| 20110100471 | Drill String Valve and Method - Method and drill string valve for closing a conduit through which a high pressure fluid flows. The drill string valve includes an elongated housing having an inside cavity, a seal element attached to a first end of the elongated housing, the seal element being disposed within the inside cavity such that a flow of liquid through the inside cavity from the first end to a second end of the elongated housing is allowed, a sliding valve disposed within the inside cavity and configured to slide to and from the seal element along the axis such that when the sliding valve contacts the seal element the flow of liquid is suppressed, a biasing cartridge disposed within the inside cavity, between the seal element and the second end of the elongated housing, and configured to apply a first force on the sliding valve such that the sliding valve is contacting the seal element, and a loading mechanism disposed within the inside cavity, between the biasing cartridge and the second end of the elongated housing, and configured to apply a second force on the biasing cartridge. | 05-05-2011 |

| 20110200171 | METHODS AND APPARATUS FOR RENAL NEUROMODULATION VIA STEREOTACTIC RADIOTHERAPY - The present disclosure describes methods and apparatus for renal neuromodulation via stereotactic radiotherapy for the treatment of hypertension, heart failure, chronic kidney disease, diabetes, insulin resistance, metabolic disorder or other ailments. Renal neuromodulation may be achieved by locating renal nerves and then utilizing stereotactic radiotherapy to expose the renal nerves to a radiation dose sufficient to reduce neural activity. A neural location element may be provided for locating target renal nerves, and a stereotactic radiotherapy system may be provided for exposing the located renal nerves to a radiation dose sufficient to reduce the neural activity, with reduced or minimized radiation exposure in adjacent tissue. Renal nerves may be located and targeted at the level of the ganglion and/or at postganglionic positions, as well as at pre-ganglionic positions. | 08-18-2011 |

| 20100005887 | VIBRATION-TYPE MEASURING DEVICE - A vibration-type measuring device includes an exciter arrangement which exerts a time-dependent force with at least one sinusoidal component at an adjustable excitation frequency on a measuring tube, through which a medium can flow, and causes the measuring tube to oscillate. The measuring device includes first and second sensors which are fitted to the measuring tube at different locations. The first and second sensors output first and second measurement signals, respectively. The measuring device includes an evaluation unit which determines a first phase shift between the first and second measurement signals and uses the determined phase shift to determine a measurement variable of the medium. The measuring device includes a phase comparator, which determines a second phase shift between the force and the average value of the first and second measurement signals, and a frequency generator which sets the excitation frequency on the basis of the second phase shift. | 01-14-2010 |
