Abstract: The present disclosure is directed to a device configured to detect whether the device is in a bag or outside of the bag. The device determines whether the device is in or outside of the bag based on distance measurements generated by at least one proximity sensor and motion measurements generated by at least one motion sensor. By using both distance measurements and motion measurements, the device is able to detect whether the device is in the bag or outside of the bag with high accuracy and robustness.

Abstract: A pointing electronic device is provided with: an inertial measurement module, to generate motion input data, indicative of motion of the pointing electronic device, at an input data rate; a pointing determination unit, to implement a pointing algorithm at a processing data rate based on the motion input data, to generate screen-frame displacement data corresponding to 3D-space movements of the pointing electronic device, the processing data rate being higher than the input data rate. The pointing electronic device is further provided with a rate upscaling unit, interposed between the inertial measurement module and the pointing determination unit, to implement a data-rate upscaling of the motion input data, in order to generate upscaled motion input data to be processed by the pointing determination unit at a data rate matching the processing data rate, via a predictive data reconstruction of missing samples based on the actual motion input data.

Abstract: An embodiment inertial measurement system includes: at least one motion sensor to output motion data with an output data rate (ODR) period; and a control unit coupled to the motion sensor to control operation thereof based on a power mode switching, according to which each ODR period includes: a first phase, in which the motion sensor is controlled in a condition of low power consumption; and a subsequent measurement phase, in which the motion sensor is controlled to perform measurements for generation of measurement data. The control unit adaptively adjusts the duration of the ODR period based on at least one check related to the measurement data generated during the measurement phase.

Abstract: An electronic device has an input which, in operation, receives an input stream of accelerometer data samples indicative of acceleration values along at least one axis. The devices includes circuitry, coupled to the input. The circuitry, in operation, executes an automatic-learning algorithm on blocks of samples of the input stream of accelerometer data samples to identify, for each block, a corresponding condition-of-user-movement from among a plurality of determined conditions-of-user-movement. The circuitry generates a plurality of streams of samples based on the input stream of accelerometer data samples, and for each condition of movement identified, selects a corresponding stream of samples of the plurality of streams of samples. The circuitry executes a wrist-tilt gesture detection algorithm using samples of the selected stream of the plurality of streams of samples.

Abstract: A system recognizes a gesture of bringing a mobile electronic device to a user ear. The system may be integrated in the mobile electronic device and is provided with a movement sensor which provides a movement signal indicative of the movement of the mobile electronic device. A pressure sensor provides a pressure signal indicative of a pressure acting on the mobile electronic device during the movement. A processing stage performs a joint processing of the movement signal and of the pressure signal in order to recognize the gesture.

Abstract: A remote access device and methods of operation thereof are provided for accessing a physical object or location. The remote access device includes an accelerometer, a wireless transmitter, and control circuitry. The control circuitry causes the wireless transmitter to transition between a first operating mode and a second operating mode in response to receiving signals from the accelerometer indicating a first change in motion states of the remote access device. The control circuitry causes the wireless transmitter to transition between a first operating mode and a second operating mode in response to receiving signals from the accelerometer indicating a second change in motion states of the remote access device. The control circuitry further causes the wireless transmitter to transition between the first operating mode and the second operating mode in response to receiving signals from the accelerometer indicating a third change in motion states of the remote access device.

Abstract: The present disclosure is directed to a device and method for lid angle detection that is accurate even if the device is activated in an upright position. While the device is in a sleep state, first and second sensor units measure acceleration and angular velocity, and calculate orientations of respective lid components based on the acceleration and angular velocity measurements. Upon the device exiting the sleep state, a processor estimates the lid angle using the calculated orientations, sets the estimated lid angle as an initial lid angle, and updates the initial lid angle using, for example, two accelerometers; two accelerometers and two gyroscopes; two accelerometers and two magnetometers; or two accelerometers, two gyroscopes, and two magnetometers.

Abstract: The present disclosure is directed to a detection method of a first or second state of a foldable electronic device including a first and a second hardware element tiltable to each other and accommodating a first and a second electrode which are in contact with each other when the foldable electronic device is in the first state and at a distance from each other otherwise. The detection method includes: acquiring a first and a second charge variation signal indicative of environmental electric/electrostatic charge variations detected by the first and second electrodes; generating a differential signal indicative of a difference between the first and the second charge variation signals; generating, as a function of the differential signal, one or more feature signals; and generating, as a function of the one or more feature signals, a contact signal indicative of the first or second states of the foldable electronic device.
