Abstract
A method at a sensor apparatus, the method including calculating a value for a target function based on at least one sensor of the sensor apparatus; determining that the value of the target function is within a defined threshold range for a defined time period, thereby finding an in-flight state for the sensor apparatus; and turning off transmission from a radio of the sensor apparatus based on the in-flight state.
Claims19
A method at a sensor apparatus, the method comprising:
- calculating a value for a target function at the sensor apparatus, the target function being a weighted summation of a moving variance of three accelerometers at the sensor apparatus, the moving variance from each accelerometer being provided with an independent weighting value;
- determining that the value of the target function is greater than a first threshold at a first moment;
- finding that the value of the target function is greater than a second threshold for a first defined time period after the first moment, the second threshold being less than the first threshold;
- based on the determining and finding, declaring an inflight state for the sensor apparatus;
- and
- turning off transmission from a radio of the sensor apparatus based on the inflight state.
A sensor apparatus comprising:
- a processor;
- and
- a communications subsystem,
- wherein the sensor apparatus is configured to:
- calculate a value for a target function at the sensor apparatus, the target function being a weighted summation of a moving variance of three accelerometers at the sensor apparatus, the moving variance from each accelerometer being provided with an independent weighting value;
- determine that the value of the target function is greater than a first threshold at a first moment;
- find that the value of the target function is greater than a second threshold for a first defined time period after the first moment, the second threshold being less than the first threshold;
- declare an inflight state for the sensor apparatus;
- and
- turn off transmission from a radio of the sensor apparatus based on the inflight state.
A non-transitory computer readable medium for storing instruction code, which, when executed by a processor on a sensor apparatus cause the sensor apparatus to:
- calculate a value for a target function at the sensor apparatus, the target function being a weighted summation of a moving variance of three accelerometers at the sensor apparatus, the moving variance from each accelerometer being provided with an independent weighting value;
- determine that the value of the target function is greater than a first threshold at a first moment;
- find that the value of the target function is greater than a second threshold for a first defined time period after the first moment, the second threshold being less than the first threshold;
- declare an inflight state for the sensor apparatus;
- and
- turn off transmission from a radio of the sensor apparatus based on the inflight state.
