  • BONE CONDUCTION DEVICE FOR A SINGLE SIDED DEAF RECIPIENT
    Publication number: 20110026748
    Abstract: Methods and systems are provided for determining whether signals to be applied by a bone conduction device would be masked by signals arriving at the good ear of a single sided deaf patient. The bone conduction device then applies stimulation for frequency components of the sound received by the bone conduction device that would not be masked by sound received by the patient's good ear. In applying the stimulation, the bone conduction device may apply a gain to compensate for the head shadow effect. This gain may be determined by inverting at least a portion of a curve for the head shadow effect.

  • BONE CONDUCTION DEVICE FITTING
    Publication number: 20110026721
    Abstract: Methods and systems for fitting a bone conduction device are provided herein. These methods and systems comprise determining a gain to be used by the bone conduction device in providing signals at a particular frequency. In determining the gain, a fitting system may provide a test sound that is modulated between a first signal provided to a speaker and a second audible signal provided to a bone conduction device. The first and second audible signal may comprise properties such that when the two signals are added together they produce a constant amplitude output. In an embodiment, each of the first and second audible signals may comprise substantially identical frequency characteristics and signal amplitudes, such as, for example, equal amplitude sinusoids centered on the particular frequency for the measurement.

  • METHOD OF INSERTING AN ENDOSTEAL ELECTRODE
    Publication number: 20110022147
    Abstract: An implantable tissue-stimulating device comprising an elongate electrode carrier member (11) having a plurality of electrodes thereon. The carrier member (11) is preformed from a resiliently flexible biocompatible silicone and extends from a distal end (12) to a stop member (13). The carrier member (11) is adapted for intracochlear but extraluminar insertion within the cochlea of an implantee. The placement of the carrier member (11) is designed to avoid any breach of the internal ducts of the cochlea (20), such as the scala tympani (24) and scala vestibuli (25) so that the normal hydrodynamic behavior of the cochlea (20) is not affected by any intrusive device. Use of the device in a system for masking or treating the symptoms of tinnitus is also described.

  • Ski Binding Adaptor with Floating Heel Lock
    Publication number: 20110018232
    Abstract: AT ski binding adaptor for alpine ski touring and downhill, including a floating heel lock assembly and multifunctional rotatable locking arms. Ski bindings are mounted on an adaptor mounting plate, channel or beam assembly that pivots at the toe. The heel lock mechanism “floats” on a rail or rails to accommodate ski flex, and includes a multi-position climbing bar or heel riser. The floating heelblock and locking mechanism are interconvertible for different ski modes: in fixed heel-mode—the locking arms act to firmly secure the heel to the ski for aggressive downhill conditions or riding style, and in free heel mode—the locking arms may be configured to support touring and climbing configurations. The ski binding adaptor with floating heel lock mechanism is optionally compatible with a range of alpine ski touring and downhill bindings.

  • Biomolecule analyzing system
    Patent number: 7871571
    Abstract: A biomolecule analyzing system (10) that provides an expeditious, accurate and reliable method for analyzing a biomolecule (150). The system (10) includes two substrates (12,28) each having an inner edge (14,30), an outer edge (16,32) and an inner surfaces (20,36) from where extends a multiplicity of cilia (22).

To the outer edges (16,32) is attached an output tube (106) that is also attached to a sample deposit chamber (120). The tubes (82,106) include a plurality of conductive plates (98) that are applied an electrical charge that causes the biomolecule (150) to traverse through the tubes (82,106). When the biomolecule (150) passes through the cilia (22) signals are produced that are applied to a pair of image capturing devices (40,50).

  • Strain relief device for protection of power cords
    Patent number: 7867015
    Abstract: A strain relief device for protecting a power cord includes a tubular base member defining a lumen adapted to accommodate a power cord. The lumen includes a trailing lumen, a leading lumen, and an annular recess formed between the trailing and leading lumens. The leading lumen has flat, tapered sidewalls. A tapered cylindrical plug is sized to snugly fit within the leading lumen and has a protruding annular rim at its narrow end. The diameter of the protruding annular rim is about equal to the diameter of the annular recess so that the rim snaps into the recess when the plug is inserted into the leading lumen. The plug is disposed in encircling relation to the power cord prior to insertion of the plug. Pulling on the power cord increases the compression of the plug about the cord due to the common taper of the plug and the leading lumen.

  • METHOD FOR TREATING RENAL CELL CARCINOMA USING GLYCOGENOLYSIS INHIBITORS
    Publication number: 20100166701
    Abstract: Renal cell carcinoma (RCC) exhibits unpredictable behavior, high recurrence rate, insensitivity to Positron-Emission Tomography (PET), and poor response to existing cancer treatments such as chemotherapy. Inhibition of glycogenolysis can restrict RCC tumor growth and increase its susceptibility to other treatments, in particular, those that compromise access to nutrient, such as anti-angiogenenic compounds. This can also increase uptake of glucose derivatives and thus increase sensitivity of PET. Reduction of glycogen stores within RCC through treatment with iron-salts can also reduce tumor growth rate through reducing activation of the hypoxia pathway. Thus, synergistic treatment of RCC with glycogenolysis inhibitors or inhibitors of glycogenosis, and/or in combination with anti-angiogenic compounds, can increase sensitivity of tumor detection, slow tumor formation and/or metastasis.

  • Milestone synchronization in broadcast multimedia streams
    Patent number: 7668914
    Abstract: A server at the edge of a broadband network distributes multimedia content streams to clients, while ensuring that the first data delivered to each client is key data (milestones) needed for correctly decoding the stream content. This is obtained by buffering the packets in the incoming stream and transmitting the packets from the buffer in an outgoing stream, starting with the most recent milestone placed in the buffer before a request to join the respective incoming stream is received. As the writing to and reading from the buffer are performed at different rates, the incoming and outgoing streams are eventually synchronized, at which point the client may be switched to receive the incoming stream directly.
