Title: Locating method for accident in transmission line
Inventor: OGAWA MASAHIDE
IPC: G01R31/08
Filed: 1989-01-24
Abstract: PURPOSE:To make a passway close to an actual transmitting way by deciding existence of an accident in the manner of detecting the change of conditions at the time of present sampling and at the time of the preceded sampling for a signal obtained from a current detector. CONSTITUTION:Electric waves on transmitting ways 2 of each phase between each way are detected respectively by current detectors 4 and these detected signals are supplied to delay circuits 8 and comparator 9 for the corresponding phases in accident deciding devices 7. Inputted current signals are delayed by a specified time in the circuit 8, then in the comparators 9, the change of condition for the signals at the time of present sampling (n+1 cycles time) and the signals at the time of preceded sampling (n cycles time) which are given through the circuit 8, is detected by means of taking the difference between both signals. At this time, the difference is zero if no accident occurs, but when the accident occurs, a waveform change of the signal is generated and the difference between both signals comes to be zero, thereby the accident is decided as being on occurrence.

Title: Radio receiver
Inventor: SUOMINEN EDWIN A
IPC: H04B1/10
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To obtain selectivity of high quality at low cost for plural passbands to be remarked by adding digital filtering processing, without changing analog signal processing. SOLUTION: A conventional analog down converter 100 converts an RF signal from an antenna 20 into 450kHz IF frequency. The analog filtering in such a case is in charge of basic bandwidth and the maximum elimination of over 50% signal elimination of a receiver. An A/D converter and a dither generator 200 convert it into a sampling digital signal. Next, a digital down converter section 300 converts it into a baseband in a considerably high sampling rate in comparison with the bandwidth of a receiving signal. With this, quantization noise energy is dispersed over a broad frequency spectrum. An additional digital filtering section 400 regulates the selectivity of the receiver to an operation mode whose bandwidth is narrower.
