Abstract: The invention relates to a weighing device, e.g. for kitchens. It has a support plate (1) for receiving the object to be measured and a controller (16). Furthermore, an excitation element (12) for generating mechanical vibrations in the support plate (1) and a measuring element (14) for measuring the mechanical vibrations of the support plate (1) are provided. The excitation element (12) and the measuring element (14) are used to determine one or more resonance frequencies and/or other spectral characteristics of the support plate (1), and this is used, for example, to determine the mass of the object.

Abstract: The invention relates to a vacuum processing system for processing a substrate (2), with an enclosure (1) for carrying the substrate (2) to be treated in a substrate plane (4), whereby the enclosure (1) comprises a first reflecting means (6) and a heating means (5) having a first plane surface (10) and an opposed second plane surface (11), the heating means (5) is configured for irradiating heating energy only via the first surface (10) and/or via the second surface (11), the first reflecting means (6) is configured for reflecting the heating energy irradiated by the heating means (5) onto the substrate plane (4), and the heating means (5) is arranged such that the first surface (10) faces towards the first reflecting means (6) and the second surface (11) faces towards the substrate plane (4).
