摘要： The present disclosure is directed to a device with enhanced human activity recognition. The device detects a human activity using one more motion sensors, and enhances the detected human activity depending on whether the device is in an indoor environment or an outdoor environment. The device utilizes one or more electrostatic charge sensors to determine whether the device is in an indoor environment or an outdoor environment.

摘要： Digital signal processing circuitry, in operation, determines, based on accelerometer data, a carry-position of a device. Double-tap detection parameters are set using the determined carry-position. Double-taps are detected using the set double-tap detection parameters. In response to detection of a double-tap, control signals, such as a flag or an interrupt signal, are generated and used to control operation of the device. For example, a device may enter a wake mode of operation in response to detection of a double-tap.

摘要： A method is provided for controlling an electronic apparatus on the basis of a value of a lid angle between a first hardware element accommodating a first magnetometer and a second hardware element accommodating a second magnetometer. The method includes acquiring, through the magnetometers, first signals representing an orientation of the hardware elements. A calibration parameter indicative of a condition of calibration of the magnetometers is generated on the basis of the first signals. A reliability value indicative of a condition of reliability of the first signals is generated on the basis of the first signals. A first intermediate value of the lid angle is calculated on the basis of the first signals. A current value of the lid angle is calculated on the basis of the calibration parameter, of the reliability value, and of the first intermediate value, and the electronic apparatus is controlled on the basis of the current value.

摘要： Technological advancements are disclosed that utilize inertial sensor data associated with a device to determine a new feature array and if the new feature array is within an existing class within a state space associated with the inertial sensor data. In response to the new feature array being included in the existing class, the new feature array is added to the existing class and a representation of the existing class in the state space is updated based on the new feature array and an existing representation of the existing class. In response to the new feature array not being included in the existing class, a new class is created based on the new feature array.

摘要： The present disclosure is directed to a method for detecting a liquid on a main surface of a body. The method is performed through a detection device including a processing module, a reference electrode at a reference electric voltage and a first sensing electrode on the main surface and configurated to detect an environmental electric and/or electrostatic charge variation indicative of the presence of the liquid. The method includes the steps of: biasing the first sensing electrode to a bias electric voltage; while the first sensing electrode is at the bias electric voltage, acquiring a first charge variation signal indicative of the electric and/or electrostatic charge variation detected by the first sensing electrode; verifying whether the first charge variation signal is indicative of the presence of the liquid on the main surface, at the first sensing electrode; and, if it is, determining the presence of the liquid on the main surface at the first sensing electrode.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： The present disclosure is directed to a device and method for detecting presence or absence of human speech. The device and method utilize a low-power accelerometer. The device and method generate an acceleration signal using the accelerometer, filter the acceleration signal with a band pass filter or a high pass filter, determine at least one calculation of the filtered acceleration signal, detect a presence or absence of a voice based on the at least one calculation, and output a detection signal that indicates the presence or absence of the voice. The device and method are well suited for portable audio devices, such as true wireless stereo headphones, that have a limited power supply.

摘要： 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.
