Abstract
A data indicator is disclosed which comprises a non-volatile memory (26), control circuitry (24) by which data can be read from and written to the memory, a timer (28) and/or an event detector (30), means such as a terminal (20) for connection to an electrical supply of a host apparatus and an interface (32) through which data can be exchanged with the memory (26). In use, the event detector (30) detects when the host apparatus is switched on and in dependence on the detector output the control circuitry (24) maintains a cumulative history of host apparatus activation which is stored on the memory (26). The data indicator can store other data relating to the host apparatus, e.g. a service interval, and can supply this in conjunction with the actuation history, making it conveniently possible e.g. to establish whether the host apparatus requires servicing. (FIG. 4).
