Title: Signal filtering system
Inventor: HAWARD LEOPOLD A
IPC: H03H21/00
Filed: 1985-10-02
Granted: 1994-11-22
Abstract: An adaptive filtering system is disclosed, which may be used in a digital television receiver to extract low frequency vertical detail information from a comb filtered chrominance signal. This system provides wide bandwidth vertical detail information when the amplitude of the chrominance component of the composite video signal is low and narrower bandwidth vertical detail signals as the amplitude of the chrominance component increases. Adaptive filtering is accomplished by passing the comb filtered chrominance signal through a first low-pass filter (14) and developing two reduced amplitude replicas (21,21) of the filtered signal which are mutually supplementary. The ratio of the amplitudes of these two replicas is variable with a control signal.One replica is passed through a second low-pass filter (22) and combined (26) with the other replica to produce a vertical detail signal. The embodiment of the system that is disclosed includes means (41-46) for developing a control signal that is dependent on the instantaneous amplitude of the chrominance component of the composite video signal.

Patent KR-0177818-B1 (KR)
Inventor: OKUNO KEIZOU
IPC: C04B35/26
Filed: 1991-11-11
Granted: 1999-03-20
Abstract: 본 발명은 자기 특성이 뛰어난 Mn - Zn 페라이트를 단시간에 고능률로 생산하는 기술을 제공하는 것을 목적으로 하고, 실온으로부터 600℃ 까지의 승온시간은 30 분 이상 5 시간 이내로 하는 제1가열 공정과, 600℃ 로부터 소성 온도에 달하고, 필요에 따라 이 소성 온도에서 적당한 시간을 유지한 후, 냉각을 개시할 때 까지의 시간을 10 시간 이내로 하는 제2가열 공정과, 또 냉각 개시 이후 150℃ 까지의 시간을 3 시간 이상으로 하는 냉각 공정으로 이루어지고, 또한 상기 제1가열 공정, 제2가열 공정 및 냉각 공정의 세 공정의 시간의 총 합계를 20 시간 미만으로 함으로써, Mn - Zn 페라이트 압분체를 소성한다.

Title: Thermal recording control method for fax
Inventor: JONG BYONG-DAL
IPC: H04N1/38
Filed: 1991-11-12
Granted: 1994-04-09
Abstract: The method employs a data input unit which receives a line of data from a scanner and a modem, a black pixel counter, a clock generator, a latch unit which latches a line of data and a thermal printer head which selects the 1~4 block and write according to the number of black pixels.
Patent KR-940002853-B1 (KR)
Title: Adaptationally sampling method for starting and finishing points of a sound signal
Inventor: LEE SUN-KON
Filed: 1991-11-22
Granted: 1994-04-04
Abstract: The method adaptively extracts the starting and ending points of voice signals which vary with the environment. The method executes the signal processing (auto correlation (703), pre-emphasis (701), window function (702), voice feature vector extraction, ADPCM) which extracts the interval of voice by a digital signal processor (18). The method includes a statistical parameter extraction process (201) which calculates noise energy level, a starting point extraction process (204) which extracts the starting point of frames, an ending point extraction process (806) which extracts the ending point of frames, and an adaptive extraction process which extracts voice intervals.
