Abstract: Various embodiments of the teachings herein include systems and methods for monitoring the posture of a user during use of an electronic device. An example includes: reading an image from a camera associated with the electronic device; determining a value representing the posture shown in the image; and transmitting a warning signal if the value falls in a warning range.

Abstract: Various embodiments of the teachings herein include a speech synthesizer. An example includes: a processor with a speech analysis module to analyze and process natural language for content and an emotional module to perform emotional modeling of the utterance; a neural network with an AI system; a microphone; and a memory storing a recording of natural and/or artificially spoken speech as acoustic data. The processor receives, analyzes, and processes the acoustic data stored in the memory. The neural network provides a suggestion for the emotional modeling with regard to content of the utterance. The AI system develops a suggestion for the emotional modeling on the basis of appropriate training data at least partly generated by human interaction.

Abstract: A system and method are provided for aligning a field of view (FOV) of a movable part of a medical device with a desired region on a subject's body. In the system, a position detecting unit detects an identifiable optical front projected on the subject's body and at least partially overlapping with the desired region and generates information corresponding to a spatial position of the identifiable optical front. From the information, a processing module determines the spatial position of the identifiable optical front with respect to a known position of the FOV and generates an instruction set that corresponds to one or more mechanical adjustments of the movable part to change a position of the FOV from the known position to the spatial position of the identifiable optical front. An executing module directs a moving mechanism of the movable part to carry out mechanical motions according to the instruction set.
