  • Patent number: 8664503
    Abstract: The invention provides an apparatus and method for notating music for a harmonica. The apparatus incorporates a vertical staff in which vertical lines or tracks represent individual notes, the length of which represents duration of the note, and the horizontal location represents the physical location of the corresponding hole in a harmonica. The invention provides a rapid means of learning to play a harmonica and, for experienced players, provides a means for sight reading a new piece of music. The invention further provides ways of representing the dynamics of both pitch and loudness and a convenient way to manually transcribe musical selection for archival purposes.

  • Publication number: 20120130255
    Abstract: Medical device or instrument for diagnosing pressure ulcers using optical reflectance spectroscopy. The device may comprise a tip and a controller. The tip is pressed against the skin of the patient and collects the optical reflectance data. The controller processes the data to determine whether there exists a pressure ulcer and, if there is one, its depth. The tip may also include a pressure sensor for sensing the pressure at which the tip is applied to the patient's skin.

  • Publication number: 20110237863
    Abstract: A magnetically-levitated blood pump with an optimization method that enables miniaturization and supercritical operation. The blood pump includes an optimized annular blood gap that increases blood flow and also provides a reduction in bearing stiffness among the permanent magnet bearings. Sensors are configured and placed optimally to provide space savings for the motor and magnet sections of the blood pump. Rotor mass is increased by providing permanent magnet placement deep within the rotor enabled by a draw rod configuration.

  • Patent number: 7338521
    Abstract: A low profile pump inlet for an implantable blood pump is disclosed. The low profile pump inlet has an inflow diffuser for attachment to a conduit bearing an inflow of a fluid such as blood and an outflow orifice in fluid connection with the diffuser. The outflow orifice is configured to direct the fluid from the diffuser into a pump such as an implantable blood pump. The low profile pump inlet helps to suppress the effects of upstream pipe bends on the blood traveling through the inlet. The inlet thus provides a flow having a substantially uniform velocity profile into the blood pump.

  • Patent number: 6635814
    Abstract: Harmonica structures designed for enhancing harmonica play are disclosed. In one aspect, a reed comb is provided with a common bridge having reeds formed integrally therewith. The reed plate has a plurality of reed slots formed therein and is adapted to receive the reeds of the reed comb into corresponding slots formed in the reed plate. A stepped portion formed in the reed plate is adapted to receive a reed of the reed comb therein to permit substantial encasement of the reed within the reed slot. A key benefit of this arrangement is to resist leakage of air between the reed plate and the flanks of the reed during harmonica play. The reed plate can also include a first stepped portion upon which the roots of the reeds are positioned and a second stepped portion positioned adjacent to the tips of the reeds. Other structures are disclosed that include a radiused surface formed on a portion of the reed or on the surface of the reed slot in which the reed is positioned.
