Abstract:
1. A system for monitoring a user's heart rate, the system comprising: a smartphone comprising a short range wireless transceiver, a processor and a display screen; a heart rate monitoring device integrated into a bra of the user, wherein the heart rate monitoring device comprises: an optical sensor, an accelerometer, a processor, a powering source for the monitoring device; and a short range wireless transceiver for transmitting the real-time vital sign signal; wherein the processor is configured to filter motion noise from a digital signal from the optical sensor utilizing a signal from the accelerometer, process the digital signal to obtain an average pulse value of a first set of time periods, process 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, subtract 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, process the first filtered pulse data value to obtain a first heart rate value, and use 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.
