Filed:

Nov 20, 2000

Appl. No.:

09/717325

Inventors:

Jian Wen - Irvine CA

Assignee:

Aetas Technology, Incorporated - Irvine CA

International Classification:

G03G 1502

US Classification:

399116, 399118

Abstract:

An imaging system including a plurality of developing stations for developing an image on a sheet, a releasably removable image receiving module having at least one exposing unit and an image receiving substrate and a support structure for receiving the releasably removable image receiving module. The releasably removable image receiving module is configured to engage the support structure of the system such that the image receiving substrate of the module can be disposed in an operative relationship with the developing stations when the removable module is engaged with the support structure. This imaging system provides a method for upgrading, downgrading or modifying the imaging system that could be substantially performed by an end user. This imaging system may be embodied in a monocolor or multicolor printer, copier, facsimile machine or other electrophotographic based apparatus.

Jian Wen - Irvine CA, US

International Classification:

G06F 17/30

US Classification:

707798, 707E17011, 707E1701

Abstract:

Techniques for data assignment from an external distributed file system (DFS) to a database management system (DBMS) are provided. Data blocks from the DFS are represented as first nodes and access module processors of the DBMS are represented as second nodes. A graph is produced with the first and second nodes. Assignments are made for the first nodes to the second nodes based on evaluation of the graph to integrate the DFS with the DBMS.

Assignee:

Aetas Technology Corporation - Irvine CA

International Classification:

G03G 1500

US Classification:

399164

Abstract:

In the embodiment disclosed in the specification, an electrophotographic exposure and development arrangement has a flexible transparent photoreceptor belt driven between two support rollers and along four printing stations at each of which the photosensitive surface of the photoreceptor is charged, exposed to a light image corresponding to a selected color, and developed with toner of the corresponding color to produce a composite multicolor image which is transferred to a substrate and subsequently fixed on the substrate. At each printing station an exposure unit has a curved belt support surface which is engaged by the photoreceptor belt passing through the printing station between the exposure location and a development location with a curvature and length selected to minimize the effect of ripples or irregularities in the position of the photosensitive surface of the photoreceptive belt resulting from a set taken by the photoreceptor belt when held stationery against a supporting number.
