Patent number: 7034862Abstract: A sequence of electronically captured images are converted into modified images providing the appearance of images captured by a film reproduction system, where the film reproduction system is of the type that includes a motion picture negative film printed onto a motion picture print film that is displayed, or a reversal motion picture system in which a reversal film is displayed. After electronically capturing the images, the electronically captured image data is transformed into linearized exposure data, which is subsequently transformed with a linear function that emulates a film exposure of the film reproduction system. The exposure-corrected images are then transformed with a non-linear function that renders the exposure-corrected images with a tone scale of the film reproduction system, and the tonescale-corrected images are transformed with a linear function that emulates a film color look provided by the film reproduction system.Type: GrantFiled: November 14, 2000Date of Patent: April 25, 2006Assignee: Eastman Kodak CompanyInventors: Karleen M. Cirulli, John C. Brewer, Nestor M. Rodriguez

Patent number: 6985253Abstract: Scanner density values of a digitized image of an original film are processed so that a projection of the digitized image closely matches that image which a film projector would produce when projecting the original film. A method comprises the steps of transforming the scanner density values to printing density values; digital color balancing by writing the printing density values and a LAD patch onto film; printing the film is printed to LAD; transforming the images from device dependent color space values into device independent color space values; carrying out a relationship between the device independent color space and a display device output to obtain RGB code values; adjusting any non-linearity between the RGB code values and the display device output; and scaling the adjusted RGB code values to an appropriate bit depth.Type: GrantFiled: December 28, 2000Date of Patent: January 10, 2006Assignee: Eastman Kodak CompanyInventors: Ricardo R. Figueroa, Thomas O. Maier, John C. Brewer

Patent number: 6864915Abstract: An electronically originated image is converted into a modified electronic image simulating an image originated from a film system and converted into an electronically displayed image. The technique employed is based on a set of electronic camera system spectral product curves that are substantially approximated by a linear combination of a set of spectral product curves characteristic of the film system. An image is captured having red, green and blue exposure signals resulting from these electronic camera system spectral product curves, and the red, green and blue exposure signals are then converted into a modified electronic image simulating an image originated from a film system and converted into an electronically displayed image. Because of the linear approximation between the spectral product curves, the conversion step can be performed by a matrixing operation.Type: GrantFiled: October 27, 2000Date of Patent: March 8, 2005Assignee: Eastman Kodak CompanyInventors: Marcelo de C. Guimaraes, John C. Brewer, Nestor M. Rodriquez

Patent number: 6680099Abstract: A means and method of enhancing the damage tolerance of adhesive bonds by introducing gaps in the adhesive to divide the adhesive layer into discrete regions. The gaps are created by placing strips of barrier material between the two adherends before the adhesive is put in place and cured. If the two adherends begin to debond along the interface between one of the adherends and the adhesive, the gap arrests the debonding process.Type: GrantFiled: January 21, 1997Date of Patent: January 20, 2004Assignee: The United States of America as represented by the Secretary of TransportationInventor: John C.

Patent number: 6015105Abstract: A machine, a method, and an air-cooled cutting brush for removing tread material for recycling from used motor vehicle tires prior to scrapping or retreading without damaging the tire cords and beads. The tread material is removed as fine particles, or buffings, ready for recycling without subsequent sorting out of cloth or metal. A tire is mounted in an upright position on a tire receiving assembly which expands to grip the tire beads. The tire receiving assembly is mounted on a supporting structure which pivots. An elongate, powered, rotating, cutting brush is mounted on a rolling mounting structure which moves the cutting brush into and out of engagement with the tread on the outer, ground-contacting portion and on the sidewalls of a tire. In operation, the tire is rotated as the cutting brush engages the tread material of the ground-contacting portion, the supporting structure is then pivoted to remove the tread material of one sidewall, and repeated on the opposite sidewall.Type: GrantFiled: April 24, 1998Date of Patent: January 18, 2000Assignee: Garb-Oil & Power CorporationInventor: John C. Brewer
