    摘要: A method and system are described for distributing at least one clock signal between shelves in a multi-shelf modular computing system includes a clock signal generator for generating a first clock signal, an inter-shelf bus for carrying the first clock signal to a second shelf, and a first shelf manager module, associated with the second shelf, for receiving and regenerating the first clock signal and providing the regenerated first clock signal to at least one module within the second shelf. A system and method for detecting a location of a fault in an inter-shelf bus in a multi-shelf modular computing system is also disclosed. A power source applies a bias between at least two conductors of the inter-shelf bus. At least one module detects the applied bias to determine if a fault is located between the at least one shelf and the power source.

    摘要: A method for connecting an externally accessible shared serial port to one of a plurality of target serial ports is provided. The target serial ports are associated with a plurality of different application cards within a shelf assembly. The method includes receiving, from an external device connected to an externally accessible shared serial port, a request for a connection between the externally accessible shared serial port and one of a plurality of target serial ports within a shelf assembly associated with a plurality of different application cards, and determining whether shelf resources are available to connect the externally accessible shared serial port to the requested target serial port. In response to determining that shelf resources are available, the externally accessible shared serial port is connected to the requested target serial port.

    摘要: A modular ink delivery system using ink jet heads effectively supplies ink to a multi-level array of ink jet heads, and ensures that the heads remain in position during printing even if there is vibration of the supporting structures. Delivery is provided by a number of ink containing chambers, at least one for each level and stacked one atop the other. A connection extends from each chamber to at least one ink jet, and ink is automatically supplied to all of the chambers for example by pumping ink to the upper of the chambers, the ink then cascading downwardly from each upper chamber to a lower chamber through standpipe connections between them. The heads are positively held in place by a first circular bar and a second non-circular bar, which bars are operatively engaged by a mounting block for each head for guided movement. A tightenable screw and spring plunger may cooperate with an arcuate bushing for engaging the first bar, and a channel on a releasable clip and rollers on a portion of the mounting block may engage the second bar.

    摘要: A method and assembly varies the image density of ink from a plurality of ink jet nozzles to provide substantially uniform ink density. Electronically and automatically the electrical power consumption of an ink jet device having an electrical heater is measured (typically by measuring the current draw), and in response to that measurement, if necessary, pulse or voltage supplied to the heater or heaters of each of the ink jet devices is automatically adjusted. More electrical power is supplied if greater image density is required for a particular ink jet device, and less electrical power if lower image density is desired. During typical operation all pulse widths are reset to default settings, the signal received is calibrated, a pattern generator is signalled to provided test data, the present peak electrical current consumed by each nozzle heater is sampled, and the pulse width for each nozzle heater is set based upon the current sample.
