Filed:

Feb 19, 1999

Appl. No.:

09/253192

Inventors:

John C. Barker - Houston TX
Montomgery C. McGraw - Spring TX

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

H04N 132

US Classification:

358468, 382317

Abstract:

A technique is disclosed for programming instructions into a system including a scanning device. The instructions are defined by machine and human readable indicia on an instruction support sheet. A document is associated with the instruction support sheet and may be processed with the instructions. Desired instructions may be selected by annotations on the instruction sheet. The instruction sheet is then scanned to encode the selections. Data sets corresponding to the composition of the instruction sheet are accessed to interpret the selected instructions. Based upon the selected instructions, operations are performed on the document. The operations may include scanning, transmission of facsimiles, transmission of electronic messages, archival storage, and so forth. The instruction sheet may be composed and configured in accordance with needs of individual users. The scanning device may be associated with a computer system or may be a stand-alone device.

International Classification:

H04N 132

US Classification:

358474, 358468, 358 16, 358 18

Abstract:

A technique is disclosed for selectively scanning or encoding a desired region of a document. The desired region is identified via scannable indicia on a control form. The region may be outlined by a border preprinted on the form or traced by a user. Preset selectable regions may be identified by codes or other textual descriptions on the form. The form is scanned and the instructions selected by the user are encoded. The selected region is identified and scanned. Only the selected region is scanned, or a larger region is scanned and extraneous data not corresponding to the selected region is eliminated from the resulting data set. The technique permits elimination of unwanted portions of a document automatically, the reduction in scanned file size, and straightforward handling of batch scanning tasks in which selected portions of documents are to be scanned and processed.

10/034897

Inventors:

John Barker - Houston TX, US
Terry Koh - Singapore, SG

International Classification:

H04L009/00
G06F015/16

US Classification:

713/200000, 709/229000

Abstract:

A process by which a user accesses a web site through the use of a mnemonic associated with the desired site, rather than through the use of the site's actual URL. The mnemonic may be text or an audio or video representation. An on-line service converts the mnemonic to a URL, which then can be used by the user to access the target web site.

Abstract:

A trocar for placement in the lumen of a cannula to facilitate inserting the cannula through tissue is disclosed. The trocar has an improved trigger/obturator assembly wherein the trigger comprises tissue cam parts each having (a) planar outer surfaces, and (b) an arcuate end portion at the distal end of the trigger including a distal edge surface that is arcuate about an axis normal to the outer surfaces. The arcuate end portions intersect at edge surfaces which are obscured by the arcuate end portions.

Abstract:

An improved stapler firing assembly and a surgical stapler are disclosed. The stapler comprises structural members having handle parts with opposite sides and jaw parts projecting from the handle parts. The stapler includes a mechanism for releasable engagement between an elongate locking member and the the structural members comprising a lever lock including a hook portion adapted to pass through a slot in a handle part. The lever lock is mounted on the locking member and includes first and second release buttons and actuating means mounting the first and second release buttons on opposite sides of the locking member for movement between first and second positions with respect to the locking member. The stapler firing assembly comprises a pusher adapted to move longitudinally along one of the jaw parts to sequentially press the staples against an anvil. There is also present a firing handle body having opposite end portions and a mechanism mounting the handle body on the pusher for movement relative to the pusher between a first position and a second position so that the firing handle body can be positioned to be manually engaged on either side of the handle parts to move the second end of the pusher along the second jaw to eject and close the staples.

Abstract:

A multiplexing apparatus for use in a computer system is disclosed. The multiplexing system is typically designed for multiplexing various sources of video signal inputs for subsequent processing. The multiplexing apparatus includes at least one analog video input connector, but preferably has more than one, a programmable signal connector, and a plurality of video output connectors. The programmable signal connector couples to the analog video input connector and selectively multiplexes the analog video input signal. The plurality of video output connectors are further coupled to the programmable signal connector, and they receive the multiplexed video signal from the analog video input connector for processing through at least a first video stream. Additional video streams are also possible for processing for a single input signal.
