  • Patent number: 8744795
    Abstract: A method for modulating multiple-instruments and multiple-sensors using an electronic device. The electronic device controls an instrument to measure the working parameters of an object, and controls a sensor to detect the working temperature of the object. By comparing the working parameters against a predefined range, and comparing the working temperature against a predefined temperature value, the electronic device determines whether the instrument and the sensor need to be modulated. If any of the working parameters is not within the predefined range or if the working temperature is greater than the predefined temperature value, the electronic device controls the instrument and the sensor to be modulated by using a modulation transfer function and a predetermined direction.
