Type: GrantFiled: November 13, 2018Date of Patent: April 7, 2020Assignee: ATC TECHNOLOGIES, LLCInventors: Ilya Ziskind, David Nance, Santanu Dutta
