Abstract: An optical waveguide cross-point switch capable of full broadcast and strictly non-blocking operation. The device has a matrix of a plurality of input waveguides and a plurality of output waveguides (MxN). A reflecting surface associated with each intersection may be selectively activated to direct an optical signal on the input line to the associated output line. The reflecting surface may also be employed so as to convert an MxN matrix into a 2(MxN) rearrangeable cross-point switch. Each waveguide is capable of switching a data rate of 10 Gb/s or more. For example, with eight wavelength channels used to impart optical signals to a 16x16 switch a data rate of 1.28 Terabits/second is achievable.

Abstract: La présente invention concerne un procédé de traitement préalable de cultures de myoblaste de donneur sain. Ce procédé utilise des facteurs de croissance ou des facteurs trophiques, tels que le facteur de croissance de fibroblaste basique (bFGF), en cas de transplantation sur des sujets souffrant de dystrophie musculaire telle qu'une myopathie. Grâce à ce procédé, les muscles du receveur renferment une proportion plus élevée de cellules fonctionnelles, ce qui est attesté par une incidence plus importante des fibres dystrophino-positives, de sorte qu'il n'est pas nécessaire de préconditionner les muscles du receveur par irradiation ou administration de toxines. Des myoblastes de donneurs murins exprimant le gène marqueur  beta -galactosidase ont été cultivés dans un milieu contenant du bFGF à raison de 100 ng/ml, pendant au moins les deux derniers jours précédant leur injection dans les muscles jambiers antérieurs (TA) gauches de souris receveuses, compatibles CMH, en l'occurrence des "mdx" ou "modèles animaux de la myopathie de Duchenne". Des myoblastes des mêmes cultures primaires ont été également cultivés sans bFGF et injectés en témoin dans les muscles jambiers antérieurs (TA) droits. Les souris receveuses ont subi un traitement immunodépresseur à base de FK 506. Vingt-huit jours après transplantation myoblastique, la proportion de fibres positives par rapport à la  beta -galactosidase était considérablement supérieure (plus que quadruplée) après culture en milieu bFGF qu'après culture en milieu sans bFGF. Les fibres positives par rapport à la  beta -galactosidase étaient également, dans leur quasi-totalité, dystrophino-positives.

Abstract: A control method and apparatus is provided for isolating network faults via the communication between neighboring network locations and the control of sectionalizing switches at the network locations. Control apparatus is provided at particular network locations which responds to detected fault conditions and communicates the detected fault condition to the control apparatus at neighboring network locations. The appropriate control apparatus, in response to the information received from neighboring network locations, opens a sectionalizing switch to isolate the fault condition. In one particular arrangement, each control apparatus that detects a fault condition sends a signal to appropriate source-side, neighboring control apparatus to inhibit the source-side control apparatus from opening their respective sectionalizing switches. Further, any control apparatus that detected a fault condition and that does not receive an inhibiting signal, controls its sectionalizing switch to open. In a specific arrangement, the control apparatus that opens its sectionalizing switch also sends a signal to predetermined neighboring load-side control apparatus to open their sectionalizing switches, so as to prevent feeding into a fault condition after network restoration via a different path or source.

Filed: 1998-05-20
Granted: 2000-12-26
Abstract: A pseudorandom number sequence generator comprises a bidirectional shift register arranged to be loaded with a multi-bit sequence. The shift register is responsive to an ith clock pulse and an ith direction control bit for shifting the multi-bit sequence in one of two directions, delivering an ith output bit and receiving an ith input bit. The multi-bit sequence successively defines one of nodes of an Eulerian graph connected by branches. A feedback circuit is connected to the shift register for converting a set of input data to a set of output data. The input data comprises a multi-bit sequence stored in the shift register in response to an (i+ 1)th clock pulse, the ith output bit and the ith direction control bit and the output data comprises an (i + 1)th input bit and an (i + 1)th direction control bit. The output data is supplied to the shift register so that multi-bit sequences produced by the shift register move around the graph following every branch exactly once, and outputting the (i + 1)th input bit to form a pseudorandom number sequence.

Abstract: A multiple capillary biochemical analyzer for sequencing DNA and performing other analyses, in which a set of capillaries extends from wells (30) in a microtiter plate (32) into a cuvette (22). In the cuvette (22) the capillaries are held on fixed closely spaced centers by passing through a sandwich construction having a pair of metal shims (64, 66) which squeeze between them a rubber gasket (84) forming a leak        (See formula I) proof seal for an interior chamber in which the capillary ends are positioned. Sheath fluid enters the chamber and entrains filament sample streams from the capillaries. The filament sample streams, and sheath fluid, flow through aligned holes in a barrier member (90) spaced close to the capillary ends, into a collection chamber (102) having a lower glass window (100). The filament streams are illuminated above the barrier member by a laser (130) causing them to fluoresce. The fluorescence is viewed end-on by a CCD camera chip ( 138) located below the glass window ( 100). The arrangement ensures an equal optical path length from all fluorescing spots to the CCD chip and also blocks scattered fluorescence illumination, providing more uniform results and an improved signal to noise ratio.

Abstract: A method of computing a multiple k of a point P on an elliptic curve defined over a field in a processor which generates distinct power signatures for adding and doubling operations, the method comprising the steps of representing the number k as a binary vector of bits k i; forming an ordered pair of points P1 and P2, wherein the points P1 and P2, differ at most by P; and selecting each of the bits k i in sequence. Upon k i being a zero, a new set of points P1', P2' is computed by first doubling the first point P1 to generate the point P1' and produce a first power signature. The points P1 and P2 are added to generate the point P2' and produce a second power signature distinct from the first power signature. Upon k i being a new one, a new set of points P1', P2' is computed by first doubling the second point P2 to generate the point P2' and produce the first power signature. The points P1 and P2 are added to produce the point P1', and produce the second power signature. The doubles or adds are performed in the same order for each of the bits k I, and produce a consistent power signature waveform.

Title: Surface processing of thin film cvd diamond coatings for improved resistive properties and integrated circuit packages incorporating processed coatings
Inventor: FABIS PHILIP M
IPC: C23C16/27
Filed: 1999-01-06
Granted: 2002-04-16
Abstract: A thin film diamond coating and substrate composite is treated in a low temperature plasma processing system with an oxidizing gaseous element.  During the treatment, the oxidative plasma reacts with graphitic surface carbon, resulting in volatile surface molecules which are  pumped off' the diamond; and oxygen in the plasma bonds to diamond carbon to terminate the diamond thin film coating surface.  The process results in a thin film diamond coating having increased resistivity (to at least approximately 101° ohm-cm).  An integrated circuit (IC) package is also provided in which the chip is mounted on a thermally conductive, yet electrically resistive base comprised of a substrate coated with a diamond thin film coating treated according to the above described process of the invention.  Leads are provided in thermal contact with the base, but, due to the electrical resistivity of the base, are electrically insulated from the chip.  Wires between pads on the leads and the chip provide the electrical connection.  The leads provide a direct conduit for thermal dissipation.  The IC package permits increased heat dissipation from the entire package in a manner which does not interfere with its electrical properties and is less expensive to manufacture.
