    摘要： A sensor for measuring a current passing through a load. The sensor has a power transistor having a first terminal connected to substantially constant voltage and a second terminal connected to the load. The sensor can sample a voltage difference with a variable capacitor, and a controller can be configured to cause a variable capacitor in the current sensor to have a capacitance inversely proportional to a resistance of the power transistor, whereby a charge stored on the variable capacitor is proportional to the current passing through the power transistor when the sampling switches are opened. A comparator can compare the current through the power transistor to a known reference current to generate a digital output signal. The sensor can include a power transistor, reference transistor and amplifier connected and configured so as to generate a signal on a reference line having a current of known proportion to the current passing through the load.

    摘要： A method and system for using Threat Imaging Projection (TIP) technology, and the operator testing data that it generates, in order to certify x-ray inspection system operators and thereby assure an acceptable and uniform level of operator performance. In a preferred configuration, the operator views x-ray images of objects on a screening system equipped with TIP technology. When the operator believes that a threat item image appears on the screening system, the operator indicates such via an indicating means. The system is capable of recording, storing and transmitting individual operator performance data relating to proper detections, missed detections, and false alarms, i.e., when an operator indicates that a threat item image appears when no such image actually appears on the screening system. The system preferably contains a library of various threat item images, e.g., guns, bombs, knives, etc., which are classified according to type of threat and difficulty of detection.
