Title: Magnetic proximity sensor
Inventor: NISHIO YOSHIAKI
IPC: H03K17/945
Filed: 1993-11-02
Abstract: PURPOSE:To highly accurately correct the output signal of the magnetic proximity sensor into a linear signal in proportion to a distance between an object to be detected and a head. CONSTITUTION:Concerning an oscillation circuit 40, the output signal is changed corresponding to the distance between a head 4 and an object 7 to be detected and outputted through a detection amplifier circuit 41. At the time of correction, when the distance between the head 4 and the object 7 to be detected becomes a prescribed distance, a detection switch 1 is operated, and a signal value inputted to an arithmetic circuit 3 is fed back to a shift span circuit 5. A storage circuit stores corrected values corresponding to the plural kinds of objects to be detected and after the detection switch 1 is pressed plural times, any corrected value corresponding to the value of this output signal is read into the arithmetic circuit 3. At the time of measurement, the linearization correction is performed by calculating this corrected value and the signal inputted to the arithmetic circuit 3.

Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To solve a problem of a conventional image transmitter a supervisory camera of which has had much load, because of many arithmetic quantities required to obtain a difference area. SOLUTION: A current image frame memory 3 stores an image signal from a supervisory camera 1 via an A/D converter 2.

An image signal converter 6 outputs a luminance signal, obtained from the current image frame memory 3 and the reference image frame memory 5 to a sampling section 7, where the image data and the reference image data are sampled. Then a binary processing section 8 compares the sampled data with the reference data for outputting binary processing data to a map arithmetic section 9, which obtains a map value from the binary processing data.  Furthermore, a difference discrimination section 10 decides the difference area, a JPEG compression section 11 compresses the image data in the difference area, and a data transmission section 12 transmits the compressed data.
