Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41J 2435

US Classification:

347236, 347246

Abstract:

A calibration station ( ) for a printhead ( ) adapted to provide a beam of electromagnetic radiation from a variable electromagnetic energy source onto a sensitive radiation medium, the calibration station ( ), incorporates a sensor ( ) disposed for sensing the beam ( ) provided by the printhead ( ), wherein the sensor ( ) provides an output sensor signal indicative of the sensed power of the beam ( ). A control circuit is adapted to accept the output sensor signal from the sensor and adjusts the variable electromagnetic energy source. A filter is disposed in the path of the beam ( ) between the printhead ( ) and sensor ( ), adapted to transmit to the sensor ( ) a portion of incident electromagnetic radiation over a predefined range of wavelengths, dependent upon a measured response characteristic of the radiation-sensitive medium.

Inventors:

Daniel D. Haas - Webster NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41J 247

US Classification:

347252, 347144

Abstract:

Exposure of a medium is controlled by changing an emission level of a radiation source from a first power to a second power. The second power emits for less time than required by an irradiance profile to traverse a full-width at half maximum of the irradiance profile projected onto the medium along a direction of relative motion between the irradiance profile and the medium. The emission level changes to the first power emits for less time than required by the irradiance profile to traverse the full-width at half maximum of the irradiance profile projected onto the medium along the direction of relative motion between the irradiance profile and the medium. Then the emission level changes to the second power. Brief pulsing of a single binary source can transfer intermediate amounts of thermally transferable colorant from a donor exhibiting a continuous-tone transfer response.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G01T 1/24

US Classification:

25037011

Abstract:

A digital film grain () comprises a phototransistor () which produces an electrical signal having a strength which is related to an input radiation flux. A transponder receives commands and power from a base station () and transmits information quantifying the radiation observed by that digital film grain. An image accumulator () connected to the base station () assembles an image from the profile of radiation reported by a distribution of digital film grains correlated to the locations of those grains.

Abstract:

A method of transferring organic material from a donor element to a substrate includes providing a radiation source; and selecting the power of the radiation applied to the donor element by the radiation source to cause the transfer of organic material to the substrate wherein the time that one or more positions of the donor element receives radiation is greater than 1 millisecond.

International Classification:

B05D 5/00

US Classification:

427256, 427558, 427 66, 427 77, 427457

Abstract:

Methods and apparatuses are provided for assembling a structure on a support having a pattern of binding sites. In accordance with the method, a first fluid is provided on the surface of the support with the first fluid being of a type that that increases viscosity when heated, the first fluid having first micro-components suspended therein each adapted to engage the binding sites. The first fluid proximate to selected binding sites is heated to increase the viscosity of the responsive fluid proximate to the selected binding sites so that the first micro-components suspended in the first fluid are inhibited from engaging the selected binding sites.

International Classification:

B01J 19/08

US Classification:

427457000

Abstract:

A support and a method for fluidic assembly are provided. The support has a surface having binding sites adapted to receive micro-components of a type that are applied to the surface using a fluid; and energy absorbing heat producers at selected binding site. Each energy absorbing heat producer is adapted to receive energy and to transduce a portion of the received energy to heat the fluid proximate to the selected binding sites; so that when the micro-components are applied using a fluid that increases viscosity when heated, the heat generated by the energy absorbing heat producers increases the viscosity of the fluid proximate to the selected binding sites to prevent the micro-components from attaching to the selected binding sites.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41J 2435
B41J 235

US Classification:

347237

Abstract:

A multiple-source array for use in thermal printing uses source interleaving to avoid overlapping of the dye-transfer tracks upon the donor material in a single pass. The array includes independently addressable printing element data channels and a data distributor allowing interleaving to be accomplished in the printhead. The printhead also includes pixel replication circuitry that allows pixel replication in both the fast and slow scan directions.

International Classification:

G01N 2155
G01J 102

US Classification:

356448

Abstract:

A method is disclosed for calibrating a reflectometer using black and white references observed in locations optically different from the sample location. Dark and light standards are selected to have reflectance values, while examined in the detection location of the test elements, that are within. +-. 005 and. +-. 05 of the values of the black and white references, respectively, when examined in a location displaced from the detection location of the test elements. Such standards are then read on a referee reflectometer having "ideal" black and white references, and the reflectances so read on the referee reflectometer are recorded for use as calibrating factors in making reflectance readings for the test elements.
