Embodiments of the invention include a system and a method for determining whether a person is carrying concealed contraband, such as an improvised explosives device or other weapon. The system includes a people tracking video subsystem, a people tracking decisioning subsystem, a concealed contraband detection aiming subsystem, and a concealed contraband detection decisioning subsystem.

Standoff detection systems and methods

A system includes a generator configured to output at least one voltage level and an x-ray source configured to generate x-rays directed toward an object. The system includes a module coupled to the output of the generator and to an input of the x-ray source and configured to switch or assist in switching an output to the x-ray source between a first voltage level and a second voltage level.

System and method of fast switching for spectral imaging

A protection system for a power distribution system with one or more zones that includes at least one power-switching device connected to a power or current sensing device and a communications device. The power-switching device is communicatively coupled to at least one processing device. The at least one processing device is adapted to execute a plurality of protective functions for a zone based on information of power conditions within the zone and predetermined protective requirements of the zone.

Circuit protection system

A method of protecting a circuit having power switching devices that includes communicating a current in at least one secondary switching device to at least one master switching device and determining a presence of a fault condition within at least a first zone based at least in part upon characteristics of the current in the at least one secondary switching device communicated to the at least one master switching device to perform differential protection.

This series-capacitor compensation equipment comprises a series-capacitor bank in series with a power line and an overvoltage protection circuit for the capacitor bank comprising the series combination of a surge arrester and electric bus structure connected in series with the power line and in parallel with the capacitor bank. The surge arrester includes metal-oxide varistor elements which impart a relatively high resistance to the arrester when the voltage across the arrester is in a normal range and a relatively low resistance when the voltage across the arrester rises to a predetermined value that produces arrester operation. The capacitor bank will discharge through the overvoltage protective circuit should a varistor element fail during arrester operation. The bus structure comprises stainless-steel bus conductor having a resistance that is sufficiently high to effectively limit the energy duty on the arrester during discharge of the capacitor bank through the overvoltage protection circuit in the event of failure of a varistor element during arrester operation.
