摘要： An electric therapeutic apparatus for inducing an expectoration of sputum by a patient having difficulty therewith by using an interference low frequency wave, which comprises at least one electric current generating unit for generating an electric current having an intermediate frequency, an electric current detecting unit for detecting an electric current when an electric power is supplied, an electric current controlling unit for controlling the current flowing in the apparatus when an electric power is supplied, and at least one pair of electrodes adapted to be attached to a human body, the input of which is connected to the current generating unit. The apparatus can be combined with a separate bioelectric potential measuring unit with a suitable coupling means so that the electric therapeutic treatment can be carried out while checking the bioelectric potential, this unit being, for example, an electrocardiogram, and therefore, if an abnormal bioelectric potential is detected during the electric therapeutic treatment, the current supplied to the therapeutic apparatus is stopped or reduced so that a treatment having a high safety and excellent accuracy can be obtained. Moreover, a fixing device of an electrode in which a plurality of electrodes can be easily fixed to any portion of a human body is provided.

摘要： A wireless transmitting and receiving system includes an ear microphone of the vibration pick-up type for picking up bone-conducted voice signals through an external auditory ear canal wall of a wearer. A portable case is disposed adjacent the wearer's ear and a wireless device is attached adjacent the wearer but spaced from the portable case. A transmitter of a transmitting circuit for transmitting the output signals of the ear microphone is housed in the portable case. A receiver of a receiving circuit is housed in the wireless device and receives signals from outside the system. The transmitting and receiving circuits provide a wireless connection between the portable case and the wireless device permitting two-way communication through one ear of the wearer.
