摘要:
A high-temperature pressure sensor element for power units includes a substrate, in which an interior space is developed, a deformable membrane, which separates the interior space from the exterior space in order to deform when the exterior pressure changes, and a strain measuring element, which is arranged on the membrane, for measuring the deformation of the membrane. The substrate, the membrane, and the strain measuring element are manufactured from the same high-temperature-stable material, such as an alloy. By way of example a nickel base alloy may be used. A component for a power unit, such as a turbine blade for an airplane or rocket engine, includes an integrated high-temperature pressure sensor element of this type.

摘要:
An electron beam is used to generate x-ray radiation in a workpiece, which radiation emerges on the workpiece back at sufficiently thin points of the workpiece and is detected by means of an x-ray radiation detector. Based on the x-ray radiation intensity and the momentary beaming-in position of the electron beam, the surface structure on both sides as well as the local material thickness can be determined. Based on such values, workpieces and/or workpiece treating systems can be adjusted, and vertical material removal in a material-removing workpiece treating system can be controlled.

Cells having cavities and the manufacture and use of the same are described. An example cell includes a first layer including a gap to at least partially define a cavity and a reservoir area to receive material to enter the cavity by diffusion. Additionally, the cell includes one or more other layers coupled to the first layer to at least partially define the cavity and to hermetically seal the cavity from an exterior environment.

The invention relates to a ceramic substrate material having a first layer having a cavity structure formed therein, and at least one sealing layer situated on at least a part of the cavity structure. The first layer comprises at least one first component made of a crystalline ceramic material and/or a glass material as a matrix, the first layer containing a second component made of a further crystalline ceramic material, with selected mantle areas of the crystals and/or crystal agglomerates of the second component being etched out in such a way that the cavity structure is provided (preferably in the form of a pore and/or tube structure). The sealing layer seals the surface of the first layer in the areas on which it is situated (e.g., above the cavity structure), allowing application of thin-film structures to the cavity structure.

A unique and cost-effective method for producing a multilayer ceramic structure by using a first green film that contains a ceramic material, and the multilayer ceramic structure produced thereby. The method including the steps of:(a) producing at least one porous region in the first green film, the at least one porous region extending from the surface of the first green film;(b) applying a first layer, in sections, to the surface of the first green film, wherein one section of the first layer is located above the at least one porous region produced in step (a);(c) positioning at least one additional green film on the surface of the first green film, to which the first layer has been applied;(d) laminating the first green film and the at least one additional green film to form a green film composite; and(e) sintering the green film composite.
摘要:
The invention relates to a method for distributed, fault-tolerant clock pulse generation in hardware systems, wherein the system clock pulse is generated in distribution by a plurality of intercommunicating fault-tolerant clock pulse synchronization algorithms (TS-Algs), in which an arbitrary number of such TS-Algs exchange information between one another via a user-defined and permanent network (TS-Net) of clock pulse signals, susceptible to transient faults, and each TS-Alg is assigned to one or more functional units (Fu1, Fu2, . . . ), whose local clock pulses are generated by it, and further all local clock pulses are synchronized with respect to frequency in an assured manner, and a specified number of transient and/or permanent faults may occur in the TS-Algs or in the TS-Net, without adversely affecting the clock pulse generation and/or the synchronization accuracy, and the system clock pulse automatically achieves the maximum possible frequency. The invention further relates to such a hardware system.
摘要:
A method for producing a ceramic substrate material having a first layer and possibly a further layer is specified. The first layer comprises at least one first component made of a crystalline ceramic material and/or a glass material as a matrix and a second component made of a further crystalline ceramic material, which is provided in the matrix. An etching step is performed, mantle areas of the crystals and/or crystal agglomerates of the second component being etched selectively in the first layer to generate a cavity structure in the first layer. The present invention also relates to a corresponding ceramic substrate material, an antenna or an antenna array, and the use of the ceramic substrate material for an antenna or an antenna array.

A stress reduction system includes a plurality of devices designed to relieve anxiety through the five senses: smell, touch, sight, sound and taste. The system preferably takes the form of a kit, wherein each of the devices works on at least one of the primary senses in a therapeutic and relaxing manner to calm a person and place them more at ease in a stressful environment. A downloadable software “app” on a phone or tablet may include instructions on the proper use of the various relaxation devices in the kit, as well as breathing instruction, meditation techniques, self-hypnosis steps and instruction, or other types of mental or therapeutic exercises that are used to calm the body and the mind. The kit may include a variety of other sensory items, such as ear buds, cooled eye shades, foods with natural extracts used for relaxation, and aromatic pins.
