Abstract: A device is for controlling a temperature-regulating appliance. The device comprises: a sensor arranged to be able to sense effective temperature by the temperature-regulating appliance and to submit a signal as indication of the sensed effective temperature; a control unit arranged to be able to receive the signal from the sensor as an indication for sensed effective temperature and to be able to control the power supply to the temperature-regulating appliance based on the received signal indicating for effective temperature; and one or more energy sources arranged to at least be able to drive the sensor, the control unit and the temperature-regulating appliance. The sensor is constituted by a self-regulating heater cable. A method is for use of a device for control of a temperature-regulating appliance.

Abstract: A device is for regulating a light direction of at least one light source on a movable means of transport. The device comprises a direction indicator arranged to indicate a desired light direction for one or more light sources, and a control unit arranged to read the indicated light direction from the direction indicator and, on the basis of the reading information, adjust one or more light sources to the indicated light direction by one or more drivers connected to the control unit. A method is for regulating the light direction of at least one light source on a movable means of transport. A use of a hand-held wireless pointing device is for regulating the light direction of at least one light source arranged on a movable means of transport.
