Patent number: 9478146Abstract: A method and system for assessing a student's reading ability is disclosed. An image-capturing device detects, from a worksheet comprising a position-identifying pattern, a first mark in a first region of the worksheet. The first mark is in a first indicator portion of the position-identifying pattern contained within a first indicator region that is associated with a first word. The image-capturing device detects a first note in a note region of the worksheet. Based on whether the first mark, the first note, or both indicates that the first word was read incorrectly or correctly, a processor determines a first reading assessment result for the first word and stores, in a memory, a digital document file comprising the first reading assessment result.Type: GrantFiled: March 4, 2013Date of Patent: October 25, 2016Assignee: Xerox CorporationInventors: Gary W.

Patent number: 8610920Abstract: A system is utilized to view and configure one or more print job scenarios within a print system. A preference module allows a user to select one or more preferences related to a print job in view of a job set and one or more limitations related to hardware within the print system. A rules component creates one or more rules for use within the print system to output a hard copy based at least in part upon the preferences selected via the preference module. A scheduler receives one or more rules from the rules component and configures the print system to execute the print job according to the preferences and/or the rules. A visualizer displays a scenario associated with each print system configuration, wherein the preferences and the rules can be edited to create one or more scenarios for execution of the print job.Type: GrantFiled: April 15, 2009Date of Patent: December 17, 2013Assignee: Xerox CorporationInventors: Saurabh Prabhat, Norman W.

Patent number: 7995225Abstract: A system suited to scheduling print jobs for a printing system includes a first processing component which identifies preliminary attributes of print jobs to be printed on sheets. A job scheduler receives the preliminary attributes and assigns each of the print jobs to one of a plurality of job queues in time order for printing. Print jobs spanning the same time are scheduled for printing contemporaneously. In one mode of operation, the assignment of the print jobs to the job queues is based on their preliminary attributes and on the application of at least one constraint which affects contemporaneous printing of at least two of the plurality of print jobs. A second processing component identifies detailed attributes of the print jobs. A sheet scheduler receives information on the assignments of the print jobs and their detailed attributes and forms an itinerary for each sheet to be printed.Type: GrantFiled: June 7, 2010Date of Patent: August 9, 2011Assignee: Xerox CorporationInventors: Robert M.
