  • Patent number: 10139396
    Abstract: A method of noninvasively detecting plant pathogenic virus and an electronic apparatus thereof are provided. The method is adapted to the electronic apparatus for detecting pathogenic virus in plants. The method includes the following steps. An excitation light beam is projected to the plant, and a reaction light emitted by the plant in response to the excitation light is received. An analytic optical spectrum corresponding to the reaction light is obtained, and whether the plant has the pathogenic virus or not is determined according to the analytic optical spectrum.

  • Patent number: 7394246
    Abstract: A superconductive quantum interference device (SQUID) system is provided for measuring the alternating current (AC) magnetic susceptibility of material at a single frequency or a mixing frequency from multiple frequencies, such as mf1+nf2, where f1 and f2 are two excitation frequencies of two primary coils. The system includes a magnetic-flux sourcing unit for producing an AC magnetic flux on a sample and a magnetic-flux reading unit for reading the induced magnetic flux from the sample via a magnetic flux transformer. The magnetic-flux reading unit includes a SQUID set for detecting the induced magnetic flux, so as to obtain the magnetic susceptibility of the sample in converting calculation.
