Monitoring Apparatus
Monitoring Apparatus
US Patent:
4860753, Aug 29, 1989
Filed:
Nov 4, 1987
Appl. No.:
7/117211
Inventors:
William A. Amerena - Middleton MA
Assignee:
The Gillette Company - Boston MA
International Classification:
A61B 500
US Classification:
128632
Abstract:
Portable, battery-powered apparatus for monitoring a parameter of human skin includes probe structure with a probe member that has a pair of spaced electrodes for engagement with a skin surface to be monitored. A switch responsive to engagement of the probe member with a skin surface to be monitored provides an output signal. Monitoring circuitry includes pulse generator circuitry coupled to the electrodes and adapted to apply output pulses at a rate that is a function of the capacitance of the skin surface engaged by the electrodes to gate circuitry. Timer circuitry responsive to the output signal of the switch conditions the gate circuitry to pass pulse signals from the pulse generator circuitry to counter circuitry for accumulation. A display of the accumulated count provides an indication of the moisture content of the skin surface contacted by the probe electrodes.
