  • Material determination by sweeping a range of frequencies
    Patent number: 10684235
    Abstract: A material-discerning device is arranged to include an antenna, a proximity sensor, a band pass filter and a processor. The antenna radiates a radio-frequency signal and a material object is located in the field created by the antenna and near the proximity sensor. Change in the amplitude of the radio-frequency signal due to the presence of the material object is detected by the proximity sensor. The change in amplitude of the radio-frequency signal is stored. The frequency of the radio-frequency signal is changed and the process is repeated until a range of frequencies have been swept and stored. After the range of frequencies has been swept and stored, the processor determines the type of material of the material object using the results of the changes in amplitude of the radio-frequency signals.

  • Material-discerning sensing by measurement of different points of impedance
    Patent number: 9599739
    Abstract: A material-discerning proximity sensor is arranged to include an antenna that is arranged to radiate a radio-frequency signal. A capacitive sensor is arranged to detect a change in capacitance of the capacitive sensor and to receive the radio-frequency signal. An electrical quantity sensor is arranged to detect a change of the received radio-frequency signal and a change of a radio-frequency signal at an output of the at least one band pass filter.
