Title: Method and device for the production of varying elements
Inventor: DUDZIAK KAI-UWE
IPC: B21D26/037
Filed: 2002-03-06
Abstract: The invention relates to a method and a device for the production of varying elements in a hollow profile, enclosed around the circumference thereof. The device comprises an internal high pressure moulding tool, into the die recess of which a hollow profile blank may be inserted. A branch leads radially off from the die recess, in which the hollow profile blank may be expanded by means of a fluid internal high pressure to form the varying element. According to the invention, varying elements of almost any shape may be formed in the hollow element in a simple and process-secure manner with regard to the moulding process, whereby the device further comprises a membrane and a pressure generator, by means of which the membrane may be pressurised by a pressure medium in such a way that the membrane lies supported against the expanding direction during the expansion of the varying element as said element is formed. The membrane yields elastically on progressive formation of the varying element until the end form is achieved. The membrane is mounted on the tool outside the longitudinal edge of the die recess and stretching across the branching.

Title: Synchronization method and apparatus using a maximum-likelihood principle
Inventor: FAN YIGANG
IPC: H04L27/22
Filed: 2002-05-08
Abstract: The present invention relates to burst mode digital communication systems where data transmission is preceded by a preamble for acquisition of carrier and clock synchronization using maximum likelihood (ML) principle. The optimization algorithms consist of three parts. The first part (Step 1, Step 2) deals with isolating the desired optimal estimate from non-optimal extremes satisfying the same necessary condition, and provides the initial conditions for activating the binary search schemes. The second part (Step 3) performs the binary search for the optimal timing estimate that guarantees the convergence. On the basis of the obtained iterative sequence, the last part (Step 4) constructs a more rapid convergent sequence to obtain the ML symbol timing estimate. Using the obtained symbol timing estimate, the ML carrier phase estimate can be computed explicitly, and synchronization performed.
