Abstract
An apparatus including an electrical energy storage device arranged to provide an output voltage that decreases with time;a reference clock; and a multi-mode controller having a first mode in which the reference clock is disabled and a second mode in which the reference clock is enabled, the multi-mode controller being operable, when in the first mode, to monitor a voltage provided by the electrical energy storage device and to change the mode of the controller from the first mode to the second mode when the monitored voltage falls beneath a threshold value and being operable, when in the second mode, to enable storage of electrical energy in the electrical energy storage device.
