  • Publication number: 20080171929
    Abstract: Standardization between paired electrodes is maintained in a medical device without needing a Mylar spreader, such as by forming the paired electrodes integrally with a tape part.
    Type: Application

  • Patent number: 4503863
    Abstract: A method and apparatus for monitoring and obtaining actual bio-electrical characteristics of a subject under predetermined conditions of evoked response stimuli, and by interaction with a computer, applying cutaneous electrical stimulation to the subject, using a signal generator to modify current amplitude and frequency in a direction to achieve bio-electrical characteristics in the subject related to the actual bio-electrical characteristics monitored. The signal generator uses a sinusoidal waveform output, with battery power passed through a transformer to power a transconductance amplifier to obtain constant current output despite resistance changes in the line with the subject, and with the transformer not placed in the signal path of the sinusoidal waveform. The signal may be obtained from a sinusoidal oscillator of wide frequency having switched integrator sections connected to an inverting amplifier, pulse generator and gating.

  • Patent number: 4305402
    Abstract: A method and apparatus for monitoring and obtaining actual bio-electrical characteristics of a subject, such as EEG, or determinants of the psycho-electro-physiological state of the subject, under predetermined conditions of evoked response stimuli, and by interaction with a computer, apply cutaneous electrical stimulation to the subject, using a signal generator to modify current amplitude and frequency in a direction to achieve bio-electrical characteristics in the subject related to the actual bio-electrical characteristics monitored. The signal generator may have an output of several frequencies simultaneously, and uses a sinusoidal waveform output, with battery power passed through a transformer to power a transconductance amplifier to obtain constant current output despite resistance changes in the line with the subject, and with the transformer not placed in the signal path of the sinusoidal waveform.
