1. A smoke detector of a movable vessel comprising:
- a status light emitting diode (LED);
at least one accelerometer configured to;
sense movement of the movable vessel; and
provide a sensor signal representative of the sensed movement; and
one or more processors configured to;
receive the sensor signal;
determine whether the sense movement exceeds a threshold based upon the sensor signal; and
adjust a blinking rate of the status LED based upon the sensor signal such that the blinking rate of the status LED is set to a first blinking rate if the sensed movement is equal to or less than the threshold and the blinking rate of the status LED is set to a second blinking rate if the sensed movement exceeds the threshold.

Abstract
A smoke detector of an aircraft cargo container includes a status light emitting diode (LED), at least one accelerometer, and one or more processors. The at least one accelerometer is configured to sense movement of the aircraft cargo container and provide a sensor signal representative of the sensed movement. The one or more processors is configured to receive the sensor signal and adjust a blinking rate of the status LED based upon the sensor signal.

10. A method comprising:
-
sensing movement of a movable vessel using at least one accelerometer of a smoke detector; providing a sensor signal representative of the sensed movement using the at least one accelerometer of the smoke detector; receiving the sensor signal using one or more processors of the smoke detector; determining, using the one or more processor, whether the sensed movement exceeds a threshold based upon the sensor signal; and adjusting a blinking rate of a status LED of the smoke detector based upon the sensor signal using the one or more processors by setting the blinking rate of the status LED to a first blinking rate if the sensed movement is equal to or less than the threshold and to a second blinking rate if the sensed movement exceeds the threshold. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
