Electrical devices
First Claim
1. A portable communications device comprising a first body portion and a second body portion, wherein:
- the first body portion has a transceiver operable to enable transmission and reception of communications over a mobile telecommunications network, a controller operable to control operation of the device, and a signal supplier operable to supply a carrier signal;
the first body portion and the second body portion have respective first and second wireless couplers arranged in close proximity to one another to enable wireless coupling of the carrier signal from the first wireless coupler to the second wireless coupler;
the second body portion carries a data storage device having a memory storing data, a power supply deriver operable to derive a power supply from a carrier signal coupled to the second wireless coupler, a controller operable to read data from the memory in response to derivation of a power supply by the power supply deriver, and a modulator operable to modulate the carrier signal in accordance with data read from the memory;
the first body portion has a data extractor operable to extract data from the modulation of the carrier signal and a data supplier operable to supply the data to the controller of the first body portion to affect a function relating to the operation of the portable communications device.

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.
