An embodiment disclosed herein is directed to a method of monitoring an electromagnetic shield effectiveness including transmitting a first electromagnetic field toward a first surface of an electromagnetic shield, detecting a second electromagnetic field transmitted from a second surface of the electromagnetic shield, generating a first signal corresponding to the second electromagnetic field and determining whether a defect exists at the electromagnetic shield by comparing the first signal to a predetermined threshold.

Electromagnetic shielding defect monitoring system and method for using the same

A system for generating a high voltage energy pulse comprises a capacitive energy storage arrangement that is coupled to a direct current (DC) power supply. The capacitive energy storage arrangement stores energy from the power supply. The system also includes a pulse forming network for forming frequency contents of a high voltage energy pulse. A dielectric insulated mechanical switch is coupled to the capacitive energy storage arrangement and the pulse forming network. The dielectric insulated mechanical switch is immersed in a dielectric substance. A controller is coupled to the dielectric insulated mechanical switch. The controller is programmed to selectively open and close the dielectric insulated mechanical switch so as to supply energy stored in the capacitive energy storage device to the pulse forming network and thereby form the high voltage energy pulse.

Tunable electrical transient generator for electromagnetic pulser

An embodiment disclosed herein is directed to an electromagnetic shielding defect monitoring system that includes a transmit system adapted to transmit a first electromagnetic field toward a first surface of an electromagnetically shielded enclosure, thereby generating a first current on the first surface, a stationary receive system adapted to detect a second electromagnetic field transmitted from a second surface of the electromagnetically shielded enclosure by a second current induced on the second surface by the first current and to generate a corresponding detected signal; control circuitry adapted to control operations of the transmit and receive systems; and analysis circuitry adapted to identify a location of a defect in the electromagnetically shielded enclosure based upon operations of the transmit and receive systems and based upon the detected signal.

An electronic vehicle disabler system and method uses a current supply capable of delivering an electrical current to a fleeing or moving vehicle that inhibits self-propelled movement of the vehicle. The electrical current is delivered by establishing a momentary forward current path between the vehicle and the current supply, at the same time that a return current path between the vehicle and current supply is established. The forward and reverse current paths may, e.g., include electrically conductive wires or electrically conductive streams of fluid or gas. The forward and reverse current paths are electrically coupleable to the fleeing vehicle through a variety of direct conductive linkages that are temporarily or permanently laid down on a roadway over which the fleeing vehicle passes, or that are coupled to the fleeing vehicle from a pursuing vehicle.
