US Patent:

6449088, Sep 10, 2002

Filed:

Nov 5, 1993

Appl. No.:

08/147793

Inventors:

James T. Pettingell - Escondido CA
James T. Snyder - Poway CA

Assignee:

EmCal - San Diego CA

International Classification:

G02B 2100

US Classification:

359386, 359371, 359380, 359381, 359385

Abstract:

A variable dark-field illumination method and apparatus to produce microscopic and macroscopic images with a variable dark-field effect thereby making best use of various detector response characteristics. The variable dark-field of the invention is particularly characterized by an adjustable object contrast which optimizes the use of the various detectors dynamic range. The invention is particularly useful when coupled with a video camera and for macroscopic systems having a large depth object field. The dark-fields of the art have geometries which are objectionable because those geometries have very limited depths of field. The invention is particularly distinguished from the art as the dark-field methods and apparatuses of the art are generally geometrically restrictive and they do not provide variable contrast control for input images.

International Classification:

B62B 116

US Classification:

280 4726

Abstract:

A wheeled hamper has a hinged lid that freely pivots between a closed position and a position, preferably past ninety degrees, at which the lid is latched into place by a releasable catch mechanism. In the latched position, the lid can be used as a handle to tilt the hamper and wheel it. In a second embodiment, the lid has at least one stable position intermediate the closed position and the latched position. It can be held there by detents which can be released by appliying a torque to the lid as opposed to the catch mechanism which in its preferable form does not release simply by application of a torque. This provides a way to keep the hamper open when it is in stationary use and to conveniently close it after such use by simply pulling on the lid as opposed to going through a procedure to release the catch mechanism. Two embodiments of catch mechanisms are disclosed. Other features are also disclosed.

International Classification:

G02B 2126

US Classification:

359391

Abstract:

A microscope stage which provides for displacements in simultaneous rotation and linear translation or combinations thereof while also providing for optical coupling of an illumination light source to an object being addressed. The stage can generally be a plurality of optically transparent plates in proximity to one another having a grease interface therebetween. The grease allows movement of the plates with respect to each other in any direction parallel to their surfaces. The grease and plates are arranged to allow light to be transmitted therethrough. An object can be illuminated through the stage from a source located with the stage between the object and the source.
