Abstract: The present invention relates to a method for examining a beam of charged particles, including the following steps: producing persistent interactions of the beam with a sample at a plurality of positions of the sample relative to the beam and deriving at least one property of the beam by analyzing the spatial distribution of the persistent interactions at the plurality of positions.

Abstract: In a method for monitoring a cooking process, a movement of an object in an area of a cooktop is detected. The detected movement is evaluated for a predetermined time. An indicator of a development of smoke in the area of the cooktop is detected and evaluated, and a warning signal is being output when a movement for the predetermined time is absent and the indicator is present.

Abstract: In a method for monitoring a cooking process, a cooking receptacle is detected on a cooking zone of a cooktop. The detected cooking receptacle is determined by determining a surface of a food to be cooked which is contained in the cooking receptacle. A change in level of the surface of the food is determined over a predetermined time, and a rising rate of the food is ascertained as a result of the change in level. Based on the ascertained rising rate, a probability of a boiling over of the food is predicted and a warning signal is output based on the predicted probability of the food boiling over.

Abstract: In a method for optical ascertainment of an operating state of a cooktop, objects are optically detected within a detection space including the cooktop with at least two cooking zones and a control panel with at least two identifiers. The cooking zones and the identifiers are recognized based on optically detected properties of the objects. A centroid for each object is determined and the cooking zones and the identifiers are arranged based on detected coordinates of the respective centroids in the detection space. The identifiers are assigned to a respective cooking zone based on the arrangement of the cooking zones and the identifiers, and an operating state for at least one cooking zone is ascertained based on a detected unambiguous feature of one of the identifiers assigned to the at least one of the cooking zones.

Abstract: A filter unit for an air cleaning device includes an odor filter configured for odor neutralization and embodied as a device for plasma generation. The odor filter includes an air-permeable high-voltage electrode and an air-permeable counter electrode arranged behind one another in a direction of flow of air. Each of the air-permeable high-voltage electrode and the air-permeable counter electrode is formed by a panel element.

Abstract: An electrostatic filter unit for an air cleaning device includes an ionization unit configured to ionize particles in air and to deplete odor, and a separation unit arranged downstream of the ionization unit in a direction of flow of air and configured to separate particles.

Abstract: An electrostatic filter unit for an air cleaning device includes an ionization unit for charging a particle contained in an air flow, a separation unit arranged downstream of the ionization unit in a direction of flow of the air, with the separation unit including at least two collecting electrodes which are air-permeable, and a protection element for at least one element of the ionization unit.

Abstract: A filter unit for an extractor hood includes a housing and an electric contact element arranged on a wall of the housing such as to be accessible from outside. Accommodated in the housing are an ionization unit and a separation unit which is mounted in the housing downstream of the ionization unit in a direction of flow.

Abstract: An electrostatic filter unit for an air-purification device, the filter unit comprising an ionization unit and a separation unit with at least one voltage-carrying collecting electrode and at least one grounded collecting electrode, characterized in that the at least two collecting electrodes are air-permeable.

Abstract: An electrostatic filter module for an air cleaner includes a housing having an installation space configured to be sealed at least against ingress of liquid. The installation space has a high-voltage connection and a connection for lower voltage. Arranged in the housing are a separation unit and an ionization unit arranged in the housing, and a high-voltage transformer is accommodated in the installation space of the housing.

Abstract: In a method for controlling at least one function of a household appliance, a control device senses contactlessly the presence of a user's hand in a sensing space. A characteristic of the sensed hand is detected by the control device, and a function of the household appliance is actuated using the detected characteristic.

Abstract: A cooking appliance includes a cooking chamber having a loading opening which is closable by a door. A light pattern projector is arranged in a fixed manner relative to the cooking chamber and configured to generate and radiate a light pattern into the cooking chamber. A camera captures images from a region being irradiated by the light pattern projector when the cooking chamber is closed, and is arranged in a fixed manner relative to the cooking chamber, Coupled to the camera is an analysis facility which repeatedly calculates a three-dimensional shape by light pattern analysis of an object located in the region being irradiated by the light pattern projector during operation of the cooking appliance.
