摘要:
The radiation-selective absorber coating (20) has two barrier layers (24a, 24b), an IR-reflecting layer (21) arranged thereon, an absorption layer (22) arranged above the IR-reflecting (21) and an antireflection layer (23) over the absorption layer (22). The absorber tube (13) is a steel tube (1) with the radiation-selective absorber coating (20) applied to the outside thereof. In the process of coating the absorber tube (13) a first oxide barrier layer (24a) is applied to a steel tube by thermal oxidation; a second barrier layer (24b) is then applied by physical gas phase deposition of silicon with supply of oxygen; the IR-reflecting layer (21) is then applied by gas phase deposition of gold, silver, platinum or copper; the absorption layer (22) is then applied by deposition of aluminium and molybdenum; and a final antireflection layer (23) is applied by deposition of silicon with supply of oxygen.

The present invention relates to a glazing element for facing building facades or window systems, in particular for motor vehicles, trains or aircraft, having at least two panes, which enclose an intermediate space, and on one pane surface facing said intermediate space a coating buildup is provided, having an electrically conductive layer applied to one pane surface, thereupon an electrochromic, and thereupon an ion-conducting and thereupon an electrocatalytic layer. The invention is distinguished by the fact that, in addition to the coating buildup in the intermediate space, which is free of water, solely a reducing or oxidizing gas or gas mixture comprising a reducing or an oxidizing gas or a gas mixture comprising a reducing or an oxidizing gas and an inert gas is provided and that an electric voltage of less than 1.2 volts between the electrically conductive and the electrocatalytic layer is applied.
摘要:
In a system for communicating optically encoded data among a network of nodes, the nodes are connected to each other by optical transmit and receive fibers. Each node includes a laser, a transmitter, and a receiver connected to the transmitters of the other nodes by a fiber stretcher. The rate at which the laser generates light pulses is controlled by a frequency control signal supplied to an oscillator connected to the laser. The delay from the transmitters to the receivers is controlled by a phase control signal supplied to the fiber stretcher connected to the receive fiber. The transmitter connected to the transmit fiber selective delays the pulses into a plurality of time multiplexed channels. The receiver connected to the fiber stretcher selectively detects the pulses in the time multiplexed channels while all of the pulses of all of the nodes are globally synchronized in all of the time multiplexed channels in frequency and phase using the frequency and phase control signals.

A glazing element, in particular, for facing building facades, having two nes enclosing a gaseous atmospheric intermediate space and having a predetermined layer on at least one pane surface facing the intermediate space. The glazing element is distinguished by the fact that the predetermined layer has a reactive layer applied on one pane and a catalytic layer applied on the reactive layer. The catalytic layer, depending on the composition of the gas atmosphere contained between the panes, activates in the reactive layer. The reaction changes the optical and/or electrical properties of the reactive layer, and varies the composition of the gas atmosphere in the intermediate space, thereby making the electrical and/or optical properties of the reactive layer variable.

摘要:
Described is an optical element having a region arranged on a first substrate and comprising at least one layer, the region containing a reactive material, a dye, and ion storage, whereby a redox system and at least one ion are present in the ion storage. The dye is hereby in contact with the reactive material, either directly or by means of a conductive layer, such that an optically induced charge transfer flow (forward reaction) can be achieved from the dye to the reactive material, either directly or by means of the conductive layer within the region that comprises at least one layer. A charge carrier return flow (reverse reaction) can occur via the same interface as the forward reaction, or alternatively, via external wiring and a second electrode. The external wiring can contain a switch.
