Patent number: 11886367Abstract: An arbitration system receives requests to access a destination during an arbitration window that spans multiple processor clock cycles. During each clock cycle, the destination is monitored to determine whether the destination is suffering from backpressure by receiving more requests than the destination is able to accommodate during the clock cycle. In response to detecting backpressure, a masking index value assigned to a requesting source is incremented, which limits an amount of requests from the source that will be granted destination access during a subsequent arbitration window. Alternatively, in response to detecting an absence of backpressure during an arbitration window, the masking index value is decremented, which increases the amount of requests from the source that will be granted destination access during a subsequent arbitration window.Type: GrantFiled: December 8, 2021Date of Patent: January 30, 2024Assignee: ATI Technologies ULCInventors: Michael E. McLean, Philip Ng

Patent number: 7011021Abstract: A printing blanket sleeve is provided having two separable sections including a carcass sleeve and a face sleeve. The face sleeve is mounted over the carcass sleeve such that, when the printing blanket sleeve is installed on a blanket cylinder, the carcass sleeve and the face sleeve form an integral unit in use. The printing blanket sleeve is provided in separable sections so that the printing surface may be replaced in a manner wherein the carcass sleeve, including preferably at least some portion of the inner layers, can be reused with new printing surfaces. Further, the printing blanket sleeve is arranged such that the user of the printing blanket sleeve can change the printing surface of the printing blanket sleeve on-site so that there is no longer a need to discard the entire printing blanket sleeve, or alternatively send the printing blanket sleeve back to the manufacturer to be reconditioned.Type: GrantFiled: September 10, 2001Date of Patent: March 14, 2006Assignee: Day International, Inc.Inventors: Edward P.

Publication number: 20040045465Abstract: A process of forming a color image element with color-forming photopolymer layer(s), the color image element so formed, and a digital imaging system is provided. A single subtractive working color-sensitive, photopolymerizable layer on a substrate which, upon exposure to an actinic radiation source reflected from a digital light processor accurately reproduces a desired digital color image in the photopolymerizable layer. The use of multiple layers of color specific photopolymers enable a full color image to be formed upon the substrate by this process.Type: ApplicationFiled: September 11, 2002Publication date: March 11, 2004Inventors: Michael E.

Patent number: 6530321Abstract: A flexible image transfer blanket is provided which has a non-extensible backing which is easy to mount onto conventional blanket cylinders, which requires no packing (but which can be used with packing), which does not need to be retensioned during operation, and which prints to the gap better than conventional fabric-reinforced blankets. The image transfer blanket is adapted to be mounted onto a blanket cylinder and includes first and second ends, with at least one of the first and second ends being adapted to be inserted into an axially-extending gap in the blanket cylinder. The blanket includes a image transfer surface layer, at least one woven fabric ply, and a non-extensible base layer. The at least one woven fabric ply includes both warp and weft fibers, with the weft fibers being oriented so that when the blanket is mounted on the blanket cylinder the weft fibers extend circumferentially about the blanket cylinder.Type: GrantFiled: March 15, 2001Date of Patent: March 11, 2003Assignee: Day International, Inc.Inventors: Robert L.
