Title: Toggle for split transaction mode of pci-x bridge buffer
Inventor: KELLY RICHARD A
IPC: G06F13/16
Filed: 2000-03-24
Abstract: A system and method for optimally processing split request transactions across a PCI-X bridge with a PCI-X bridge buffer. The split transaction mode of the PCI-X  bridge buffer is toggled between a No Over-commit mode and an over-commit mode. Over-commitment of the buffer is inhibited when the split transaction mode is toggled to the No Over-commit mode and when the buffer is over committed by the bridge. At least some over-commitment of the buffer is allowed by the bridge when the split transaction mode is toggled to the over-commit mode and when the buffer is not over committed by the bridge. The over-commit mode may be an Over-commitment mode or a Flood mode. The Over-commitment mode allows some degree of over commitment of the buffer by the bridge while the Flood mode allows the bridge to forward all split request transactions regardless of size of the transactions or amount of available space in the buffer when the Over-commit mode is in a Flood mode. The split request transaction is controlled and forwarded based on the toggled split transaction mode. The system comprises at least a toggle switch and a control system. The split transaction mode is toggled to or maintained at a particular mode based on whether a retry or disconnect of the split completion transaction by the PCI-X bridge has or has not occurred and whether the buffer is or is not over committed.

Title: Mobile wood joinery
Inventor: HODGSKISS MALCOLM G
IPC: E04F15/04
Filed: 2000-05-04
Abstract: The durable products of prior art woodworking have always been unyielding constructions of individual wooden elements held rigidly in place by rigid means such as joinery, fasteners, adhesives, or supporting structures. In the present invention a new method of mobile wood joinery alone is used to draw the wooden elements into place while yet allowing them a range of motion. The joinery of the present invention is mobile, resilient, elastic, and dimensionally dynamic and so are the products made using the present invention. In the present invention a width of resilient elastic adhesive is bonded to the adjoining surfaces of the unmilled individual wooden elements of a wooden product. When the adhesive dries, a mobile, resilient, elastic, dimensionally dynamic joint has been formed. This joint can be bent, hinged, stretched, or compressed in many different directions. The individual wooden elements joined using the present invention can move independently of each other. The joint formed by the present invention is inexpensive and easy to form, yet will not be destroyed or loosened by impact during use or by dimensional swelling and contracting of the individual wooden elements it draws together. The individual wooden elements will not be permanently displaced or damaged by impact or by swelling and contracting of the wood, but will always be drawn back to their original correct positions by the mobile joinery of the present invention.

Abstract: On décrit des complexes (vecteurs) ciblés constitués d'un ligand, d'un liposome et d'une molécule thérapeutique qui sont utilisés pour apporter de manière systémique la molécule thérapeutique à divers types de cellules cibles, y compris à des cellules cancéreuses telles que celles de l'épithélioma spinocellulaire de la tête et du cou, et des tumeurs du sein et de la prostate. Les ligands préférés, le folate et la transferrine, ciblent le complexe de liposome et facilitent la transfection du gène transitoire. L'apport systémique de complexes contenant de l'ADN codant le gène p53 du type sauvage à des hétérogreffes établies de souris a manifestement sensibilisé les tumeurs à la radiothérapie et à la chimiothérapie. La combinaison de la thérapie du gène p53 systémique et de la radiothérapie ou de la chimiothérapie classique a eu pour effet la régression totale des tumeurs et l'inhibition à long terme de la récurrence. Ce système d'apport à spécificité cellulaire a également été utilisé in vivo pour apporter avec succès, par administration intraveineuse, de petites molécules d'ADN (oligonucléotides) qui ont induit une chimiosensibilité et l'inhibition de la croissance des hétérogreffes. D'autres molécules thérapeutiques, y compris des virus non transformés, peuvent être encapsulées dans un complexe et ciblées selon l'invention.

Abstract: L'invention concerne un système d'évacuation de fumée utilisé pendant des procédures chirurgicales, en particulier des procédures peu invasives qui impliquent l'utilisation d'un laser ou d'un cautère, au niveau d'un site chirurgical présentant une pression associée plus élevée que la pression ambiante. Ce système comprend un filtre pourvu d'un côté site et d'un côté sortie, et un conduit de fluide qui s'étend entre le site chirurgical et ledit filtre. Ce filtre présente une faible résistance ou une faible chute de pression et résiste à un écoulement fluidique. De ce fait, la pression plus élevée que la pression ambiante n'est pas réduite et génère un écoulement fluidique dans le chemin d'écoulement fluidique, ce qui tend à véhiculer la fumée dans le filtre.

Inventor: FLEURE THOMAS JOHN
IPC: G01V1/00
Filed: 2000-08-23
Abstract: Segmenting the spectral distribution of overlapped vibratory signals improves the efficiency of data acquisition while providing reduced harmonic distortion in the time zones of interest. Two identical sweep segments are used. Each sweep segment includes an earlier low frequency sweep and a later high frequency sweep, the individual sweeps having substantially no overlap in frequency except for tapering. The high frequency sweep in each pair starts before the end of the low frequency sweep with an overlap in time that is selected to avoid harmonics from the low frequency sweep. Correlation of the recorded signal separately with the low frequency sweep and the high frequency sweep gives data sets in which individual portions of the desired data are recoverable with the harmonic distortion largely separated from the desired data. The individual portions of the desired data are then spliced to give a broadband response of the earth. In an alternate embodiment of the invention, groundforce signals or accelerometer signals from the base plate or the reaction mass of the vibrators are measured and filters are derived relating the measured (reference) signals to a desired short duration wavelet. The derived filters are applied to the recorded data and the resulting filtered data sets are combined to give a broadband response of the earth.
