Abstract: An optical switch has a substrate and a transparent material in which a three-dimensional diffraction pattern is recorded which is capable of diffracting light, the material having non-linear optical properties and extending in the form of a first layer above the substrate. At least one first electrode and at least one second electrode are provided for varying the diffraction pattern in accordance with applied voltages.

Abstract: A kernel provides a mechanism allowing various applications (e.g. CRM, logistics, procurement, etc.) hosted on a plurality of different application servers, to share access to a common underlying system (e.g. database). An automated process for implementing a kernel change (e.g. for upgrade or replacement) may employ a “Stop-the-World” approach involving suspension of application server instances, coordinated by the start service of the last application server whose kernel is to be changed. As used herein, suspending refers to halting any processing prior to calling a central service (CS) as long as a CS instance is unavailable, and then to resuming processing once the CS instance becomes available. This suspension of relevant clients avoids errors from arising during the downtime of the CS instance. Once the application server instances are in a stopped state, the CS instance is restarted. Then, the application server instances are resumed, and their kernels are changed.

Abstract translation: 内核提供了允许托管在多个不同应用服务器上的各种应用（例如CRM，物流，采购等）共享对公共底层系统（例如数据库）的访问的机制。 用于实现内核更改（例如用于升级或更换）的自动化过程可以采用“停止世界”方法，其包括暂停应用服务器实例，由其内核被改变的最后一个应用服务器的启动服务进行协调。 如本文所使用的，挂起是指在CS实例不可用之前中断服务（CS）之前的任何处理，然后一旦CS实例变得可用，则恢复处理。 暂停相关客户避免在CS实例停机期间出现错误。 一旦应用程序服务器实例处于停止状态，则重新启动CS实例。 然后，应用服务器实例被恢复，并且它们的内核被改变。

Abstract: According to one general aspect, a method for managing a plurality of different tenants on a shared computing infrastructure including at least one application server apparatus may include associating a tenant with a plurality of services, wherein each service provides a set of actions that the service is configured to perform. In some embodiments, the method may include associating at least one tenant runlevel for each associated service with the tenant. In various embodiments, the method may include, when the application server apparatus executes a service for the tenant, determining the tenant runlevel associated with the tenant, and managing the set of actions configured to be performed by the service based at least in part upon the tenant runlevel associated with the tenant and the service.

Abstract: A system and method for connection failover. A plurality of virtual machines connect to a proxy using a protocol library. The proxy establishes a connection to a gateway. A user context including a conversation identifier is stored. The proxy continues a conversation with a second virtual machine based on the conversation identifier and user context if a first virtual machine fails when the conversation is in a ready for failover state.

Abstract: An optical duplexer, configured as a directional coupler, is integrated into an optical coupling arrangement with a fiber optic pigtail, constructed in planar-optical hybrid technology on a substrate (1). To reduce the required surface area and decrease optical cross talk, the branch of the directional coupler (waveguide 6, branch 7) is sharply bent. The bend is equipped with a reflecting mirror (11) integrated opposite the inner edge (10) of the bend. Furthermore, the waveguiding end of the bent branch (7) is equipped with a cylindrical lens. A laser diode (8) is located before this, and a photodiode (5) is located before the angled end of the straight-line integrated waveguide (2).
