EXERCISE CONTROL SYSTEM
First Claim
1. An exercise control system adapted for use with means for a person to exercise on, comprising, means for detecting his actual pulse, means for converting the detected pulse rate to a first electrical signal proportional to said detected pulse rate, means for setting and producing a reference electrical signal proportional to a single desired pulse rate, and means for comparing said first electrical signal to said reference signal and for indicating deviation on either the low side or the high side of said desired pulse rate, said comparing and indicating means having no connection to said exercising means.

Abstract
An exercise measuring system in which a person'"'"''"'"'s pulse rate while exercising is electronically detected and compared against a desired level. Pickup electrodes are strapped to the person'"'"''"'"'s chest to pick up his pulse rate while he is exercising and this pulse rate is then fed to an electronic indicating device which compares it with a preset rate, or level. Deviations above or below this level are indicated by respective lights. Lights are also provided to respectively indicate when the user'"'"''"'"'s pulse rate is maintained at the preset level and when the pulse rate has been maintained at the preset level for a predetermined length of time.

-
4. The exercise control system as defined in claim 2 in further combination with timing means operatively connected to said comparing and indicating means for actuation thereby when said d.c. voltage matches said reference voltage, including means for indicating the termination of a preselected time period during which said d.c. voltage matches said reference voltage.
-
5. An exercise control system of the character described including, an electronic transducer to detect a person'"'"''"'"'s pulse rate while exercising and to provide a signal proportional to the pulse rate, said transducer comprising electrode means to sense a person'"'"''"'"'s heart beat, wave forming means to convert the pulse so detected into a repetitive wave whose repetition rate is determined by the frequency of said pulses, and means to convert said repetitive wave into a variable d.c. voltage signal the level of which is proportional to said repetition rate, said system further including comparing means, operatively connected to said means to convert, for comparing said variable d.c. voltage with a predetermined voltage value, and three switch means including '"'"''"'"''"'"''"'"'desired,'"'"''"'"''"'"''"'"' '"'"''"'"''"'"''"'"'high,'"'"''"'"''"'"''"'"' and '"'"''"'"''"'"''"'"'low'"'"''"'"''"'"''"'"' circuits which respectively control '"'"''"'"''"'"''"'"'desired,'"'"''"'"''"'"''"'"' '"'"''"'"''"'"''"'"'high,'"'"''"'"''"'"''"'"' and '"'"''"'"''"'"''"'"'low'"'"''"'"''"'"''"'"' indicators, said switch means being operatively connected to said comparing means for selective actuation in response to said comparing means in accordance with whether a said voltage signal is above, below or equal to said predetermined voltage value.
