Apparatus For Maintaining Signals Within A Given Amplitude Range

US Patent:
4153049, May 8, 1979
Filed:
Nov 16, 1977
Appl. No.:
5/852170
Inventors:
Ronald D. Gatzke - Lexington MA
James L. Larsen - Bedford MA
Elliott S. Simons - Framingham MA
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
D61B 504
US Classification:
128419D
Abstract:
Displayed ECG waveforms are maintained within acceptable aspect ratios without rapid fluctuation in amplitude by rapidly decreasing the gain of the signal channel by discrete amounts as the peak-to-peak amplitude of the ECG signal increases through each of a number of levels and by increasing the gain of the signal channel only after the peak-to-peak amplitude of the ECG signals has dropped to a given fraction for a predetermined period of time.
