First Claim
1. An electrical medical device comprising a main body and an accessory;
- the main body having a main body controller operable to control operation of the medical device and a signal supplier operable to supply a carrier signal;
the main body and the accessory having respective first and second couplers arranged in close proximity to one another when the accessory is in the proximity of or attached to the main body to enable coupling of the carrier signal from the first coupler to the second coupler;
the accessory carrying a data storage device having a memory storing technological feature data for the accessory, a power supply deriver operable to derive a power supply from a carrier signal coupled to the second coupler, a data storage device controller operable to read data from the memory in response to derivation of a power supply by the power deriver, and a modulator operable to modulate the carrier signal in accordance with technological feature data read from the memory, the main body having a data extractor operable to extract the technological feature data from the modulation of the carrier signal and a data supplier operable to supply the data to the main body controller to affect the operation of the medical device in accordance with the technological feature data for the accessory.

Abstract
An electrical device such as a portable communications device, domestic or personal care appliance has a main body adapted to couple to an accessory which may be in the form of a tool attachable to the main body or a housing portion. The accessory carries a passive data storage device having a memory (59) storing control data for controlling an operation or affecting a function of the device. The passive data storage device is arranged to derive a power supply from the main body when a first coupler carried by the main body is placed in proximity to a second coupler carried by the accessory (3). Where the electrical device is a portable communications device, then the accessory may be, for example, a fascia. The coupling between the first and second couplers may be inductive or capacitive.
