Filed:

Jul 15, 2002

Appl. No.:

10/194276

Inventors:

Daniel M. Brown - Madison AL
Peter Scott Erbach - Harvest AL
Joseph Larry Pezzaniti - Harvest AL
Takahisa Minamitani - Lacey Spring AL

Assignee:

MEMS Optical, Inc. - Huntsville AL

International Classification:

B02B 2710

US Classification:

359619, 359621, 345 32, 345 55

Abstract:

A display and method of displaying multidimensional images on an autostereoscopic display includes establishing a lenslet array to include a plurality of lens elements. There is an interlacing of a plurality of multiple images on the display with a fanning of the multiple images out into an angular array. The method establishes a plurality of views in a vertical and horizontal direction. A mapping of a plurality of views onto a plurality of pixels makes up the display and a three dimensional image is generated from the fanned out multiple images.

International Classification:

G02F001/1395

US Classification:

349 15, 349 95, 359463, 359466

Abstract:

An autostereoscopic display and method of displaying multidimensional images involves a first lenticular array preferably of cylindrical lenses positioned between a viewer and a pixel array, and a second lenticular array also preferably of cylindrical lenses positioned between the first lenticular array and the viewer. The pixel array includes several pixel groups that project images through corresponding groups of first lenses within the first lenticular array. A pitch of the lenses within the second lenticular array differs from a pitch of the lenses in the first lens groups within the first lenticular array. The display can be manufactured or retrofit with the first and second lenticular arrays. By use of the first lenticular array, light from plural color pixels may be focussed to a single point so that color subpixels arranged in a direction transverse to the direction of the cylindrical lenses of the first lenticular array may be focussed to a single point on the secondary lenticular array and then as a single image to the user.

US Classification:

430/321000, 430/322000, 359/485000

Abstract:

Methods and apparatuses for minimizing the errors associated with substrate etching are presented. The methods and apparatuses use intentional defocusing of the pattern image on the photoresist to minimize errors in the etching process particularly grayscale etching and multiple exposure contributions from neighboring patterns.

International Classification:

G03H 104

US Classification:

359 35

Abstract:

A method is disclosed by which filters are created optically in real time--and tested. This technique is made possible by recent advances in Charge Couple Detector (CCD) detector array technology. Pixel (picture element) size has decreased to the point that real fringes can be detected and displayed. The fringes result from the interference of the optical Fourier transform of a displayed scene with a specified plane wave. Phase information is thus preserved. This is the critical information required in producing a hologram or a holographic matched filter.

Abstract:

A smoke producing method and device of the present disclosure produces a non-incendiary, organic-polymerization based, smoke-producing reaction. Some versions of the smoke are effective carriers for capsaicinoid compounds. The method of generating smoke comprises initiating a frontal polymerization reaction by heating a composition comprising a monomer compound that exothermically polymerizes upon initiation with an initiator compound and an initiator compound that initiates polymerization of the monomer compound present at a mass concentration that is at least five percent of the mass concentration of the monomer compound. The polymerization of the monomer compound is exothermic, and in one embodiment the concentration of initiator compound is at least five percent of the concentration of monomer compound. The smoke mainly comprises thermal decomposition products of the initiator compound.
