Title: Multi-carrier arrangement for high speed data
Inventor: TONG WEN
IPC: H04L12/56
Filed: 2001-01-19
Granted: 2012-08-14
Abstract: The system and method of the present invention uses a plurality of carriers by assigning user terminals to the plurality of carriers so that a minimum grade of service is met and so that throughput is maximized. Each serviced user terminal reports the channel quality of each of a plurality of carriers to a servicing base station(s). The reported channel qualities are then converted to maximum supported data rates for each of the user terminals and each of the carriers. These data rates are then used to allocate data service levels and data rates for each of the user terminals so that a minimum grade of service is met for each of the user terminals. Forward link transmissions, e.g., frames/data packets carried on forward channels (F-CHs), are then constructed and transmitted to meet the allocations.

Abstract: A papermaking belt for use in making paper. The papermaking belt, which has a paper-contacting face and a machine-contacting face, may be used in conjunction with a single-wire draw or twin-wire draw of a papermaking machine. The papermaking belt comprises a woven reinforcing element and a patterned framework. The framework defines either or both faces of the papermaking belt, such that a first face of the framework provides at least 90% of the surface area of the paper-contacting face. The pattern of the framework is independent of the weave of the reinforcing element. This arrangement decouples the amount and pattern of the paper-contacting surfaces of the belt from the weave and/or permeability of the belt. Further, this arrangement allows for increased and more uniform contact area of the paper web against a drying cylinder. Additionally, this belt provides an increased wear surface for improved belt life.

Title: Sequentially cross-linked polyethylene
Inventor: DUMBLETON JOHN H
IPC: A61L27/00
Filed: 2003-05-27
Granted: 2008-10-14
Abstract: A method of producing an improved polyethylene, especially an ultra-high molecular weight polyethylene utilizes a sequential irradiation and annealing process to form a highly cross-linked polyethylene material. The use of sequential irradiation followed by sequential annealing after each irradiation allows each dose of irradiation in the series of doses to be relatively low while achieving a total dose which is sufficiently high to cross-link the material. The process may either be applied to a preformed material such as a rod or bar or sheet made from polyethylene resin or may be applied to a finished polyethylene part. If applied to a finished polyethylene part, the irradiation and annealing must be accomplished with the polyethylene material not in contact with oxygen at a concentration greater than 1% oxygen volume by volume. When applied to a preform, such as a rod, the annealing of the bulk polymer part of the rod from which the finished part is made must take place on the rod before the implant is machined therefrom and exposed to oxygen.
