Abstract: A system, and a corresponding method, are used to implement rank sparing. The system includes a memory controller and one or more DIMM channels coupled to the memory controller, where each DIMM channel includes one or more DIMMS, and where each of the one or more DIMMs includes at least one rank of DRAM devices. The memory controller is loaded with programming to test the DIMMs to designate at least one specific rank of DRAM devices as a spare rank.

Abstract: The present invention relates to a method and an apparatus for simultaneously assessing the functional status of component parts of the nervous system by presenting sparse stimuli to one or more parts of the sensory nervous system. Sparse stimuli consist of temporal sequences of stimulus conditions presented against a baseline null stimulus condition, where the non-null stimulus condition, or conditions, are presented relatively infrequently. The low probability of encountering a stimulus differing from a baseline or null stimulus condition in sparse stimulus sequences insures that gain control mechanisms within the nervous system will increase the neural response magnitude and also bias the measured responses to those neurone populations having such gain controls. The consequently increased response amplitudes ensure more reliably recorded responses than are obtained with non-sparse stimuli.

Abstract: This invention concerns the detection of neural damage to the optic nerve, optic radiations and white matter of the visual brain indicative of various neurological disorders but with particular application to multiple sclerosis. The method involves simultaneous measurement of the shape and latency of responses to visual stimuli presented simultaneously in different parts of the visual field of the two eyes, separating out linear and nonlinear response components, and most particularly separating out binocular interaction responses to assess neural function within each half of the visual cortex. Because rough retino-topicity is maintained in the optic nerve, through the optic radiations and the visual cerebral cortex, stimulation of the separate parts of the visual field permits isolation of responses from different component parts of these neural elements and therefore from the results obtained an objective assessment of damage to these separate neural components can be made simultaneously.

Abstract: A padding machine (10, 100) is disclosed which is capable of separating materials in a spoils bank beside a trench into coarser materials, which are redeposited in the spoils bank behind the machine, and finer materials which are conveyed to the trench for padding the pipeline. The machine includes a conveyor with a conveyor chain which moves around the perimeter of the machine. Material caught by the scraper blade (28) is conveyed by the conveyor chain along a belly pan (70) and thereafter over a plurality of grizzly bars (72). Coarser material which will not pass through the grizzly bars is conveyed by the conveyor chain (56) to the rearward end of the machine and dumped off the rearward end of the machine back to the ground. The finer materials passing through the grizzly bars are again separated by a vibrator unit (76, 104).

Abstract: A diagnostic test for glaucoma which preferably uses four types of frequency doubled illusion patterns to determine the existence of glaucomatous damage in different regions of the eye. The four frequency doubled illusion patterns are preferably generated on a cathode ray tube by single spatial frequencies in the range of 0.1 to 4.0 cycles per degree whose contrast is modulated in time at between 10 and 50 Hz. As the contrast of each of these patterns is lessened, a threshold value is determined for each pattern at the point where the subject can only discern thick vertical stripes in the test pattern rather than the frequency doubled illusion. By comparing the detected threshold values for the various patterns among themselves and with other test data for normal sighted persons, the presence of glaucomatous damage to different regions of the eye can be detected.

Abstract: A clean air cabinet includes a blower chamber and a sample chamber separated by a filter. A blower within the blower chamber forces air through the filter into the sample chamber. A perforated wall between the sample chamber and the filter provides a pressurized zone between the wall and the filter. An exhaust plenum connects the pressurized zone with an exterior of the cabinet. A cap is provided to close off the plenum when the blower is not operating.

Abstract: Intermixing of line heights in a buffered printer is accomplished by storing a different byte in a forms control buffer for each line of coded character data in a page to be printed. As the coded data of each line is advanced for printing by an arrangement which modulates a laser beam during scanning across a printable medium to effect the printing, the byte within the forms control buffer corresponding to the line about to be printed causes selection of the number of scans of the laser beam to be used in printing the line, thereby determining the height of each line independently of the other lines in the page. Blank lines in the page are formed by channel commands to the printer which instruct an address register associated with the forms control buffer to be incremented to cause skipping to a particular channel number identified by one of the bytes in the forms control buffer or to cause spacing by a specified number of lines.

Abstract: In a printer in which character code bytes representing characters to be printed are translated into graphic code bytes, assembled into lines and pages, and thereafter used to select character image bits which are applied to modulate a scanning laser beam and thereby effect printing of the characters, the pitch of each character is determined independently of other characters in each line being printed by pitch bits included in the sets of character image bits. As each scan line of modulation bits from a set of character image bits is selected for use in modulating the laser beam, the pitch bit included within the bits is examined to determine whether the width of the charactor is to be a maximum or some value less than the maximum. For the maximum width all of the modulation bits are applied to modulate the laser beam, while for a character cell width less than the maximum, only a selected number of the modulation bits are used to modulate the laser beam.

Abstract: In a buffered printer in which lines of graphic code bytes representing characters to be printed are successively advanced to a line buffer where they are sequentially sampled and the results used to modulate a laser beam undergoing successive scans of a printable medium to effect printing of the characters, an arrangement is provided for determining the size of the lefthand margin of the printable medium and the location adjacent the right-hand edge of the printable medium where printing is to be terminated. The arrangement sums count values representing a fixed offset adjacent the left edge of the printable medium and the distance between the end of the fixed offset and the horizontal location of the desired margin as determined by plural panel mounted switches to provide a first count which is carried out beginning with the start of each scan of the laser beam.
