54323347, Jul 11, 1995

Filed:

Mar 31, 1994

Appl. No.:

8/221331

Inventors:

Steven E. Nelson - Mountain View CA
Robert A. Street - Palo Alto CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G01J 338

US Classification:

2502081

Abstract:

A radiation imaging method and system for use in various imaging techniques includes a source of radiation at first and second wavelengths. A first radiation target array receives the radiation from the first wavelength at first spacial locations to produce an array of output signals at locations within the first radiation target array related to the magnitude of the radiation at each of the first spacial locations. A second radiation target array receives the radiation at the second wavelength at second spacial locations to produce an array of output signals at locations within the second radiation target array related to the magnitude of the radiation at each of the second spacial locations. The first and second outputs are combined to produce combined image signals that has increased contrast from that which would be produced by either the first or the second output alone. In a preferred embodiment, the first and second radiation target arrays comprise amorphous silicon arrays in which sensor data from the first and second radiation targets is synchronously clocked from the array.

Assignee:

Xerox Corporation - Stamford CT

International Classification:

H04N 100
H04N 104

US Classification:

358400

Abstract:

The compact document imager and display apparatus has a two-dimensional image sensor array, a flat panel display such as a liquid crystal display (LCD), and processing electronics. An illumination source can be added to illuminate the document on the sensor array and to provide backlight for the LCD. Color imaging may be achieved by providing three sequential illumination pulses of appropriate colors. A document is placed in close contact with the sensor array. The document is illuminated and an electronic image is captured and stored in the processing electronics. The captured image can be displayed on the LCD by the processing electronics. The document, such as a single sheet of paper or a transparency, can be illuminated by the room light to perform image capture. The compact document imager can be used as a facsimile machines by providing telephone connections. Documents can be scanned using the sensor array and sent to other devices.

Abstract:

An open collaboration approach using an interactive whiteboard appliance is presented. An interactive whiteboard application executing on a computing device causes a first window instance to be generated and displayed on the display of the interactive whiteboard appliance, first data to be processed by the first window instance generated and displayed on the display of the interactive whiteboard appliance, and a second window instance to be generated and displayed on the display of the interactive whiteboard appliance. A data management application is configured to determine whether the first data processed by the first window instance generated and displayed on the display of the interactive whiteboard appliance is compatible with the second window instance generated and displayed on the display of the interactive whiteboard appliance, and cause the first data to be processed by the second window instance.
