Title: Distortion penalty measurement procedure in optical systems using noise loading
Inventor: KHALEGHI FARIDEH
IPC: H04B10/08
Filed: 1998-08-27
Abstract: The BER is used as a parameter for evaluating the performance of an optical transmission system. Performance of optical systems is also defined by the Q factor, which uniquely determines the BER in the absence of distortion. The measurements are effected in a point of operation of the channel which gives a value of interest for the Q factor. To this end, the optical SNR is lowered by adding noise over the information signal. A distortion-free Q (Q DF) and a back-to-back Q (Q BB) are determined in the same operating point of the system. The distortion penalty for transmitter-receiver pair may be determined by comparing Q DF to Q BB The noise loading technique will allow to investigate if equalizing. The value of OSNRs at the output of a particular system results in equalizing the noise margin in that systems or not.

Title: Process for the production of liquid pig iron or liquid intermediate products of liquid steel and spongy metal
Inventor: SCHREY GUENTER
IPC: C21B13/06
Filed: 1997-03-03
Abstract: The invention relates to a process for the production of liquid pig iron (16) and spongy metal from materials made from iron ore (4), or another metal ore.  During said process the materials used are directly reduced in at least a first reduction zone (2) to form spongy iron, the spongy iron is melted in a meltdown-gasification zone (15), with supply carbon carriers (10) and oxygen-containing gas, and a reduction gas containing CO and H2 is produced and conveyed into the first reduction zone (2) where it is reacted and removed as top gas. After washing, said top gas undergoes CO2 elimination, and optionally heating, is conveyed as an at least extensively CO2-free reduction gas to at least one other reduction zone (27) for direct reduction of metal ore, in particular of iron ore (26), and after reaction with the iron ore (26) is removed as export gas and cleaned in a scrubber. To use the minimum amount of energy when utilising the sludge in the scrubbers, the water is removed from the sludge which occurs when the top gas from the first reduction zone (2) is washed, and said sludge is poured into the meltdown gasifier (15). In contrast, the water is removed from sludge which occurs when the export gas of the other reduction zone (27) is washed, and said sludge is fed into the first direct reduction zone (2).

Title: Rom-based finite impulse response filter for use in mobile telephone
Inventor: EASTON KENNETH D
IPC: H03H17/06
Filed: 1997-06-23
Abstract: The finite impulse response (FIR) filter (20) is implemented as a table (104) using read-only memory (ROM). The FIR filter table stores a pre-calculated output filter value for each permissible combination of input values (102) to be filtered. Streams of input values are successively shifted into the table using a shift register (106) and corresponding output values are successively output. The telephone employs a data burst randomizer (18) to provide a data signal composed of sequences of null or 0 values and sequences of antipodal values (+1's and -1's). Hence, the permissible input combinations for the FIR filter include only patterns containing either all antipodal signals, all null signals, leading antipodal signals followed by trailing null signals, or leading null signals followed by trailing antipodal signals. The FIR filter look up is configured to exploit these limitations on the input streams yielding a look up table having relatively few entries.

Inventor: STARODUBOV DMITRY S
IPC: G03C5/16
Filed: 1997-12-30
Abstract: A grating (12) is induced in the core (14) of a hydrogen-loaded high-germanium-content optical fiber (10) using near-UV (275 nm-390 nm) laser light (40). An interference pattern is generated at the core (14) using a molded polymer phase mask (30) with a square wave surface relief pattern (34). The light (40) is directed through the phase mask (30), through a protective fiber coating (18), through the cladding (16), and into the core (14). The phase mask (30) generates an interference pattern with a period half that of the surface relief pattern (34). Index of refraction changes occur at the bright fringes of the interference pattern, thus creating the grating. Advantages over existing mid-UV technology include lower fabrication costs for phase masks, simplified grating induction since fiber coatings do not need to be removed, and reduced infrared absorption caused by grating formation in the fiber.
