The invention is a method for printing an image (10) from a halftone binary bitmap (12) having pixels (14a-14g) comprising the steps of: creating a feature location identification filter (16) for a halftone binary bitmap image; using the feature location identification filter to map pixel identifications (18a-18g); assigning a location specific exposure (20a-20g) to the mapped pixel identifications; and exposing media using the location specific exposures to create an image (10) on a printer (24).

The present invention provides a method for creating uniform pressure at a nip comprising the acts of providing a stationary inner core, pivotally mounting a plurality of shoes to the stationary inner core, creating a plurality of annular chambers wherein each of the shoes occupies one of the chambers. In addition, the method further provides filling each of the chambers with a magneto-rheological fluid, surrounding the plurality of chambers, shoes, and stationary inner core with a thin, metal, rotatable shell; detecting a deformation in the shell and changing a magnetic field in at least one of the chambers to change a viscosity of the magneto-rheological fluid to correct the deformation.

A system and method of controlling laser power output levels includes a laser (9) and a control circuit (27) for energizing the laser. A sensor (11) that measures power output from a back facet of a laser element (17) of the laser provides feedback to the control circuit so as to maintain power output from the laser constant. The back facet of the laser element is covered with a coating that has transmission and reflection characteristics that are relatively insensitive to minor changes in the wavelength of the laser. The coating is preferably a thin metallic layer which provides a constant and adequate reflectivity and low transmittance. With the specific metallic layer on the back facet, the transmittance remains relatively consistent even when there is a change in wavelength. This provides for consistent readings at the sensor.

A method of making a panoramic image includes capturing a first image (30) defining a first overlap region (115) capturing a second image (40), and defining a second overlap region (215). Two points (150, 151) in the first overlap region are identified and a first vector (175) overlap region connecting the two points is defined. Two points (250, 251) in the second overlap region which correspond to the two points in the first overlap region are identified and a second vector (275) the two points is defined. If points in the first vector match points in the second vector, determine if the first and second vectors are parallel. If the vectors are not parallel, rotate the second vector image until the second vector is parallel to the first vector.

A system for authenticating an object includes a label (12) with invisible indicia (14) on the object which rotates a polarization of incident light; a digital camera (18) having a light source (20), an image sensor (22), a first polarizing filter (24) having a first orientation, and a second polarizing filter (26) having a second orientation orthogonal to the first orientation; illuminating the label with light from the light source through the first linear polarizer; forming an image with the image sensor using reflected light from the label wherein the reflected light passes through the second polarizer prior to reaching the sensor; wherein the second linear polarizer makes the invisible indicia visible; and authenticating the object.

摘要:
A dressing for wounds includes a useful material, such as dye or biocide, trapped within or behind a gelatin barrier. On application to a wound, metalloproteinases naturally present in the wound diffuse into the dressing and degrade the gelatin, releasing the trapped material. The released material serves various useful purposes, such as indicating the status of the wound or improving wound healing.

An apparatus for printing images including illumination optics (75) that provides uniform area light is disclosed. A mirror (440) receives the uniform area light and redirects the light. A first reflective LCD modulator (90) modulates the redirected light on a site by site basis and reflects the first modulated light to a media plane. A motor (441) moves the mirror on a line parallel to the illumination optics. The mirror redirects the light to a second reflective LCD modulator (95). The second reflective LCD modulator modulates the redirected light on a site by site basis and reflects the second modulated light to the media plane.

A system for creating copy restrictive media is disclosed. The system comprises printing a first pattern of microdots (80) on a first set of documents and printing a second pattern of microdots (82) on a second set of documents. A first key code is associated with the first microdot pattern (80), which allows a copy machine to copy the first set of documents, and a second key code is associated with the second microdot pattern (82), which allows a copy machine to copy the second set of documents. This system allows individual copyright owner to insure that no one else is able to reproduce their copyrighted documents.
