Abstract

In one example a sensor module comprises at least one sensor and a controller communicatively coupled to the at least one sensor by a communication bus, the controller comprising logic, at least partially including hardware logic, configured to generate a signal to configure the at least one sensor in a notify power state mode and place the signal on a communication bus coupled to the at least one sensor. Other examples may be described.

generate a signal to configure at least one sensor for an electronic device in a notify power state mode; and

place the signal on a communication bus coupled to the at least one sensor; and

transmit at least one feedback parameter to the at least one sensor, wherein the feedback parameter is used to adjust an input from the at least one sensor on the communication bus, wherein the feedback parameter is used to decrease a weight of an accelerometer input to the communication bus in response to an increase in an output of the accelerometer.

2. The controller of claim 1, further comprising logic, at least partially including hardware logic, configured to:

generate a signal to configure an interrupt priority in the at least one sensor; and

place the signal on a communication bus coupled to the at least one sensor.

3. The controller of claim 2, further comprising logic, at least partially including hardware logic, configured to:

detect a change in an environmental condition; and

change the interrupt priority of the at least one sensor in response to the change in the environmental condition.

4. The controller of claim 1, further comprising logic, at least partially including hardware logic, configured to:

receive a power state notifier signal from the at least one sensor, wherein the power state notifier signal identifies a power state of the at least one sensor; and

record the power state of the at least one sensor in a memory.

17. The controller of claim 1, wherein the feedback parameter is used to decrease a weight of a magnetometer input to the communication bus in response to an increase in an output of the magnetometer.

18. The controller of claim 1, wherein the feedback parameter is used to decrease a weight of a gyroscope input to the communication bus in response to a location algorithm converging.

19. The controller of claim 2, further comprising logic, at least partially including hardware logic, configured to:

set the interrupt priority of an accelerometer to an initial value during a configuration process; and

increase the interrupt priority in response to a determination that the electronic device is in motion.

5. A sensor module, comprising:

at least one sensor; and

a controller communicatively coupled to the at least one sensor by a communication bus, the controller comprising logic, at least partially including hardware logic, configured to;
