  • Patent number: 10621395
    Abstract: In a configuration for detection of a movement state of a radio tag using a phase difference of a response wave from the radio tag, a phase ?[i] and a measurement time t[i] of a response wave from a radio tag measured are sequentially stored in a memory. A difference from a previous phase and a difference from a previous measurement time with respect to each phase ?[i] stored in the memory are calculated as a phase difference ??[i] and a time difference ?t[i]. A phase addition value ?sum[i] obtained by cumulatively adding a plurality of the phase differences ??[i] is calculated so as to correct a phase difference in which the corresponding time difference ?t[i] among the calculated plurality of the phase differences ??[i] exceeds a time threshold tsa [i], whereby the movement state of the radio tag is detected based upon the calculated phase addition value ?sum[i].

  • Publication number: 20190303631
    Abstract: A configuration which can easily discriminate a moving wireless (radio) tag from a stationary wireless (radio) tag. The configuration uses an antenna to measure phases of response waves received from a wireless tag. Based on the measurements, the configuration measures changes in distance from the wireless tag to the antenna and detects travel of the wireless tag. Based on the measurements, the configuration measures changes in velocity of the wireless tag relative to the antenna. A wireless tag having a rate of changes in signs of the velocity, of not less than a predetermined value in the measured velocity changes, is detected as being a stationary tag.
