Title: Method and apparatus for controlling data rate of a reverse link in a communication system
Inventor: NANDA SANJIV
IPC: H04L1/00
Filed: 2004-02-17
Granted: 2019-10-29
Abstract: Various aspects of the invention provide for determining data rate for a reverse link communication by determining packets of data for transmission for a number of communication services, determining a data rate for transmission of the packets of data based on an arrangement of the packets of data in a queue allowing for meeting the transmission deadline for each of the packets of data. The base station determines whether available resources allow for allocation at the base station for transmission from the mobile station at the determined data rate and duration. The mobile station drops at least a packet of data of the packets of data in the queue to determine a new queue of packets of data. The new queue of the packets of data is used to determine a new data rate for communication on the reverse link.

Granted: 2012-10-02
Abstract: A method of seaming an on-machine-seamable multiaxial papermaker~s fabric to prevent yarn migration. The multiaxial fabric (22) is in the form of an endless loop flattened into two layers (40, 42) along fold lines (38). CD  yarns (28) are removed from the folds (38) to create ravel areas. This leaves the MD yarns (26) unbound in the ravel areas. Seam loops (56) are then formed from the unbound MD yarns (26) at the folds (38). A thin porous material (90) is sewn to the fabric at each fold (38). The porous material (90) binds the CD  yarns along the edges of the ravel areas while allowing passage of the seam loops through the material. The laminate prevents migration of CD yarn tails into the seam area.

Abstract: It has been previously disclosed that DNA segments can be made in massivel parallel chemical synthesis operations on a common substrate followed by release of the segments from the substrate and assembly of the segments into target DNA molecules. Here it is taught that if the DNA primary constructs are sufficiently long and properly designed, that the copy numbers of the primary constructs can be multiplied as needed by a PCR process using as a template regions at the ends of the primary constructs. The end regions, called flanking regions, can also be designed so that they may be cleaved easily from the amplification products. The target DNA can then be assembled from the cleaved fragments. Hundreds of thousands of oligonucleotides can be synthesized and assembled into many different individual genes by this process in a relatively quick and efficient process.

Abstract: The present invention relates to compositions comprising Graptopetalum and uses thereof. Graptopetalum can protect animals from liver diseases and medical conditions, such as inflammation, steatosis, and fibrosis. In particular, Graptopetalum inhibits proliferation of activated hepatic stellate cells, which play a pivotal role in liver fibrosis. Graptopetalum also has anti-fibrosis activities as well as inhibits proliferation of lung fibroblasts. Therefore, in addition to being a prophylactic and therapeutic agent for the liver, Graptopetalum is useful against fibrosis or inflammation of tissues or organs other than the liver, in particular lung, kidney, and bladder. Other plants in the family of Crassulaceae, particularly Echeveria, have similar effects as Graptopetalum.
