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 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. The article (25) is preferably a band worn on a user's wrist, arm or ankle.
Claims5
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;
- 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.
