Abstract: According to an aspect of the invention, an information processing apparatus includes an operation acquisition module, a thumbnail image creating module, and a thumbnail image storing control module. The operation acquisition module acquires an operation to an electronic file displayed on a display device, the operation to be acquired by the operation acquisition module being set previously. The thumbnail image creating module creates a thumbnail image corresponding to the acquired operation. The thumbnail image storing control module controls the thumbnail image so as to store the thumbnail image associated with specifying information by which the electronic file is specified.
Abstract: Respective coordinators are spawned or activated to coordinate activities with regard to respective tasks. Where the respective tasks require cooperative efforts of a plurality of controllers, the respective coordinators ensure cooperative efforts by generating and communicating cooperative commands to the plurality of controllers. The coordinators may act as clearinghouses for system data, selectively requesting and relaying system information to appropriate controllers. For example, a document processing system activates respective coordinators for respective sheets of print media. The respective coordinators orchestrate the transportation of the sheets by sequentially orchestrating the activities of sequentially selected pluralities of transportation actuator controllers. Selected sheet position information from sensors and/or from models maintained by the actuator controllers may be relayed by the coordinators to selected actuator controllers as appropriate to the sheet transportation tasks.

Abstract: Exemplary embodiments provide a digital development system and methods for making and using the system. Specifically, the digital development system can utilize a roll member that includes a plurality of actuator cells arranged in a 2-dimensional array with each actuator cell having an actuator membrane individually addressable to eject one or more toner particles adhered thereto. In addition, the digital development system can utilize an imager architecture that includes an addressing logic circuit connected to each cell to selectively control the ejection of the one or more toner particles onto an image receiving member that is closely spaced from each actuator membrane. The disclosed digital development system can be used for non-interactive development systems for image-on-image full-color printing similar to HSD (Hybrid Scavengeless Development) technology with the donor roll becoming a high quality silent imager.
