Sensor having electrode for determining the rate of flow of a fluid
InactiveUS6801041B2Accurate measurementMicrobiological testing/measurementVolume/mass flow by electric/magnetic effectsTarget analysisAnalyte
Sensors that are capable measuring the rate of flow of a fluid that passes over the electrodes of the sensor. In these sensors, an electrode, designated the flow rate-determining electrode, is used in conjunction with the conventional electrodes, e.g., the working electrode, the reference electrode, and the counter electrode, to determine the rate of flow of the fluid. In one aspect, this invention provides a sensor for measuring the concentration of an analyte in a sample of fluid when the sample flows continuously over the electrodes of the sensor, especially when the rate of flow of the sample is relatively low. In another aspect, this invention provides a method for measuring the concentration of an analyte in a sample of fluid, wherein the rate of flow of the sample varies during the period of time that the sensor is in place. In a preferred embodiment, the sensor employs four electrodes, namely, a working electrode, a reference electrode, a counter electrode, and a flow rate-determining electrode. Alternatively, a single electrode that performs both the function of the reference electrode and the function of the counter electrode can replace the reference electrode and the counter electrode. In addition, a dummy electrode or a blank electrode can be used to compensate for interference from electrochemically active species. The reagent(s) specific to the analyte of interest is required to be deposited on the working electrode.

The device thereby compensates for the first signal based on the extracted difference signal. A display unit in the device scrolls an image based on the compensated signal. This prevents a failure caused by the temperature drift of the angular velocity sensor.

Motion tracking system for real time adaptive imaging and spectroscopy
ActiveUS20070280508A1Improve performanceImprove accuracyImage analysisCharacter and pattern recognitionAdaptive imagingUsability
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.

Dynamic wake prediction and visualization with uncertainty analysis
InactiveUS6963291B2Improve accuracySimple wake modelAircraft componentsAnalogue computers for vehiclesNo-fly zoneVisual perception
A dynamic wake avoidance system utilizes aircraft and atmospheric parameters readily available in flight to model and predict airborne wake vortices in real time. A novel combination of algorithms allows for a relatively simple yet robust wake model to be constructed based on information extracted from a broadcast. The system predicts the location and movement of the wake based on the nominal wake model and correspondingly performs an uncertainty analysis on the wake model to determine a wake hazard zone (no fly zone), which comprises a plurality of “wake planes,” each moving independently from another. The system selectively adjusts dimensions of each wake plane to minimize spatial and temporal uncertainty, thereby ensuring that the actual wake is within the wake hazard zone. The predicted wake hazard zone is communicated in real time directly to a user via a realistic visual representation. In an example, the wake hazard zone is visualized on a 3-D flight deck display to enable a pilot to visualize or “see” a neighboring aircraft as well as its wake. The system substantially enhances the pilot's situational awareness and allows for a further safe decrease in spacing, which could alleviate airport and airspace congestion.
