Publication number: 20200042279Abstract: Media content can be created and/or modified using a network-accessible platform. Scripts for content-based experiences could be readily created using one or more interfaces generated by the network-accessible platform. For example, a script for a content-based experience could be created using an interface that permits triggers to be inserted directly into the script. Interface(s) may also allow different media formats to be easily aligned for post-processing. For example, a transcript and an audio file may be dynamically aligned so that the network-accessible platform can globally reflect changes made to either item. User feedback may also be presented directly on the interface(s) so that modifications can be made based on actual user experiences.Type: ApplicationFiled: October 11, 2019Publication date: February 6, 2020Inventors: Steven Surmacz Rubin, Ulf Schwekendiek, David John Williams

Publication number: 20180173388Abstract: Different types of media experiences can be developed based on characteristics of the consumer. “Linear” experiences may require execution of a pre-built script, although the script could be dynamically modified by a media production platform. Linear experiences can include guided audio tours that are modified or updated based on the location of the consumer. “Enhanced” experiences include conventional media content that is supplemented with intelligent media content. For example, turn-by-turn directions could be supplemented with audio descriptions about the surrounding area. “Freeform” experiences, meanwhile, are those that can continually morph based on information gleaned from a consumer. For example, a radio station may modify what content is being presented based on the geographical metadata uploaded by a computing device associated with the consumer.Type: ApplicationFiled: December 7, 2017Publication date: June 21, 2018Inventors: Ryan Terrill Holmes, Steven Surmacz Rubin, Ulf Schwekendiek, David John Williams

Patent number: 9329508Abstract: The method of manufacturing toners disclosed herein includes a continuous temperature ramp and coalescence process that involves continuously passing toner slurry, such as an aggregated toner slurry, through at least one heat exchanger before being subjected to a cooling step. The heat exchanger is pressurized, so the temperature of the slurry may be increased above the atmospheric boiling point of water without boiling the water component of the slurry. Because of these higher temperatures, the coalescence step can be completed more quickly than in conventional batch processes. More than two heat exchangers may be connected in the coalescence step, yielding multiple ramping/cooling temperature steps, ability to inject components, or recycling heat from the process to reduce energy consumption.Type: GrantFiled: March 26, 2013Date of Patent: May 3, 2016Assignee: XEROX CORPORATIONInventors: David John William Lawton, David R. Kurceba, Frank Ping-Hay Lee, Daniel McDougall McNeil, Santiago Faucher
