A final consideration for sampling patterns is to wake the sensor for a burst of measurements. In cases where the system response remains constant for a longer duration, it can be possible to keep the device in a low power state when not needed to conserve power. At some desired interval, the device can be brought out of low power sleep mode, allowed to calculate δθ/δt for n samples, and then return to sleep. This method maintains the benefit of a running average calculation, but only provides periodic updates. Running calculations at wider intervals is desirable to achieve lower power consumption for functions that do not require continuous updates.
