Device for changing the operational state of an apparatus
First Claim
1. A device for changing the operational state of an apparatus, comprising:
- at least one means for transforming a mechanical excitation, applied to the surface of the apparatus, into an electric signal,the at least one means for transforming comprising a passive transducer and a means for amplifying the excitation,the passive transducer disposed between a rigid excitation transmitting means and a support with a central recessed area; and
a power providing means for supplying at least a part of the electric power necessary to enable a change of the operational state of the apparatus from a zero power or power down mode into an active state,wherein the electric power is obtained out of the electric signal.

Abstract
The invention relates to a device for changing the operational state of an apparatus, in particular from a stand-by or power down mode into an active state, which, in order to reduce power consumption during a stand-by mode and, furthermore, in order to reduce accidental powering up of the apparatus, comprises at least one means for transforming a mechanical excitation, in particular applied to the surface of the apparatus, into an electric signal and a power providing means for supplying at least a part of, in particular all, the electric power necessary to enable a change of the operational state of the apparatus wherein the electric power is obtained out of the electric signal. The invention, furthermore, relates to any apparatus comprising this device for changing operational state and a corresponding method.
