1. A method of monitoring a user'"'"'s vital signs, the method comprising:
- deactivating a processor for a deactivation period of 128 to 640 microseconds;
activating an optical sensor during the deactivation period to generate a signal corresponding to the flow of blood through at least one artery of the user, the optical sensor comprising a photodetector and a plurality of light-emitting diodes;
reactivating the processor to process the signal to obtain an average pulse value of a first set of time periods;
processing the 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;
processing the real-time heart rate data of the user for analysis of real-time calories expended by the user and for real-time display of a plurality of the user'"'"'s vital signs; and
displaying the plurality of user'"'"'s vital signs on a display member, the display of the plurality of user'"'"'s vital signs controlled by the user using a control component.

Abstract
A monitoring device (20) for monitoring the vital signs of a user is disclosed herein. The monitoring device (20) is preferably an article (25) having an optical sensor (30) and a circuitry assembly (35). The optical sensor (30) preferably comprises a photodetector (130) and a plurality of light emitting diodes (135). The monitoring device (20) preferably provides for the display of the following information about the user: pulse rate; blood oxygenation levels; calories expended by the user of a pre-set time period; target zones of activity; time; distance traveled; and/or dynamic blood pressure.
