Patent number: 9633694Abstract: Video editing methods and systems enable an editor to edit a video project for which source media assets are located at a media storage server located remotely from the editor with substantially the same fidelity and editing feature set that would be available if the source media assets and editor were co-located. A video editing client used by the editor maintains a persistent cache of proxy media with the layers of the video project stored independently, facilitating editing with combinations locally originated assets and remote assets. The client requests frames not already cached from the remote server via a low bandwidth network. Unless a frame is purged from the cache, no frame is requested from the server more than once. A multi-level priority prefetching scheme, including sequence-based prefetching, populates the cache with frames likely to be requested during editing.Type: GrantFiled: April 8, 2016Date of Patent: April 25, 2017Assignee: Avid Technology, Inc.Inventors: Eric Forget, Francis A. Capria, Daniel Desbois, Thomas G. Fincher, Richard Gratton, Stephane R. Harnois, Alan Swartz, Min Wei

Publication number: 20140360947Abstract: A fluid treatment system having an inlet, an outlet, and a fluid treatment zone therebetween. The zone has an array of rows of radiation source assemblies. Each radiation source assembly has a longitudinal axis disposed at an oblique angle with respect to a direction of fluid flow. Each row has a plurality of radiation source assemblies in spaced relation in a direction transverse to the direction of fluid flow, to define a gap through which fluid may flow between an adjacent pair of assemblies. Preferably, all rows in the array are staggered with respect to one another in a direction orthogonal to the direction of fluid flow, such that the gap between an adjacent pair of radiation source assemblies in an upstream row of assemblies is partially or completely obstructed in the direction of fluid flow by a serially disposed radiation source assembly in at least one downstream row.Type: ApplicationFiled: August 13, 2014Publication date: December 11, 2014Inventors: WES FROM, BOYKO M. TCHAVDAROV, MIKE MARCU, RICHARD GRATTON, DAVID OLSON, JIM FRASER, DUSKO A. KEZELE

Patent number: 8507874Abstract: A fluid treatment system having: an inlet; an outlet; and a fluid treatment zone disposed therebetween. The fluid treatment zone has: (i) an elongate first radiation source assembly having a first longitudinal axis, and (ii) an elongate second radiation source assembly having a second longitudinal axis. The first and second longitudinal axes are non-parallel to each other and to a direction of fluid flow through the treatment zone. The present fluid treatment system can treat large volumes of fluid (e.g., wastewater, drinking water or the like); it requires a relatively small “footprint”; it results in a relatively lower coefficient of drag resulting in an improved hydraulic pressure loss/gradient over the length of the treatment system; and it results in relatively lower (or no) forced oscillation of the radiation sources thereby mitigating breakage of the radiation source and/or protective sleeve (if present).Type: GrantFiled: April 2, 2012Date of Patent: August 13, 2013Assignee: Trojan Technologies Inc.Inventors: Wes From, Boyko M. Tchavdarov, Mike Marcu, Richard Gratton, David Olson, Jim Fraser, Dusko A. Kezele

Patent number: 5129667Abstract: A tow connector engageable with a nose strut of an aircraft for towing the aircraft. The connector has an arm and a base extending therefrom with spaced fingers extending from the base parallel to the arm. Each finger has an upper portion which houses a slideable shaft and a notch located at the forward end of each finger for engaging lateral studs on a nose strut of an aircraft. The shafts are slideable between the notches in the fingers and a pair of stops mounted on the base. The tow connector includes an adjustment mechanism having a pin with a head biased upwardly by a spring to protrude above the top surface of each finger adjacent to the rear end of each shaft to maintain the shafts in the forward lock position. A moveable handle is connected to a compression plate to move the heads downwardly to provide clearance to move the shafts.Type: GrantFiled: October 22, 1990Date of Patent: July 14, 1992Inventor: Richard Gratton
