Abstract: The present invention provides a method of controlling a wastewater treatment plant. The plant comprises at least one process tank and an aeration structure configured for aeration of the at least one process tank. The method comprises alternating steps of increasing aeration to the at least one process tank when a first event occurs, wherein the first event is one of when a first threshold value of a first tank parameter is reached and when a first predetermined time period has expired, and decreasing aeration to the at least one process tank when a second event occurs, wherein the second event is one of when a second threshold value of a second tank parameter is reached and when a second predetermined time period has expired.

Abstract: A Driver Risk Assessment System and Method Having Calibrating Automatic Event Scoring is disclosed. The system and method provide robust and reliable event scoring and reporting, while also optimizing data transmission bandwidth. The system includes onboard vehicular driving event detectors that record data related to detected driving events and selectively store or transfer data related to said detected driving events. If elected, the onboard vehicular system will score a detected driving event, compare the local score to historical values previously stored within the onboard system, and upload selective data or data types to a remote server or user if the system concludes that a serious driving event has occurred. Importantly, the onboard event scoring system, if enabled, will continuously evolve and improve in its reliability by being periodically re-calibrated with the ongoing reliability results of manual human review of automated predictive event reports.

Abstract: A multimodality imaging phantom is disclosed which is useful for calibrating devices for imaging vascular conduits. The phantom is compatible with X-ray, ultrasound and magnetic resonance imaging techniques. It allows testing, calibration, and inter-modality comparative study of imaging devices, in static or dynamic flow conditions. It also provides a geometric reference for evaluation of accuracy of imaging devices. The tissue-mimicking material is preferably an agar-based solidified gel. A vessel of known desired geometry runs throughout the gel and is connected to an inlet and outlet at its extremities for generating a flow circulation in the vessel. Said phantom also contains fiducial markers detectable in the above-mentioned modalities. The markers are preferably made of glass and are embedded in a layer of agar gel containing a fat component.

Abstract: A improvement to a snow scooter having a longitudinal axis, a stand-on area, a back portion rearward of the stand-on area, a handle, and at least one gliding surface having a flat portion defining a plane. The improvement includes a brake plate, operable with a foot of a rider, mounted at an aft end of the scooter. The brake plate is oriented transverse to the longitudinal axis, and is affixed to the scooter with a pivot transverse to the longitudinal axis in the back portion rearward of the stand-on area. Further, the brake plate is retained above the plane of the flat portion of the gliding surface by a spring until depressed with a force that overcomes the spring allowing the brake plate to pivot downwardly to protrude below the plane of the flat portion of the gliding surface.

Abstract: A multimodality imaging phantom is disclosed in the present invention. This multimodality imaging phantom is particularly useful for calibrating devices for imaging vascular conduits. The phantom is compatible with X-ray, ultrasound and magnetic resonance imaging techniques. It allows testing, calibration, and inter-modality comparative study of imaging devices, in static or dynamic flow conditions. It also provides a geometric reference for evaluation of accuracy of imaging devices. The tissue-mimicking material is preferably an agar-based solidified gel. A vessel of known desired geometry runs throughout the gel and is connected to an inlet and outlet at its extremities for generating a flow circulation in the vessel. Using a lost-material casting technique, complex realistic geometry (including 3D configurations with no symmetry axis or plane) of normal or diseased vessel can be modeled. Said phantom also contains fiducial markers detectable in the above-mentioned modalities.

Abstract: The method of estimating systolic and mean pulmonary artery pressures of a patient, comprising the steps of (a) producing an electric signal xs(t) representative of heart sounds of the patient; (b) extracting second heart sound S2(t) from the signal produced in step (a); (c) extracting pulmonary and aortic components P2(t) and A2(t) from S2(t); (d) extracting a signal representative of mean cardiac interval; (e) correlating the pulmonary and aortic components P2(t) and A2(t) to obtain a cross correlation function; (f) measuring a splitting interval of the cross correlation function obtained in step (e); (g) producing a normalized splitting interval; and (h) estimating the systolic and mean pulmonary artery pressures by means of predetermined regressive functions. The present invention also relates to an apparatus for estimating systolic and mean pulmonary artery pressures of a patient.

Abstract: To compensate for the poor signal-to-noise ratio when transforming a patient tracheal sound signal into a respiration flow signal, the transformed signal is used when the sound signal is above a threshold, and interpolated values are used when the sound signal is below the threshold. A volume of breath signal is reliably obtained. Respiration start/stop is detected either by analyzing the sound signal or by physical measurement of the patient. A wearable device incorporating the sound signal processing method can provide an immediate indication or alarm when the volume of breath signal indicates a condition requiring medical attention.

Abstract: The sight comprises a support adapted for mounting onto an instrument to be aimed at a target, an optical device mounted onto the support for creating an image including a first sighting mark at a first finite distance with respect to the optical device, and a device mounted on to the support for providing a second sighting mark at a finite distance with respect to the first sighting mark. The instrument is aimed at the target by aligning the sighting marks. Since at least the first sighting mark is an image, its position can be chosen to improve the accuracy of aiming by alignment of the marks without having to physically accommodate the first mark.
