Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
57 words
Two channel means for applying electrical impulses to a body through electrodes comprising: a. a first circuit including a first electrode and a common electrode; b. a second circuit including a second electrode and said common electrode; and manual means in each circuit for independently controlling the frequency of pulses delivered to the first and second electrodes.
Claim 2
Dependent Claim
57 words
Two channel means for applying electrical impulses to a body through electrodes comprising: a. a first circuit including a first electrode and a common electrode; b. a second circuit including a second electrode and said common electrode; and manual means in each circuit for independently controlling the frequency of pulses delivered to the first and second electrodes.
Claim 3
Dependent Claim
20 words
Means as in claim 1 which further includes means in each circuit for independently controlling the width of the pulses.
Claim 4
Dependent Claim
15 words
Means as in claim 1 which includes means for controlling the amplitude of the pulses.
Claim 5
Independent Claim
71 words
The method of controlling human pain and discomfort including but not limited to that arising from withdrawal of a habituated chemical or activity comprising the steps of: a. applying high voltage pulses to a body member between a first location and a common location at a first frequency and simultaneously b. applying high voltage pulses to the body member between a second location and said common location at a second frequency.
Claim 6
Independent Claim
71 words
The method of controlling human pain and discomfort including but not limited to that arising from withdrawal of a habituated chemical or activity comprising the steps of: a. applying high voltage pulses to a body member between a first location and a common location at a first frequency and simultaneously b. applying high voltage pulses to the body member between a second location and said common location at a second frequency.
