    • The present invention concerns a method of detecting a movement of a timepiece setting stem (1) arranged to be moved axially along and/or rotated about its longitudinal axis. The method comprises: (a) a light source (5) illuminating a portion of the setting stem (1); (b) a light detector (12) receiving a reflected or diffracted light pattern (9) from the setting stem (1); (c) a processor (13) forming a first pixel pattern representative of the reflected light pattern at a first time instant; (d) the processor (13) forming a second pixel pattern representative of the reflected light pattern at a second, later time instant; and (e) determining that the setting stem (1) has been moved, if the second pixel pattern is different or shifted with respect to the first pixel pattern.

    • An RFID transponder chip includes at least one antenna to pick-up and transmit radio-frequency signals, a rectifier to store charge on at least one capacitor at a rectified voltage from the picked-up radio-frequency signals, a power-on reset circuit to maintain a logic unit in a reset state if the rectified voltage level is less than a power-on reset or wake-up voltage of the power-on reset circuit for operating the logic unit. The RFID transponder chip further includes a non-volatile memory, in which are stored one or several trim values. Said non-volatile memory is directly connected to the power-on reset circuit to be able to provide at least one trim value to trim the power-on reset circuit at a rectified voltage level below a wake-up voltage level.
    • RFID应答器芯片包括至少一个用于接收和发送射频信号的天线,整流器,用于在所拾取的射频信号的整流电压下在至少一个电容器上存储电荷,上电复位电路 如果整流电压小于用于操作逻辑单元的上电复位电路的上电复位或唤醒电压,则将逻辑单元保持在复位状态。 RFID应答器芯片还包括非易失性存储器,其中存储一个或多个修整值。 所述非易失性存储器直接连接到上电复位电路,以能够提供至少一个修整值,以在低于唤醒电压电平的整流电压电平下修整上电复位电路。
