20080212103 | Ultra-Short Optical Pulse Measurement Using a Thick Nonlinear Crystal - The invention provides a pulse measurement apparatus and corresponding method. The apparatus comprises: a splitter for splitting a pulse to be measured into two sub-pulses propagating along different beam paths; a non-linear medium, capable of up-conversion of radiation propagating therethrough, arranged in said beam paths; at least one element for interfering the up-converted pulses resulting from propagation of the two sub-pulses in the non-linear medium; and detection apparatus for detecting the result of the interference to obtain at least one of spectral and temporal characteristics of the pulse to be measured. In the non-linear medium, each sub-pulse can be resolved into an o-wave component and an e-wave component propagating through the medium at a predetermined angle, and the phase-matching function for up-conversion by interaction of the o-wave component with the e-wave component in the non-linear medium is selected such that up-conversion is substantially independent of frequency for one of the o-wave or e-wave over a predetermined frequency range, and is frequency selective for the other of the o-wave and e-wave. This phase-matching function produces spectrally-sheared up-converted replicas of the pulse to be measured. | 09-04-2008 |

20090204050 | Method and System for Colloid Exchange Therapy - The present invention relates to a method and system for using a hemofilter to treat IMRD, hepatic failure, exogenous intoxication and other conditions associated with toxins in a patient's blood. One treatment includes the use of a very large pore hemofilter to remove target complex molecules and/or target molecules from a patient's blood and to infuse a replacement fluid into the patient's blood to maintain a prescribed albumin concentration in the patient's blood. | 08-13-2009 |

20100144183 | Method of mounting a connector assembly - A connector for electrical or optical conduits that provides a field configurable keying of the insulator plugs relative to each other and relative to the connector casings. A separate relative keying means is included that is separate from the case keying or locating mechanism. The connector also utilizes a retention means for example, a one-way snap apron, to retain the insulator within the receptacle case. | 06-10-2010 |
