In at least one embodiment, an ambient lighting system comprising a lighting module and a controller is provided. The lighting module is configured to drive a light emitting device (LED) arrangement to display a desired ambient color in response to a lighting control signal and to transmit a lighting status signal providing diagnostic information for one of the lighting module and the LED arrangement. The controller is configured to transmit the lighting control signal including first digital data indicative of the desired ambient color and a feed signal for powering the lighting module on a bi-directional data communication bus between the controller and the lighting module. The controller is further configured to receive the lighting status signal on the bi-directional data communication bus.
摘要:
The invention relates to a process for coating metal surfaces with an aqueous composition in the form of a solution or in the form of a dispersion, the composition comprising at least one phosphate, at least 3 g/l of at least one titanium or/and zirconium compound and at least one complexing agent, and also to corresponding aqueous compositions. The coatings prepared thereby have very good bare corrosion protection in the NSS salt spray test and in the condensation-water/constant-climate test

A balun, generally including a substrate, a microstrip conductor, and a parallel strip conductor is described, where a characteristic impedance of the balun is substantially constant at each cross-sectional point along a length of the balun. A transverse electromagnetic horn antenna can transmit and receive ultra-wide band pulses, and includes a first metal conductor and a second metal conductor, where a characteristic impedance of the first and second conductor varies over a length of the antenna in a controlled means.

A relatively dry, oxygen-poor, heated fluid is provided for conveying wood fibers through the drying cycle subsequent to crushing the wood chips and for also conveying and distributing the wood fibers from the drying cycle onto a mat-forming wire. The primary source of the fluid is the combustion gases from a burner. Secondary fluids including ambient air, recirculated gases from the drying cycle and inert gases may be introduced to cool the fluid to the desired temperature and provide the fluid with the correct amounts of oxygen and water vapor. In reducing the temperature of the fluid, heat may be extracted by suitable heat exchanges and utilized for auxiliary purposes. The gases used in the process are maintained below 350* C., the oxygen content of the gases is maintained below 17 percent and the water vapor content of the gases is maintained below 100 grams per kilogram of dry gases.
摘要:
A method for the isolation of specific molecules which bind highly selectively to chosen target molecules. In particular, due to displacement with a specific competitor, binding molecules are selected which preferably bind to previously known epitopes.

An improved electrical disconnect apparatus includes a set of spaced apart conductors and a removable conductive element that is structured to extend between the conductors and to complete at least a portion of an electrical circuit that includes the conductors. The electrical disconnect apparatus is situated between an electrical network and a network protector. The conductors and the conductive element which extends therebetween are situated within the interior of a support that is sealed in order to permit the electrical disconnect apparatus to be in a submerged environment during use. The conductive element is retained by a key interlock wherein the key that enables removal of the conductive element is stored on the network protector and is only made available to the technician when the network protector has been switched to an OFF condition.
摘要:
A box-shaped electric control cabinet is provided which can be closed by a cover and which is used to receive electric components and devices for a blade angle adjustment drive (pitch drive) of a wind energy power plant, by means of which one or more rotor blades of the plant can be rotated about the blade axis. The control cabinet includes at least two cabinet segments, and specific electric components and devices are associated with respectively each module according to its function. The cabinet segments can be associated with and/or assigned to respectively different electric components and devices, with which, combined as a part function, different total functions and/or embodiment forms of the control cabinet can be produced or are producible.
摘要:
A steam turbine has a two-shell housing, including an outer casing and an inner casing arranged therein, as well as a pipe that extends through the outer casing for supplying and/or removing steam to or from the inner casing, the pipe being provided with a pair of apertures arranged opposite each other on the inner casing. According to the invention, a first steam supply or discharge pipe can be connected to a first aperture, and the second aperture is closed by a cover.
