A method includes detecting touches on a touch-sensitive display of an electronic device, actuating an actuator to provide tactile feedback for the touches, determining values associated with force applied by the actuator during actuation of the actuator, and changing an attribute of actuation of the actuator based on the values associated with force.
摘要:
The disclosure describes a system and method for activating an electronic device from a low power state. The method comprises: monitoring a motion detection circuit for a signal indicating a movement of the device; analyzing the movement of the device and if the movement matches a profile for an activation movement for the device then activating a component on the device; and if the movement does not match the profile, then monitoring for additional movement signals for the device and providing data relating to the additional movement signals to a microprocessor in the device at an instance where the microprocessor is expected to be monitoring for receipt of a synchronization signal from a network in communication with the device is expected and when the instance is passed, the device is placed in second power operating mode, the second power operating mode consuming less power than the first power operating mode.
摘要:
Methods and apparatus employing non-magnetometer navigational sensor data to assist in determining whether a change in a magnetic field detected by a magnetometer is likely due to a source of internal or external magnetic interference, and more generally, whether such interference is likely to be persistent or transient. If the magnetic field data detected by the magnetometer indicates a large change in magnetic field, but the non-magnetometer navigational sensor (e.g., gyroscope) data does not indicate a corresponding change in orientation of the mobile device contemporaneous with the change in magnetic field, then the cause of the magnetic field change may be determined as likely originating from a localized external interference source and the device may prompt the user to move away from the interference source, rather than initiating a recalibration of the magnetometer.
摘要:
A system and method of obtaining magnetometer readings for performing a magnetometer calibration are provided. The method comprises detecting initiation of a magnetometer calibration; displaying a plurality of visual elements representing at least a pair of movements, each of the movements orienting a device comprising the magnetometer in substantially opposite positions along a respective axis; and obtaining at least one magnetometer reading during movement of the device. The visual elements may include one in an upright position, one in an upside down position, one facing a first direction and one illustrating the device facing in a second direction. A path may also be defined between the plurality of visual elements using one or more arrows.

摘要:
A method and system are provided for controlling an electronic device, such as a mobile device. The method comprises using a magnetometer of the electronic device to obtain a reading; determining whether one or more properties of the reading matches at least one magnetic signature from a set of magnetic signatures, each magnetic signature being indicative of an expected magnetic influence from another object; if the one or more properties match a particular magnetic signature from the set of magnetic signatures, determining one or more actions associated with the particular magnetic signature; and enabling the one or more actions to be performed using the electronic device.
摘要:
A cellular communications system may include a cellular base station and at least one mobile cellular device communicating with the cellular base station. The at least one mobile cellular device may include a receiver and a processor cooperating with the receiver for implementing a hybrid dynamic and static received signal measurement scheduling control. The processor may include a dynamic scheduler for scheduling recurring received signal measurement times, a static schedule memory for storing common data for received signal measurements, and a micro-scheduler for scheduling received signal measurements based upon the recurring received signal measurement times and the common data for received signal measurements.
