    • A sensor for measuring moisture content of a sample like hair, comprising: a micorstrip line; a directional coupler having a pair of generally parallel first (3) and second (4) strips defining a coupling gap therebetween; and a high frequency signal generator electrically coupled to said first strip (3) and operable to couple power to said second strip (4) with the sample placed as an overlay across said coupling gap to thereby generate a coupled power signal in said second strip having an amplitude related to moisture content of the sample. The coupled power signal from strip (4) is phase (13) shifted by the microstrip line and coupled to one port of a mimixer (12). The forward power signal from strip (3) is coupled to the other part of mixer (12).
    • 一种用于测量样品样品的水分含量的传感器,包括:微带线; 定向耦合器,具有一对大致平行的第一(3)和第二(4)条,其限定了它们之间的耦合间隙; 以及高频信号发生器,电耦合到所述第一条带(3)并且可操作以将所述样本与所述第二条带(4)耦合,所述样本被放置成跨越所述耦合间隙的覆盖层,从而在所述第二条带中产生耦合的功率信号, 与样品的水分含量有关的振幅。 来自条带(4)的耦合功率信号是由微带线移位的相位(13),并耦合到模拟器(12)的一个端口。 来自条带(3)的正向功率信号耦合到混合器(12)的另一部分。

    • A device (12) for providing an indication of moisture present in skin of a user includes a device body (36) including a skin contact portion (30) . A sensor circuit (42) is located in the device body. The sensor circuit (42) is configured to produce an output signal having a signal value that corresponds to moisture level in the skin with the skin contact portion in contact with the skin at a skin measurement location. A controller (52) is in communication with the sensor circuit and is configured to determine the signal value of the output signal . The controller stores a first signal value in memory corresponding to a first output signal produced with the skin contact portion in contact with the skin of the user at a first skin measurement location. The controller stores a second signal value in memory corresponding to a second output signal generated with the contact portion in contact with the skin of the user at a second skin measurement location different from the first skin measurement location. The first and second signal values are used to indicate moisture present in the skin of the user at the second skin measurement location.
    • 用于提供使用者皮肤中存在的水分的指示的装置(12)包括包括皮肤接触部分(30)的装置主体(36)。 传感器电路(42)位于装置本体中。 传感器电路(42)被配置为产生具有与皮肤测量位置处与皮肤接触的皮肤接触部分相应于皮肤湿度水平的信号值的输出信号。 控制器(52)与传感器电路通信,并被配置为确定输出信号的信号值。 所述控制器将第一信号值存储在与第一皮肤测量位置处与用户皮肤接触的皮肤接触部分产生的第一输出信号相对应的存储器中。 控制器将第二信号值存储在与第一皮肤测量位置不同的第二皮肤测量位置的与用户的皮肤接触的接触部分产生的第二输出信号相对应的存储器中。 第一和第二信号值用于指示在第二皮肤测量位置处存在于使用者皮肤中的水分。
