Patent number: 6839583Abstract: A disposable tip adapted for use in connection with an optical probe of an instrument. The tip includes a one-piece molded elastomeric base member having a boot and an opaque tissue-engaging surface. The boot releasably mates with and provides an interference/friction fit to the probe. The tissue-engaging surface surrounds and extends from the boot. A window in the base member extends into the boot to transmit light between the probe and tissue. A layer of optically transparent material covers the window on the tissue-engaging surface. Adhesive on the tissue-engaging surface of the base member releasably secures the probe to the tissue being analyzed.Type: GrantFiled: June 1, 2000Date of Patent: January 4, 2005Assignee: Hutchinson Technology CorporationInventors: Mark S.

Patent number: 6667803Abstract: A spectrophotometric instrument including light signal sources, a detector, a processor/controller, a probe and a calibration device. The light signal sources include a source of measurement light signals having measurement light wavelengths and a source of a calibration light signal at a calibration detection wavelength which is different than the measurement light wavelengths. The probe has one or more send fibers coupled to the measurement and calibration light signal sources for transmitting the measurement light signals and the calibration light signal into tissue, and one or more receive fibers for receiving light including the measurement light signals and the calibration light signal. The calibration device is adapted to receive the probe and has an optical filter for transmitting the measurement light signals but not the calibration light signal. The detector is coupled to the receive fibers to generate electrical signals representative of the light received at the receive fibers.Type: GrantFiled: June 1, 2000Date of Patent: December 23, 2003Assignee: Hutchinson Technology, Inc.Inventors: Larry D. Flessland, Sergey I. Gritsenko, Mark S. Lewandowski, Dean E. Myers

Patent number: 6072151Abstract: A method for adjusting the load of a head suspension for supporting a read/write head over a disk in a magnetic disk drive. The suspension includes a load beam having a rigid region and proximal and distal ends, with a base on the proximal end and a flexure on the distal end. A spring region is located between the base and rigid region of the load beam. The spring region includes a pair of arms which extend between the base and rigid region to form a cutout, and a plurality of load adjustment frets which extend across the cutout between the base and rigid region. One or more of the frets can be severed by a laser beam to lower the gram load of the suspension. The gram load of the suspension can be increased by shrinking the frets through exposure to the laser beam. Gram load adjustments can be made with the suspensions in a disk stack assembly by directing the laser beam to the frets through an optical fiber.Type: GrantFiled: December 23, 1998Date of Patent: June 6, 2000Assignee: Hutchinson Technology IncorporatedInventors: Ryan A. Jurgenson, Reid C. Danielson, Brent D. Lien, Mark S. Lewandowski

Patent number: 5879294Abstract: A measurement system and method for measuring a relative concentration of a first form of a chromophore having a first form and a second form. The method comprises irradiating a tissue sample with light at a plurality of wavelengths within a wavelength range within which the first and second forms of the chromophore provide an overlapping spectral response. A detector is provided that detects spectral data emitted from the tissue. Furthermore, the method comprises determining a first and a second 2d derivative spectrum value, at first and second wavelengths, respectively, within said wavelength range at which the first 2d derivative spectrum value varies with the relative concentration of the first form of the chromophore. A scaled, 2d derivative spectrum value is derived from the first and second 2d derivative spectrum values. A memory stores a correlation which provides the relative chromophore concentration as a function of the scaled, 2d derivative spectrum value.Type: GrantFiled: June 28, 1996Date of Patent: March 9, 1999Assignee: Hutchinson Technology Inc.Inventors: David L. Anderson, Galen D. Houk, Mark S. Lewandowski, Dean E. Myers, Joseph P. Ortner
