Abstract: A cytometer having two or more chambers or regions in a containment structure of sheathing fluid that may be used to provide hydrodynamic focusing of another fluid having particles to be observed. The latter fluid may be a core stream which may have its lateral position in a flow or measurement channel affected by control of at least one of the parameters of the several segments of the sheathing fluid. The lateral position of the core stream may be aligned with a light source and detector for a count and observation of the particles. Electrical signals from the detector may be fed back to a processor which may control one or more parameters of the sheathing fluid in the various chambers or regions via pumps, valves, and flow and pressure sensors. This control of parameters may provide for the positioning of the core stream. This cytometer may be miniaturized.

Abstract: In accordance with the principles of the invention, a lamellar grating interferometer breaks the radiation down into its wavelength components. The two sets of teeth of the grating are moved relative to each other. The spectral output of the interferometer is focused on an array of detectors and data is stored for a large number of positions of the grating teeth. The collected data is then Fourier transformed to recover the spectrum of the radiation.

Abstract: A probabilistic medical billing system and method using contextual data and inferential logic for use in screening accuracy of medical bill coding and for presenting results as probabilities or predictions of correctness. The probabilistic medical billing system and method is accomplished using the contextual information contained in a care givers' patient encounter notes, a set of rules and keywords, and an inferential, logic, engine based on Bayesian mathematics or similar disciplines. The inventive device includes an input device to capture care giver's encounter notes or other information, a lexical engine that extracts information while preserving the contextual order of the information, a relational database that contains keywords, phrases and rules and a statistical/probabilistic engine that uses Bayesian mathematics or similar disciplines to create the output. The lexical engine parses a document into words and is capable of extracting keywords or phrases as listed or defined in a master list.

Abstract: An optical element for conveying scattered and image light to several detectors. The optical element may have the properties of a diffractive beam splitter and imaging lens. The detected light may be from an illuminated target. Further, there may be an optical element for conveying scattered light from a target via several zones to specific detectors, respectively. The latter optical element may include a multiple annular zone diffractive structure on a hybrid lens.

Abstract: A system for ligating a uterine artery in a patient generally includes a suture transfer tool, suture transfer darts, and one or more sutures. The suture transfer tool includes an upper jaw that is pivotally joined to a lower jaw. The lower jaw of the tool includes a number of suture capturing pins. The suture transfer darts are configured to be tissue piercing and are positionable within the suture capturing pins. Each end of the suture is connected to a suture transfer dart. When operating the tool, the suture transfer darts pierce through the tissue to either side of a patient's cardinal ligament, which contains the uterine artery, and simultaneously present an end of the suture to either side of the cardinal ligament. As such, the suture is in an open loop configuration about the cardinal ligament and can be tied tight to the ligament to occlude the uterine artery.

Abstract: This disclosure concerns methods for transmitting a signal in an optical system. In one example, the method begins when an optical signal is generated. Then, the optical signal is manipulated such that the optical signal defines a substantially annular intensity profile, where power of the optical signal varies in the intensity profile. Finally, the optical signal is launched into an input face of an optical fiber such that a predetermined part of the intensity profile of the optical signal is located proximate an optical axis associated with the optical fiber.
