Portable and programmable biofeedback system with switching circuit for voice-message recording and playback
First Claim
1. A biofeedback system for recording a message, monitoring a physiological signal and triggering the message upon sensing a predetermined value of the physiological signal, comprising:
- a first component including a sensing means for measuring a physiological signal, said sensing means adapted to be worn in contact with the body of a user and portable; and
a second component includingvoice-message delivery means for delivering a prerecorded voice-message;
voice-message recording means operably linked with said voice-message delivery means for recording said prerecorded voice-message;
processing means operably linked with said sensing means and said voice-message delivery means;
input means manually operable by the user capable of causing a physiological signal threshold value to be set in said processing means;
wherein said processing means includes(a) means to process the physiological signal and to produce a first electronic output conveying the physiological signal measured in real time, (b) means to compare a physiological signal value with said threshold value, (c) means to produce a second output when said physiological signal value equals or exceeds said threshold value, (d) means to terminate said second output when said physiological signal value drops below said threshold value; and
,switch circuitry for receiving said second output and automatically activating and deactivating said voice-message delivery means, wherein said switch circuitry includes a battery operably linked to a switch, said switch having an off mode and an on mode, said switch being operably linked to said voice-message delivery means such that when said switch is in said off mode said battery permits voltage to pass through said voice-message delivery means to allow use of said voice-message delivery means independently from said processing means.

Abstract
A portable and programmable biofeedback system which senses a physiological variable, such as heart rate, and both displays the physiological variable in a visual display in real time and activates and deactivates a user prerecorded voice-message upon reaching a user-programmed threshold value for the physiological variable measured. The system is especially useful in the field of behavior modification which require that the patient have reliable access to his or her behavior modification techniques upon onset of the symptoms associated with a diseased behavior. The invention is made up of a combination of components, namely, a biosignal sensor, a transmitter, a receiver, a processing unit capable of being programmed with a biosignal threshold value and comparing the biosignal to the threshold value, a switching circuit into which an output signal is input, and an analog or digital message recording and playback device operably linked to the switching circuit so that a playback device is activated or deactivated when the output and threshold values match. A display mechanism for visually displaying the real-time changes of the biosignal is linked to the processing unit.
