Abstract

An apparatus includes a first sensor device, a second sensor device and a first processor coupled to the first sensor device and the second sensor device and configured to calculate a probability that the apparatus is in a first state, based on a measurement of the first sensor device, initiate an operation of the second sensor device when the probability exceeds a first value, execute, based on a measurement of the second sensor device, a first detection that detects the apparatus is in a second state, execute, based on the measurement of the first sensor, a second detection that detects the probability exceeds a second value greater than the first value and that the apparatus is in the first state, and based on the first detection and the second detection, output a notification that indicates the apparatus is in both the first state and the second state.

Claims
