Abstract: The present invention relates to detecting the state of a slide block positioned in a linear valve and using the position of the slide block to predict the health of a linear valve and provide information to a controller/monitor. An operator is provided with information before failure occurrence to allow preventative maintenance of the linear valve. The linear valve is constructed with two canister ports and a vent port. The slide block can be constructed to block the two canister ports and vent port simultaneously. The system can control the position of the block, when provided with position information, hence, using the slide block as a shutoff valve. The typical slide valve can be used as an integral slide shutoff valve, reducing system complexity and reducing system weight, which is critical to airborne applications.

Abstract: A network system for printing digital print files, including personal workstations of users and a plurality of printers. The system further includes a print service and a print file storage service, that may be implemented in several ways. A user may submit a print file without specifying a particular printer on which the file must be printed. Then, he can walk up to any of the printers and start the print process for his print file there. In operation, the print service receives the print file, extracts metadata specifying job information from the file, and stores the file in the print file storage service. The metadata of the file are transmitted to the printers, which include the metadata in local print selection mechanisms resident in said printers. The user may select his print file at the operating panel of any one of the printers and start the printing process. In response, that printer fetches the print image data of the selected file from the print file storage service and prints the file.
