Title: Adaptive field or frame store processor
Inventor: NICHOLSON WARREN H
IPC: H04N9/64
Filed: 1986-02-04
Granted: 1994-07-23
Abstract: The signal processor includes a field or frame store (24). If a video signal having a non-standard relationship between its line frequency (fH) and its color subcarrier frequency (fSC) is processed, corresponding signal samples from an analog-to-digital converter (12) of successive fields or frames are misaligned in the store, leading to a degradation of the processed signal. A nonstandard signal detector (22, 19, 23, 21) produces a control signal indicative of the existance of the non-standard relationship and the mode of operation of the processor is controlled accordingly. In one example, field or frame processing and line processing are selectively performed depending on the control signal, line processing being performed in the presence of the non-standard signal.

Abstract: The watt-hour meter adopting the Hall sensor loads the program at power-on. After a V/F converter (3) counts the pulse for a certain time, a displayer (6) displays the present consuming power quantity for 5 seconds with the counted pulse, stores this value into a memory (7). For next 5 seconds, the displayer displays the total consuming power quantity which value is accumulated value of former ones. After repeating these operations 60 times, the maximum value of the total consumed power is displayed and stored in the memory (7) so that the display indicates the present, total, and maximum power consumption. In power failure, an interrupt circuit (5) senses it and stores the data into a nonvolatile memory (7).

Title: Either-way one k time slot exchange circuit
Inventor: OH DON-SONG
IPC: H04Q11/04
Filed: 1990-12-15
Granted: 1993-10-07
Abstract: This is about  the  biredirectional  1K  time  slot  exchange circuit, specially about one which performs the function  of  time slot exchange and concentration in a digital electronic exchanger. The circuit comprises the differential receiver  sect.  outputting at TTL level receiving the channel  data  of  serial  8  bit  from subhighway, a clock selection and  distribution  sect.  outputting the clock  of  distributed  signal,  a  clock  transmission  means providing the differential level of  CP4  and  FS  by  peripherial device, and the  serial/parallel  and  multiple  means  outputting parallel 9bit data in  multiple  and  parallel  transformation  as receiving serial 8 bit data.
