A method features receiving a data stream (DS) having video and audio data; detecting a specific position within the DS classified by a predefined criterion (PC) and received by user's clients matching the PC; connecting the receiver not matching the PC with a client-server system matching the PC; receiving the DS by the client-server system and forwarding it to the receiver; extracting the video data and the audio data from the DS stream; creating a screenshot out of the video data and an associated timestamp; feeding the screenshot to an AI-system trained to detect whether it belongs to a predefined category; generating audio data corresponding with the screenshot and analyzing it for detecting whether it belongs to the predefined category; and if both the screenshot and the audio data generated / analyzed belong to the predefined category, then deciding that the associated timestamp for the screenshot defines the specific position.

The invention relates to a computer-implemented method for operating a technical device by means of a client-server system, comprising a server (S) and clients (C1-C3) which are connected to one technical device (TD1-TD3) each, each technical device (TD1-TD3) keeping available a performance indicator for describing the technical performance capability in a specified future time interval, and the following steps being carried out: a) each client (C1-C3) carrying out a respective training for a provided respective local model (LM1-LM3) for operating the respective technical device (TD1-TD3) with at least one subset of provided training data, the size of the at least one subset of provided training data being defined by the performance indicator, b) the clients (C1-C3) providing the respective local models (LM1-LM3) to the server (S), c) the server aggregating the local models (LM1-LM3) to form a global model (GM), and providing the global model (GM) to the clients (C1-C3), d) each client (C1-C3) receiving the global model (GM), and updating the local model (LM1-LM3) by means of the previously received global model (GM), e) operating the technical device (TD1) by means of the previously updated local model (LM1-LM3).

In a client server system according to the present invention, a plurality of edge computers are accommodated by a line concentration switch and connected to a server via a network. Each edge computer of the plurality of edge computers is configured to acquire data by polling at a predetermined polling interval and transfer the data acquired by polling to the server via the network in a time slot allocated at the polling interval, and determines the start time of the time slot on the basis of a time corrected by using a round trip time measured by negotiation with the server and a reference time distributed from the server.

Proposed is a computer-implemented method for operating a technical apparatus by means of a client-server system having a server and clients that are connected to respective technical apparatuses, said method comprising the following steps: a. providing operational data from the operation of the technical apparatus of each client, and generating operational meta-information relating to the operation of the technical apparatus from the operational data using a provided, trained feature extraction model, by means of the server; b. providing a trained base model to the server, and applying the operational data and the meta-information relating to each client to the base model and obtaining associated operational features, by means of the server; c. calculating the similarity between the operational features of the respective clients in the form of a similarity value; d. assigning the client to a particular client group from a set of client groups, each client group from a set of client groups being defined by means of an associated specified value range for the similarity value of the particular client group; e. determining the largest client group, which has the most clients, from a set of client groups; f. forming the average similarity value from the respective similarity values of the clients in the largest client group; g. defining a personalization factor for each client on the basis of the average similarity value, which expresses a similarity of the particular client to the average similarity value of the associated largest client group; h. generating global model parameters for each client on the basis of the associated personalization factor and the difference between the associated operational data and the global model parameters; i. updating the base model using the global model parameters; j. continuing with step c) until a predetermined criterion for the repetition of steps c) - i) has been satisfied, and otherwise continuing with step k); and k. operating the technical apparatus with the updated base model.

A digital telecommunications client-server system for globally collecting, routing and distributing emergency alerts. An application client intercepts a Cell Broadcast emergency alert received by the terminal and forwards a copy of the alert with its parameters and along with other terminal and SIM information to the application server. The application server routes the received copy of the emergency alert to interested users, systems or third parties. The application server stores copies of received such cell broadcast emergency alerts forwarded by application clients, recognizes unique alerts, assigns to each of them a unique alert identifier, stores them in its alert registry and maintains up-to-date alert history and statistics. Without using the application server, a user with an application client can autonomously route intercepted emergency alerts to other interested users, systems or third parties.
