A method of calculating blood flow in an organ of a subject using output radiofrequency signals transmitted to the organ and input radiofrequency signals received from the organ, the method comprises determining a phase shift of the input radiofrequency signals relative to the output radiofrequency signals and using the phase shift to calculate the blood flow in the organ.

System, method and apparatus for measuring blood flow and blood volume

A system for measuring blood flow in an organ of a subject, particularly useful for non-invasive cardiac output monitoring (N.I.C.O.M.&#x2122;), the system comprises: a radiofrequency generator for generating output radiofrequency signals; a plurality of electrodes, designed to be connectable to the skin of the subject, the electrodes being for transmitting the output radiofrequency signals to the organ and for sensing input radiofrequency signals of the organ. The system further comprises a mixer, electrically communicating with the radiofrequency generator and at least a portion of the plurality of electrodes, for mixing the output radiofrequency signals and the input radiofrequency signals, so as to provide a mixed radiofrequency signal being indicative of the blood flow. The system further comprises electronic circuitry, constructed and designed to filter out a portion of the mixed radiofrequency signal so as to substantially increase a signal-to-noise ratio of a remaining portion of the mixed radiofrequency signal.

A multispindle lathe comprising a rigid, stationary frame, a drum mounted for rotation on the frame, indexing means for indexing the drum relative to the frame about its axis of rotation, a plurality of driven spindles carried by the drum with their axes parallel to and spaced about the axis of rotation of the drum, each spindle being equipped to carry a workpiece, and, a plurality of tool mechanisms carried by the frame and disposed around the axis of the drum for machining workpieces carried by the main spindles, a secondary spindle facing towards said main spindles and having its axis of rotation parallel to the axes of rotation of said main spindles, said secondary spindle being equipped to grip the portion of a workpiece protruding from one of the main spindles, a two axis slide system carried by the frame of the lathe and supporting said secondary spindle whereby said secondary spindle can be moved in directions axially towards and away from, and transversely with respect to the axes of the main spindles, drive means for rotating said secondary spindle and a tool support for carrying one or more tools for machining a workpiece carried by said secondary spindle, said support being carried by the frame spaced from the axis of said drum.
