Abstract: In a wireless 802.15.4 communication system (300), a high-speed data frame structure (340) is provided which uses the 802.15.4 SHR structure that is spread modulated to obtain the synchronization benefits of the 802.15.4 protocol, but which uses a modified data frame structure for the payload portion without using spreading to thereby improve its transmission efficiency. The transmission efficiency can be further increased by increasing the size of the data payload (and correspondingly, the frame length size).

Abstract: A method and an apparatus is provided for producing branch metrics in a LogMAP turbo decoding operation. During a forward recursion of a trellis, a set of primary branch metrics is generated. The primary branch metrics are stored in receiver form in a relatively small memory cache module and corresponding secondary branch metrics are produced by negating the primary branch metrics. The primary branch metrics and the secondary branch metrics constitute all possible branch metrics for a given state in the trellis. During a backwards recursion of the trellis, the stored primary branch metrics are retrieved from the memory cache module and the secondary branch metrics are regenerated by negating the retrieved primary branch metrics.

Abstract: The present invention provides a method for controlling the fate of mammalian cells or microorganisms by the enzymatic formation of intracellular nanostructures. Enzymatic reactions trigger the intracellular self-assembly to convert a proper precursor into another molecule or nanoobject that will aggregate inside cells or inside or between tissues or organs. Further, this invention provides a method for making artificial nanostructures inside or between tissues or organs, by injecting a proper designed precursor into tissues or organs, and enzymatic reaction converting the precursor to a hydrogelator to form artificial nanostructures and inducing hydrogelation and at the state of a disease, another enzyme converts the hydrogelator back to precursor to induce gel-to-sol transition to release a drug. The present invention can be applied to treat diseases caused by the malfunction of cells, infection caused by microorganisms and provides a novel route for controlled drug releases, formation of new therapeutic agents, and in-situ formation of hydrogel to treat degenerative diseases such as osteoarthritis.
