摘要： A microprocessor controlled security tag and accompanying security system is described. The tag generally includes a housing having external contacts to interface with elongated contacts on a connecting band. The band forms a complex impedance circuit with a patient's limb that allows detection features such as removal and band compromise. A microprocessor and related circuitry as well as a transmitter and receivers are enclosed in the housing. The tag is adapted to communicate inductively with an activator/deactivator unit as well as a tag programmer that updates and changes tag features in the tag firmware. The overall system further includes a hub to receive the data from a plurality of tags in the system. The tag can also communicate with a phased multiple antenna that sends signals to the tag.

摘要： A filter system and associated method efficiently suppress noise and improve edge definition in a digitized image. The filter system has a statistical noise determination mechanism which initially determines a baseline noise level of the image. The baseline noise level is used by a filter(s) which operates upon the image data at a later time. After the statistical noise determination mechanism, the filter system generally comprises three independent system branches. Each branch has one or more filters. Each filter is configured to receive an image data array and to modify the image data array to derive a respective modified image data array. Further, each branch has a gain control mechanism adapted to modify a respective modified image data array based upon a gain factor. Finally, an assimilation mechanism combines the modified image data arrays from the gain control mechanisms to derive an improved image data array. Optionally, a rescale mechanism may be employed for adjusting intensities corresponding with pixel values of the improved image data array so that the intensities reside within a predefined range, without degradation in image resolution.

摘要： Blood flow in human limbs is measured non-invasively by a nuclear magnetic resonance blood flowmeter which includes a pair of polarizing magnets whose fields are stabilized by electromagnets in each pole piece that are energized in accordance with the magnetic flux of the magnets as sensed by a Hall effect sensor. Blood molecules are either self-tagged by the polarizing field or are separately tagged by a tag coil whose field is orthogonal to the polarizing field. Once tagged, the variation in the magnetic moment of the molecule due to the tagging is detected by the variation in voltage in the receiver coil which is located orthogonally to the transmitter coil so as to reduce crosscoupling therebetween. Two sets of scanner coils, one located parallel to and the other orthogonal to the polarizing field directions, respectively, are energized to create a pair of intersecting null planes which act to cancel nuclear magnetic resonance response detected by the receiver everywhere but along the line where the two null planes intersect. By varying the current in the scanner coils, the resulting line of intersection of the null planes can be moved in two dimensions so as to scan the limb thereby allowing blood flow measurement at various locations within the limb.

摘要： An NMR blood flowmeter applies a continuous transverse excitation signal and a constant, homogeneous polarizing magnetic field to blood flowing through an active region. The polarizing magnetic field is contoured at opposite boundaries of this active region, and by switching these contours and collecting the resulting NMR signals, data is obtained from which the various components of blood flow may be calculated.
