Patent number: 5634929Abstract: The invention comprises a rigid frame that is positioned around the skull to define a multi-dimensional coordinate system. Multiple arms are coupled to the frame, each arm having an attachment assembly movable along a longitudinal axis directed toward the center of the rigid frame assembly. Multiple receptors are either attached to the skull or drilled into the skull for receiving an associated attachment assembly. The receptors provide a mounting base upon which the frame is repeatedly attached and detached from the skull at the same reproducible reference location. Each arm has a multi-station receptacle that receives various attachments used for mounting and attaching the receptors. Special bushing are used to lock the attachment assembly in a preset longitudinal position in relation to the arm. The locked attachment assembly can then be removed from the arm allowing the frame to be removed from the skull while maintaining frame position information.Type: GrantFiled: October 26, 1994Date of Patent: June 3, 1997Assignee: Oregon Neuro-Medical Technology, Inc.Inventors: John Misko, Robert J.

Patent number: 5586875Abstract: A first pump includes inner and outer intermeshing rotors, the outer rotor formed with external gear teeth. A second pump includes inner and outer meshing rotors, the outer rotor of the second pump having teeth continually engaged with the external teeth of the first pump outer rotor. The inner and outer rotors are formed with mutually intermeshing lobes that define between them pumping chambers through which hydraulic fluid is moved from a suction inlet to a pressurized outlet. A third pumping element includes pumping chambers located in the spaces between the intermeshing involute gear teeth on the outer rotors of the first and second pumps. A passage plate defines suction and pressure passages, which carry hydraulic fluid from a reservoir or sump to outlet ports, through which fluid is supplied to the hydraulic system.Type: GrantFiled: July 10, 1995Date of Patent: December 24, 1996Assignee: Ford Motor CompanyInventors: Richard T.

Patent number: 5554329Abstract: High capacity, low cost fractionation trays are formed from a number of adjacent triangular (v-shaped) downcomer modules. The trays are free of the horizontal perforated decking surface of conventional trays. The downcomer modules have perforations only in a bottom region for liquid passage and in an upper region for vapor passage, with the central portion of the two inclined downcomer sidewalls being imperforate. The difference in elevation between the bottom region and upper region is considerably larger than a ripple tray. A layer of packing material may be provided close to or adjacent the bottom surface of the tray.Type: GrantFiled: March 13, 1995Date of Patent: September 10, 1996Assignee: UOPInventors: Daniel R.

Patent number: 5543590Abstract: A proximity sensor system includes a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads. The capacitance changes as a function of the proximity of an object or objects to the sensor matrix. The change in capacitance of each node in both the X and Y directions of the matrix due to the approach of an object is converted to a set of voltages in the X and Y directions. These voltages are processed by circuitry to develop electrical signals representative of the centroid of the profile of the object, i.e, its position in the X and Y dimensions. Noise reduction and background level setting techniques inherently available in the architecture are employed.Type: GrantFiled: September 2, 1994Date of Patent: August 6, 1996Assignee: Synaptics, IncorporatedInventors: David Gillespie, Timothy P. Allen, Robert J. Miller, Federico Faggin

Patent number: 5520717Abstract: Sonochemistry permits extremely rapid cooling from the melt which is necessary for forming amorphous metals. Sonochemistry also functions at an extremely small scale to produce nanophase particles. If magnetic, these particles are valuable for magnetic recording media, manufacture of permanent magnets, and other uses. The nanophase particles agglomerate, however, which limits their utility for these magnetic applications. To keep the particles isolated, we extract the particles from the n-alkane reaction solvent in a polar solvent and cast the extracted particles with a polymer, such as polyvinylpyrrolidone.Type: GrantFiled: June 7, 1995Date of Patent: May 28, 1996Assignee: The Boeing CompanyInventors: Robert J.

Patent number: 5143088Abstract: An apparatus is disclosed for monitoring the functional motion characteristics of the spine in each of three planes. The apparatus is designed to be mounted on the back of a patient, and it includes an exoskeleton of T-shaped elements which resemble the spinous process and the transverse process of the spine. The elements each include a central bore for receiving a cable, and three separate openings for receiving a wire therethrough. The cable is attached to a potentiometer which measures twisting movement of the spine, and each of the three wires is attached to a separate potentiometer so as to measure flexing in the and sagittal and lateral planes. The signals from the potentiometers are processed so as to provide, for each of the three planes, a measurement of the angular position of the spine as a function of time, the angular velocity as a function of time, and the angular acceleration as a function of time.Type: GrantFiled: May 6, 1991Date of Patent: September 1, 1992Assignee: William S.
