Abstract: A method for hierarchical work scheduling includes consuming a work item at a first scheduling domain having a local scheduler circuit and one or more workgroup processing elements. Consuming the work item produces a set of new work items. Subsequently, the local scheduler circuit distributes at least one new work item of the set of new work items to be executed locally at the first scheduling domain. If the local scheduler circuit of the first scheduling domain determines that the set of new work items includes one or more work items that would overload the first scheduling domain with work if scheduled for local execution, those work items are distributed to the next higher-level scheduler circuit in a scheduling domain hierarchy for redistribution to one or more other scheduling domains.

Abstract: Apparatus for creating powder images. An image forming member and a toner delivery system are supported opposite each other. The images are formed by the image forming member along a first direction. The toner delivery system includes a toner transport for moving toner particles from a supply to a zone opposite the image forming member. The transport moves along a second direction which is non-parallel to the first direction.

Abstract: A toner delivery method and apparatus for delivering highly charged toner containing a minimum of wrong sign toner to a donor roll structure. The donor roll structure, in turn, delivers the toner to an image receiver or a DEP printhead structure. A magnetic brush is utilized for loading toner particles on the donor roll structure. A magnetic cleaning brush is provided for redistributing unused toner on the donor roll structure. The donor roll and magnetic brushes are positioned to form a cavity which is filled with developer material which prevents the formation of carrier bead chains.

Abstract: Direct Electrostatic Printer including a combination toner charging and delivery system. The combination toner charging and delivery system serves to convey well charged toner to an area adjacent an apertured printhead through which toner particles are propelled in image configuration. The system is provided with an annular channel in a generally cylindrical member through which toner laden air moves under pressure. During movement uncharged toner particles collide with a triboactive surface of the channel due to centrifugal force and become charged. The other surface delineating the channel carries a bias electrode thereon. The electrostatic field created by the bias prevents toner from colliding with the triboactive surface once it has reached a predetermined charge/mass ratio.

Abstract: Direct electrostatic printing apparatus including structure for delivering developer/toner particles to a printhead forming an integral part of the printing device. The developer/toner delivery system insures even distribution to an apertured printhead structure. To this end, toner is deposited on a donor belt using a magnetic brush structure. The belt is entrained about a drive roller and an idler roller as well as a stationary mandrel. The mandrel is positioned opposite the printhead structure with a portion of the belt disposed intermediate thereof. The mandrel is provide with a flat area which is coplanar with the printhead structure. The flat area is coextensive with the space occupied a plurality rows of apertures in the printhead to thereby provide a uniform spacing between each row of apertures and the toner delivery belt.

Abstract: A functional testing system for programmable logic devices. Test vectors are generated by a shift register and applied to the contact pins of the logic device through isolation elements so that all pins may be treated alike regardless of whether they are inputs or outputs. The logic level on pins that are outputs are controlled by the logic device, while logic levels on pins that are inputs are controlled by the shift register. The response of the logic device to the test vector is recorded in an output shift register and the response is then shifted out of the shift register to one input of an exclusive OR gate that also receives outputs from predetermined stages of the test vector shift register to create a pseudo-random function. The output of the exclusive OR gate is shifted into the test vector shift register as each bit of the logic device's response is applied to the exclusive OR gate thereby creating a new test vector.

Abstract: A signature analyzer for testing digital circuits. The analyzer includes a memory which is initially programmed with a set of signatures characterizing the digital signals on the nodes of a correctly operating circuit. The nodes of a test circuit are then sequentially applied to a signature generator formed by a multi-stage shift register having the outputs of selected stages fed back to a gate to which the digital signal is applied. The signature generated by the shift register is compared to each of the signatures stored in memory until a signature match is found, thus indicating that the digital circuit, at least as far as the test node is concerned, is operating correctly. The signature generated by the shift register consists of twenty-four bits to provide a probability of error which is comparable to the probability of error in comparing a sixteen-bit signature with the signature from a specifically identified node.
