Abstract: The present invention provides an efficient and effective method to produce a graphene material by a high shear mechanical process to exfoliate a natural graphite dispersion in a solvent, followed by supercritical exfoliation and drying. The method exfoliates all graphitic flakes into mostly few-layer graphene flakes. This method is more efficient than traditional mechanical exfoliation techniques and completely avoids the need of multiple sampling/centrifugation cycles. The graphene flakes are generally uniform in both size (area) and thickness and show no clumping or aggregation. After drying, this graphene material has high dispersibility in a suitable solvent; the prepared graphene dispersion is stable for at least three months and shows no indication of settling or separation.

Abstract: An optical proximity sensor system to detect a distance to a target object is provided. The optical proximity sensor system includes a laser that generates an emitted optical beam at a linear polarization and an optical cavity system that includes an optical cavity defined by a distance between the laser and the target object. The target object reflects the emitted optical beam to generate a reflected optical beam. A partially reflective mirror diverts a portion of the emitted optical beam and/or the reflected optical beam. A photodetector receives the diverted optical beam and generates a proximity signal that has a frequency that is indicative of the distance to the target object based on the diverted portion of the at least one of the emitted optical beam and the reflected optical beam. A proximity processor calculates the distance to the target object based on the frequency of the proximity signal.

Abstract: The invention is a method for calibrating an intravascular pressure sensor at the point of use. By using data from a secondary pressure measurement device, e.g., an automated aortic pressure monitor, the pressure sensor can be easily calibrated over a range of temperatures and pressures relevant to the patient. Accordingly, an intravascular pressure sensor can be calibrated without undergoing a factory calibration. Additionally, in the event that the calibration is lost, the sensor can be recalibrated.

Abstract: A detection system includes a polarization analyzer that generates one or more null detection values if an object is sensed in a received millimeter wave (MMW) brightness temperature data set. The polarization analyzer analyzes a polarization parameter in the received MMW brightness temperature data set to generate the one or more null detection values. An object detector detects if the object is present based on a comparison of the one or more null detection values to a predetermined threshold. A singular value decomposition (SVD) unit is enabled by the object detector to decompose the MMW brightness temperature data set into a plurality of image layers. Each image layer includes at least one feature of a scene. An identification unit analyzes the plurality of image layers from the SVD unit to determine a shape or a location of the object from the scene.
