+ * 35 degrees since the activation of the sensor.
+ *     initial_estimated_gravity = average of accelerometer measurements over the first

+ *     trigger when angle (initial_estimated_gravity, current_estimated_gravity) > 35 degrees
+ *
+ * Large accelerations without a change in phone orientation should not trigger a tilt event.
+ * For example, a sharp turn or strong acceleration while driving a car should not trigger a tilt
+ * event, even though the angle of the average acceleration might vary by more than 35 degrees.
+ *
+ * Typically, this sensor is implemented with the help of only an accelerometer. Other sensors can
+ * be used as well if they do not increase the power consumption significantly. This is a low power
+ * sensor that should allow the AP to go into suspend mode. Do not emulate this sensor in the HAL.
+ * Like other wake up sensors, the driver is expected to a hold a wake_lock with a timeout of 200 ms
+ * while reporting this event. The only allowed return value is 1.0.
