/*
|
||
* PULSOMETER face
|
||
*
|
||
* The Pulsometer is an implementation of a sort of a classic mechanical
|
||
* watch complication. A classic pulsometer complication involves a
|
||
* chronograph with a scale calibrated for counting a certain number of
|
||
* heartbeats (often 30). You start it and begin counting heartbeats, and
|
||
* stop it after counting the specified number of beats. Once stopped,
|
||
* the needle will point to your heart rate.
|
||
*
|
||
* The pulsometer on Sensor Watch flashes its instructions at launch:
|
||
* “Hold Alarm + count 30 beats.” Using the hand on the side where you wear
|
||
* your watch, touch your carotid artery (in your neck) and feel for your
|
||
* pulse. Once you find it, use your other hand to press and hold the Alarm
|
||
* button, and count your heartbeats. When you reach 30 beats, release the
|
||
* Alarm button. The display will show a number such as “60 bpm”; this is
|
||
* your heart rate in beats per minute.
|
||
*
|
||
* Two notes:
|
||
* o For the first few seconds of a measurement, the display will read “Hi”.
|
||
* This indicates that it’s too early for the measured value to be a valid
|
||
* heart rate. Once the measurement is below 240 bpm, the display will update.
|
||
* o If you hold the button down for more than 45 seconds, the display will
|
||
* read “Lo”. If it took this long for you to count 30 heartbeats, this
|
||
* indicates that your heart rate is below 40 beats per minute.
