Abstract: The present disclosure relates to systems and methods for ionizing a surface. In one implementation, an ionization source may include a microhollow cathode plasma or micro cavity plasma (MCP)-based ion source having a cavity and generating a plasma. A gas stream may pass through the cavity and transport the plasma. The source may further include one or more conductive electrodes located downstream from the MCP and configured to have a potential relative to the MCP such that positive and negative ions included in the plasma are carried through the electrodes by the gas stream. In another implementation, a mixer may mix a dopant (e.g. water) with the gas stream (e.g. air) entering the discharge. The disclosure also relates to a surface ionization probe.

Abstract: Implementations described and claimed herein provide an RFID locking apparatus including an RFID tag, a locking member, and a disabling member. The RFID tag is disposed inside a housing and has a chip and an antenna that emits a signal. The locking member includes a tube that extends outwardly from within the housing and a cable connected to the disabling member and exiting the housing via the tube. The locking member configured to compress a spring into a loaded state by pulling the cable. The disabling member is disposed near the spring inside the housing and is configured to destroy the antenna and/or the chip, such that the signal cannot be emitted, upon release of the spring from the loaded state. The RFID locking apparatus is configured to release the spring when the locking member is damaged.

Abstract: An autonomous mine detection and neutralization system including a motorized underwater vehicle having a guidance control component, and a vehicle positioning system attached to the vehicle via a communications cable. The system also includes a buoyant surface unit comprising a protective housing surrounding an interior chamber, a positive buoyancy buoy attached to the housing, an antenna system attached to the housing, and a radio transmitter and receiver system positioned within the chamber, which radio transmitter and receiver system is electrically attached to the vehicle positioning system and the antenna system. The mine detection system is launched into a body of water from an air craft or surface vessel. The vehicle then proceeds to an underwater target on its own, relaying navigation data and imagery through a communications cable to a surface unit which relays the information over a radio frequency link to a remote user.

Abstract: A towed body yaw angle sensor arrangement used to sense the angle between the axis of a tow fish and the flow of water. The water flow vector is used as the reference for correcting towed body yaw so that a magnetic compass in the towed body is aligned with the towed arrays streaming in the water flow. A yaw angle in the towed body with respect to the flow will cause errors for target bearing and skew the arrays relative to each other which will also cause errors. The flow sensor must be in the free flow off the towed body and ideally the sensing part is aligned with water current flow. Also provided is a method for sensing and correcting a yaw angle.
