Abstract: A skin radiation apparatus comprises: —a photon radiation unit (10) for generating a line-shaped radiation pattern (12) extending in a first direction (x), the photon radiation unit comprising a photon radiation source (14), —a movement facility (20, 22) for moving the line shaped radiation pattern in a second direction (y) transverse to the first direction (x), —a detection unit (30) for detecting a skin condition profile, —a control unit (40) for controlling an power density distribution for the line-shaped radiation pattern dependent on the skin condition profile detected by the detection unit (30).

Abstract: A self-heating container (1, 2) to prepare a fresh hot beverage containing a compartment containing a heat-delivering substance (8) to heat the liquid in the device, an airtight compartment (11) containing a measured amount of liquid to be heated, an airtight compartment containing a measured amount of dry matter for preparing a hot beverage, a filter (11) for separating the dry matter from the liquid (optional) and a compartment containing a measured amount of liquid to actuate the heat-delivering substance (8) with the attribute that the heat-delivering substance is actuated (13) simultaneously with the release of the dry matter to the compartment containing the measured amount of liquid to be heated during actuation.
