摘要:
A method for local contacting and local doping of a semiconductor layer including the following process steps: A) Generation of a layer structure on the semiconductor layer through i) application of at least one intermediate layer on one side of the semiconductor layer, and ii) application of at least one metal layer onto the intermediate layer last applied in step i), wherein the metal layer at least partly covers the last applied intermediate layer, B) Local heating of the layer structure in such a manner that in a local region a short-time melt-mixture of at least partial regions of at least the layers: metal layer, intermediate layer and semiconductor layer, forms. After solidification of the melt-mixture, a contacting is created between metal layer and semiconductor layer. It is essential that in step A) i) at least one intermediate layer designed as dopant layer is applied, which contains a dopant wherein the dopant has a greater solubility in the semiconductor layer than the metal of the metal layer.

A method for transparently directing data in a multi-GPU system. A driver application receives a first plurality of graphics commands from a first graphics application and selects a first GPU from the multi-GPU system to exclusively process the first plurality of graphics commands. The first plurality of graphics commands is transmitted to the first GPU for processing and producing a first plurality of renderable data. The first plurality of renderable data is stored in a first frame buffer associated with the first GPU. A second plurality of graphics commands is received from a second graphics application and a second GPU is selected to exclusively process the second plurality of graphics commands. The second GPU processing the second plurality of graphics commands produces a second plurality of renderable data. The second plurality of renderable data is stored in a second frame buffer associated with the second GPU.

A sealed insulating glass unit comprises two glass sheets held apart by a spacer, optionally with a sealant between the edges of the glass sheets outside the spacer. The insulating glass unit contains an electronic device, having information relating to the origin, manufacture and/or properties of the insulating glass unit capable of being read from the device by means actuated from outside the insulating glass unit. The device is embedded within the spacer or sealant so that it is concealed within the insulating glass unit.

The invention proposes a method for producing a semiconductor component, such as a thin-layer solar cell. The method involves providing a doped semiconductor carrier substrate (1), producing a separating layer (2), for example a porous layer, on one surface of the semiconductor carrier substrate, depositing a doped semiconductor layer (3) over the separating layer and detaching the deposited semiconductor layer from the semiconductor carrier substrate. In line with the invention, process parameters such as the process temperature and time are chosen during the manufacturing process such that dopants can diffuse from the separation layer into the deposited semiconductor layer in order to form a specifically doped surface area (4). Specific use of solid-state diffusion makes it possible to simplify the manufacturing process over conventional fabrication methods in this manner.

The present invention relates to compositions comprising polypeptides, especially polypeptides capable of specifically binding predetermined antigens. The polypeptide in the composition comprises at least two antigen binding sites. These at least two antigen binding sites are located on a single polypeptide chain. One of the at least two antigen binding sites specifically binds the human CD3 antigen. The polypeptide may exist in both monomeric form and multimeric form. The multimeric form of the polypeptide constitutes no more than 5% of the total weight of the combined monomeric and multimeric forms of said polypeptide.

The invention relates to a method for detecting cornering for a vehicle (2) with automatic transmission. According to the invention it is proposed that the current bend radius be determined from the rotational speed signals of the front wheels, that the beginning of a cornering mode be determined when the current bend radius falls below a first limit bend radius and the end of a cornering mode be determined when the vehicle has covered a presettable distance after exceeding a second limit bend radius.

The invention relates to a method for determining a starting gear step for a vehicle with a multi-speed stepped variable transmission, wherein the starting gear step is determined by an electronic control device which is dependent on the vehicle mass; and a second variable which depends on the vehicle state is determined from the vehicle mass, the current traction and the current vehicle acceleration resulting therefrom.
摘要:
The transmission path (4) is fed with a test signal (M'), which is generated from a sequence (m) of spectral components (S1 . . . S10), which are distributed equidistantly in the frequency domain, as the result of combining with an additional function (ZSF). The additional function (ZSF) is selected so as to allow the test signal (M') to contain, besides the spectral components (S1 . . . S10)of the sequence (m), additional spectral components (ZS1 . . . ZS21). An output signal (M") received on the output side of the path is evaluated at evaluation frequencies (AW1 . . . AW10), in the case of which the test signal (M') is free per se of spectral components and, in the case of which, the test signal (M'), after a self-convolution, exhibits additional spectral components (SA1 . . . SA10). The additional spectral components (SA1 . . . SA10) occurring at the evaluation frequencies (AW 1 . . . AW 10) allow a non-linearity of the transmission path (4) to be immediately detected.
