Granted: 2004-06-22
Abstract: A drowsiness detection system constructed according to the invention provides improved performance by preserving and analyzing newly discovered information contained in rhythmic signal components above 30 Hz which the prior art has universally ignored or discarded as "noise." In the first and second embodiments of the invention, one or more analog EEG signals are collected from a subject, appropriately filtered, converted into digital form, and subjected to frequency analysis. Selected signal components from the frequencies above 30 Hz (such as the frequency range 80-420 Hz), which have a high correlation with subject drowsiness, are isolated, and their amplitude, energy, or power contribution to the EEG signal is used to produce a continuous output measure reflecting the subject's alertness or drowsiness. The output measure may be compared with a threshold to provide an indication of whether the subject is excessively drowsy. In a third embodiment, the analog EEG signal is supplied to a plurality of analog signal processing channels corresponding to respective predefined frequency ranges. Selected signal components in frequencies above 30 Hz are isolated (in a manner analogous to that of the first and second embodiments), and their amplitude, energy, or power contribution to the EEG signal is used to produce a continuous output measure reflecting the subject's alertness or drowsiness.

Title: Device for pressure treatment of wood
Inventor: JOHANNISSON TOM
IPC: B27K5/00
Filed: 1996-04-12
Granted: 2006-06-06
Abstract: A device for pressure treatment of wood elements comprises a pressure chamber (1) for accommodating the wood elements (5a, 5b, 5c) which are to be treated. The pressure chamber also accommodates a pressure medium which surrounds the wood elements on more than one side and, at least before the pressurization, a secondary medium in the form of a fluid. When the pressure medium is pressurized, the wood elements are subjected to a multilateral pressure, whereby they are permanently compressed. Further, the pressure chamber is provided with means (11a, 11b) for controlling the quantity of secondary medium which penetrates into the wood during the treatment. These means may consist of evacuating valves (11a) or of casings (11b) which surround the wood elements and which are impenetrable to the secondary medium.

Abstract: Method and apparatus for static and dynamic support of a grid system voltage by means of a static power factor correction device having a self-commutated converter.        The invention relates to a method for static and dynamic support of a grid system voltage (v) at a network node (PCC) by means of a static power factor correction device (2) which has a transformer and a self-commutated converter (12) with at least one capacitive energy store (14), and an apparatus (8) for carrying out the method.      According to the invention, instantaneous reference values (q ref, i svref) for a secondary instantaneous control method are determined continuously as a function of determined voltage magnitude errors of the grid system voltage (v) at the network node (PCC), by means of which secondary instantaneous control method a phase angle (.delta.) is determined as a function of determined instantaneous actual values (q, i sv), by means of which phase angle (.delta.) the angle (.sigma.) of the converter voltage space vector ((v s) of the self-commutated converter (12) is produced as a function of the angle .PHI. of the grid system voltage space vector (v). This results in dynamic regulation of the reactive volt-amperes required for grid system voltage regulation.

Title: Method for determining seismic data traveltime fields on a massively parallel computer
Inventor: WILLEN DENNIS E
IPC: G06F17/16
Filed: 1996-07-25
Granted: 2000-05-09
Abstract: A method (Figure 3) of determining traveltime fields for use in processing geophysical data. The method is implemented on a computer (100) having massively parallel processors (114, 116). The input to the method is a three-dimensional velocity model of a volume of the subsurface (121) of the earth.  The method assigns the traveltime calculations to groups of processors (112), which calculate traveltimes for individual shots. A preliminary simulation of the traveltime calculation process is performed to determine the number of processors required in each group (112). The groups of processors (112) perform the traveltime calculations independent of the other groups.  Calculations are performed in spherical coordinates (?.theta.?), with traveltimes interpolated to a rectangular grid for storage (106) and subsequent use. The final traveltimes are compressed in a differential format to reduce data storage and transfer requirements. A control processor (110) is used to dynamically assign calculation tasks to processor groups (112), thereby ensuring load balance across all groups and maximizing throughput of the massively parallel processors (114, 116).

Abstract: An unwrought continuous cast Cu-Ni-Sn spinodal alloy and a method for producing the same is disclosed. The Cu-Ni-Sn spinodal alloy is characterized by an absence of discontinuous .gamma. phase precipitate at the grain boundaries, ductile fracture behavior during tensil e testing, high strength, excellent wear and corrosion resistance, superior bearing properties, and contains from about 8-16 wt.% nickel, from about 5-8 wt.% tin and a remainder copper. As a method for producing the spinodal alloy, a continuous cast Cu-Ni-Sn billet, hollow billet, or rod composed of small, equiaxed crystals is subjected to solution heat treatment and aging steps to effect spinodal decomposition type phase transformation. According to our invention, it is not necessary to subject the cast rod, billet or casting to wrought processing prior to the spinodal decomposition heat treatment in order to obtain a strong and ductile material, thereby allowing for the use of the unwrought continous cast Cu-Ni-Sn spinodal alloy in the manufacture of various components which heretofore have been manufactured from materials other than an unwrought Cu-Ni-Sn spinodal alloy.

Title: Thermal gradient beveling of catheters
Inventor: AHLSTROM ROGER
IPC: B29C57/00
Filed: 1997-12-11
Granted: 2007-04-10
Abstract: A process for forming a catheter tip is described wherein a mold having an internal surface complimentary to the desired external surface of the catheter tip is formed such that it has two temperature zones. A first higher temperature zone is positioned proximally of the catheter distal tip and a lower temperature zone is positioned distal to the higher temperature zone. A catheter to be tipped is placed upon a mandrel or needle and the mold is heated. Upon insertion of the catheter and mandrel into the mold. The catheter material softens and begins to flow within the mold.      The higher temperature portion supplies the heat necessary to soften the catheter material and it flow to the lower temperature zone wherein the lower temperature causes the catheter material to become more viscous or resolidify. Upon becoming more viscous, the catheter material, at the very tip, acts as a dam to prevent further flow of material thus eliminating flash from the mold end.

Title: Ultrasonic device for inspection of metal parts
Inventor: WHITE DENNIS A
IPC: G01N29/04
Filed: 1997-05-29
Granted: 2004-04-06
Abstract: An ultrasonic transducer is used for inspecting a Yankee dryer and detecting flaws in a portion of the surface of the dryer by directing the ultrasonic beam at the surface to be inspected at a particular angle, for which about ten percent of the signal will appear as Harris waves which propagate into the test plate at ninety degrees to the surface. This signal which propagates vertically is polarized, with the result that the signal has a greatly improved signal to noise ratio. For an incident medium of water and employing shear wave refracting in the medium of cast iron the specific angle is approximately 33 degrees from the vertical for best signal to noise ratio. For steel and specific angle is approximately 31 degrees and is about 50 degrees for brass. Shear or longitudinal waves can be employed to affect the detection of subsurface defects with the particular angle changing depending on the relation of the velocity of the sound waves in the refracting medium to the velocity of sound waves in the incident medium.
