Abstract: An Optical Wireless Communication, OWC, front end (300) comprises a reflective splitter (310). The reflective splitter (310) has a controller port (311) for optical coupling to a controller (200) which generates OWC signals, and the reflective splitter (310) has a plurality of user ports (312) for optical coupling to OWC endpoint devices (400). The reflective splitter (310) is constructed and arranged such that: light received at the controller port (311) is passed to one or more of the user ports (312) for transmission to one or more OWC endpoint devices (400) in optical wireless communication with that user port (312); and light received at any of the user ports (312a) is passed to at least one other of the user ports (312b, 312c) for transmission to one or more OWC endpoint devices (400) in optical wireless communication with that user port (312b, 312c).

Abstract: A method for obstacle detection for a rail vehicle includes determining a monitoring region in front of the vehicle based on position and course of a track which the vehicle travels and position and dimensions of a monitoring profile of the vehicle. During the determination, sensor data for determining position and orientation of the vehicle are captured and position and course of the track which the vehicle travels are determined based on alignment of the determined position and orientation of the vehicle with digital map data. Objects in the vehicle environment are captured by sensors of the vehicle. Which objects are potential collision obstacles is determined by checking whether and to what extent they overlap with the monitoring region. A reaction to the objects categorized as potential obstacles is determined based on geometric and kinetic attributes of the objects. An obstacle detection device and a vehicle are also provided.

Abstract: A tank for the storage of liquid or gaseous substances with a fiber-reinforced plastic sheathing, which limits at least one interior space for holding the materials to be stored. At least one circumferential section of the fiber-reinforced plastic sheathing comprises an evacuable sandwich structure, which completely encloses the circumferential section. As a result, the tank has a low weight with a high thermal insulation capacity. Furthermore, a reliable explosion protection of the tank is provided. Furthermore, a method for manufacturing a tank for the storage of liquid or gaseous substances is provided.

Abstract: Systems and methods may be used to provide transcription and translation services. A method may include initializing a plurality of user devices with respective language output selections in a translation group by receiving a shared identifier from the plurality of user devices and transcribing the audio stream to transcribed text. The method may include translating the transcribed text to one or more of the respective language output selections when an original language of the transcribed text differs from the one or more of the respective language output selections. The method may include sending, a user device in the translation group, the transcribed text including translated text in a language corresponding to the respective language output selection for the user device. In an example, the method may include customizing the transcription or the translation, such as to a particular topic, location, user, or the like.

Abstract: A hydrogen tank having a tank structure at least partially delimiting a tank space and comprising a cooling shield formed in a lightweight construction. A conduit system, connected to the tank space, of a pressure relief system for discharging gaseous hydrogen from the tank space is formed in the cooling shield. At least one para-ortho catalyst for accelerated conversion of parahydrogen into orthohydrogen is arranged in the conduit system. A vehicle is provided having a hydrogen drive and such a hydrogen tank. A method for cooling the tank structure of such a hydrogen tank is provided.

Abstract: There is provided an apparatus comprising at least one processor and a memory comprising code that, when executed on the at least one processor, causes the apparatus to receive an input user setting relating to relative volumes of the speech data in a preferred language and speech data in a non-preferred language when the speech data is played-out; and cause play-out of received speech data so that the volume of the played-out speech data is set in dependence on the user input and whether the received speech data is in the preferred language or the non-preferred language.

Abstract: Method and apparatus are utilized in a system for distributing digital contents from a central server to a plurality of endpoint servers for further distribution to end users for automatically managing the digital assets of the endpoint servers. Each endpoint server is connected to a plurality of users over a communications network and operable to deliver digital information content to users on demand. Using a master content stored at the central server, the digital content of each endpoint is periodically and automatically refreshed based on an aggregate profile that reflects the preferences of the end-user population served by the endpoint server. The aggregate profile is generated from information received from the end users, including information submitted by the users or automatically generated feedback information relating to the users'on-line activities.
