  • Patent number: 8493057
    Abstract: A detector detects an electromagnetic wave having a frequency of 0.01 THz?f?100 THz and transmitted through a device under test (DUT). A changer changes a relative position of an intersection of an optical path of the electromagnetic wave and the DUT, with respect to the DUT. A deriver derives a characteristic value of the electromagnetic wave based on a detection result of the detector, while the characteristic value is associated with an assumed relative position, which is the relative position if the electromagnetic wave is not refracted by the DUT. A corrector changes the assumed relative position to an actual relative position, which is the relative position if the refraction of the electromagnetic wave by the DUT is considered. A corrected deriver derives the characteristic value associated with a predetermined relative position based on an output from the corrector.

The mail items are advanced at a constant speed V along a reference surface. The presence of a mail item is detected relative to a given point of the reference surface. First and second times t1, t2 for which the same mail item is present at the first and second distances d1, d2 relative to the reference surface is detected. The ratio t2/t1 is compared with a value equal to (1??), where ? represents a correction coefficient of less than 1 that depends on the tolerances for detection of the presence of a mail item. The height of a mail item is considered greater than the dimensional threshold SH if, and only if, the relationship t2/t1>1?? is true.

  • Patent number: 7569825
    Abstract: An inspection device includes a light source emitting ultraviolet light onto a banknote conveyed on a conveyance path, a light source emitting infrared light onto the banknote, a photosensor for detecting light from the banknote, a light source control processing portion for controlling the light sources while individually switching the light sources at high speed, and a discrimination processing portion. The discrimination processing portion first imports each of two detection signals (output signals) from the photosensor, which are obtained by substantially within an identical period of time when the banknote is illuminated with the light through sequential lighting of the light sources and calculates an output ratio of the photosensor. Then the calculated output ratio of the photosensor is compared and collated with reference data preliminarily stored in a memory, determining authenticity and denomination of the banknote.

  • Publication number: 20090101826
    Abstract: A multi-stage process utilizing one or more radiation sensors on a distributed network for the detection and identification of radiation, explosives, and special materials within a shipping container. The sensors are configured as nodes on the network. The system supports extended time options at each node and the ability to combine data from multiple nodes for the data acquisition and analysis of shipping containers. The system collects radiation data from one or more nodes and compares the collected data to one or more stored spectral images representing one or more isotopes to identify one or more isotopes present. The identified one or more isotopes present are corresponded to possible materials or goods that they represent. The possible materials or goods are compared with the manifest relating to the container to confirm the identity of materials or goods contained in the container or to detect and/or identify unauthorized materials or goods in the container.

  • Patent number: 7265353
    Abstract: A system for detecting and identifying low-level (weak) radioactive sources moving past stationary detectors. The system, which can detect low-level sources moving at speeds of 30 m/s (about 70 mph), uses the differences between background counts and gamma counts from a moving source to determine that a source has passed the detector, when a source has passed the detector, and the identification of the source. This system has been demonstrated to work successfully for ordinary passenger vehicles transporting a variety of sources, and also for boats at lower speeds on a waterway.
