Abstract: The present disclosure relates to a distance measurement system The system comprises a transmitter device and a receiver device. The transmitter device and the receiver device are clock-synchronized to each other. The transmitter device is configured to emit an ultrasonic signal at one or more predefined transmit times known to the transmitter and the receiver device. The receiver device is configured to receive the ultrasonic signal and to estimate a distance between the transmitter device and the receiver device based on the received ultra-sonic signal and the one or more predefined transmit times.

Abstract: The present disclosure generally relates to authenticating a user of a mobile device based on motion data of said mobile device. Embodiments provide a method, apparatus and computer program for authenticating a user, a mobile device comprising such an apparatus and a system. The method comprises detecting an outfit of the user. The method comprises analyzing a gait of the user using a machine-learning model using motion data of a mobile device as input to the machine-learning model. The analysis is based on the identified outfit of the user. The method comprises authenticating the user based on the analysis of the gait of the user.

Abstract: A body simulator is disclosed. The body simulator includes a receiver configured to receive a signal based on sensor data including vocalization data from a subject, and a body which includes a breathing simulator and a vocalization simulator. The breathing simulator simulates the breathing of a subject. The vocalization simulator can simulate vocalization, audio, speaking, and/or vibrations associated therewith. The body simulator is configured to modulate the simulated breathing based on vocalization data.

Abstract: The present disclosure relates to a concept of proximity detection. A sequence of keystrokes is captured when a person types on a keyboard placed on a support structure. A sequence of vibrations of the support structure in response to typing on the keyboard is captured with a sensor device associated with a user or a location and in contact with the support structure in proximity to the keyboard. The proximity between the person and the sensor device is checked based on a comparison of the captured sequence of keystrokes with the captured sequence of vibrations.

Abstract: A method for authenticating a user of an electronic device is provided. The method includes displaying a section of a graphical representation to the user on a display of the electronic device. The graphical representation comprises a graphical object. Further, the method includes requesting the user to navigate to the graphical object. Additionally, the method includes capturing data from one or more sensors of the electronic device that is indicative of a movement of the electronic device by the user for navigating to the graphical object and/or data from one or more input devices of the electronic device that is indicative of a user input by the user for navigating to the graphical object. The method further includes authenticating the user based on the captured data.
