  • Publication number: 20200019955
    Abstract: A magnetic secure transmission system includes an inductor, a switching circuit connected to the inductor, and a control circuit. The control circuit controls the switching circuit to adjust a level of a current in the inductor by a first amount over a data transmission period, such that the inductor emits a magnetic pulse including a first magnitude during the data transmission period. The control circuit controls the switching circuit to adjust the level of the current in the inductor such that the level of the current is increased and decreased repeatedly by a second amount between two different levels during a data non-transmission period, and the inductor emits a magnetic pulse including a second magnitude during the data non-transmission period. The second amount is less than the first amount, the first magnitude is greater than a threshold value and the second magnitude is less than the threshold value.

  • Patent number: RE47522
    Abstract: The present invention relates to an orthogonal frequency division multiplexing wireless local area network (LAN) transmitting/receiving system for providing expanded service coverage, and a method thereof. A first OFDM modulation is performed for an even-numbered time, and a second OFDM modulation is performed for an odd-numbered time. A transmitting frame including a plurality of signal fields according to the first and second OFDM modulation is transmitted. The receiving system determines whether a signal field is repeatedly generated in the frame. If the signal field is not repeatedly generated, corresponding demodulation is performed. If repeatedly performed, the signal field is demodulated by using first bit allocation information and second bit allocation information having a ½ value of the first bit allocation information. A data field is demodulated according to the demodulated signal field.
