Abstract: A computing system (10) including: a first hardware element (12, 14), housing a first accelerometer (20; 22) and a first gyroscope (24; 26); a second hardware element (14; 12), housing a second accelerometer (22; 20) and a second gyroscope (26; 24), which can be oriented with respect to the first hardware element (12) and defines an angle (α LID ) with the first hardware element (12; 14); and a calculating unit (27, 28) configured for performing the operations of: calculating a first intermediate value (α LID_ACC ) of the angle (α LID ) on the basis of signals generated by the first and by the second accelerometers (20, 22); calculating a second intermediate value (α LID_GYR ) of the angle (α LID ) on the basis of signals generated by the first and by the second gyroscopes (24, 26); calculating a final value of the angle (α LID ) as the weighted sum of the first intermediate value (α LID_ACC ) and of the second intermediate value (α LID_GYR ); and controlling at least one parameter of the computing system (10) as a function of the final value of the angle (α LID ).

Abstract: A child safety seat (202) includes a motion sensor (214), e.g., an accelerometer, and a pressure sensor (116), e.g., an air pressure sensor. The motion sensor (114) is configured to detect a motion state of a vehicle (220) where the child safety seat is installed, e.g., whether the vehicle is moving or non-moving. The pressure sensor (116) is configured to detect a motion state of a door (222, 224) of the vehicle, e.g., a door open/close motion. Based on the information detected by the motion sensor and the pressure sensor, a controller (132) determines whether an awareness scenario occurs.

Abstract: 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.
