摘要： A device having a sensor may be calibrated by obtaining a condition of a device incorporating the sensor and initiating a calibration operation for the sensor based, at least in part, on the condition of the device. The condition may be a motion state, a charging state, a pattern of motion, an orientation, a location, a surrounding environment measurement, sensor usage, an age of calibration, a quality of calibration, or any combination. Further, the sensor may be an accelerometer, a gyroscope, a magnetometer or a pressure sensor.

摘要： Systems and methods are disclosed for deriving linear acceleration using an accelerometer. The orientation of a device may be determined using only accelerometer data. The determined orientation may then be used to determine a gravity vector, such that linear acceleration may be derived by subtracting the gravity vector from accelerometer data.

摘要： Systems and methods are disclosed for providing sensor data to a host processor. A sequence of data samples may be generated at a sample rate established by a clock source associated with the sensor. A time stamp derived from another clock source, such as the clock employed by the host processor, is assigned to at least one of each periodically retrieved data samples. As such, at least one of the assigned time stamps then may be adjusted by applying a correction determined from a timing characteristic associated with retrieval of the data samples.

摘要： Systems and methods are disclosed for detecting when a magnetic anomaly may impact the quality of data being output by a magnetometer. A plurality of detection algorithms may be performed in parallel on the sensor data. Further, indication of a anomaly from one or a combination of the detection algorithms may cause the magnetometer data to have a reduced contribution in any sensor fusion operation or may be omitted from a sensor fusion operation as desired.

摘要： A state machine may be implemented in hardware by representing each state with one operational code (opcode) such that each opcode may be read from memory in sequential order. The state machine includes a plurality of states linked by at least one transition triggered by data input. The data input may be motion sensor data such that the state machine is configured to recognize a pattern of motion corresponding to a gesture or an activity.
