System for measuring a characteristic of flow of liquid in a vessel of a patient comprising a transducer positioned in a vessel in a patient for supplying ultrasonic energy. The transducer produces a substantially uniform beam which encompasses the vessel. The transducer receives ultrasonic energy back scattered from the red blood cells and provides an electrical output signal. A first moment detector is provided which receives the electrical output from the transducer and provides a first moment signal. Normalization is provided to the output of the first moment detector to provide an electrical output representing a characteristic of the flow of the liquid in the vessel.       Recently Added Patents Web or vapor retarder with tie-strap Standalone, mobile and adjustable stand and tray Switched-capacitor circuit with low signal degradation Smooth bore, chordal transit-time ultrasonic meter and method Logging system and methodology Gasket design for molding large gaskets in a deformed shape Mailpiece inserter including system for controlling friction forces developed on an envelope   Randomly Featured Patents Damper disc assembly Formation of laminated packaging blanks Sulfonation of aromatic compounds Self-aligned planar double-gate transistor structure Fetch and store buffer that enables out-of-order execution of memory instructions in a data processing system Spring plate structure Amplifier with controlled output impedance DNA sequence detection by limited primer extension Electrical connection device and connector Backplane connector © 2006-2008 PatentGenius.
