Abstract
Abstract An apparatus giving a precise numerical count of the rate of occurrence of a series of discrete events electrically detected such as of a human pulse rate embodying the use of a counter giving a numerical readout of said rate of occurrence for a fixed interval of time directly preceding the count given.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
261 words
An apparatus detecting and recording the rate of occurrence of a series of discrete events, having in combination, means electrically detecting the occurrence of said discrete events, means converting said detected occurrence of said events into logic level signals, counting means, means conducting said signals to said counting means to actuate said counting means to incrementally count up said signals, a recording means, means incrementally writing said signals onto said recording means, means incrementally reading out said signals from said recording means, said writing and said reading means being arranged and positioned with respect to said recording means to provide a desired time space interval therebetween, means conducting said readout signals to said counting means to actuate the same to incrementally count down the numerical value of signals carried by said counting means, a second counting means in parallel relationship to said first mentioned counting means, said first mentioned conducting means conducting said signals to said second counting means to incrementally count up said signals, a second means incrementally reading out said signals from said recording means, said second reading means being arranged and positioned relative with respect to said recording means and in relation to said writing meAns to readout signals from said recording means at a different desired time space interval than the time space interval of reading out by said first mentioned reading means, and means conducting said signal from said second reading means to said second counting means to actuate the same to incrementally countdown from the numerical value of signals carried by said second counting means.
Claim 2
Independent Claim

An apparatus detecting and recording the rate of occurrence of a series of discrete events, having in combination, means electrically detecting the occurrence of said discrete events, means converting said detected occurrence of said events into logic level signals, counting means, means conducting said signals to said counting means to actuate said counting means to incrementally count up said signals, a recording means, means incrementally writing said signals onto said recording means, means incrementally reading out said signals from said recording means, said writing and said reading means being arranged and positioned with respect to said recording means to provide a desired time space interval therebetween, means conducting said readout signals to said counting means to actuate the same to incrementally count down the numerical value of signals carried by said counting means, a second counting means in parallel relationship to said first mentioned counting means, said first mentioned conducting means conducting said signals to said second counting means to incrementally count up said signals, a second means incrementally reading out said signals from said recording means, said second reading means being arranged and positioned relative with respect to said recording means and in relation to said writing meAns to readout signals from said recording means at a different desired time space interval than the time space interval of reading out by said first mentioned reading means, and means conducting said signal from said second reading means to said second counting means to actuate the same to incrementally countdown from the numerical value of signals carried by said second counting means.
Claim 3
Dependent Claim
37 words
The structure set forth in claim 1 including means synchronizing sequentially said signals from said converting means to said first mentioned and second counting means respectively with said signals from said first mentioned and second reading means.
Claim 4
Independent Claim
158 words
An apparatus detecting and recording the rate of occurrence of a series of discrete events, having in combination, means electrically detecting the occurrence of said discrete events, means converting said detected occurrence of said events into logic level signals, counting means, means conducting said signals to said counting means to actuate said counting means to incrementally countup said signals, a recording means, means incrementally writing said signals onto said recording means, means incrementally reading out said signals from said recording means, said writing and said reading means being arranged and positioned with respect to said recording means to provide a desired time space interval therebetween, means conducting said readout signals to said counting means to actuate the same to incrementally countdown the numerical value of signals carried by said counting means, whereby the numerical values of signals carried by said counting means indicates the rate of occurrence of said detected discrete events for said desired time space interval.
Claim 5
Independent Claim
158 words
