+     * 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
