A technique is provided for detecting whether an object of interest is being carried by a subject. The technique includes coarsely scanning the subject with an electromagnetic radiation, measuring reflective intensity of radiation reflected from the subject, and detecting the presence or absence of the object of interest based upon the measured reflective intensity.

System and method for detecting contraband

The device for detecting damage of a wind energy turbine of a wind energy turbine rotor blade, due to a lightning strike, comprises several magnetic or electric field sensors distributed along the length of a rotor blade of the wind energy turbine for measuring the magnetic or electric field concentration along the rotor blade and, an evaluation unit connected to the magnetic or electric field sensors for receiving the measured signals thereof, wherein damage of the wind energy turbine of the rotor blade caused by a lightning strike is calculated by the evaluation unit based on the measured concentration of the magnetic or electric field along the length of the rotor blade.

A technique is provided for examining a subject. The technique includes illuminating at least a part of the subject with THz radiation and detecting THz radiation reflected and/or transmitted from the illuminated part and incident upon a detector array by measuring change in capacitance corresponding to the incident THz radiation.

Terahertz detectors for use in terahertz inspection or imaging systems

A method for directing a current generated by a lightning striking a wind turbine is described. The method includes directing the current from a main shaft of the wind turbine to a brake disc attached to the shaft, and directing the current from the brake disc to one of a spark gap and a roller mechanism coupled to a down-conductor at a ground voltage.

Systems and methods for directing a current

The method for controlling a first wind energy turbine of a wind park comprising multiple wind energy turbines connected to the grid, in situations where the first energy turbine operates substantially at zero energy output level, comprises the steps of determining whether at least one of the other wind energy turbines of the wind park is operated above a predetermined energy output level, and if at least one of the other wind energy turbines of the wind park is operated above the predetermined energy output level, maintaining connection of the first wind energy turbine to the grid.

A security detection system includes a radiation source configured to generate and direct terahertz radiation onto an object. Further, the system also includes a detector module configured to detect and process radiation from the object, the detector module comprising a parallel arrangement of at least two low noise amplifiers, each operable in a respective frequency band.
