    • A liquid monitoring device includes means (22, 24) for detecting the presence of a liquid and means (34, 32) for giving an alarm when the liquid is detected. Preferably a temperature sensor (26) is also provided and the temperature is displayed on an LCD (14). The temperature sensor (26) is arranged to sense the ambient air temperature at a first sampling rate and then the liquid temperature, after the liquid has been detected by means (22, 24), at a second, more frequent sampling rate. The components are housed in a casing (10) which carries a pivotably mounted sucker (6) for attachment to a wall or bath.

    • An electro-therapeutic device comprises an elongate hand held casing (1) having a tip electrode (4) at one end and an electrode (11) along one side. The tip electrode (4) is placed against the body and a high voltage (40 to 90V) is passed between the electrodes to stimulate the body at low resistance or acupuncture points. In a first aspect of the invention a low voltage DC current passes through the body and changes in the resistance of the body are used to modulate an audible signal to indicate when a low resistance point is reached. In a second aspect the casing (1) is of elongate cross-section so that electrode (11) sits snugly in the web of the hand. In a third aspect of the invention a pulsed, bi-polar waveform is applied to the electrodes to avoid electrolytic action in the body. A solid state (transistor/diode) switch is also described for connecting the electrodes across a secondary winding of a transformer during a stimulation mode.
    • 电疗治疗装置包括细长的手持式外壳(1),其在一端具有尖端电极(4)和沿着一侧具有电极(11)。 尖端电极(4)抵靠身体放置,电极之间通过高电压(40〜90V),以低电阻或针刺点刺激身体。 在本发明的第一方面中,低电压DC电流通过身体,并且使用身体电阻的变化来调制可听信号以指示何时达到低电阻点。 在第二方面,壳体(1)具有细长的横截面,使得电极(11)紧密地坐在手的腹板中。 在本发明的第三方面中,将脉冲的双极波形施加到电极以避免在体内的电解作用。 还描述了固态(晶体管/二极管)开关,用于在刺激模式期间将电极连接在变压器的次级绕组上。
