D 683  such as a red  LED  blinks at the rate ofthe pulse  the LED 683 serves as an  output indicator  Instead of a LED output  in an alternative  embodiment  the glasses can use audio instead of or in addi   tion to visual clues  In such cases  the glasses may support a  speaker orothertypes of output mechanisms  such as LCD  as  discussed in this or related patent applications incorporated  by reference    In another embodiment  the signals S1 could be sent to the  input of an analog to digital converter  whose outputs are  received by a digital signal processor to digitally process the  signals    Typically  when worn  a pair of glasses is in a stable posi   tion relative to the user s head and ears  The stability serves as  a good platform for a heart rate sensor  Though the glasses  serve as a stable platform  there can still be noise  With the  clip applied to the user  if the user moves  the wire 514 could  move with her  which  in turn  could move the clip 510 rela   tiveto the user  The heart rate signals from the sensor could be  small relative to  for example  noise signals or the DC offset   As an illustration  a clip that moves during measurement  could change the DC offset because the amount of tissue  compressed or measured by the clip could change  This  change in DC offset could produce noise  reducing the signal   to noise ratio    There are different techniques to enhance clip stability  when clipped to the user  One can increase the pressure ofthe  clip  H

22. S     which is hereby incorporated herein by refer   ence     BACKGROUND OF THE INVENTION    There are various devices to measure heart rates  For  example  one approach depends on wrapping a band across a  person s chest  Electrodes in the band can sense the person s  heart beat and wirelessly transmit the measured signals to a  receiver  This approach can be quite inconvenient because the  person has to wear a band across his chest in order to get the  necessary measurements    Another approach to measure heart beat is to clip an infra   red sensor onto a person s finger  The sensor is connected to  a machine through a wire  This approach 1s unsatisfactory if  one intends to remain active  or to use one s hands while  measurements are taken    It should be apparent from the foregoing that there is still a  need for an accurate heart rate monitor that is convenient to  use for a person who may be in motion     SUMMARY OF THE INVENTION    In one embodiment  the present invention provides a heart  rate sensor attached to  integral with or tethered to a pair of  glasses  When worn  the pair of glasses is in a stable position  relative to the user  The glasses serve as a good platform for  heart rate sensing     US 7 677 723 B2    8    In one embodiment  the sensor can be an infrared transmit   ter with an infrared detector on a clip  The clip could be  tethered to a temple ofthe glasses  The user can attach the clip  to her ear lobe to measure her heart rate  With the ear lobe
