    • Semiconductor laser diodes, particularly broad area single emitter (BASE) laser diodes of high light output powers are commonly used in opto-electronics. Light output power and stability of such laser diodes are of crucial interest and any degradation during normal use is a significant disadvantage. The present invention concerns an improved design of such laser diodes, the improvement in particular significantly minimizing or avoiding (front) end section degradation at very high light output powers by controlling the current flow in the laser diode in a defined way. This is achieved by controlling the carrier injection, i.e. the injection current, into the laser diode in a novel way by creating single current injection points along the laser diode's longitudinal extension, e.g. along the waveguide. Further, the supply current/voltage of each single or group of current injection point(s) may be separately regulated, further enhancing controllability of the carrier injection.
    • 半导体激光二极管,特别是具有高光输出功率的广域单发射器(BASE)激光二极管通常用于光电子。 这种激光二极管的光输出功率和稳定性是至关重要的,并且在正常使用期间的任何劣化是显着的缺点。 本发明涉及这种激光二极管的改进设计,特别地通过以限定的方式控制激光二极管中的电流而在非常高的光输出功率下,特别地显着地最小化或避免(前)端部部分退化的改进。 这通过以新颖的方式通过沿着激光二极管的纵向延伸,例如通过产生单电流注入点来控制载流子注入即注入电流来实现。 沿着波导。 此外,每个单个或一组电流注入点的供电电流/电压可以单独调节,进一步增强了载流子注入的可控性。

    • A system for updating advertisement bids including a query engine and an advertisement selection engine. The query engine provides an advertisement query to the advertisement selection engine. The advertisement selection engine includes a query processing module that retrieves advertisements associated with the advertisement query based on bids. The bid update module generates a suggested bid for an advertiser. The bid update module may be configured to automatically update the current bid for an advertisement based on the suggested bid. Further, the bid update module may be configured to determine the suggested bid by calculating a maximum profit position for the advertisement and projecting an envy free point for the maximum profit position.
    • 一种用于更新广告投标的系统,包括查询引擎和广告选择引擎。 查询引擎向广告选择引擎提供广告查询。 广告选择引擎包括查询处理模块,其基于出价检索与广告查询相关联的广告。 出价更新模块为广告客户生成建议的出价。 出价更新模块可以被配置为基于所建议的出价自动地更新广告的当前出价。 此外,出价更新模块可以被配置为通过计算广告的最大利润位置并且为最大利润位置投射嫉妒点来确定建议的出价。
