Title: Differential psk signalling in cdma networks
Inventor: HO JIN-MENG
IPC: H04B1/707
Filed: 1997-08-21
Granted: 2001-08-14
Abstract: A method and a system for detecting a user signal in a CDMA network. (Coded) user message bits are grouped into successive groups. A differential phase is generated for each message bit group by mapping each message bit group on to a predetermined PSK constellation. An absolute phase is generated for each message bit group based on the differential phase for the current message bit group and the absolute phase for the preceding message bit group. The absolute phase signal is phase keyed to an RF carrier to form an RF signal. The RF signal is spread using two code sequences and the spread RF signal is transmitted. At the receiver, the RF signal is received and non-coherently demodulated. The demodulated RF signal is despread using the codesequences. Successive blocks of the demodulated, despread RF signal are phase compared for extracting the differential phase signal carrying the (coded) user message.

Title: Enzyme additives for ruminant feeds
Inventor: SEWALT VINCENT J H
IPC: A23K1/165
Filed: 1996-07-05
Granted: 2001-11-27
Abstract: Fibrolytic enzyme supplements for increasing the digestibility of legume forages and grain feeds for ruminants, a method of treating legume forages and grain feeds with fibrolytic enzymes, and feed compositions consisting of feed materials treated with a mixture of fibrolytic enzymes are provided. The enzyme supplements do not pre-digest the feed material but assist in the colonization of feed particles in the rumen by ruminal microbes. The fibrolytic enzyme supplements consist of mixtures of cellulase and xylanase in certain preferred ratios and levels which are dependent on the feed material to be treated. The cellulase and xylanase are dissolved in a buffer solution and sprayed onto dry legume forages or grain feeds. The feed material is then incubated for at least three hours to allow the enzymes to be absorbed into and adhere to the feed material. The resulting feed compositions remain stable for at least one year against pre-digestion. When cellulase and xylanase are applied to legume forages and grain feeds in certain ratios, levels and in accordance with the methods of the present invention, synergistic effects between the enzymes occur, providing large improvements in digestibility of feed materials at low enzyme levels.

Abstract: A fuel pellet and a method of manufacturing a fuel pellet capable of burning in either a stoker or pulver furnace, comprising from about 0 to about 80% by weight of cellulosic material, from about 1% to about 50% by weight of densified thermoplastic material, and from about 0 to about 50% by weight of coal. The cellulosic material, densified thermoplastic material and coal are ground from about 80 Mesh to about 200 Mesh, and then blended into a mixture wherein the contents are evenly distributed throughout. Following the blending process, the mixture is forced through a pelletizer. As the pellets are removed from the pelletizer they are immediately cooled so that the densified thermoplastic particles do not melt. The resulting fuel pellets produce from about 10,000BTU per pound to about 16,000 BTU per pound and leave an ash deposit of about 0 to about 6% by weight, and a sulfur dioxide output of about 0 to about 3% by weight.

Filed: 1998-07-28
Granted: 2002-10-22
Abstract: A latching device is provided for coupling a vehicle tool carrier with a variety of tools such as a bucket. The device serves to releasably secure the tool with the carrier once the carrier has been positioned with the tool. A detent mechanism is provided on the device to retain it in either its latched or unlatched position. A lost-motion connection is provided between the latching handle and latch pin to permit the link interconnecting the handle and pin to move to an over-center position when the device is in the latching configuration. A spring serves to hold the link in its over-center position. The latch handle swings through an angle of approximately 70 degrees as it moves between its latched and unlatched positions to minimize interference with the carrier and tool structures and simplify activation by the operator from his seat.

Abstract: Deux techniques de compression de bande vocale connexes sont utilisées afin de permettre l'adaptation d'un système de télécommunications HF avec des signaux de données de modems en bande vocale haute vitesse et de télécopieurs. Un codeur-décodeur haute vitesse permet au système de télécommunications de passer les transmissions par télécopie et modem en bande vocale jusqu'à 9,6 kb/s. Un codeur-décodeur ultra haute vitesse supporte des transmissions par télécopie et modem en bande vocale jusqu'à 14,4 kb/s. Le codeur-décodeur haute vitesse fonctionne au moyen de trois créneaux HF 16 périodes ou quatre créneaux HF 8 périodes, et le codeur-décodeur ultra haute vitesse fonctionne à l'aide de quatre créneaux HF 16 périodes. Du fait que ces codeurs-décodeurs transmettent des informations sur plusieurs créneaux HF pouvant être contigus, les créneaux dans les canaux de communication HF sont affectés de manière dynamique. La fonction d'affectation dynamique des créneaux temporels/largeurs de bande détecte et contrôle la transmission de données et forme un canal de données à partir du nombre nécessaire de créneaux.

Abstract: A low power, multi-cellular, broadband communication system for the unidirectional (i.e. broadcast), bi-directional and multi-directional transmission and reception of voice, video, audio, television and data signals is provided within the context of a point to multipoint network topology. The system incorporates modem, modulator and demodulator elements that operate over the complete licensed band of the operator. In addition, the microwave transmitter, receiver and transceiver elements also operate over the licensed band of the operator, thereby achieving a broadband microwave infrastructure coupled with a flexible modem (modulator, demodulator) architecture that allows flexible channelization at the systems level. The system may operate over two or more separate frequency allocations, such as a downstream frequency allocation at 24 GHz coupled with an upstream frequency allocation at 36 GHz. This is possible because the partition of cell-site receiving and transmitting functions and the use of subscriber antennas that do not have equivalent transmitter/receiver patterns. This allows for different numbers and different types of receiver or transmitter cell-sites to be implemented.  The use of advanced subscriber antenna technology allows for primary and secondary cell-sites to be defined for specific subscribers, thus providing route diversity to combat rain attenuation and rain outage effects, which are the primary cause of outage within the large-area networks operating at frequencies above 10 GHz. The unique system design discussed below allows for route diversity to combat rain and multipath fading effects.

Title: Link aggregation in ethernet frame switches

IPC: H04L45/74
Filed: 1999-07-09
Granted: 2003-04-15
Abstract: Data packets containing source and destination addresses are received on one or more incoming ports for distribution on one or more outgoing ports. An address look-up table stores previously processed source and destination addresses, together with source and destination contexts associated with the respective source and destination addresses. The contexts represent either a specific physical port, or an aggregated grouping of ports. A distribution table stores, for each aggregated grouping of outgoing ports, a corresponding aggregated group of identifiers of specific outgoing ports. As each packet is received, its source and destination addresses are extracted and the address look-up table is searched for those source and destination addresses. If the address look-up table contains those source and destination addresses then the source and destination contexts associated with those source and destination addresses are retrieved from the address look-up table. If the address look-up table does not contain a source address corresponding to the extracted source address, then a source context corresponding to the extracted source address is derived and stored in the address look-up table with the extracted source address. If the retrieved destination address context represents a specific outgoing port, then the received packet is queued for outgoing transmission on that port. If the retrieved destination address context represents an aggregated grouping of outgoing ports, then the identifiers for the outgoing ports comprising that grouping are retrieved from the distribution table, and the received packet is queued for outgoing transmission on all of the outgoing ports comprising that grouping.
