Abstract: An unmanned, remotely controlled microwave-powered aircraft for use as a stationary communications platform. The aircraft is generally a flying wing with a large, flat inner wing having a rectenna on the underside. Rectennas may also be provided on the underside of the wings, the combined output from the rectenna being used to provide power to two electric motors housed within torpedo-shaped nacelles which drive two rear propellers. The rectenna converts a microwave signal at 35 GHz generated by a ground power station utilizing dual gyrotrons and a 34-meter diameter antenna dish. The aircraft has a preferred airfoil cross section throughout and is constructed of lightweight but strong materials in order to provide an enhanced flying time of several months. A power management and distribution system manages the DC power produced by the rectenna to supply power to the flight controls, propulsion system and payload.

Abstract: An authorization system includes a controller of an external computing device communicatively connected to an unmanned aerial vehicle (UAV). The controller obtains a mission kit that includes software for controlling a piece of equipment configured to be assembled on the UAV. The controller receives a license that is associated with a user and determines, based on the license, whether the piece of equipment is authorized for operation on the UAV as controlled by the user. Responsive to determining that the piece of equipment is authorized, the controller initiates transmission of at least some of the software of the mission kit to the UAV for installation by the UAV to allow the user to operate the piece of equipment.

Abstract: The present invention discloses an advanced emergency response system that minimizes physical risk to the first responder and yet allows them to maintain national safety and security within the country. The apparatus involves receiving alerts through the dispatch system located in the first responder car. The first responder car, upon receiving an alert, is dispatched to the appropriate address and is parked within a safe distance from the emergency location. The first responders then dispatch the autonomous rover from their vehicle using a vehicle dashboard. The rover is equipped with cameras, an object detection system, location sensors, and it shares live feeds for situational awareness with the public safety agencies and first responders. It also enables real-time bidirectional communication for first responders, public safety agents and allows them to communicate with the suspects and the victims located at the hazard/emergency site. The system also uses Artificial Intelligence (AI) algorithms to detect safety and security anomalies associated with the emergency situation in the field and shares this information with the public safety agents. If the suspect decides to run and take off, this system allows the first responders to launch a swarm of drones using cognitive vehicle dashboard that keep track of the suspect and provide situational awareness to the first responders and the public safety agents. All components involved in this system use Public Safety Grade FCC Band 14 Telecom Network for wireless communication dedicated to public safety agents and this network provides mission-critical reliability and security. The assembly is easy to install, safe to use, and suitable for all public safety agents and first responders.

Abstract: A system for bistatic radar target detection employs an unmanned aerial vehicle (UAV) having a ramjet providing supersonic cruise of the UAV. Deployable antenna arms support a passive radar receiver for bistatic reception of reflected radar pulses. The UAV operates with a UAV flight profile in airspace beyond a radar range limit. The deployable antenna arms have a first retracted position for supersonic cruise and are adapted for deployment to a second extended position acting as an airbrake and providing boresight alignment of the radar receiver. A mothership aircraft has a radar transmitter for transmitting radar pulses and operates with an aircraft flight profile outside the radar range limit. A communications data link operably interconnects the UAV and the tactical mothership aircraft, transmitting data produced by the bistatic reception of reflected radar pulses in the UAV radar antenna to the mothership aircraft.

Abstract: Various aspects of the present disclosure provide for methods, apparatus, and computer software for multiple access to a channel carrying a common uplink burst transmitted by users that utilize two different modes. Specifically, a coupled mode provides for range extension for users at a cell edge, while a decoupled mode provides for user data transmissions within the common uplink burst. Multiple access between these different modes may be provided in a non-orthogonal scheme by moderating the amount of interference between the respective modes. Further, multiple access between these different modes may be provided in an orthogonal scheme by utilizing interleaved frequency division multiple access (IFDMA).
