Pulse rate controlled entertainment device
First Claim
1. Apparatus for controlling the on/off state of a portable audio entertainment device carried by a person during the course of an exercise program, in response to achieving a predetermined level of physical activity, comprising:
- (a) means for sensing a physiologic parameter of a human body which changes with level of physical exercise;
(b) signal processing means coupled to said sensing means for producing an electrical control signal when said physiologic parameter being sensed falls above a first threshold value corresponding to a level of exercise beneficial to the body and below a second threshold value greater than said first value where exceeding said second threshold can be injurious; and
(c) circuit means for applying said electrical control signal to said portable entertainment device such that said device plays an audio program only when said physiologic parameter falls between said first threshold value and said second threshold value whereby said person is rewarded by the playing of said portable audio entertainment device so long as said person'"'"'s level of exercise is both safe and effective.

Abstract
A control circuit for a portable radio or like entertainment device which allows it to play only so long as the user'"'"'s heart rate lies within a range commensurate with safe, effective exercise activity. EKG signals are picked up by suitably placed electrodes, amplified, filtered, shaped and applied in one arrangement to a programmable microprocessor and in another arrangement to a linear circuit phase lock loop and window comparator. In each instance, a determination is made as to whether the user'"'"'s heart rate is between a lower limit of effective exercise and an upper limit of safe exercise. When the heart rate is outside the limit, the entertainment device is rendered inoperative, thus providing an incentive to tailor the level of exertion so that the heart rate will lie within the desired range.
