Filed:

May 15, 2007

Appl. No.:

11/748692

Inventors:

Todd A. Kahle - Hartford WI, US

Assignee:

E-IMAGE Data Corporation - Hartford WI

International Classification:

G03B 21/10

US Classification:

348487, 382114

Abstract:

A digital microform imaging apparatus which includes an approximately monochromatic illumination source transmitting an incident light through a diffuse window along a first optical axis of the apparatus. A microform media support is configured to support a microform media after the diffuse window and along the first optical axis. An approximately 45 degree fold mirror reflects the incident light transmitted through the microform media approximately 90 degrees along a second optical axis. An imaging subsystem includes a lens connected to a first carriage which is linearly adjustable approximately parallel with the second optical axis, and an area sensor connected to a second carriage which is linearly adjustable approximately parallel with the second optical axis.

International Classification:

G03B 21/10

US Classification:

348487, 382114, 358487

Abstract:

A microform imaging apparatus comprising a chassis including a microform media support structure configured to support a microform media within a plane substantially orthogonal to a first optical axis, a fold mirror supported along the first optical axis to reflect light along a second optical axis that is angled with respect to the first optical axis, a lens supported along one of the first and second optical axis, an area sensor supported along the second optical axis, a first adjuster for moving the area sensor along at least a portion of the second optical axis and a second adjuster for moving the lens along at least a portion of the one of the first and second optical axis.

Inventors:

Todd A. Kahle - Hartford WI, US
James H. Westoby - Hartford WI, US

International Classification:

G06F 3/048

US Classification:

715781

Abstract:

A computer implemented method of viewing a microform segment which has been imaged by a digital microform imaging apparatus connected to a computer. The digital microform imaging apparatus images the microform segment and provides a corresponding image data of the microform segment to the computer. The method comprises the steps of: displaying the image data of the microform segment on a display connected to the computer using a computer user interface having a display area; and creating a magnification window within the computer user interface.

Grant Taylor - Harvard MA, US

International Classification:

G06K 9/78

US Classification:

382100

Abstract:

An apparatus for searching for expressions that appear on a microform medium, the apparatus comprising a microform imager including a sensor for generating digital microform images of one segment of the microform medium at a time, a display screen; and a processor programmed to, while the microform imager is generating a digital microform image: (i) use the digital microform image generated by the microform imager to drive the display screen, (ii) search the digital microform image presented via the display screen for instances of a search expression and (iii) visually distinguish the located search expressions in the digital microform image presented via the display screen.

G06K 9/20

US Classification:

382182, 382321

Abstract:

Appl. No.:

7/890054

Inventors:

Todd A. Kahle - Hartford WI

Assignee:

Infographix, Inc. - Sussex WI

International Classification:

G03G 1509

US Classification:

355253

Abstract:

An electrostatic image developer dispenser forms a uniformly thick and uniformly charged layer of developer particles on a transport surface of a conveyor for delivering particles from a reservoir to a development region adjacent to a photoreceptor. A magnet bar assembly inside the tubular conveyor attracts particles to the transport surface for conveyance to the development region. A magnetic doctor blade presents a surface parallel to the transport surface to establish a regulating gap between the doctor blade surface and the transport surface. The doctor blade extends in the transport direction from opposite one pole of the magnet bar assembly toward an opposite pole downstream from the one pole, to concentrate and orient the magnetic field in the particle layer formation area. In one embodiment, the magnet bar assembly has a pole plate opposite from the doctor blade surface and angularly offset therefrom in a direction opposite to the transport direction. In another embodiment, the magnet bar assembly has two pairs of opposed magnets.
