International Classification:

H04N 104

US Classification:

358486, 358412, 358404, 358444

Abstract:

A scanner, utilizing a local buffer, prevents the occurrence of stop/start artifacts in the image data by selecting a scan rate that will not overflow the buffer. This is accomplished by having the host computer communicate to the scanner to instruct a modification to a default scanning speed. The modification is based upon an expected rate at which the host computer can consume the image data, prior to the beginning of the document scan. Consequently, the scanner does not generate image data faster than they can be accepted by the host computer, thus avoiding the need to stop the relative movement between the image sensor and the document.

Appl. No.:

10/334621

Inventors:

Timothy Neale - Hampstead NH, US

Assignee:

Wind River Systems, Inc.

International Classification:

G06F015/16
G06F015/173

US Classification:

709/223000, 709/206000, 719/317000, 709/208000

Abstract:

A system and method is described in the context of an AgentX master-sub-agent communication system to provide a registration tree at the master agent having nodes representing one or a range of object identifiers (sub-trees) managed by sub-agents in the system. The master agent receives registration requests from the sub-agents and registers the object identifiers according to an AgentX registration process by adding nodes to the registration tree. The master agent processes SNMP requests by traversing the registration tree to determine the authoritative sub-agent having control of the specified objects. Range information is stored in the tree nodes to reduce storage requirements and increase processing efficiency.

Appl. No.:

9/099158

International Classification:

H04N 146

US Classification:

358505

Abstract:

An autofocus process for imaging optics of a scanner comprises performing multiple scan-line image captures of the document to be scanned. In the preferred embodiment, these captures are of essentially the same scan-line. A focal position of imaging optics, which forms a scan-line image, is adjusted relative to an image detector in between the multiple scan-line captures of image data. In the preferred embodiment, the imaging optics is adjusted. Relay optics or a position of the image detector could alternatively be adjusted. In any case, a focus setting for a subsequent scanning operation is then calculated based on the image data from the multiple scan-line captures. In the preferred embodiment, this calculation yields a lens position for the imaging optics. The invention thus allows autofocussing to the document to be scanned. Problems associated with loss of calibration are avoided.
