Abstract: A method for calculating a trajectory of an object with a low resolution time of flight sensor with pixels arranged in lateral directions next to one another includes providing measurement values of the pixels for different time frames. The method also includes determining a user layer dependent on the measurement values. The method further includes determining that the object is between the user layer and the time of flight sensor dependent on the measurement values. The method additionally includes calculating for every time frame a position in lateral directions of the object with a weighted average function dependent on the measurement values. The positions in lateral directions of the object are representative for the trajectory of the object.

Abstract: A method for predicting a vital sign of a person comprises recording a time series of a bio signal of a person as a first dataset, obtaining a demographic data of the person, extracting a feature vector from the first dataset using a machine-learning based feature extractor, generating an embedding vector from the demographic data using an embedding model, and predicting a vital sign of the person from the feature vector and the embedding vector using a machine-learning based regressor.

Abstract: A method for secure viewing on a screen of an electronic terminal includes determining a mode of operation, secured or open, of the terminal; and modifying the displaying of at least one indicator representing the mode of operation of the terminal. The displaying modification is controlled by at least one secure processor of the terminal and takes into account at least one predetermined action of the user on the terminal and/or of an expiration of at least one predetermined time limit.
