Abstract: A photoacoustic detector unit comprises a housing having an opening, and also a photoacoustic transducer designed to convert optical radiation into at least one from a pressure signal or a heat signal. The photoacoustic transducer covers the opening of the housing, such that the photoacoustic transducer and the housing form an acoustically tight cavity. A pressure pick-up is arranged in the acoustically tight cavity.

Abstract: A cabinet-shaped piece of furniture having a folding lid (2) with two lid parts (3, 4) which are arranged one above the other. The upper lid part (3) is pivotally hinged to the body (1) of the piece of furniture, and the lower lid part (4) is pivotally [hinged] to the upper lid part (3). The axis of rotation (13) between the two lid parts (3, 4) lies in the region of the wall thickness (5) of the lid parts (3, 4). The distance of the instantaneous centre of rotation (20) of the lower lid part (4) from the lower edge (16) of the lower lid (4), when the folding lid (2) is closed, amounts to 25% of the height (h) of the lower lid part (4).
