  • Patent number: 7317390
    Abstract: An advanced technology screening checkpoint system includes a baggage screening zone, a passenger screening zone, and a secondary screening zone. The baggage screening zone may include an explosives scanning system and an imaging system, while the passenger screening zone may include an explosives detection portal and a self-divestment portal to show passengers what to divest prior to screening by a high sensitivity metal detection portal. In some implementations, a secondary screening zone includes a sealed-bottle scanning system, an enhanced explosives detection system, a weapons search routine, and a body scanning system. Centralized monitoring of screening results for individual detection and screening systems of the baggage, passenger, and secondary screening zones may be provided by a combined user interface (CUI).

  • Publication number: 20060138878
    Abstract: An impeller and at least a portion of a cooperating peripheral volute may be integrated into, and preferably are integrally injection molded with, concentric outer rotor and inner stator assemblies, respectively, to achieve a low profile precision impeller mechanism based on an improved brushless d.c. motor with low length (L) to diameter (D) ratio and suitable for use in a variety of other applications. In one practical embodiment of such a motor, a rotating cap has an inner circumference which is molded about an outer ferromagnetic back ring that in turn supports a permanently magnetized ring shaped rotor magnet having a number of poles of alternating polarity defined about its inner circumference and separated by a relatively small cylindrical air gap from the outwardly projecting radially oriented selectively magnetized poles of a fixed stator assembly. In one exemplary embodiment, the rotor may have 8 poles and the stator may have 9 poles.

  • Patent number: 7047059
    Abstract: A probe instrument using room-temperature sensor(s) that can measure variations in magnetic susceptibilities. The instrument has sufficient resolution to monitor paramagnetic materials in a human body, such as iron in a human liver, by noninvasively examining patients with iron-overload diseases. The instrument includes room temperature magnetic sensors, and detects the sample, that is, the tissue response to an alternating current field applied by an applied field coil. The applied field coil dimensions are chosen so that the applied field is optimized for maximum response from the liver while minimizing the effects due to the overlying abdominal tissue and at the same time not unduly increasing the sensitivity of the instrument to the lung. To overcome variations in the sensor output due to fluctuations in the applied field, change in the ambient temperature and mechanical relaxation of the instrument, the sensor-sample distance is modulated.

  • Patent number: 6977503
    Abstract: A magnetic resonance imaging apparatus and method having a magnet assembly, which provides substantially flat surfaces of constant magnetic field outside the assembly and a set of magnetic field gradients. One-, two-, and three-dimensional images are rendered. The static magnetic field is virtually uniform within horizontal degrees of freedom and decreases monotonically in a direction away from the surface. An RF probe, for example, a coil, located adjacent the surface, produces a field substantially perpendicular to the static magnetic field. A magnetic field gradient is set to horizontally scan a given level within the sensitive volume. Received magnetic resonance signals are detected by the coil for a depth corresponding to the excitation frequency. As the tuning and excitation frequency is switched to lower values, signals are generated for layers progressively farther from the surface. The RF probe is automatically tuned.

  • Patent number: 6965677
    Abstract: The apparatus is a cross fader with a slide assembly which slidingly traverses a path defined by two parallel guide rods which pass through a partially open channels in the slider of the slide assembly. Tension plates are secured by self-tapping screws within recesses laterally adjacent to open portions of at least one of the channels. The tension plates are urged radially against the guide plates, so that the tighter the screws are secured, the tighter the tension plates are urged against the guide rods and the more frictional resistance is generated when the user moves the slider.

  • Patent number: 6965792
    Abstract: Methods and apparatus for minimizing the effects of temperature drift in a magnetic susceptibility measurement instrument, such as an instrument used in pre-MRI screening for the presence of ferromagnetic foreign bodies. The magnetic field source and magnetic sensors can be combined into a single, rigid unit. The stability and sensitivity required in high quality magnetic susceptibility measurements can be achieved through symmetrical design of the source-sensor unit, minimization of thermal stresses, minimization of temperature variations, use of materials with low thermal expansion coefficients, or through appropriate combinations thereof. Use of patient eye movement where an eye is being screened, use of a water bag between the patient and the instrument, or use of telemedicine to facilitate performance of the necessary computations can also be incorporated.
