Abstract: The invention relates to a system of domestic appliances, 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, this 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, said characteristic structure can be formed or added to by a structure generator (ESM, ES1 to ESN).

Abstract: Spectacles are described having a frame (1), having two spectacle earpieces (5) attached laterally on the frame (1), having two spectacle lenses (2), which engage in receptacle grooves (3) of the frame (1), and having in each case a detachable mounting device for the spectacle lenses (2) in the receptacle grooves (3), which are interrupted in the region of the earpiece attachment (4), wherein the mounting device has, in the region of the interruption (7) of the receptacle groove (3), a sliding bolt (8), which is mounted on the frame outer side and is displaceable transversely to the edge (9) of the spectacle lenses (2). In order to ensure a secure hold of the spectacle lenses (2), it is proposed that the frame (1) have, on the inner side opposite to the sliding bolt (8), a support stop (11) for the spectacle lens (2) having at least one catch attachment (12) engaging in a catch recess of the spectacle lens (2).

Abstract: A method for the phase diagnosis of a multiphase converter for detecting potential errors in individual converter phases is provided, wherein a symmetrical load distribution for the individual converter phases is regulated. During the operation of the converter, the distribution of the load prescribed for each individual phase of the converter is detected at least two different times, at different temperatures, and in any order.

Abstract: Glasses are described having a frame (3) and having nose pads (6) provided in the region of frame attachments (7), which have catch positions arranged in succession in an adjustment direction. To allow an advantageous glasses adaptation, it is proposed that the nose pads (6) be provided on the side opposite to their support surface (10) with a plug-in attachment (9) protruding transversely to the support surface (10), which forms at least two catches (11) in succession in the plug-in direction for alternately engaging in a catch recess (8) of the frame attachments (7).

Abstract: An arm (3) for a pair of glasses made of two sections (6, 7) is described, which are connected to one another via a coiled spring (10), which forms an arm joint (8) and is enveloped using an elastomeric plastic envelope (9). In order to achieve an advantageous bending behavior for the arm joint (8), it is proposed that the plastic envelope (9) have a differing wall thickness around the circumference, which determines the bending resistance of the arm joint (8) with respect to at least one predefined bending axis.

Abstract: A method for patterning a layer stack with at least one ceramic layer includes providing the ceramic layer, which has at least one plated-through hole. An electrically conductive layer is applied above the ceramic layer, such that the electrically conductive layer is electrically coupled to the at least one plated-through hole. A further layer is deposited onto the electrically conductive layer in the region of the at least one plated-through hole, wherein the further layer includes nickel. The electrically conductive layer is removed outside the region of the at least one plated-through hole. A carrier device patterned in this way can be electrically and mechanically coupled to an electronic component.

Abstract: Method for protection of a switching device controlled by a control unit, through which an electric drive can be disengaged during the period of an overvoltage surge caused by a load dump in the electrical system of a vehicle, in which the drive current rises to a maximum value in a first slot within the duration of the overvoltage surge and drops in the second slot connected to the first time slot, with the following process steps: recognition of a load dump by recording a limit voltage value in the electrical system by the control unit, disengagement of the electric drive in the event of a load dump at a switching time stipulated by the control unit, which lies after the first time slot.
