Abstract: 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.

Abstract: A computing system includes a first hardware element having a first accelerometer and a first gyroscope, and a second hardware element having a second accelerometer and a second gyroscope. The first and second hardware elements are moveable with respect to each other. The computing system recursively generates a result signal indicative of a relative orientation of the first and second hardware elements with respect to each other. The result signal may be generated by generating a first intermediate signal indicative of a angle between the first and second hardware elements based on signals generated by the first and second accelerometers and generating a second intermediate signal indicative of the angle based on signals generated by the first and second gyroscopes. The result signal indicative of the angle may be generated as a weighted sum of the first intermediate signal and the second intermediate signal. At least one of the first and second hardware elements is controlled by on the result signal.

Abstract: An embodiment pointing method to generate screen-frame displacement data based on 3D-space movements of a pointing electronic device, comprises receiving a gravity vector (g), having components (gx, gy, gz) corresponding to respective projections of gravity acceleration ({right arrow over (g)}) on three axes (X, Y, Z) of a 3D reference system associated with the pointing electronic device, generated by a sensor-fusion algorithm from joint processing of an acceleration signal, indicative of acceleration acting on the pointing electronic device along the three axes, and of a gyroscope signal (Gyro), indicative of angular rate of rotation of the pointing electronic device around the three axes. The method further comprises implementing a roll-compensation of the gyroscope signal (Gyro) as a function of the gravity vector (g) to determine a roll-compensated gyroscope signal (Gyro′); and generating the screen-frame displacement data based on the roll-compensated gyroscope signal (Gyro′).

Abstract: A system recognizes a gesture of bringing a mobile electronic device to a user ear. The system may be integrated in the mobile electronic device and is provided with a movement sensor which provides a movement signal indicative of the movement of the mobile electronic device. A pressure sensor provides a pressure signal indicative of a pressure acting on the mobile electronic device during the movement. A processing stage performs a joint processing of the movement signal and of the pressure signal in order to recognize the gesture.

Abstract: An activity tracking device, such as a step-counting device includes an interface configured to receive one or more acceleration signals and signal processing circuitry. The signal processing circuitry generates an indication of condition of an accelerometer, such as a body position of the accelerometer, based on one or more accelerometer signals, generates an event signal, such as an event flag, based on one or more accelerometer signals and the indication of the condition of the accelerometer, and generates an activity signal, such as step flag based on the event signal, the indication of the condition of the accelerometer and one or more acceleration signals. The signal processing circuitry may generate a noise signal based on one or more acceleration signals and generate the activity signal based on the noise signal.

Abstract: A method includes receiving electrostatic sensor data in a processor of an electronic device from an electrostatic sensor mounted behind a touchscreen of the electronic device and using the electrostatic sensor data to determine when the touchscreen is being used. Based on whether or not the touchscreen is being used, an on-table detection (OTD) algorithm is selected from a plurality of available OTD algorithms. In one or more examples, the OTD algorithm may also be selected based on the current device mode of the electronic device, which may be determined from a lid angle, a screen angle, and a keyboard angle of the electronic device. The selected OTD algorithm is run to determine whether or not the electronic device is located on a stationary or stable surface.
