Title: Compatible linear and branched ethylenic polymers and foams therefrom
Inventor: RAMESH NATARAJAN S
IPC: C08F2/00
Filed: 2000-09-08
Abstract: An expanded cellular ethylenic polymer product is provided from an irradiated, noncross-linked linear ethylenic polymer. Linear ethylenic polymers can be irradiated at ambient conditions sufficient to introduce branching in the polymer in the absence of detectable cross-linking as indicated by the absence of gels. The irradiated linear ethylenic polymer is compatible with highly branched low density polyethylene and, when mixed therewith, produces a resin having a single broad based melting temperature range as determined by direct scanning calorimetry, which indicates that the polymers in the mixture have similar crystallization behavior suitable for producing low density foams by extrusion foaming. The linear polymers can be obtained from recycled shrink wrap film.  Low densities of from 0.7 to less than 4 pcf can be achieved. The foams typically have improved tear resistance as compared to previous products prepared from low density polyethylene, at comparable low densities.

Filed: 2000-09-21
Abstract: A power source, power converter, and a radio and microwave generator are provided. The power source comprises a cell for the catalysis of atomic hydrogen to release power and to form novel hydrogen species and compositions of matter comprising new forms of hydrogen. The compounds comprise at least one neutral, positive, or negative hydrogen species having a binding energy greater than its corresponding ordinary hydrogen species, or greater than any hydrogen species for which the corresponding ordinary hydrogen species is unstable or is not observed. The energy released by the catalysis of hydrogen produces a plasma in the cell such as a plasma of the catalyst and hydrogen. The power converter and radio and microwave generator comprises a source of magnetic field which is applied to the cell. The electrons and ions of the plasma orbit in a circular path in a plane transverse to the applied magnetic field for sufficient field strength at an ion cyclotron frequency .omega.c that is independent of the velocity of the ion. The ions emit electromagnetic radiation with a maximum intensity at the cyclotron frequency. The power in the cell is converted to coherent electromagnetic radiation. A preferred generator of coherent microwaves is a  gyrotron. The electromagnetic radiation such as microwaves emitted from the ions is received by at least one resonant receiving antenna of the power converter and delivered to an electrical load such as a resistive load or radiated as a source of radio or microwaves. The radio or microwave signal may be modulated during broadcasting by controlling the plasma intensity as a function of time or by controlling the signal electronically.

Title: Procede et dispositif servant a faciliter la synchronisation de stations de base dans un systeme de communications mobile asynchrone amdc
Inventor: LUNDQVIST PATRIK NILS
IPC: H04W92/10
Filed: 1999-02-09
Abstract: L'invention concerne un procédé et un dispositif servant à faciliter la synchronisation (par exemple, les différences relatives connues de synchronisation) de stations de base (BS) (BS1, BS2 et BS3) dans des systèmes de communications mobiles asynchrones AMDC (200). Une pluralité de stations mobiles (MS) (MS1, MS2 et MS3) mesure les différences temporelles relatives entre différentes paires de BS et ces mesures sont mémorisées par ces BS. Une BS de source envoie (106) à une MS, dans un message de liste de voisinage, des évaluations de la différence temporelle relative entre la BS de source et chacune des BS figurant sur la liste de cellules voisines. Chaque BS de la liste peut tenir une table d'évaluation de différence temporelle relative pouvant être mise à jour en continu à partir des rapports reçus depuis les MS. Les BS peuvent ensuite envoyer des entrées extraites de cette table aux MS figurant dans le message de liste de voisinage. Cette nouvelle technique permet d'informer les BS des différences temporelles relatives connues. De ce fait, quand la MS déclenche une recherche de cellule concernant une BS candidate, cette MS possède déjà une évaluation de la synchronisation de cette BS par rapport à sa BS de source. Ce processus de recherche de cellule présente un niveau de complexité plus limité et peut, par conséquent, être mise en application beaucoup plus rapidement que les processus de l'état actuel de la technique. De plus, on peut comparer les évaluations de différences temporelles relatives à des différences temporelles correspondantes mesurées par une deuxième station mobile. Cette comparaison permet de calculer les retards de propagation de signaux entre la deuxième MS et différentes BS afin de déterminer la position de la deuxième MS.

Title: Priority encoder circuit and method
Inventor: MCKENZIE ROBERT
IPC: G11C15/00
Filed: 2000-09-29
Abstract: A system and method for high speed generation of a global address corresponding to the highest priority active matchline sense output signal received after a CAM  search-and-compare operation. A priority encoder having blocks of multiple match resolver circuits arranged in a logical order of priority receives a plurality of active matchline sense output signals. Each block of multiple match resolver circuits generates a flag signal and a local address corresponding to the highest priority active matchline sense output signal received. Control logic receives flag signals from the multiple match resolver circuits, and identifies the highest priority multiple match resolver circuit that has received an active matchline sense output signal. The control logic then disables all lower priority multiple match resolver circuits such that only the local address generated by the highest priority multiple match resolver circuit is passed by the priority encoder. The flag signals are also decoded to provide a logical address of the highest priority multiple match resolver circuit. The passed local address and the logical address of the highest priority multiple match resolver circuit are concatenated to provide the global address of the highest priority active matchline sense output signal received by the priority encoder.
