Abstract: A multiplier circuit for use with large numbers is presented. The circuit accepts two large numbers and segments the second number into a number of segments each of a known size. The unsegmented number is multiplied using Booth Encoding by the lowest order segment to form two partial products which are added to form a partial product and an associated carry value. The partial product is shifted right one segment and the result is padded. The next segment is then multiplied by the unsegmented number using Booth Encoding to provide two further partial products for summation. Summation of the three values results in a partial product and an associated carry value. And so the process is iterated until all segments have been multiplied by the unsegmented number. Padding of each partial product is performed based on a flag which is set when a negative encoded number is generated by the Booth Encoding and when a carry out from the sum is not fully resolved. When the flag is not set, the padding is with zeros; when the flag is set, the padding is with ones.

Title: Serum-free, low-protein media for rotavirus vaccine production
Inventor: SEAMANS T CRAIG
IPC: C12N7/00
Filed: 1998-10-23
Abstract: Defined serum-free, low protein media (LPKM), that supports 1) Vero cell growth for up to 20 passages, 2) Vero cell growth on microcarriers and 3) rotavirus production is provided. Maximum cell densities attained are 60-100 % of that in serum-containing medium; the doubling time is equal to that for cells in serum containing medium. Rotavirus titers achieved in LPKM-1 are 50100 % of the serum-containing process. Finally, since LPKM-1 contains no animal-sourced proteins, the problems associated with the serum-containing rotavirus production process (i.e. lengthy wash steps before infection, potential introduction of adventitious agents and lot-to-lot variability) can be avoided while maintaining nearly equivalent product titers.

Filed: 1998-10-28
Abstract: A system, method, and computer readable-medium for performing operations associated with browser requests are provided. The system includes a plurality of dispatchers coupled to a plurality of web listeners. Each of the dispatchers receives from a corresponding web listener browser requests received by the corresponding web listener. The dispatchers are configured to send messages through an inter-machine communication mechanism to cartridge instances. The messages cause the cartridge instances to perform the operations associated with the browser requests. Each cartridge instances includes a cartridge execution engine and a cartridge. The cartridge execution engine handles all inter-machine communication with the dispatchers, and passes the requests to the Lamiides by making calls into the application programming interface of the cartridge. Consequently, cartridges are isolated from the complexities of inter-machine communication, and may therefore be used in a highly distributed system without being distribution-aware.

Abstract: The invention is a cable net suspension floor. It is comprised of the floor slab, masts that the floor slab rests upon, and a cable suspension net that the masts rest upon. The load on the floor is transferred from the slab to the masts. The masts are rigidly joined and perpendicular to the underside of the slab. The lengths of the masts vary in length in a regular manner from longest in the middle to shortest at the outside. The masts form a two dimensional array.  Cables join the bottoms of the masts to each other. The ends of the cables are joined to the masts i.e. the masts are not free to travel along the cables. The cables form a net. The sides of the net are attached to horizontal beams. Thus stress is transferred from the slab to the horizontal beams at the edges of the slab.

Abstract: To determine the channel characteristic of a channel (CHANNEL) between a transmitter (TX) and a receiver (RX), a predetermined periodic signal of pulse amplitude modulated symbols is modulated on waveforms by a cosine modulated filter bank (DWMT MOD) in the transmitter (TX), and the waveforms are transmitted over the channel (CHANNEL). In the receiver (RX), the received pulse amplitude modulated symbols are demodulated from the waveforms by a cosine modulated filter bank (DWMT DEMOD), pairs of the received pulse amplitude modulated symbols are combined to form received quadrature amplitude modulated symbols, and the received quadrature amplitude modulated symbols are divided by the transmitted predetermined pulse amplitude modulated symbols considered pairwise as transmit quadrature amplitude modulated symbols. So, samples of the channel characteristic are generated.

Filed: 1999-07-22
Abstract: A fiber optic cable includes a core and a surrounding protective layer. The core includes an inner tube having one or more optical fibers contained therein, and the surrounding protective layer includes an outer tube received over the inner tube, and a layer of buffer material positioned between the outer tube and the inner tube. The buffer material maintains the inner tube generally centrally located within the outer tube and providing a mechanical link between the inner tube and the outer tube to prevent relative movement therebetween. The inner tube may be coated with a low hydrogen permeability material to minimize the entrance of hydrogen into the inner tube.      The low hydrogen permeability material may be coated with a protective layer of hard, scratch resistant material to protect the integrity of the low hydrogen permeability material. The area in the inner tube not occupied by the optical fibers may be filled with a filler material, the filler material being selected to have a sufficient viscosity to resist the shear forces applied to it as a result of the weight of the optical fibers within the tube while allowing movement of the optical fibers within the tube during spooling, deployment and handling of the cable to thereby prevent damage and microbending of the optical fibers. The filling material may be impregnated with a hydrogen absorbing/scavenging material to remove any excess hydrogen within the inner tube. The optical fibers have an excess length with respect to the inner tube, and the cable may include an outer jacket of a high temperature, protective material to protect the cable during handling and installation.
