Abstract: Exemplified methods and systems facilitate presentation of data derived from measurements of the heart in a non-invasive procedure (e.g., via phase space tomography analysis). In particular, the exemplified methods and systems facilitate presentation of such measurements in a graphical user interface, or “GUI” (e.g., associated with a healthcare provider web portal to be used by physicians, researchers, or patients, and etc.) and/or in a report for diagnosis of heart pathologies and disease. The presentation facilitates a unified and intuitive visualization that includes three-dimensional visualizations and two-dimensional visualizations that are concurrently presented within a single interactive interface and/or report.

Abstract: Various embodiments of the present invention provide methods, apparatus, systems, computing devices, computing entities, and/or the like for performing anomaly detection operations. Certain embodiments of the present invention utilize systems, methods, and computer program products that perform anomaly detection operations by using a three-tiered unsupervised anomaly detection machine learning framework to perform high-volume anomaly detection and via utilizing a first tier anomaly detection tier that uses a randomized partitioning anomaly detection machine learning model (e.g., an isolation forest anomaly detection machine learning model), a second tier anomaly detection tier that uses a rule-based partitioning anomaly detection model, and a third tier anomaly detection tier that uses a clustering machine learning model and intra-cluster inferences performed based at least in part on cluster distribution ratios and/or per-cluster anomaly designations.

Abstract: The present invention relates to patient monitoring methods and patient monitoring systems for monitoring at least one aspect of a subject patient's motion alone or with one or more additional patient subject related measurements. The patient monitoring method and system can be a useful clinical tool in the monitoring of patients, and in particular, although not exclusively orthopaedic patients, both pre-treatment and post treatment.

Abstract: A driver supplying a total current to a load has a plurality (n) of driver stages (ST1 . . . STn). One stage is a master stage. Each driver stage has a switching device (Q) and an inductor (L) connected in series between the switching device and the output of the driver stage. The switching devices are turned ON in sequence with one another, during a cycle time (Tc) which is determined by sensing current through the inductor (L1) in the master stage. When the switching device is turned ON current through the inductor rises, when the inductor current reaches the value of a demanded current the switch is turned OFF, and after the switch is turned OFF the inductor continues to supply (output) current to the load with a current which ramps down. A rectifying device (D) connected between the inductor and the supply line allows current to continue to flow in the inductor and be supplied to the load after the switch is turned OFF.

Abstract: A paint formulation which contains specific enzymes which remain inactive in an applied surface coating of the paint formulation until specifically activated by a subsequently-applied applicator solution to facilitate removal of the surface coating. When the applicator is applied to the surface coating, the enzymes catalyse the hydrolysis of the binder in the paint or surface coating, e.g. by cleaving the ester bonds in the 1 and 3 positions of the triglyceride molecules. This allows for easy and rapid removal of the coating without damaging or affecting the underlying surface. The invention is useful either for general purpose paint removal, or for the cleaning up or removal of unwanted graffiti.

Abstract: A capacitor is connected to the output of a multiphase power converter, and a current-driven device (e.g., LED or laser diode) is also connected to the power converter output. A solid state switch (FET or IGBT) is connected in series with the current-driven device. Means are provided for sensing current through the current-driven device. An error amplifier compares sensed current through the current-driven device with a current level demand signal and controls the output of the power converter. Means are provided for turning the switch on and off and may be (i) a fast comparator receiving a voltage reference signal at one input and the current level demand signal at another input, and outputting the switch on/off signal to the switch or (ii) an externally-generated logic signal provided directly to the switch.

Abstract: A centralizer (1) is provided with a hollow body (2) and a plurality of equally spaced arms (4). The arms (4) extend in the form of cup handles from the hollow body (2). Each arm (4) has a variable cross-section along its length with the cross-section becoming increasingly ovoid towards one end of the arm (4).

Abstract: Solid composition including a gum material and an tea tree oil and optionally another essential oil wherein the solid composition releases vapor containing the essential oil when exposed to an effective flow of gas. A method of diffusing tea tree oil into the atmosphere and a method of disinfecting air conditioning systems are also provided.
