Title: Passive, non-invasive method to quantify objectively the level and density of a neural blockade
Inventor: STERNBERGER WAYNE I
IPC: A61B5/0245
Filed: 1998-08-25
Abstract: Electromyogram, temperature and heart rate measurement which correlate to the dermatome level, and density of neural blokade are obtained in a passive manner, i.e., the patient is not stimulated, or exposed to any sensor that requires an active conduction in order to make a measurement. No active patient participation or response is required. The measurements obtained provide objective and quantitative indications of, for example, epidural blockade with local anesthetics thus allowing objective real time assessment of density, and level of neural blockade.

Inventor: PAFFENHOLZ JOSEF
IPC: G01V1/36
Filed: 2000-05-03
Abstract: In a marine seismic survey, water bottom travel times are obtained by conventional methods. Near offset seismic data are then dereverberated using a suite of possible water bottom reflection coefficients to give a suite of filtered traces.   The water bottom reflectivity that gives the minimum value over the suite of processed traces is determined to give a set of selected reflectivities each of the analysis points within a time window. A weight is determined for each analysis time within the time window, the weight being related to the change in the amplitude of the filtered trace at that sample point over the suite of water bottom reflectivities. The selected reflectivities are weighted by the weights and averaged to make a determination of the water bottom reflectivity. This determined water bottom reflectivity is used to process the recorded seismic trace. This determined water bottom velocity may also be used to obtain the upcoming dereverberated wavefield in a dual sensor array wherein a hydrophone-geophone combination is used to record data at the ocean bottom.

Abstract: An improved drive system for a shrimp peeling apparatus (10) includes a support frame (11) with a first (25) and a second (26) plurality of rollers mounted thereon. One of the plurality of rollers have rollers (25) that are of a larger diameter than the other rollers (26). The drive mechanism includes a computer controlled motor (61) that engages a cylindrically-shaped shaft (31) of each roller and a drive mechanism that engages the cylindrically-shaped end portion. The motor drive (61) can be a computer controlled vector motor that can vary the rotation angular movement of each roller during each stroke. This enables variations in angular rotation and rotation speed depending upon the type and grade of shrimp. This configuration also enables each roller to constantly "advance" by changing the degree of angular rotation of each roller at each stroke, gradually presenting a different wear surface (37) to the shrimp and prolonging roller life.
