Abstract: A system suitable for reducing static or slow moving echoes from acoustic boundaries in a system such as pipe walls, blood vessels, tissue structures so that an image from flowing or time varying media such as water, oil, blood etc may be imaged more clearly, the system including an analog-to-digital converter for digitizing a received analog signal from a detector, means for digitally separating static or slow moving components of the digital signal, a digital-to-analog converter to provide an analog version of the separated static or slow moving components of the signal, and a subtractor to subtract the analog version of the static or the slow moving components of the signal from an analog signal received from a detector to produce an analog signal corresponding to the remaining flow components of the signal.

Abstract: A torsional sensor including a high-pressure sealing mechanism for sensing at least one parameter of a high-pressure fluid. The torsional sensor includes a torsional portion including a torsional rod sensor, a reference portion coupled to the torsional portion and including a transducer device and a high-pressure sealing mechanism coupled to the reference portion and the torsional portion and in sealing arrangement therewith. The high-pressure sealing mechanism is configured to provide for sealing therein the transducer device and allow for protrusion therethrough of a torsional rod sensor. At least a portion of the torsional sensor is mountable for immersion in the high-pressure fluid and operable to propagate a torsional wave that interacts with the high-pressure fluid along the at least portion of the torsional sensor so as to affect propagation of the torsional wave in a manner dependent on the at least one parameter of the high-pressure fluid.

Abstract: The present invention relates to health care, and more particularly to a dynamic and mobile platform for providing comprehensive health care record and workflow management, including management of medical billing, that can be configured for healthcare professionals who do not necessarily practice from a single location, and may practice frequently from locations outside of their primary practice location. The technology provides a health care data capture, analysis and user interface solution that simplifies and expedites the billing procedure for healthcare professionals. Additionally, the technology described herein supports healthcare professionals who may work as a team, and need to communicate and collaborate with each other while rendering their services.

Abstract: This is an improved latch for a collapsible stringed musical instrument providing for a two step assembly or disassembly and combining all operations into a single lever, knob, or cam. A snap action catch holds the instrument in the intermediate position, resisting the stings tension, allowing for a second step to tighten or loosen the neck to the body of the instrument without de-tuning the instrument's strings.
