Abstract

Embodiments of systems and methods include a sensor subsystem (e.g., within a container-mounted device) that produces a sensor output, and a processing system that implements a state machine. Upon entry into a first state, the processing system starts a timer, and while in a second state, the processing system waits for a specific sensor output value to be received. The processing system transitions from the first state to the second state upon expiration of the timer, and the processing system transitions from the second state to the first state when the sensor output corresponds to the specific sensor output value. When the state machine is in the second state, the output device produces a human-perceptible indicia configured to prompt a human user to perform an action that is likely to cause the sensor to produce the sensor output that corresponds to the specific sensor output value.

a sensor subsystem configured to produce a sensor output indicating a value of a variable sensed condition selected from a motion, an orientation, a change in orientation, an acceleration, shock, a vibration, a magnetic field, a pressure, a temperature, a presence of a chemical, an absence of a chemical, and a humidity level;

a processing system that receives the sensor output and implements a state machine having a first state and a second state, wherein upon entry into the first state, the processing system starts a timer, and while in the second state, the processing system waits for a specific sensor output value to be received, and wherein the processing system transitions from the first state to the second state upon expiration of the timer, and the processing system transitions from the second state to the first state when the sensor output corresponds to the specific sensor output value; and

an output device which, when the state machine is in the second state, produces a human-perceptible indicia configured to prompt a human user to perform an action that is likely to cause the sensor to produce the sensor output that corresponds to the specific sensor output value.
