Multiple tomogram system means a computed tomography X-ray system which obtains X-ray transmission data simultaneously during a single scan to produce more than one tomogram.
Fuel system means the components which store or transport fuel on board the vehicle and comprise the fuel tank system, all fuel and vapour lines, any non-tank mounted fuel pumps and the activated carbon canister.
Tomogram means the depiction of the x-ray attenuation properties of a section through the body.
Fluoroscopic imaging assembly means a subsystem in which X-ray photons produce a visual image. It includes the image receptor(s) such as the image intensifier and spot-film device, electrical interlocks, if any, and structural material providing linkage between the image receptor and diagnostic source assembly.
Feed means feed as defined in point (4) of Article 3 of Regulation (EC) No 178/2002;
Cabinet x-ray system means an x-ray system with the x-ray tube installed in an enclosure independent of existing architectural structures except the floor on which it may be placed. The cabinet x-ray system is intended to contain at least that portion of a material being irradiated, provide radiation attenuation, and exclude personnel from its interior during generation of radiation. Included are all x-ray systems designed primarily for the inspection of carry-on baggage at airline, railroad, and bus terminals, and in similar facilities. An x-ray tube used within a shielded part of a building, or x-ray equipment that may temporarily or occasionally incorporate portable shielding, is not considered a cabinet x-ray system.
Automated data acquisition and handling system or "DAHS" means that component of the continuous emission monitoring system, or other emissions monitoring system approved for use under section 11 of this rule, designed to interpret and convert individual output signals from pollutant concentration monitors, flow monitors, diluent gas monitors, and other component parts of the monitoring system to produce a continuous record of the measured parameters in the measurement units required by section 11 of this rule.
911 system means the set of network, database and customer premise equipment (CPE) components required to provide 911 service.
Open video system means an open video system authorized pursuant to 47 U.S.C. § 573 and, for
Composite sample means a combination of individual samples of wastewater taken at 1 hour intervals, for eight (8) hours (or for the duration of discharge, whichever is less), to minimize the effect of variability of the individual samples. Individual samples must be of equal volume. (Example: one (1) liter per hour.)
Computed tomography means the production of a tomogram by the acquisition and computer processing of X-ray transmission data.
Tomographic plane means that geometric plane which is identified as corresponding to the output tomogram.
