Filed:

Aug 3, 2004

Appl. No.:

10/910074

Inventors:

Dennis C. Leiner - Cape Elizabeth ME, US
Michael Bush - South Portland ME, US

Assignee:

Lighthouse Imaging Corporation - Portland ME

International Classification:

A61B 1/00

US Classification:

600101, 600117, 600127, 356 731, 356124

Abstract:

The invention uses optics and precision mechanisms to quantitatively assess the performance of medical endoscopes. By viewing standardized optical targets under well-controlled conditions, the optical quality of endoscopes can be easily determined in much the same fashion as getting one's eyes tested at the optometrist. The actual design, however, is much more complicated than your optometrist's eye chart and different types of endoscopes from different manufacturers require customization of the target geometry, the viewing distance, and the viewing angle. Also, there are several optical characteristics beyond image sharpness that need to be assessed, requiring other unique test geometries, including contrast, distortion, and vignetting. Clinically significant measurements are performed with simplicity and cost-effectiveness through the use of relatively inexpensive optical components and an embedded processor and graphical display system.

Abstract:

An endoscopic illumination tester is provided for testing illumination quality of a light source. The endoscopic illumination tester includes an optical bridge that is removably interlockable with the light source. The endoscopic illumination tester includes an integrating sphere that is removably interlockable with the optical bridge. The endoscopic illumination tester may further engage a light guide connectable between the optical bridge and the light source. An endoscope may be inserted between the optical bridge and the integrating sphere.

Assignee:

Lighthouse Imaging Corporation - Portland ME

International Classification:

A61B 1/06

US Classification:

600167, 600173

Abstract:

An endoscopic coupler by which the rotary and/or linear motion of an external ring is transferred via magnetic interaction of specially configured continuous plastic magnets to a lens resident in a hermetically sealed housing to effect focusing and/or zooming action of the lens without mechanically breaching the integrity of the hermetic seal thereby making the coupler particularly suitable for withstanding the rigors of autoclaving.

International Classification:

G01N 31/00

US Classification:

422 64

Abstract:

A chemical analyzer includes a slide transport mechanism having a slide track adapted to hold a plurality of reagent test slides, a sample metering device, an incubator formed as a part of the slide transport mechanism to precisely maintain the temperature of the reagent test slides, a slide ejector mechanism to remove the slides from the slide transport mechanism, a sample preparation station, which includes a centrifuge, and associated electronics and software. The slide transport mechanism holds a plurality of trapezoidally-shaped reagent test slides about its circumference, which slides are loaded onto the transport mechanism by the slide inserter mechanism. The slide transport mechanism positions the reagent test slides under the sample metering device, which device deposits a predetermined volume of sample onto each slide. The slide transport mechanism also carries the slides above a reflectometer. After testing has been completed, the slide ejector mechanism automatically removes the reagent test slides from the slide transport mechanism.

US Classification:

700258

Abstract:

An adaptable container handling robot includes a chassis, a container transport mechanism, a drive subsystem for maneuvering the chassis, a boundary sensing subsystem configured to reduce adverse effects of outdoor deployment, and a controller subsystem responsive to the boundary sensing subsystem. The controller subsystem is configured to detect a boundary, control the drive subsystem to turn in a given direction to align the robot with the boundary, and control the drive subsystem to follow the boundary.

International Classification:

A61G 7057

US Classification:

5653

Abstract:

A cushion system for supporting a body such as a seated person at risk of developing pressure sores. An array of one or more foam members is biased such that each foam member exhibits a substantially constant force per unit area when supporting the body. The bias may be passive, by choice of foam characteristics, and additionally, may be applied actively by providing a gas to the foam and controlling the pressure of the gas in response to the pressure conditions at the interface with the supported body.

International Classification:

G01J 3/02
G01N 21/71
G01N 21/13

Abstract:

Devices and methods are disclosed that allow for analysis with simplified sample preparation. Of particular relevance is the analysis of wire samples (e.g., weld wires) using laser induced breakdown spectroscopy (LIBS) or optical emission spectrometry (OES). Representative devices can isolate a sample, such as in a sealed, inert environment in an analytical instrument. These devices may include first and second sample end attachments connected to a body, which has a connecting portion that may be configured for alignment with the face of the instrument. The body may also include a rotatable cap, and the sample end attachments may be joined to this cap (e.g., at opposite ends thereof) to allow adjustment of the angular position of the sample, relative to the connecting portion, which in use may be affixed to the instrument.
