摘要： An apparatus and method for detecting the location of subsurface markers in a formation proximate to a borehole. The apparatus includes marker detectors in a housing having at least two housing sections attached in an initial orientation. The distance between the detectors is measured under controlled conditions with a calibration bar. The initial attached orientation between the housing sections is identified with a calibrator, and deviations from the initial attached orientation are identified by the calibrator after the housing sections are detached and reattached. The calibrator permits well site corrections to be made to the housing sections without recalibration. Gauges permit corrections for temperature and pressure fluctuations, and the corrected distances between the housing detectors is computed. Detectors in the housing generate signals when each detector is proximate to a marker in the formation, and such signals can be processed to identify the elevation of a marker in the borehole, or the distance between markers in the borehole, to determine formation compaction or settlement. In an apparatus having two detectors separated by a spacer, flexible retainers can be positioned between each detector and the spacer to permit thermal expansion or contraction of the detectors relative to the spacer.

摘要： Aspects of the invention are directed to advanced monitoring and control of medium voltage therapy (MVT) in implantable and external devices. Apparatus and methods are disclosed that facilitate dynamic adjustment of MVT parameter values in response to new and changing circumstances such as the patient's condition before, during, and after administration of MVT. Administration of MVT is automatically and dynamically adjusted to achieve specific treatment or life-support objectives, such as prolongation of the body's ability to endure and respond to MVT, specifically addressing the type of arrhythmia or other pathologic state of the patient with targeted treatment, a tiered-intensity MVT treatment strategy, and supporting patients in non life-critical conditions where the heart may nevertheless benefit from a certain level of assistance.

摘要： Systems and methods for providing multi-homed tandem access in a communication system are disclosed. The disclosure may include a private packet network backbone exchange (PPNBE) in connection with a set of access tandems and with a call destination such as an end-user or a communications service. A set of LRNs may be homed across the set of access tandems, with each of the set of LRNs mapped to one or more TNs corresponding to the call destination. An originating party may use any of the TNs to reach the call destination. A plurality of originating calls each including one of the TNs may be received at the PPNBE from any of the access tandems and routed to the call destination. Thus, the present disclosure provides greater call capacity than available access tandem architectures as well as optimizes a maximum number of call paths to a particular call destination.

摘要： A method and apparatus for delivering a truncated damped sinusoidal external defibrillation waveform which, when applied through a plurality of electrodes positioned on a patient's torso will produce a desired response in the patient's cardiac cell membranes is provided. The method includes the steps monitoring a patient-dependent electrical parameter and determining a duration based on the parameter determined. A first set of charge storage capacitors is then charged. A first truncating switch is then closed to discharge the first set of capacitors. Then, after the duration period that was calculated has expired the switch is opened to truncate the waveform. The computation of discharge duration is made as a function of the desired cardiac membrane response function, a patient model and a defibrillator circuit model.
