  • Patent number: 8074595
    Abstract: A method of providing an extruded tire tread (T) with anti-static properties. In this method, a pin (10) is coated with an electrically conductive material (M). The coated pin (10) pierces the tire tread (T) to form an opening (12) of the desired depth and then is withdrawn. During withdrawal of the pin (10), the material (M) remains in the pierced opening (12) so that a conductive body (14) is formed in the tire tread (T). The pin (10) can then be re-coated with the material (M) and the cycle repeated to produce a plurality of conductive bodies (14) in the tire tread (T).

  • Patent number: 5360008
    Abstract: A respiratory monitor (apnea detector) utilizes the discovery that the magnetic permeability of a person's body varies with the respiratory and cardiac cycles. The respiratory and optionally cardiac monitor of the invention includes an oscillator circuit which produces a signal, and a transmitter placed in close proximity of the body of the person (patient) whose respiratory cycle is to be monitored. The transmitter directs and transmits the signal originally generated in the oscillator circuit toward the trunk of the patient. A receiver-transducer is located also in close proximity of the trunk of the patient, and receives the electromagnetic signals which are modulated due to the varying permeability of the body caused by the respiratory and cardiac cycles.
