Abstract: Broadly speaking, the present techniques provide methods, apparatus and systems for monitoring operation of a device. More particularly, the present techniques provide methods for monitoring operation of a device by observing state transitions which occur during the running of a device process following a firmware update, and either comparing the observed state transitions to a state transition map generated within the device or comparing the observed state transitions to a state transition model in, or associated with, the firmware update.

Abstract: A method for detecting and responding to a configuration setting capable of causing undesired energy consumption in a configurable electronic device comprises measuring a power state of at least one connection point of the configurable electronic device to establish a measured power state value; comparing the measured power state value with a stored power state value for the connection point; and responsive to a discrepancy between the measured power state value and the stored power state value for the connection point where the discrepancy is capable of causing undesired energy consumption, emitting a condition signal.

Abstract: A machine implemented method of authenticating a communication channel between a first device and a second device by providing proof of proximity between both devices, the method comprising: generating, at the first device, an acoustic authentication signal to be received at the second device via a solid body acoustic coupling established between the first device and the second device thereby providing proof of proximity between both devices and so authenticating the communication channel between the first device and the second device.
