Title: Identifying microorganisms by measuring enzymatic activity in the presence of enzyme activity affecting agents
Inventor: SUSSMAN MARK L
IPC: C12Q1/37
Filed: 1991-03-15
Granted: 1995-11-21
Abstract: A method for rapidly identifying microorganisms by determining  the  rates  of  enzymatic  hydrolysis  of  a plurality of substrates in the presence of at least one enzyme activity affecting agent, called an "affector" is provided.   The substrates are selected from fluorogenic and  chromogenic  substrates  to  create  a  characteristic pattern of enzymatic cleavage rates by enzymes expressed by the unidentified microorganism.   This characteristic pattern of enzymatic cleavage rates is a "fingerprint" of the unidentified microorganism when in the presence of the affector.  The pattern of enzymatic cleavage rates for the unidentified microorganism is compared to a pattern of enzymatic cleavage rates of the same substrates in the presence of the same affector for one or more identified classes or subclasses of microorganisms.  The unidentified microorganism is then identified as belonging to a class or  subclasses  of  the  known microorganisms  which most closely matches the pattern of enzymatic cleavage rates in the presence of the affector.

Title: Special effects carrier
Inventor: ADOLPHI JOHN
IPC: G03B15/10
Filed: 1992-12-08
Granted: 1999-06-01
Abstract: A special effects carrier for use in a photographic camera for taking portraits of individuals or groups. The wheel-shaped special effects carrier contains masks which produce various special effects. One of the masks included on the carrier produces no special effects so that the carrier can be used whether or not a special effect is desired. The carrier is located a fixed distance behind the objective element of the zoom lens so that the photographer is able to focus the camera without having to compensate for the changing focal length of the zoom lens. The carrier is connected to a CPU which drives a motor to rotate the carrier. An optical sensor reads bar codes on the carrier and relays information to the CPU thereby allowing the CPU to position the masks for use and freeing the photographer of that task.

Title: Method and apparatus for obtaining the topography of an object
Inventor: CAMBIER JAMES L
IPC: G06T7/00
Filed: 1991-07-15
Granted: 2001-11-20
Abstract: A system, method, and apparatus for obtaining the topography of an object using computer analyzed rasterstereographic images. The object may be nontransparent and diffusing, or it may be transparent and nondiffusing, such as cornea. Rasterstereographic images of a cornea are produced by staining the cornea with a fluorescein solution which projects a light and dark line pattern onto the cornea through a grid. When obtaining the topography of a cornea, several different filters are used for producing and obtaining a grid image. An image processor uses unique software to store and analyze data extraced from the grid pattern. A video camera, an illuminator, the filters, and the grid may be mounted on a microscope. One embodiment uses a grid with vertical lines. Another embodiment uses a grid having intersecting horizontal and vertical lines for exhibiting surface details in a two-dimensional x-y plane. A computerized method and associated apparatus uses the data from the x-y plane to determine the projected grid intersection points on the surface of the cornea by intersecting a light ray formed by the grid intersection points on the actual grad in the projected system with a light ray formed by the grid intersection points of the image in the camera system.

Title: Slim-scan module with interchangeable x-y scan element
Inventor: DVORKIS PAUL
IPC: G02B26/10
Filed: 1993-09-28
Granted: 1999-05-04
Abstract: An optical scanning module has a metal base,  a first circuit board mounted across one end of the metal base and a second circuit board mounted orthogonal to the first circuit board.   The metal base supports a light emitter for producing a scanning beam and serves as a heat sink for the emitter.   A flexible support attached  to  the metal  base  supports  a  mirror  for oscillating motion.    The  module  includes  a  drive mechanism, typically in the form of a permanent magnet and electromagnet, for producing reciprocal motion of the mirror.  A detector included in the module senses light reflected from an indicia scanned by the beam.  A flexible electrical cable connects the circuitry on the first  and  second  circuit  boards  so  that circuitry operates together to produce all signals necessary for operation of  the scanner module and to process the electrical  signals  from  the  detector.    Preferred embodiments include a flexible support consisting of a planar spring located between the mirror and one of the magnets.  The components of the module are dimensioned so that the weight of the magnet balances that of the mirror.   The invention also encompasses systems for scanning the beam  simultaneously  in  two  orthogonal directions  at two  different  frequencies.   This bi-directional scanning can produce a raster scan pattern for reading two-dimensional bar codes, or this scanning can  produce  a  moving  zig-zag  pattern  for reading truncated bar codes.
