IPC: G01S13/931
Filed: 2003-02-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a radar device capable of improving resolution of the distance.  <P>SOLUTION: Transmission waves are transmitted from a transmission means 12 to an object 15, and its reflected waves are received as reception waves by a reception means 13. In a conversion means 21, the time difference W1 between the transmission waves and the reception waves is converted into a voltage, and the acquired voltage in this way is subjected to analog/digital conversion by a processing circuit 23, to thereby determine the distance by calculation. Concerning a conversion characteristic for converting the time difference W1 into an electrical signal level, in the first range S12 spreading from the minimum detection distance L1 determined beforehand to the detection requirement distance L2, the rates of change R1, R1a corresponding to the time difference of the electrical signal level are set larger than the rates of change R2, R2a in the second range S23 exceeding the detection requirement distance L2. A value W2 acquired by subtracting a delay time ▵W1 of operation of an electric circuit including the transmission means 12 and the reception means 13 from the time difference W1 is determined, and the value W2 is converted into an electrical signal level.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Voltage sensor
Inventor: INOUE SATORU
IPC: G01R15/06
Filed: 2003-02-26
Abstract: <P>PROBLEM TO BE SOLVED: To improve a voltage sensor for detecting voltages of overhead wires for preventing the sensor from being broken by a partial discharge or an arc discharge of the overhead wires by suppressing the voltage difference between the voltage sensor and the overhead wires.  <P>SOLUTION: The 1st input part of the voltage detector of the voltage sensor is connected with the overhead wire, and the 2nd input part of the same is connected with a detection electrode arranged between the ground and a place adjacent to the overhead wire. The voltage difference detector is prevented from being broken by the partial discharge or the arc discharge from the overhead wire, because the voltage difference detector detects the voltage difference between the overhead wire voltage as a reference and the detection electrode voltage. Therefore, the ground voltage as a reference is not necessary to bring into the voltage difference detector. By this constitution, because the voltage difference detector is arranged adjacent to the overhead wires, the disadvantage of degradation of precision of detection caused by voltages from other overhead wires can also be prevented.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Introducing gradation correction amount in response to degree of variance in gradation value
Inventor: NAGAISHI MICHIHIRO
IPC: H04N5/243
Filed: 2003-03-12
Abstract: <P>PROBLEM TO BE SOLVED: To simply introduce a correction amount for correcting gradation applied to image data.  <P>SOLUTION: A computer PC generates a histogram of gradation values of image data. Then the gradation values are scanned from both ends of the histogram to obtain two gradation values i, j in a way that an area LS at the left end of the histogram and an area RS at the right end of the histogram reach 16% of the total area S of the histogram, respectively. Assuming that the distribution of the gradation values of the image data follows normal distribution, since a range between the gradation values i and j is equivalent twice standard deviation σ, this method can obtain a degree of a variance being an estimate value of the standard deviation. However, all the gradation values of the image data do not follow the normal distribution, the degree of variance includes errors. Thus, the gradation correction amount is obtained by quantizing the degree of variance. Consequently, it is possible to simply introduce the gradation correction amount.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
