Robert J Pressley: Optical beam homogenizer. Allied Corporation, James Riesenfeld, Gerhard H Fuchs, October 2, 1984: US04475027 (146 worldwide citation)

An optical beam homogenizer divides and redirects an incident beam to provide uniform irradiation to a plane surface. The beam homogenizer is particularly useful in an apparatus and method for uniform laser irradiation of materials. The apparatus comprises a laser, a beam homogenizer, and a support ...

Leroy G Meshel, Robert J Pressley, Robert Butcher, Theodore Fahlen: Semi-opaque corneal contact lens or intraoccular lens and method of formation. Lens Plus Co, Flehr Hohbach Test Albritton & Herbert, May 17, 1988: US04744647 (58 worldwide citation)

A selected pattern of disruptions in the lens material of a soft or hard corneal contact lens or intraoccular lens is provided which substantially disrupts the undistorted transmisability of an image to the lens to render it semi-opaque. Preferably, these disruptions are formed by a laser beam which ...

Steven T Cho, Alfred S Conte, Paul N Ludwig, Anthony P Schmid, Theodore S Fahlen, Robert J Pressley: Gap jumping to seal structure, typically using combination of vacuum and non-vacuum environments. Candescent Technologies Corporation, Ronald J Meetin, Skjerven Morrill MacPherson Franklin & Friel, August 29, 2000: US06109994 (40 worldwide citation)

Portions (40 and 44) of a structure, such as a flat-panel device, are sealed together by a gap-jumping technique in which a sealing area (40S) of one portion is positioned near a matching sealing area (44S) of another portion such that a gap (48) at least partially separates the two sealing areas. T ...

Robert J Pressley: Laser process for gettering defects in semiconductor devices. Allied Corporation, James Risenfeld, Gerhard H Fuchs, November 15, 1983: US04415373 (10 worldwide citation)

A process for gettering defects in a semiconductor is provided. The process comprises using a laser beam to drive a dopant material into a melted non-active surface of a semiconductor device, followed by heating the semiconductor to drive defects to traps formed by the dopant. The process creates in ...

Anthony J Cooper, Floyd R Pothoven, Paul N Ludwig, Theodore S Fahlen, Robert J Pressley: Gap jumping to seal structure including tacking of structure. Candescent Technologies Corporation, Ronald J Meetin, Skjerven Morrill MacPherson Franklin & Friel, October 13, 1998: US05820435 (7 worldwide citation)

A structure, such as a flat-panel device, is sealed together by a gap-jumping technique in which an edge (44S) of a wall (44) is positioned near a matching sealing area (40S) of a plate structure (40) such that a gap (48) at least partially separates the edge of the wall from the sealing area of the ...
