A utilitarian device is disclosed comprising a body 2 in which are incorporated electronic circuitry and a power storage component 10 therefor. The circuitry includes an electronic memory 24, and provision is made for adding information to that memory 24 as the device is used. An induction generator 12 can also be incorporated in the body 2 to sustain the power storage component 10. Information can be added to the memory 10 at any stage from manufacture of the device to and during its ultimate use, thereby creating an effective history of the device in the memory 24. A particular embodiment of the invention is an inhaler in which the ultimate user can keep an effective record of activity. |
