摘要： A method for ordered fault clearance visualization in a computer controlled print production device includes receiving data from the print production device operational sensors indicating a possible fault event. Fault analysis is performed to determine whether faults have occurred and to identify the location and type for each fault, based on the data and fault definitions. Identified faults are prioritized, with each fault assigned a unique priority and the order in which the faults are to be cleared is developed. A visualization of the print production device is presented on the graphical user interface, with graphical cues superimposed upon the visualization of the print production device to indicate the fault order, such that a single view presents all identified faults in the system and the fault order in which they should be cleared. The visualization is updated as each said fault is cleared until a no fault state is achieved.

摘要： A fault clearance system and method for a graphical user interface. The system includes a plurality of video objects, each video object corresponding to a respective fault of a reprographic or printing system. Each video object further includes a plurality of video segments corresponding to fault clearance steps. Similarly, a plurality of text objects correspond to respective faults of the reprographic or printing system, and each text object further includes a plurality of text steps, one corresponding to each video segment of the respective video object.

摘要： Alignment system and method for use by pipefitters. A portable hand tool having the appearances of a flashlight and the capability of projecting a collimated, coherent or otherwise directed, highly focused and narrow light beam is provided a coupling device on the end opposite the light emanation end, swivel capability about its elongate axis and bubble-type level devices. A targeting subsystem, for use with the light emanating tool, completes the alignment system. A portion of the targeting subsystem uses a vertically adjustable stand having a bracket useful both for alignment of piping and/or pipe supports, as well as for securing target placards. The target placards are indexed referencing elements that are capturable by the stand bracket or otherwise suspendable pipe straps and brackets (supports). The system lends itself to highly diverse forms of application, in a host of piping and plumbing system installations, and is readily manipulable by a single person.

摘要： The invention is related to construction, namely, discloses a shackle and a locking device comprising said shackle. The technical effect is improving the performance of the device due to a certain design of the shackle. The technical effect is achieved by the fact that the shackle comprises: a first end; a second end, and a plurality of bends between the first end and the second end, thereby forming: a first segment between the first end and a first bend, a second segment between the first bend and a second bend, a third segment between the second bend and a third bend, and a fourth segment between the third bend and the second end, wherein the first segment lies in a first plane and the fourth segment is substantially co-planar with the first segment, and the technical effect is also achieved by design options of the locking device comprising said shackle.

摘要： Alignment system and method for use by pipefitters. A portable hand tool having the appearances of a flashlight and the capability of projecting a collimated, coherent or otherwise directed, highly focused and narrow light beam is provided a multiply threaded end opposite the end of light emanation, swivel capability about its elongate axis and bubble-type level devices. A targeting subsystem, for use with the light emanating tool, completes the alignment system. A portion of the targeting subsystem uses a vertically adjustable stand having a bracket useful both for alignment of piping and/or pipe supports, as well as for securing target placards. The target placards are indexed referencing elements that are capturable by the stand bracket or otherwise suspendable pipe straps and brackets (supports).

摘要： The present invention relates to a printing system, and more particularly to a resource management using job tickets displayed on a user interface for controlling a printing system to generate documents received from one or more input units including a computer network, scanner, modem, etc. Since the operator or user wishes to offer a wide variety of printing options to customers and complete customer orders as quickly as possible, minimizing the interruption of print jobs is a very important priority. By replenishing supplies such as stock and toner in a timely fashion, the utilization of the printing systems can be maximized. In order for the operator to more efficiently utilize the printing system to perform a large number of print jobs with as few interruptions as possible, the present invention provides a user friendly navigational tool, which can provide the operator with information regarding the amount of printing supplies currently available in the printing system.
