    • An information processing terminal is disclosed that is allowed to carry out contactless data transmission or reception with a reading or writing device by use of a magnetic field. The information processing terminal includes a data transmitter or receiver, a signal processor, and a load modulator. The data transmitter or receiver is configured to generate an induced voltage from a magnetic field generated from the reading or writing device at the time of data reception, and send a transmission signal to the read/write reading or writing device at the time of data transmission. The signal processor is configured to generate a response signal based on the induced voltage. The load modulator controls a variable resistance based on the induced voltage and carries out load modulation relating to the transmission signal based on the response signal and the variable resistance.
    • 公开了一种信息处理终端,其被允许通过使用磁场与读取或写入装置进行非接触式数据传输或接收。 信息处理终端包括数据发送器或接收器,信号处理器和负载调制器。 数据发送器或接收器被配置为在数据接收时从从读取或写入装置产生的磁场产生感应电压,并且在数据传输时向读/写读取或写入装置发送发送信号 。 信号处理器被配置为基于感应电压产生响应信号。 负载调制器基于感应电压控制可变电阻,并且基于响应信号和可变电阻执行与发送信号有关的负载调制。
