Abstract
Systems and methods are provided for improved multifunction sensing. In these embodiments a multifunction sensing device (100) includes a microelectromechanical (MEMS) gyroscope (110) and at least a second sensor (112). The MEMS gyroscope (110) is configured to generate a first clock signal, and the second sensor includes a second clock signal. The multifunction sensing device further includes a reset mechanism (114), the reset mechanism (114) configured to generate a reset signal to set the relative periodic phase alignment of the second clock signal to the first clock signal. Consistently setting the relative periodic phase alignment of the clocks for the other sensor devices (112) to the clock of the MEMS gyroscope (110) can improve the performance of the devices by reducing the probability that varying output offsets will occur in the multiple sensing devices.
