Abstract
A device for activating a control unit is proposed. It includes at least one operating element operable by a user as well as analog encoding means assigned to the operating element. To generate an activation signal for a control unit, deactivation means are provided that deactivate at least one analog encoding means in order to digitally encode the operating element.
Claims9
A device for activating a control unit, comprising:
- at least one operating element operable by a user;
- at least one analog encoding arrangement assigned to the at least one operating element in order to detect an operation of the at least one operating element;
- a deactivation arrangement for deactivating the at least one analog encoding arrangement in order to digitally encode the at least one operating element and for generating an activation signal for the control unit, wherein the at least one analog encoding arrangement is deactivated in a rest mode of the control unit.
A device for activating a control unit, comprising:
- at least one operating element operable by a user;
- at least one analog encoding arrangement assigned to the at least one operating element in order to detect an operation of the at least one operating element;
- a deactivation arrangement for deactivating the at least one analog encoding arrangement in order to digitally encode the at least one operating element and for generating an activation signal for the control unit;
- and
- a polarity-reversal arrangement for polarizing at least one diode in a forward direction and for deactivating the at least one analog encoding arrangement.

A device for activating a control unit, comprising:
- at least one operating element operable by a user;
- at least one analog encoding arrangement assigned to the at least one operating element in order to detect an operation of the at least one operating element;
- and
- a deactivation arrangement for deactivating the at least one analog encoding arrangement in order to digitally encode the at least one operating element and for generating an activation signal for the control unit, wherein at least one output signal of the at least one analog encoding arrangement is supplied to a comparator in order to activate the control unit.
