Title: The interactive method for re-selecting the operation network by the wireless area network wlan user terminal
Inventor: ZHANG HAI
IPC: H04L29/06
Filed: 2005-01-21
Abstract: The interactive method for re-selecting the operation network by the wireless area network (WLAN) user terminal, the method comprises the steps as follows:  a. When the WLAN user terminal had been connected to a access communication operation network requires the new selection for accessing another access communication operation network, the WLAN access network sent the certification request of said WLAN user terminal to the home network of the said WLAN user terminal through the another access communication operation network that was accessed by the new selection; b. After the home network of said WLAN user terminal received the authentication certification request, it authenticates the authentication certification request from the access communication operation network re-selected by the WLAN user terminal, and sent the operation indication to the WLAN access network via the access communication operation network; c. After the WLAN access network received the operation indication, it completes the cut-off and the access operation between the WLAN user terminal and the corresponding access communication operation network based on the operation indication. The method enables it to re-select another access communication operation network after the user terminal had accessed an access communication operation network.

Title: Method and apparatus for suctioning and refeeding gastric juices
Inventor: MOSS GERALD
IPC: A61M1/00
Filed: 2006-08-03
Abstract: A decompressing and feeding method and system for safely feeding in the gastrointestinal tract of a recovering patient may continuously aspirate from the stomach and/or other portions of the digestive tract and feed at a rate commensurate with the ability of the intestines to absorb fluids including nutrient. Air is also aspirated in the process so that neither air nor excess fluids cause distension in the gastrointestinal tract. An aspirate including digestive juices and nutrients from the stomach may be filtered and continuously refed together with unused feeding material into the gastrointestinal tract at a location that more efficiently moves and digests the food.

Abstract: Techniques for performing data detection and decoding in a manner to account for guard subbands are described. A receiver obtains received pilot symbols for pilot subbands and received data symbols for data subbands. Channel estimates are derived based on the received pilot symbols with zeroed-out pilot subbands filled with zeros. Data detection is performed on the received data symbols with the channel estimates to obtain data symbol estimates.  Estimates of noise and estimation errors due to the zeroed-out pilot subbands are derived. LLRs are then computed based on the data symbol estimates, the channel estimates, and the estimates of the noise and estimation errors. The LLRs are deinterleaved and decoded to obtain decoded data.

Title: Method and apparatus for using multiple modulation schemes for a single packet
Inventor: AGRAWAL AVNEESH
IPC: H04W72/04
Filed: 2005-12-21
Abstract: Techniques for using multiple modulation schemes for a single packet are described. Each data packet is processed and transmitted in up to T blocks, where T > 1. Multiple modulation schemes are used for the T blocks to achieve good performance. A transmitter encodes a data packet to generate code bits.  The transmitter then forms a block of code bits with the code bits generated for the packet, determines the modulation scheme to use for the block (e.g., based on a mode/rate selected for the packet), maps the code bits for the block based on the modulation scheme to obtain data symbols, and processes and transmits the block of data symbols to a receiver. The transmitter generates and transmits another block in similar manner until the data packet is decoded correctly or all T blocks have been transmitted. The receiver performs the complementary processing to receive and decode the packet.

Abstract: L'invention concerne un procédé et un service de création et de conservation d'une copie instantanée virtuelle de données source dans une unité de stockage source. Le procédé/service consiste à recevoir au moins une demande pour créer une copie instantanée des données source. Néanmoins, au lieu de créer une copie des données source, l'invention consiste à créer une table de mappage d'unités de stockage cibles dans une unité de stockage cible ou dans d'autres unités de stockage gérées par le même système de stockage. Ladite table de mappage d'unités de stockage cibles contient des pointeurs vers les données source. De plus, l'invention consiste à conserver un espace de modification dans l'unité de stockage cible ou dans d'autres unités de stockage gérées par le même système de stockage. Chaque partie de l'espace de modification est associée à une unité de stockage cible donnée. L'espace de modification stocke uniquement des modifications apportées aux données source qui sont uniques pour l'unité de stockage cible correspondante. La table de mappage d'unités de stockage cibles est modifiée lorsque les données sont écrites dans l'espace de modification par redirection des pointeurs correspondants dans la table de mappage d'unités de stockage cibles, des données source vers l'espace de modification.
