Abstract: A system for providing communications services, comprising a first wireless communication network with a MCPTT infrastructure suitable for MC PTT communication and a relay which transmits the communication to a second wireless network in which terminals which participate in MCPTT communication are registered as MCPTT clients, characterized in that the relay takes over the data exchange necessary for setting up MCPTT voice communication, avoiding the MCPTT clients being involved in the data exchange with the MCPTT server.

Abstract: The present invention relates to a mobile terminal which comprises a mobile telephone and an additional device. In this case, the additional device comprises a second communication module, wherein the second communication module is designed such that it enables, as a participant of a WLAN network, a wireless third communication connection to this WLAN network.

Abstract: Group communication system comprising at least three communication devices, preferably a multiplicity of communication devices, wherein the communication devices communicate in at least one radio network directly, without the interposition of a static transmitting/receiving station, wherein each communication device provides a communication channel at least for the transmission of a sound, in particular voice, signal, wherein each communication device comprises at least one sensor for capturing data, in particular a motion sensor and/or temperature sensor and/or a tactile sensor and/or . . . , and provides a data channel for transmitting sensor data and/or signals on the basis of sensor data.

Abstract: The invention relates to a dental splint as an assembly comprising a first subassembly embodied as a dental splint body and having a surface that comes into contact with an oral cavity of a user, a second subassembly embodied as electronics, at least one third subassembly embodied as a sensor, a fourth subassembly embodied as an energy source, at least one fifth subassembly embodied as an antenna, and a sixth subassembly embodied as electrical connection means, wherein the second to fifth subassemblies are connected by the sixth subassembly. In this case, at least one of the second to sixth subassemblies is produced in each case completely or partly in a 3-D printing method.

Abstract: The present invention relates to an apparatus for monitoring and/or controlling an animal, in particular a horse, by repeatedly recording at least one vital function and/or a movement behavior of the animal.
