Publication number: 20070067707Abstract: Synchronous digital ink and audio annotations of media data stream. A media data stream is rendered. The media data stream includes media data organized in one or more segments. Annotating data is received from a user for annotating the media data. A time is identified when the annotating data is received. The identified time is relative to a time corresponding to the one or more segments of the media data as the media data stream is being rendered. An annotating data stream is organized to include the annotating data synchronized with the media data stream based on the identified time. A new file is created that includes the original media data stream and the annotating data stream, or the annotating data stream is added to the original file and saved to a storage area.Type: ApplicationFiled: September 16, 2005Publication date: March 22, 2007Applicant: Microsoft CorporationInventors: James Travis, Michael Wasson

Patent number: 4093612Abstract: Certain compositions have been prepared by the reaction of certain dyes of the class generally known as Color Index reactive dyes with certain support phases. The dyes utilized for said compositions all possess the general sulfanilido-triazidinyl-sulfoaryl group wherein the aryl groups may be phenyl or naphthyl and said general group is further bonded to aryl groups via an amino or azo linkage. It has been found that when aqueous fluids containing albumin, such as, for example, plasma or serum are passed over compositions within the scope of the present invention albumin is selectively adsorbed on said compositions without removal of other proteins present in the fluid. It has further been found that the albumin may be readily removed from the thus formed adsorbate without denaturing the albumin and leaving the solid phase dye composition in a suitable state for re-use without loss of activity.Type: GrantFiled: February 27, 1976Date of Patent: June 6, 1978Assignee: Research CorporationInventors: James Travis, Ralph Pannell
