The at least one monitoring unit is connected to the sensor by a wireless communications link of a communications network. The communications network has at least one mobile terminal device on which at least a part of the monitoring unit is provided.

Abstract: A current operational state of a program-controlled domestic appliance is monitored while it carries out an operating process. The monitoring system includes a retrofit module and a communication device separate from the retrofit module and from the domestic appliance. The retrofit module has a fastening arrangement for releasable fastening on an outer face of an appliance housing, a data exchange unit for wireless communication, and a sensor arrangement with a magnetic field sensor that detects a magnetic field that is generated by a drive motor of the domestic appliance and that penetrates outwards through the appliance housing. The system determines the current operational state of the domestic appliance with the aid of detected measured values of the magnetic field and outputs the state via the communication device.

Abstract: A fuel injection device includes a nozzle needle, an actuator for actuating the nozzle needle, a force sensor for detecting a force applied by the actuator, and a control unit which is connected to the force sensor. The force sensor supplies signals to the control unit and the control unit is designed for determining a position of the nozzle needle and for precisely determining an injected fuel quantity, based on the supplied signal.

Abstract: A method creates an operating interface for a first domestic appliance from a plurality of domestic appliances. The method includes providing a plurality of different generic operating elements for specifying different functionalities and/or parameters of the plurality of domestic appliances. The method further includes determining description data for the first domestic appliance. The description data indicate which one or more of the plurality of generic operating elements are used to operate the first domestic appliance and which functionalities and/or parameter values of the first domestic appliance can be set by one or more generic operating elements used. The method also includes creating the operating interface for the first domestic appliance on the input/output unit of a control unit on the basis of the plurality of different generic operating elements and on the basis of the description data for the first domestic appliance.

Abstract: A method for controlling a plurality of domestic appliances with the aid of a portable operating apparatus which wirelessly communicates with the domestic appliances includes transmitting a control signal from the portable operating apparatus to the domestic appliances and using the control signal to jointly change over the domestic appliances between an at-home mode, in which first settings are made in the domestic appliances, and a not-at-home mode, in which second settings are made in the domestic appliances. The portable operating apparatus receives an operator input which is carried out by a user using an input device of the portable operating apparatus, and the control signal for changing over the domestic appliances is emitted by the portable operating apparatus on the basis of the operator input.

Abstract: A system of domestic appliances is provided, wherein the domestic appliances are operated from a branch of an, in particular public, supply system for electrical energy at a customary system frequency, wherein, in particular, the consumed energy which is supplied to the branch can be detected, and wherein a display and measurement unit is present, allowing the energy consumed by an individual domestic appliance to be displayed and measured. In this case, the functioning thereof for determining the consumption of the individual domestic appliance is based on the analysis of a characteristic structure, which can be assigned to the individual domestic appliance, of current and/or voltage profiles within system period time intervals during operation of the individual domestic appliance, wherein, for individual domestic appliances of which the inherent characteristic structure is small, the characteristic structure can be formed or added to by a structure generator.

Abstract: A positioning device includes a positioning element that is situated movably in a first direction and a second direction, the first and the second directions being opposed to one another, and a first piezoelectric actuator and a second piezoelectric actuator, the first piezoelectric actuator moving the positioning element in the first direction and the second piezoelectric actuator moving the positioning element in the second direction.
