Title: Forwarding information retrieval technique
Inventor: OKAMOTO TSUGIO
IPC: H04L45/74
Filed: 2000-04-14
Granted: 2004-11-30
Abstract: An improved method for retrieving next forwarding destination of a received data signal is disclosed. First, a plurality of first tables and a second table are stored in the retrieval table. The first tables are hierarchically arranged according to division of the destination address, an entry of each of the first tables including a second-table pointer indicating a next accessed second entry of the second table. The second table serves as an index table of the first tables. Each of entries of the second table includes a hop pointer and a first-table pointer indicating a next accessed first table. The second table and a selected one of the first tables are alternately accessed depending on a first-table pointer included in an accessed entry of the second table while retrieving an entry of an accessed first table using a corresponding divisional portion of the destination address. A hop pointer is read from a finally accessed entry of the second table as a retrieval result.

IPC: H05B41/24
Filed: 2000-05-03
Granted: 2003-09-16
Abstract: An electrodeless fluorescent lamp operating at relatively low frequencies (50-500 kHz) whereby a ferrite core is utilized to generate the necessary magnetic and electric fields to maintain the discharge where the core material is Mn-Zn type combination due to its low power losses, 400 mW/cm3, in the frequency range of 50-100 kHz and magnetic field strengths of 150 mT. Furthermore, the material may cover a variety of atomic percentages of Mn and Zn added to Fe2O3 base to obtain favorable grain boundary and crystalline structure, resulting in a practical ferrite core material, having a Curie temperature greater than 200°C. Such material enables the operation of electrodeless fluorescent lamps with powers ranging from 10W to about 250W at low frequencies, as mentioned above, in such a manner that ferrite core losses constitute less than 20% of the lamp power and heat generated by core losses is minimized.

Granted: 2005-08-09
Abstract: A method and apparatus for controlling an equalizer using a sync signal in a digital VSB system is provided, in which the sync signal is accurately separated even though a ghost having a short delay time and a large size is generated, and thus the equalizer is controlled with the separated sync signal. For this purpose, a switching unit is provided between a matched filter and an equalizer, which selects one of two input signals according to a NTSC rejection filter (NRF) on/off control signals and separates a data segment sync signal and a data field sync signal from the selected signal. A  control signal is produced via the separated sync signal to control the equalizer to operate at one mode of a blind mode and a training sequence mode. Since the equalizer performs sync signal separation by using the ghost removed signal, a system initial operational time becomes shorter, and accurate sync signal separation is possible even if severe ghosts occur, to thereby improve degeneration of system performance greatly.
