US Patent:

57046000, Jan 6, 1998

Filed:

Dec 5, 1995

Appl. No.:

8/567284

Inventors:

Brian Owen Robinson - Fraser MI

International Classification:

B23Q 306

US Classification:

269 32

Abstract:

A power operated clamp assembly 10 includes a clamp body 12, a reciprocatable member 20 extending into the clamp body 12, and a clamp arm 22 pivotally mounted to the clamp body 12 by a first pivot element 36. The clamp arm 22 is pivotable about a pivot axis 38 of the first pivot element 36 between first and second positions of movement termination C and D, respectively. A linkage assembly 46 has a drive end 48 adjustably secured to an end 56 of the reciprocatable member 20, and a clamp end 50 operatively secured to the clamp arm 22 so as to pivot the clamp arm 22 as the member 20 reciprocates. The linkage assembly 46 includes a connection pivotable about the pivot axis of a second pivot element 80. The drive end 48 is adjustable with respect to the end 56 of the reciprocatable member 20 so as to allow adjustment of the first and second positions C and D, respectively. One pivot element of the first and second pivot elements 66 and 80, respectively, includes an eccentric shaft having a central axis 124.

International Classification:

A61B 5/00

Abstract:

An optical measurement system comprising an optical source configured for delivering sample light in an anatomical structure, such that the sample light is scattered by the anatomical structure, resulting in physiological-encoded signal light that exits the anatomical structure, an optical detector configured for detecting the physiological-encoded signal light, and a processor configured for acquiring a TOF profile derived from the physiological-encoded signal light, the initial TOF profile having an initial contrast-to-noise ratio (CNR) between a plurality of states of a physiological activity in the anatomical structure. The processor is further configured for applying one or more weighting functions to the initial TOF profile to generate a weighted TOF profile having a subsequent CNR greater than the initial CNR between the plurality of states of the physiological activity. The processor is further configured for processing the weighted TOF profile, and identifying one of the plurality of states of the physiological activity.
