    Abstract: Detection method (50) of a first or second state of a foldable electronic device (10) comprising a first and a second hardware element (12; 14) tiltable to each other and accommodating a first and a second electrode (20b; 22b) 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 (50) is performed by a control unit (23) of the foldable electronic device and comprises the steps of: acquiring (S10) a first and a second charge variation signal indicative of environmental electric/electrostatic charge variations detected by the first and second electrodes; generating (S12) a differential signal (S D ) indicative of a difference between the first (S Q1 ) and the second (S Q2 ) charge variation signals; generating (S14, S16, S18, S20), as a function of the differential signal (S D ), one or more feature signals (S T ); and generating (S22), as a function of the one or more feature signals (S T ), a contact signal (Sc) indicative of the first or second states of the foldable electronic device (10) .

    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 pointing method to generate screen-frame displacement data based on 3D-space movements of a pointing electronic device (1), envisages: receiving attitude quaternion data (q), indicative of an orientation of the electronic device (1) in the 3D-space, generated by a sensor-fusion algorithm from joint processing of an acceleration signal (Acc), indicative of acceleration acting on the pointing electronic device (1) along three reference axes (X, Y, Z) of the 3D-space, and of a gyroscope signal (Gyro), indicative of angular rate of rotation of the pointing electronic device (1) around the three reference axes (X, Y, Z) of the 3D-space; processing the quaternion data (q) to determine an orientation difference between a current orientation and a previous orientation of the electronic device (1) in the 3D-space; translating the orientation difference from the quaternion space to tilt-compensated angular rate of rotation (g x , g y , g z ) of the electronic device (1) in the 3D-space; and generating the screen-frame displacements based on the tilt-compensated angular rate of rotation in the 3D-space.

    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 gesture-recognition system for a digital-pen-like device (1), envisages: at least one motion sensor (2) to provide at least one motion signal (Sm) indicative of movements of the digital-pen-like device (1); a gesture-recognition module (6), coupled to the at least one motion sensor (2) to process the motion signal (Sm) and to implement a plurality of gesture recognition algorithms based on the motion signal (Sm), each of the gesture recognition algorithms being configured to recognize a corresponding gesture performed by a user of the digital-pen-like device (1); and a control unit (8) coupled to the gesture-recognition module (6) and transmitting gesture-recognition data indicative of a recognized gesture towards a host apparatus (10), with which the digital-pen-like device (1) is associated.
