    • A high-pressure gas discharge (HID, high intensity discharge) lamp is described, having a discharge vessel (1) that contains a metal that is applied at least to parts of those regions of the feedthroughs and/or walls of the discharge vessel (1) at which condensation of ingredients of the gas filling may occur as a result of a temperature sink that occurs when the lamp is in a state of operation. In this way, it is possible to at least largely prevent not only chemical interactions between ingredients of the gas filling (particularly the metal halides) and the relevant regions of the feedthroughs or walls at which, due to the lower temperature of these regions, the ingredients condense, but also losses of ingredients of this kind from the gas filling. This in turn means that there is no risk of any damage to the lamp or of any degradation of its lumen maintenance.

    • A method of manufacturing a grid (1) for selective transmission of electromagnetic radiation, particularly X-ray radiation, is proposed. The method comprises: providing a support element (3) having self-supporting stability, wherein the support element (3) is made with a material which essentially absorbs no electromagnetic radiation to be selectively transmitted through the grid; applying a metal layer (5) at a surface of the support element (3); and building a selective transmission structure (7) at a surface of the metal layer (5) with a material which absorbs electromagnetic radiation to be selectively transmitted through the grid, wherein the transmission structure is build using selective laser sintering. As the support element (3) provides sufficient mechanical stability but does not absorb the respective radiation, the selective transmission structure (7) build thereon using selective sintering might not have to be subsequently separated from a manufacturing substrate thereby preventing separation/dicing losses and, furthermore, might be structurally held and protected against damage during handling of the grid.
    • 提出了一种用于选择性地传输电磁辐射的网格(1)的制造方法,特别是X射线辐射。 该方法包括:提供具有自支撑稳定性的支撑元件(3),其中所述支撑元件(3)由基本上不吸收电磁辐射的材料制成,以选择性地透过所述栅格; 在所述支撑元件(3)的表面上施加金属层(5); 以及通过吸收电磁辐射的材料在所述金属层(5)的表面上建立选择性透射结构(7)以选择性地透过所述栅格,其中所述透射结构使用选择性激光烧结来构建。 由于支撑元件(3)提供足够的机械稳定性但不吸收相应的辐射,所以使用选择性烧结的选择性透射结构(7)可能不必随后与制造基板分离,从而防止分离/切割损失, 此外,可以在结构上保持和保护在处理电网期间的损坏。

    • A secure solution is provided to the problem of secret key agreement. In particular, a method of reliable forward secret key sharing is disclosed between two legitimate correspondents whose profiles match sufficiently. The invention relies on a physical random function, sometimes referred to as a physical unclonable function (PUF) to provide a secure solution to the problem of secret key agreement. In one embodiment, a one-pass protocol is introduced based on Reed-Solomon codes leading to an unconditionally secure solution. In a further embodiment, the solution of the first embodiment is improved upon by providing a conditionally secure solution based on a pseudo random family of functions. In a still further embodiment, a two-pass protocol is introduced which is used exclusively for purposes of identification and authentication. In accordance with the principles of the two-pass protocol, two communications are required and unlike the one-pass protocol, the second correspondent selects the secret key K.
    • 为密钥协商的问题提供了一个安全的解决方案。 特别地,在两个合法记者之间公开了一种可靠的前向密钥共享方法,这两个通信者的配置文件足够匹配。 本发明依赖于物理随机功能,有时被称为物理不可克隆功能(PUF),以提供密钥协商问题的安全解决方案。 在一个实施例中,基于Reed-Solomon码引入一通路由协议,导致无条件的安全解决方案。 在另一实施例中,通过提供基于伪随机函数族的有条件的安全解决方案,改进了第一实施例的解决方案。 在又一个实施例中,引入了专门用于识别和认证的双向协议。 根据双程协议的原理,需要两个通信,并且与一通协议不同,第二通信对象选择秘密密钥K.
