    • The present invention relates to a method to supply power to an LED array, comprising at least two LED branches connected in parallel, in each of which at least one LED is arranged. The LED array is supplied with predetermined power from a current source connected in series, wherein currents are measured in the LED branches, wherein the measured currents are compared in control electronics, and wherein the currents are controlled in a part of the LED branches such that they have a defined ratio with respect to one another in the LED branches. The method is intended to be improved such that it can be carried out economically and with simple means. This is achieved in that one of the LED branches is selected to be the master whose current is utilized as the target specification for the remaining LED branches.The invention further relates to a circuit arrangement for implementing the method according to the invention as well as a lighting unit with such type of circuit arrangement.

    • A shredder includes a rotor supporting a plurality of multi-point cutters that mesh with a counter-knife having generally V-shaped grooves. Each cutter has at least one corner defined by an intersection between two contiguous side faces of the body of the cutter. The corner defines a plurality of cutting points spaced apart along a first direction. The cutters are mounted on the outer peripheral surface of the rotor such that the first direction of each cutter is substantially tangent to the outer peripheral surface, and such that the corners of the cutters mesh with respective V-shaped grooves in the counter-knife as the rotor rotates about its axis. The multiple points of each cutter encounter and mesh with the groove in the counter-knife in a sequential fashion.

    • The present disclosure provides a method that efficiently produces (6R)-tetrahydrobiopterin in high yield and purity. The method includes the step of hydrolyzing diacetylbiopterin to biopterin under basic conditions in a biphasic mixture comprising an organic phase and an aqueous phase. After substantially complete hydrolysis of diacetylbiopterin, the aqueous phase containing biopterin can be separated from the organic phase containing most of the organic impurities, which avoids the time-consuming step of isolating biopterin as a solid. The aqueous solution containing biopterin is stereoselectively hydrogenated to (6R)-tetrahydrobiopterin under basic conditions and high hydrogen pressure in the presence of a metal catalyst (e.g., a platinum catalyst). To improve the purification of an acid addition salt of (6R)-tetrahydrobiopterin (e.g., (6R)-tetrahydrobiopterin dihydrochloride), any residual salts (e.g., sodium salts) in the aqueous solution after the hydrogenation reaction can be removed by contacting the aqueous solution with an ion (e.g., cation) exchange resin or column. Alternatively, removal of residual salts from the aqueous solution can be omitted if an organic amine (e.g., diethylamine or triethylamine) rather than an inorganic base is used in the hydrolysis and/or hydrogenation reactions.
    • 本公开提供了以高产率和纯度有效生产（6R） - 四氢生物蝶呤的方法。 该方法包括在碱性条件下在包含有机相和水相的两相混合物中将二乙酰生物蝶呤水解成生物蝶呤的步骤。 在二乙酰生物蝶呤基本上完全水解后，含有生物蝶呤的水相可以从含有大部分有机杂质的有机相中分离出来，这避免了将生物蝶呤分离成固体的耗时的步骤。 含有生物蝶呤的水溶液在碱性条件下，在金属催化剂（如铂催化剂）存在下，氢压高，立体选择氢化为（6R） - 四氢生物喋呤。 为了改善（6R） - 四氢生物蝶呤（例如（6R） - 四氢生物喋呤二盐酸盐）的酸加成盐的纯化，氢化反应后的水溶液中的任何残留盐（例如钠盐）可以通过使水溶液 溶液与离子（如阳离子）交换树脂或色谱柱。 或者，如果在水解和/或氢化反应中使用有机胺（例如二乙胺或三乙胺）而不是无机碱，则可以从水溶液中除去残留的盐。

    • The method of the invention is based on an optimum combination of multi-carrier modulation with the spread-spectrum technique. The data of a subscriber station are spread, with the data of a subscriber station being modulated on a set of orthogonal spread sequences and superimposed. The data of a subscriber station are transmitted to a partial quantity of subcarriers in the frequency band, with the partial quantity of sub-carriers associated with the individual subscriber stations being disjunct and distributed over the entire transmission band. A channel estimation required for receiving-side data detection is performed by means of filtering in the time and/or frequency direction of reference symbols. A low-complexity maximum-likelihood sequence estimation is possible for data detection. The method of the invention is well-suited for use for both the upstream and downlinks in future cellular mobile-radio systems.
    • 本发明的方法是基于多载波调制与扩频技术的最佳组合。 用户站的数据被扩展，用户站的数据被调制在一组正交扩展序列上并叠加。 用户站的数据被发送到频带中的部分子载波数量，与各个用户站相关联的子载波的部分数量分散在整个传输频带上。 通过在参考符号的时间和/或频率方向上的滤波来执行接收侧数据检测所需的信道估计。 对于数据检测，低复杂度最大似然序列估计是可能的。 本发明的方法非常适用于将来的蜂窝移动无线电系统中的上行链路和下行链路两者。
