     * A sensor of this type is defined for devices that are supposed to be worn

     * by the user in the normal use case (such as a watch, wristband, etc) and

     * is not yet defined for other device.

     *

     * A sensor of this type triggers an event each time the wearable device

     * is removed from the body and each time it's put back onto the body.

     * It must be low-latency and be able to detect the on-body to off-body

     * transition within one second (event delivery time included),

     * and 3-second latency to determine the off-body to on-body transition

     * (event delivery time included).

     *

     * There are only two valid event values for the sensor to return :

     *    0.0 for off-body

     *    1.0 for on-body
