 /**
- * Wrapper around SensorManager customized for the Proximity sensor.
- *
- * The ProximitySensor supports the concept of a primary and a
- * secondary hardware sensor. The primary sensor is used for a first
- * pass check if the phone covered. When triggered, it then checks
- * the secondary sensor for confirmation (if there is one). It does
- * not send a proximity event until the secondary sensor confirms (or
- * rejects) the reading. The secondary sensor is, in fact, the source
- * of truth.
- *
- * This is necessary as sometimes keeping the secondary sensor on for
- * extends periods is undesirable. It may, however, result in increased
- * latency for proximity readings.
- *
- * Phones should configure this via a config.xml overlay. If no
- * proximity sensor is set (primary or secondary) we fall back to the
- * default Sensor.TYPE_PROXIMITY. If proximity_sensor_type is set in
- * config.xml, that will be used as the primary sensor. If
- * proximity_sensor_secondary_type is set, that will function as the
- * secondary sensor. If no secondary is set, only the primary will be
- * used.
+ * Wrapper class for a dual ProximitySensor which supports a secondary sensor gated upon the
+ * primary).

+/**
+ * Wrapper around SensorManager customized for the Proximity sensor.
+ *
+ * The ProximitySensor supports the concept of a primary and a
+ * secondary hardware sensor. The primary sensor is used for a first
+ * pass check if the phone covered. When triggered, it then checks
+ * the secondary sensor for confirmation (if there is one). It does
+ * not send a proximity event until the secondary sensor confirms (or
+ * rejects) the reading. The secondary sensor is, in fact, the source
+ * of truth.
+ *
+ * This is necessary as sometimes keeping the secondary sensor on for
+ * extends periods is undesirable. It may, however, result in increased
+ * latency for proximity readings.
+ *
+ * Phones should configure this via a config.xml overlay. If no
+ * proximity sensor is set (primary or secondary) we fall back to the
+ * default Sensor.TYPE_PROXIMITY. If proximity_sensor_type is set in
+ * config.xml, that will be used as the primary sensor. If
+ * proximity_sensor_secondary_type is set, that will function as the
+ * secondary sensor. If no secondary is set, only the primary will be
+ * used.
