Abstract
In some examples, a sensor device is to mount to a barrier pivotable between an open position and a closed position, the barrier being on a moveable platform. The sensor device includes an accelerometer to measure acceleration data and a rotation sensor to measure rotation about an axis. The sensor device includes at least one processor configured to determine an open/close status of the barrier based on the acceleration data and the rotation data, and an orientation of the moveable platform.
Claims21
An apparatus comprising:
- a sensor device to mount to a barrier pivotable between an open position and a closed position, the barrier mounted on a moveable platform, the sensor device comprising a rotation sensor to measure rotation about an axis;
- and
- at least one processor configured to:
- determine an open/close status of the barrier based on rotation data from the rotation sensor and an orientation of the moveable platform.
A method of at least one processor, comprising:
- receiving, from a rotation sensor, rotation data at a plurality of time points, the rotation sensor being part of a sensor device mounted to a barrier that is pivotable between an open position and a closed position, the barrier pivotably mounted to a frame on a moveable platform;
- aggregating the rotation data at the plurality of time points to produce an aggregate value;
- and
- determining, based on the aggregate value, whether the barrier has moved to the open position or the closed position, wherein the determining of whether the barrier has moved to the closed position is further based on an orientation of the frame that is variable due to movement of the moveable platform.
A non-transitory machine-readable storage medium storing instructions that upon execution cause at least one processor to:
- receive rotation data from a rotation sensor;
- receive acceleration data from an accelerometer;
- determine that a barrier mounted on a moveable platform is in an open position based on the rotation data indicating that the barrier has rotated by greater than a first threshold;
- and
- determine that the barrier is in a closed position based on the rotation data indicating that the barrier has rotated by less than a second threshold and the acceleration data converging to a specified value that is based on an orientation of the moveable platform.
