A MEMS (Microelectromechanical System) INU (Inertial Navigation Unit) chip comprises a compact autonomous device undergoing motion tracks and analyzes its definite movement relative to local Earth coordinates with optimal accuracy and repeatability of lmm over distances of greater than two meters. The MEMS INU includes an Inertial Motion Tracking Device (IMTD) comprises a gyroscope, accelerometer, magnetometer, and digital processor programmed with a general purpose Inertial Measurement Engine (IME), an application specific Motion Analysis and Adaptation (MAA) program and a low power radio. The IMTD tracks its motion with optimum accuracy using compact practical sensors that may have noise and drift by periodically and autonomously checking its velocity changes at an optimum interval, computing a linear acceleration therefrom and determining a no-motion or motion condition relative to a threshold and correcting its velocity, position and acceleration errors when there is no motion.

The disclosure provides for a method for identifying and measuring a signal pulse induced in a microcircuit due to ionizing radiation. The method comprises locating an ionizing radiation induced pulse across a microcircuit using a plurality of sensors on the microcircuit. The method further comprises radiating a radiation through the microcircuit to produce a pulse width. The method further comprises using a time to digital converter (TDC) to measure a duration of the pulse width to create a measured pulse width. The method further comprises using the TDC to convert the measured pulse width into a digital signal.
