Abstract: A barrier sleeve usable with a protective gown, the barrier sleeve having a tubular cuff section including a cuff material and having a cuff section first end and a cuff section second end, and a tubular gasket section having a gasket material, the gasket section having a gasket section first end at the cuff section second end and a gasket section second end, the gasket material also including a gathered material and/or an extensible material, and the gasket material having a first thickness and able to exhibit a change in thickness upon compression of at least about 40%. Also disclosed are systems having the barrier sleeve, methods of making, and methods of using.

Abstract: Systems and methods for calculating coherent bearing that allow one to reduce the number of TCAS antenna elements. In one embodiment, the bearing calculation takes into account signal-to-noise ratio (SNR) difference experienced from top and bottom antennas mounted on a vehicle.

Abstract: Systems and methods are operable maintain a proscribed Self Separation distance between an unmanned aircraft system (UAS) and an object. In an example system, consecutive intruder aircraft locations relative to corresponding locations of a self aircraft are determined, wherein the determining is based on current velocities of the intruder aircraft and the self aircraft, and wherein the determining is based on current flight paths of the intruder aircraft and the self aircraft. At least one evasive maneuver for the self aircraft is computed using a processing system based on the determined consecutive intruder aircraft locations relative to the corresponding locations of the self aircraft.

Abstract: A device for determining the bearing of a vehicle using Inertial Reference Unit (IRU) and Traffic Alert Collision Avoidance System (TCAS) data. The device includes a means to communicate with the vehicle such as a transmitter, receiver, and antenna. The device also includes a processor configured to receive the IRU and TCAS data from the vehicle via the communication means and then generate a bearing value using the received data.

Abstract: A position keeping system, useable to maintain a position of a vehicle in a vehicle formation, to keep all formation members flying at a specified velocity and altitude, and to perform commanded maneuvers, determines guidance corrections based on a track state referenced to a leader or a virtual leader of the formation and on a formation position error indicating the error in the position of the vehicle in the formation. The guidance corrections are required so as to maintain the vehicles in the formation.
