20120172655 | IMPELLER HOUSING FOR PERCUTANEOUS HEART PUMP - Disclosed herein are heart pumps that include a catheter assembly and that can be applied percutaneously. Some embodiments include a locking device that prevents components of the catheter assembly from being separated when in use. The catheter assembly can include an expandable tip. In some embodiments, the catheter assembly includes a housing having a wall structure, a portion of which can have a bulbuous shape or can be deformable. In other embodiments, the housing can be configured to reduce fluttering or deflection of the housing and/or to maintain a gap between the housing and an impeller blade disposed therein. | 07-05-2012 |
20120178986 | PERCUTANEOUS HEART PUMP - Disclosed herein are heart pumps that can include a catheter body and an impeller coupled with a distal end of the catheter body. The impeller can include a tip that is resealable or that includes a resealable member. The heart pump can also include a diffuser disposed between the distal end of the catheter body and the impeller, wherein the diffuser includes a flow directing surface. | 07-12-2012 |

20110106466 | METHODS AND DEVICES FOR MONITORING THE INTEGRITY OF A FLUID CONNECTION - A surveillance device monitors the integrity of a fluid connection between first and second fluid containing systems based on at least one time-dependent measurement signal from a pressure sensor in the first fluid containing system. The first fluid containing system comprises a first pulse generator, and the second fluid containing system comprises a second pulse generator. The pressure sensor is arranged to detect first pulses originating from the first pulse generator and second pulses originating from the second pulse generator. The integrity of the fluid connection is determined based on the presence of second pulses in the measurement signal. The second pulses may be detected by analysing the measurement signal in the time domain and/or by using timing information indicative of the timing of the second pulses in said at least one measurement signal. The analysis may be based on a parameter value that represents a distribution of signal values within a time window of the measurement signal. The parameter value may be calculated as a statistical dispersion measure of the signal values, or may result from a matching of the signal values within the time window to a predicted temporal signal profile of a second pulse. The fluid connection may be established between a human blood system and an extracorporeal blood flow circuit. | 05-05-2011 |

20110040502 | METHOD AND DEVICES FOR MONITORING FLOW CIRCUITS - A device is provided for monitoring the integrity of a flow circuit in fluid communication with a receptacle. The flow circuit comprises a pumping device for transferring fluid through the flow circuit. The device operates according to a monitoring method in which a pressure signal is received from a pressure sensor, the pressure signal being indicative of fluid pressure in the receptacle or the flow circuit. The pressure signal is then processed for detection of a beating signal. The beating signal manifests itself as an amplitude modulation of the pressure signal and is formed by interference between pressure waves generated by a pulse generator associated with the receptacle and pressure waves generated by the pumping device. The integrity of the flow circuit is determined based at least partly on the presence or absence of the beating signal. The device and the flow circuit may be part of an apparatus for extracorporeal blood treatment, and the method may be implemented as a computer program product. | 02-17-2011 |

20110026660 | DIGITAL NUCLEAR CONTROL ROD CONTROL SYSTEM - A digital rod control system that employs separate power modules to energize the respective coils of a magnetic jack control rod drive rod drive system so that two, independently powered grippers can simultaneously support the control rod drive rod when it is not in motion to avoid dropped rods. The basic building block of the system is two or more selecting cabinets which receive multiplex power from at least one moving cabinet and are under the control of a single logic cabinet. Each of the cabinets include monitoring features to confirm the reliability of the system. | 02-03-2011 |

20100263029 | METHOD AND SYSTEM FOR GENERATING ONE-TIME PASSWORDS - A method for one-time password generation, the one-time password being used for user authentication by a restricted resource. The one-time password is generated by means of a mathematical algorithm in a user-specific device, and the one-time password is generated by the mathematical algorithm using at least one user-specific password generation parameter. A first password generation parameter is used for generating a first one-time password for use in user authentication by a first restricted resource, and a second password generation parameter is used for generating a second one-time password for use in user authentication by a second restricted resource, the second restricted resource being different from the first restricted resource, and the first and second password generation parameters being distinct. | 10-14-2010 |

20080203797 | Control mechanism for a chair - A tilt control mechanism for an office chair includes a spring assembly therein which controls the tilt tension on the back assembly. The tilt control mechanism includes a control plate mounted to the control shaft on which the uprights are mounted, wherein the control plate rotates in combination with the uprights. This control plate is located within the control body and cooperates with a front stop assembly and a back stop assembly to vary the limits of forward and rearward tilting of the seat and back assemblies. Also, the tilt control mechanism includes a pneumatic actuator assembly having fixed and rotatable cam blocks. The rotatable cam block rotates relative to the fixed block such that the rotatable cam block is driven downwardly to depress the control valve of the pneumatic cylinder and thereby vary the height of the seat assembly. | 08-28-2008 |
