Abstract: In some examples, a controller receives, from a sensor that is part of a device mounted on a moveable platform, measurement data. The controller detects, based on the measurement data, a change in transit motion status of the moveable platform. The controller triggers, in response to detecting the change in transit motion status of the moveable platform, a transition of the device from a first power state to a second, different power state.

Abstract: Based on a relationship between measurement data from at least one sensor and a baseline, a load status of a platform is determined. In response to the determined load status, such as determining that the platform is empty, the baseline is refined using a baseline estimator to produce a refined baseline that can be used to determine a further load status of the platform.
