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: 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: The device (10) has enhanced human activity recognition. The device comprises a processing unit (16) configured to detect a human activity using one more motion sensors (12), and enhances the detected human activity depending on whether the device is in an indoor environment or an outdoor environment. The processing unit (16) utilizes one or more electrostatic charge sensors (14) so as to determine whether the device is in an indoor environment or an outdoor environment.
