Abstract: A device includes one or more motion sensors and processing circuitry coupled to the one or more motion sensors. The one or more sensors, in operation, generate motion sensor signals. The processing circuitry, in operation, classifies a user-activity type based on the motion sensor signals, the user-activity type being selected from a plurality of user-activity types including one or more moving activity types, detects a tilt angle of the device based on the motion sensor signals, and classifies a use-condition of the device as used or not used based on the detected tilt angle. The processing circuitry generates a use-warning signal based on whether the classification of the user-activity type is a moving activity type and on whether the classification of the use-condition is used. The device may include an integrated circuit including the motion sensors and the processing circuitry, and the integrated circuit may be embedded in a display.

Abstract: The present disclosure is directed to a device for detecting the passage of an infrared, IR, radiation emitting body in a monitoring zone. The device has a first surface and a second surface mutually tilted and configured to face the monitoring zone. The device includes a first IR radiation sensor extending on the first surface and a second IR radiation sensor extending on the second surface. The first IR radiation sensor is configured to detect the IR radiation of the emitting body when the emitting body is in a first field of view of the first IR radiation sensor and the second IR radiation sensor is configured to detect the IR radiation of the emitting body when the emitting body is in a second field of view of the second IR radiation sensor. The first and the second fields of views are configured to be partially superimposed on each other at the monitoring zone.

Abstract: Provided is a measuring device for measuring a distance between the measuring device and a user. The measuring device includes a distance sensor configured to generate a distance signal indicative of the distance, an IR radiation sensor configured to generate a temperature signal indicative of the IR radiation emitted by the user, and a control unit. The control unit is configured to: in a calibration mode, acquire the distance signal and the temperature signal respectively through the distance sensor and the IR radiation sensor and, on the basis of the distance signal and the temperature signal, generate a calibration curve which associates to each other values of the temperature signal with respective value of the distance; and in a calibrated mode, acquire the temperature signal through the IR radiation sensor and, on the basis of the temperature signal and the calibration curve, determine the distance.

Abstract: The present disclosure is directed to human presence detection with an infrared sensor. The human presence detection utilizes signal regularization and edge detection to minimize the effect of drift on the human presence detection. The human presence detection is accurate regardless of changes in ambient temperatures.

Abstract: The present disclosure is directed to lift-up gesture detection for electronic devices. An initial lift-up gesture is detected in response to an orientation change and a lift-up motion of the device being detected. The initial lift-up gesture is validated as a true lift-up gesture in a case where a shaking motion of the device is not being detected when the initial lift-up gesture is detected. If a shaking motion of the device is detected when the initial lift-up gesture is detected, the initial lift-up gesture is rejected.

Abstract: A crash detection system includes first and second sensors and a processor. The processor receives first sensor data output by the first sensor, determines whether the first sensor data indicates a first class or a second class, outputs an enable signal to the second sensor if the first sensor data indicates the second class, receives second sensor data output by the second sensor after the enable signal is output, determines whether the second sensor data indicates a high acceleration value, determines whether the first sensor data indicates the first class within a predetermined amount of time after the second sensor data is determined to indicate the high acceleration value, and outputs a signal indicating a crash has occurred in response to determining that the first sensor data indicates the first class within the predetermined amount of time after the second sensor data is determined to indicate the high acceleration value.
