Abstract: An inertial measurement system (1), having: at least one motion sensor (2) to output motion data with an output data rate - ODR -period (T ODR ); and a control unit (4) coupled to the motion sensor (2) to control operation thereof based on a power mode switching, according to which each ODR period (T ODR ) envisages: a first phase (T OFF ), in which the motion sensor (2) is controlled in a condition of low power consumption; and a subsequent measurement phase (T MEAS ), in which the motion sensor (2) is controlled to perform measurements for generation of measurement data. The control unit (4) adaptively adjusts the duration of the ODR period (T ODR ) based on at least one check related to the measurement data generated during the measurement phase.

Abstract: A remote access device (200) and method of operation thereof are provided for accessing a physical object or location. The remote access device includes an accelerometer (204), a wireless transmitter (206), and control circuitry (202). The control circuitry (202) causes the wireless transmitter (206) to transition between a first operating mode (108) and a second operating mode (110) in response to receiving signals from the accelerometer (204) indicating a first change in motion states of the remote access device. The control circuitry (202) causes the wireless transmitter (206) to transition between the first operating mode (108) and the second operating mode (108) in response to receiving signals from the accelerometer (204) indicating a second change in motion states of the remote access device. The control circuitry (202) further causes the wireless transmitter (206) to transition between the first operating mode (108) and the second operating mode (110) in response to receiving signals from the accelerometer 104 indicating a third change in motion states of the remote access device.

Abstract: A method for controlling an electronic apparatus (10) on the basis of a value of a lid angle (α LID ) between a first hardware element (12) accommodating a first magnetometer (20) and a second hardware element (14) accommodating a second magnetometer (22), comprising: acquiring, through the magnetometers, first signals (B 1 , B 2 ) representing an orientation of the hardware elements; generating, on the basis of the first signals, a calibration parameter (J 1 ) indicative of a condition of calibration of the magnetometers; generating, on the basis of the first signals, a reliability value (K 1 ) indicative of a condition of reliability of the first signals; calculating (50) a first intermediate value (α LID_MAG ) of the lid angle (α LID ) on the basis of the first signals; calculating (53) a current value of the lid angle (α LID ) on the basis of the calibration parameter (J 1 ), of the reliability value (K 1 ) , and of the first intermediate value (α LID_MAG ) ; and controlling the electronic apparatus on the basis of the current value.

Abstract: The system (1) for detecting and evaluating environmental quantities and events is formed by a device (2) and a mobile phone (3), connected together through a Bluetooth connection (4). The device (2) is enclosed in a containment casing (10) housing a support (20) carrying a plurality of inertial sensors (35) and environmental sensors (36); a processing unit (39), coupled to the inertial sensors and to the environmental sensors; a wireless connection unit (38), coupled to the processing unit; a wired connection port (26), coupled to the processing unit; programming connectors (30), coupled to the processing unit (39) and configured to couple to an external programming unit to receive programming instructions of the processing unit; a storage structure (33), coupled to the processing unit; and a power-supply unit (41). The mobile phone (3) stores an application, which enables a basic use mode, an expert use mode, and an advanced use mode.
