Title:
NOISE DIAGNOSIS DEVICE AND DETECTION SYSTEM HAVING SELF-DIAGNOSTIC FUNCTION
Document Type and Number:
WIPO Patent Application WO/2007/066804
Kind Code:
A1
Abstract:
Transformation principle from a physical amount of detection object to an electric
signal is differentiated between first transducer (2) and a second transducer
(3). When the same electromagnetic noise is generated in the atmosphere of the
first transducer (2) and the second transducer (3), noise components included
in signals outputted from the first transducer (2) and the second transducer
(3) have waveforms different from each other, and mixture of noise from the same
noise source can be diagnosed by detecting a signal of different waveform.
