Jun 1, 2000

Appl. No.:

09/585487

Inventors:

Kenneth R. Quast - Hutchinson MN
Mark A. Schmidt - Darwin MN
Sergey I. Gritsenko - Hutchinson MN
Mark S. Lewandowski - Hutchinson MN
Dean E. Myers - Stewart MN

Assignee:

Hutchinson Technology Incorporated - Hutchinson MN

International Classification:

G02B 636

US Classification:

385 78

Abstract:

An optical connector latch to optically couple at least one optical fiber ferrule on an interface housing with an optics receptacle mount on an instrument and a method of using the same. The optical connector latch comprises one or more shell pegs adapted to advance the interface housing into engagement with the optics receptacle mount. One or more ferrule pins are adapted to extend through latch holes in the interface housing and latch holes in the optics receptacle mount to engage with the optical fiber ferrule. A drive mechanism is provided to drive the shell pegs and the ferrule pins toward the optics receptacle mount.

International Classification:

G02B 626

US Classification:

385 51, 385 24, 385 28, 385 32

Abstract:

An optical structure for combining light from a plurality of individual optical fibers into a single optical transmission device. The structure can be incorporated into the optical probe of a spectrophotometric instrument and includes a plurality of optical send fibers having input and output ends and an optical light mixer having input and output ends. The output ends of the send fibers are secured in optical communication with the input end of the light mixer.

US Classification:

3602446, 3602443, 3602445, 3602452

Abstract:

A head suspension assembly in a rigid disk drive having a load beam with a mounting region, a rigid region and a spring region located between the mounting region and rigid region. The mounting region includes an integral boss tower having attachment features. A method of making a multi-piece head suspension for a rigid disk drive is also disclosed. The method includes providing a first layer including a mounting region with an integral boss tower attached to a stiffener by one or more positioning tabs; attaching a second layer including a spring region to an interface between the mounting region and the stiffener; attaching a flexure to the stiffener; and removing the positioning tabs. The flexure can optionally be a portion of the second layer.

International Classification:

A61B 500

US Classification:

600344

Abstract:

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.

US Classification:

714 43, 714 41, 714 49, 714 54, 714703

Abstract:

A method and device are provided that use a sequencer in the device to control interactions on an interface bus. The sequencer is programmed to interrupt a co-processor before execution of a command. Based on the interrupt signal and a stored error mode page, a false error condition is initiated by further programming the sequencer to operate abnormally. After recovery from the error condition, the sequencer is reprogrammed to operate normally.
