| A wireless system includes one or more transmitters and one or more remote receivers that are respectively coupled through one or more users and room ground. The transmitters each produce low-frequency, low power signals that, through capacitive coupling, pass as displacement currents into and from the body of the user, which acts as a conductive node. A receiver that couples capacitively to the user responds to the displacement currents and reproduces the signals. The transmitter includes a signal generator and a pair of electrodes. The signal generator produces modulated signals that vary the voltage between the electrodes, a first one of which is closely coupled capacitively to the user's body such that the "quasi-electrostatic" field resulting from the electrode potential causes a displacement current to pass to the user's body. The second electrode is oriented so that its coupling to the room ground is stronger than that of the first electrode, such that room ground acts as a return path for the current from the receiver. The signal generator may modulate the information to be transmitted using, for example, a pseudorandom code, to produce spread spectrum signals. This increases noise immunity and allows multiple transmitters, each using a different modulation code, to operate at the same time. The receivers each include a detector/demodulator that acquires and tracks the signals from the one or more transmitters. | ||||||

| (57)【要約】 無線システムには、ユーザ（１０）及びルーム・アース（１１）を介して結合された送信器（１４）及び受信器（２２）が含まれている。 送信器は、容量結合によって、変位電流としてユーザの身体に送り込まれ、ユーザの身体から送られてくる、低周波低電力信号を発生する。 共用ルーム・アースによって電流の帰路が形成される。 送信器には、内部電極（１８）及び外部電極と、電極間において電圧を変動させる被変調信号を発生する信号発生器（１６）とが含まれている。 内部電極は、ユーザの身体に密接に容量結合されるため、電極の電位から生じる「準静電」界によって、変位電流がユーザの身体に送られる。 外部電極は、そのルーム・アースに対する結合が、内部電極よりも強くなるように配向が施されるため、ルーム・アースが、受信器からの電流のための帰路として働く。 受信器には、同様に、１対の電極（２４、２６）と、さらには、伝送信号を捕捉し、追跡する検出器／復調器（２８）とが含まれている。 受信器電極の一方（２４）は、ユーザの身体に密接に容量結合されるため、身体から送られてくる変位電流が、該電極に送られる。 電流は、さらに、検出回路要素を通って、ルーム・アースに非対称に容量結合されたもう一方の電極（２６）に流れて、電流の経路が完成する。 検出回路要素は、電流を検出し、従来のやり方で、その電流から伝送情報を回復するよう働く。 １つ以上の受信器が、他のユーザによって携行されることもあれば、あるいは、部屋の周囲の固定位置に配置される場合もあり、帰路は、大気と大地アースの組み合わせとすることが可能である。 従って、ユーザは、受信器に物理的に接触して、情報を受け渡す必要はない。 代替案として、コンピュータ・スクリーン上に受信器をアレイをなすように取り付け、キーボード上に送信器を配置することも可能である。 | ||||||

The underground mine communication system comprises a plurality of repeaters and medium frequency radios, including mobile, portable and personal-carried radios, coupled to electrical conductors and natural waveguides existing in the earth by tuned loop antennas. Messages transmitted by the radios are carried to the repeaters by the conductors or coal seam waves.

A paging system, which has a separate set of repeaters, is also coupled to the network of electrical conductors and natural waveguides by tuned loop antennas. The paging system alerts miners to contact the surface base station. Radios, pagers and repeaters in the system are equipped with the intrinsically safe current limiter circuit to preclude the development of incendiary conditions. The current limiter circuit comprises a series arrangement of a current trip circuit, a redundant current trip circuit and a current limiting field effect transistor controlled by a feedback control amplifier. | ||||||
