Abstract

A method and system to monitor a prisoner in a prison is disclosed herein. The prisoner'"'"'s vital signs are monitored and the movement of the prisoner. The monitoring device measures real-time data for the at least one vital sign of the prisoner, calculates at least a real-time heart rate data, and transmits the real-time heart rate data to the receiving device for display on the display screen.

Claims

1. A method for monitoring a plurality of real-time vital signs of a prisoner, the method comprising:

generating a digital signal corresponding to the flow of blood through an artery of the prisoner, the digital signal generated from an optical sensor in proximity to the artery of the user and integrated into clothing of the user;

filtering motion noise from the digital signal utilizing a motion sensor;

processing the digital signal to obtain an average pulse value of a first set of time periods;

processing the digital signal to obtain an average pulse value of a second set of time periods, the second set of time periods less than the first set of time periods;

subtracting the average pulse value of the second set of time periods from the average pulse value of the first set of time periods to generate a first filtered pulse data value;

processing the first filtered pulse data value to obtain a first heart rate value;

using the first heart rate value to filter the subsequent average pulse values generated from the digital signal to obtain a real-time heart rate value of the user;

transmitting the real-time heart rate data of the user to a base station;

transmitting the real-time heart rate of the user from the base station to a receiving device; and

displaying the real-time heart rate data of the user on a display screen of the receiving device.

2. The method according to claim 1 wherein the optical sensor comprises a pulsed infrared LED and a photodetector.

3. The method according to claim 1 wherein the optical sensor comprises a pulsed infrared LED, a green light LED and a photodetector.

4. The method according to claim 1 wherein a short range wireless transceiver of the monitoring device operates on a communication protocol using BLUETOOTH, PART 15, WiFi, Infrared, and ultrasound.

5. The method according to claim 1 wherein the receiving device is an access point.
