Abstract: The present disclosure concerns a method performed by at least one device, including: acquiring location data indicative of a location of a device which may be placed in a liquid- and/or gas-carrying household appliance; determining treatment chamber data indicative of a conclusion as to whether or not the at least one device is placed in a treatment chamber of the household appliance, the treatment chamber data being determined at least partially based on the acquired location data; and outputting or causing the output of the determined treatment chamber data. Furthermore, the present disclosure concerns a device and a system.

Abstract: The present disclosure concerns a method for operating or controlling an operation of a household appliance (100, 300) performed by at least one device (100, 200, 300, 400). The method includes: obtaining external information representative of at least one external given situation outside the household appliance (100, 300); and operating or controlling an operation of the household appliance (100, 300) at least taking into account the external information obtained. In addition, the present disclosure concerns a device and a system for performing such a method.

Abstract: A device for emanating materials in the environment, preferably by heat evaporation, including: a supply for materials; an emitter of materials, for emitting the materials from the supply to surrounding environment, by application of power from a power supply according to an operation mode; an operation mode adjusting mechanism for adjusting the operation mode of the emitter, by controlling the power delivered to the emitter according to a determined transfer function. The transfer function is modular, so that it can be changed or completely replaced while keeping at least partially the adjusting mechanism in the device.

Abstract: A panel for an electronic device, with a front side, and a back side. The panel including a sign, suitable to be viewed from the panel's front side, wherein the sign has an annular shape. The sign has 3 indicia mit light, each being an annular segment of the annular shape, each with an angular length, and further each two adjacent indicia mechanisms are spaced by an angular gap alpha, and wherein 0°<=alpha is <=20°.
