Abstract: A device (1) comprises a source (20) for emitting ultraviolet light, an inlet (30) for letting in fluid to the device (1), an outlet (40) for letting out fluid from the device (1), and means (51, 52) for performing a straightening action of a flow of fluid through the device (1). The flow straightening means comprise at least one flow straightening element (51, 52) having inlet openings for letting in fluid at one side and outlet openings for letting out fluid at another side, wherein each inlet opening is in communication with a plurality of outlet openings, and wherein the element (51, 52) comprises a maze of randomly arranged, interconnected holes. In such a structure, a water element that is moving from one side of the element (51, 52) to another side may take one of various paths, as a result of which variations in inlet conditions can be dampened.

Abstract: A compact gas discharge lamp (301) comprising four (or more) interconnected tube segments (11, 12, 13, 14) is provided with an external electrode (310) that extends at least throughout the length of the tube segments and that is in contact with all tube segments. Several embodiments of the external electrode are disclosed. The external electrode is preferably connected to a node (C) midway between the lamp electrodes, to which end a capacitive divider (441, 442) is arranged in parallel with the lamp.

Abstract: The invention relates to a wake up stimulus control system, comprising a control unit (1) arranged to receive a user-determinable wake up time input and to control at least one stimulus source (11), a coupling for operably coupling at least one stimulus source (11) to said control unit, wherein the stimulus source (11) is controllable by the control unit (1) in such a way that the stimulus source (11) provides a gradually increasing stimulus output in dependence on said input wake up time, at least during a time period before the input wake up time, and at least one stimulus sensor (7) that is operably coupled to the control unit (1). The sensor allows a much better control of the supplied stimulus level to account for various ambient influences. The stimulus is preferably light. The invention also provides a socket, a stimulus source and a control unit for use in the system.

Abstract: A device comprises a boiler for containing and heating a liquid; and a cool liquid system that is in liquid communication with the boiler, and that is intended to contain relatively cold liquid. During operation of the device, the boiler is activated such as to heat a quantity of liquid that is received from the cool liquid system. In order to avoid heating up of the liquid that is present inside the cool liquid system and cooling down of the liquid that is present inside the boiler, measures are taken in order to prevent a backflow of the liquid. These measures involve an application of some kind of component (9) to be positioned upstream of the boiler, and in order to avoid heat transfer through this component (9), additional measures are taken to realize a heat insulating effect at a position upstream of the boiler.
