Title: Bi-directional electromechanical valve
Inventor: SHIAO YAO-JUNG
IPC: F16K31/05
Filed: 2008-10-03
Abstract: The present invention relates to a bi-directional electromechanical valve, especially used for internal combustion engines, which includes a cylindrical upper cover, two half-cylindrical permanent magnets, two half-cylindrical cases, a set of U-shaped coil, a cylindrical armature, a valve stem, a first spring and a second spring. This designed electromechanical valve can rapidly and strongly open and close in bi-direction. The present invention is an integrated round-shape electromechanical valve which is quite different from the electromechanical valves in other patents. The design of cylindrical mechanism not only reduces the dimensions of the electromechanical valve, but also equalizes the valve wear caused by rotating valve during engine operations. The specially designed cylindrical armature and its button-shaped bottom provide better magnetic force which improves the moving stroke of the armature. With the special designs and arrangements of the single coil set and the permanent magnet sets, the coil volume and needed actuating power are effectively reduced. Besides, the permanent magnets will not be degraded by the magnetic flux of electromagnet. This design also makes the armature stopping at the fail-to-safe top position if there is no electric current applied to the valve. The designed electromechanical valve provides a better driving way for engine intake/exhaust valve system.

Title: Data processing apparatus and method
Inventor: TAYLOR MATTHEW PAUL ATHOL
IPC: H04J11/00
Filed: 2008-10-22
Abstract: A data processor maps input data symbols to be communicated onto a predetermined number of sub-carrier signals of an Orthogonal Frequency Division Multiplexed (OFDM) symbol. The data processor includes an interleaver memory which reads-in the predetermined number of data symbols for mapping onto the OFDM sub-carrier signals. The interleaver memory reads-out the data symbols on to the OFDM sub-carriers to effect the mapping, the read-out being in a different order than the read-in, the order being determined from a set of addresses, with the effect that the data symbols are interleaved on to the sub-carrier signals. The set of addresses are generated from an address generator which comprises a linear feedback shift register and a permutation circuit. A generator polynomial for the linear feedback shift register is R'i[8]=R'i-1[0]⊕ R'i-1[4], and a permutation code is provided for permuting the order of the content of the register stages. The permutation code has been established by simulation analysis to optimise communication performance via typical radio channels. As such, a 1K operating is provided with an interleaver, which can interleave data symbols onto approximately one thousand sub-carriers of OFDM symbols for an OFDM modulated system such as a Digital Video Broadcasting (DVB) standard such as DVB-Terrestrial2 (DVB-T2) or DVB-Cable2.
