摘要： An electric motor monitoring system is described that comprises an antenna, a data sampling means and a data processing means. The system employs the antenna to detect high frequency arcing events within the electric motor that can thereafter be mapped so as to provide a means for motoring, recording and diagnosing a variety of electric motor operating and fault conditions. The antenna design allows for the suppression of background electrical noise so improving the signal to noise ratio of the detected signals. The same system also provides a facility for optimising the alignment, and monitoring the efficiency of, the electrical and mechanical components of the electric motor.

摘要： A dual path analog-to-digital conversion method and system. The system includes a first and second circuits. The first and second circuits each convert an input analog signal into digital signals at differing sample rates. The circuit having the slower sampling rate aliases frequency components of the input analog signal that are higher than half that sampling rate. Frequency components causing the aliasing in the slower sampling circuit are replicated from the faster sampling circuit at the appropriate amplitude, folded into the aliased frequency, and subtracted from the output of the slower sampling circuit. The outputs of both sampling circuits are then merged. These techniques extend the bandwidth of the slower conversion system without degrading the low-frequency accuracy of the slower conversion system.

摘要： This invention relates to a system that adaptively compensates for subject motion in real-time in an imaging system. An object orientation marker, preferably a retro-grate reflector (RGR), is placed on an organ of interest of a patient during a scan, such as an MRI scan. The marker allows measuring the six degrees of freedom or “pose” required to track motion of the organ of interest. A detector, preferably a camera, observes the marker and continuously extracts its pose. The pose from the camera is sent to the scanner via an RGR processing computer and a scanner control and processing computer, allowing for continuous correction of scan planes and position (in real-time) for motion of the patient. This invention also provides for internal calibration and for co-registration over time of the scanner's and tracking system's reference frames to compensate for drift and other inaccuracies that may arise over time.

摘要： Current MRI technologies require subjects to remain largely motionless for achieving high quality magnetic resonance (MR) scans, typically for 5-10 minutes at a time. However, lying absolutely still inside the tight MR imager (MRI) tunnel is a difficult task, especially for children, very sick patients, or the mentally ill. Even motion ranging less than 1 mm or 1 degree can corrupt a scan. This invention involves a system that adaptively compensates for subject motion in real-time. An object orientation marker, preferably a retro-grate reflector (RGR), is placed on a patients' head or other body organ of interest during MRI. The RGR makes it possible to measure the six degrees of freedom (x, y, and z-translations, and pitch, yaw, and roll), or “pose”, required to track the organ of interest. A camera-based tracking system observes the marker and continuously extracts its pose. The pose from the tracking system is sent to the MR scanner via an interface, allowing for continuous correction of scan planes and position in real-time. The RGR-based motion correction system has significant advantages over other approaches, including faster tracking speed, better stability, automatic calibration, lack of interference with the MR measurement process, improved ease of use, and long-term stability. RGR-based motion tracking can also be used to correct for motion from awake animals, or in conjunction with other in vivo imaging techniques, such as computer tomography, positron emission tomography (PET), etc.
