摘要： A passenger scanning system includes a passenger screening area configured for a person to enter and a shield surrounding at least a portion of the passenger screening area. The shield is configured to reduce a radio frequency interference within the passenger screening area. The passenger scanning system also includes one or more sensors positioned in the passenger screening area at a height configured to be proximate one or more of an abdominal region, a groin region, and a pelvic region of the entered person. The sensors are configured to generate a signal in response to a target substance located in the one or more of the abdominal region, the groin region, and the pelvic region.

摘要： A method of operating a screening system includes applying an electromagnetic field to a subject in a region at least partially enclosed by electromagnetic shielding, and measuring an output from a sensor. The output is representative of an interaction of the electromagnetic field and the subject. A trace vapor is collected from the subject within the region, and the trace vapor is identified. Based on the measured sensor output and the identified trace vapor, whether a target material is associated with the subject is determined.

摘要： A device for detecting random objects that are being carried inside a container includes an excitation coil and a sensing coil with a gap therebetween. When the construction of the container includes a conducting loop, the container is positioned on a path between the two coils, with the plane of the loop substantially perpendicular to the path. The excitation coil is then activated to generate a magnetic field that is directed along the path. This magnetic field has both a sinusoidal component and a cosinusoidal component. Importantly, the cosinusoidal component is adjusted to match a characteristic dimension of the loop, to thereby cause zero mutual inductance with the loop in the magnetic field. On the other hand, conducting objects inside the loop will cause inductance perturbations in the magnetic field which can be detected to establish the presence of the objects in the container.

摘要： A method for maintaining encoded coherence for a remotely positioned MRI device is accomplished in groups of pulses. Each group includes four sequences of pulses and each sequence includes a tilting phase, an encoding phase and a recording phase. Specifically, each sequence begins with a 90.degree. tilting pulse. The encoding phase, which follows, is characterized by a time interval between refocusing 180.degree. pulses which is of sufficient duration to permit effective encoding of the material to be imaged. On the other hand, the recording phase, which follows the encoding phase, is characterized by a time interval between refocusing 180.degree. pulses which is shorter in duration in order to maintain encoded coherence during imaging. Within any group of pulses, there are four individually different sequences which result by shifting the phases of the refocusing pulses from sequence to sequence to provide 180.degree..sub..+-.x and 180.degree..sub..+-.y refocusing pulses.

摘要： A radio frequency power amplifier including control electronics for providing control signals for timing of the power amplifier. A first group of the drivers are coupled to the control electronics and a second group of drivers are coupled to the control electronics. The first group of drivers operate in response to the control signals to generate first drive signals and the second group of drivers operate in response to the control signals to generate second drive signals with a phase difference of 180° relative to the first drive signals. A first group of switches energize a first group of primary windings in response to the first drive signals and a second group of switches energize a second group of primary windings in response to the second drive signals. An output summing transformer has a plurality of ferrite cores, the first group of primary windings and the second group of primary windings passing through the ferrite cores. A secondary output winding for connection with a load passes through the ferrite cores of the output summing transformer.
