Patent CA-2482557-A1 (CA)
Title: Improved apparatus for waste gasification
Inventor: POPE MICHAEL G
IPC: F23G5/16
Filed: 2003-05-16
Abstract: A gasification system that includes a gasification reactor chamber (101) having perforated conduits or an inner lining that increases the exposed surface area of waste materials to gasification conditions, thereby decreasing gasification temperature, time, and cooling period between subsequent gasification procedures. After an aspirator withdraws and oxidizes fuel gas from the reactor chamber, a flare assembly (229b) combusts the mixed fuel gas to provide power or heat to at least one heat recovery device (111). The at least one heat recovery device recaptures thermal energy entrained in the exhaust, thereby reducing exhaust temperature and eliminating the need for an exhaust stack. An absorber purifies the exhaust and an extractor (117) removes carbon dioxide. A portion of the removed carbon dioxide may be used for industrial purposes or for supporting vegetation. At least a portion of the remaining exhaust is returned to the reactor chamber as recycled process gas, thereby completing a closed-loop process.

Abstract: Channel Equalization of a digital TV is disclosed. In channel equalization for restoring an original signal from a digital TV reception signal having passed through a channel, the present invention includes estimating an impulse response of the channel from a received signal having passed through the channel using conjugate-gradient algorithm, finding an equalizer coefficient in a frequency domain using the estimated impulse response of the channel, outputting a signal equalized by multiplying a signal resulting from transforming the received signal into the frequency domain by the found equalizer coefficient, and predicting to remove an amplified noise of the equalized signal using the conjugate-gradient algorithm in a time domain. Accordingly, the variation of the channel impulse response according to time can be tracked in the dynamic channel having fast channel variation as well as the static channel, whereby equalizing performance can be enhanced.
