    Abstract: a) A Gabor domain optical coherence microscopy (GD-OCM) system providing high resolution of structural and motion imaging of objects such as tissues is combined with the use of reverberant shear wave fields (RevSW) or longitudinal shear waves (LSW) and two novel mechanical excitation sources: a coaxial coverslip excitation (CCE) and a multiple pronged excitation (MPE) sources providing structured and controlled mechanical excitation in tissues and leading to accurate derivation of elastographic properties. Alternatively, general optical computed tomography (OCT) is combined with RevSW or LWC in the object to derive elastographic properties. The embodiments include (a) GD-OCM with RevSW; (b) GD-OCM with LSW; (c) General OCT with RevSW; and General OCT with LSW.

    Abstract: A hybrid integrated thermal sensor device includes a magnetic tunnel junction (MTJ) device electrically coupled in series with at least one CMOS transistor and disposed between a voltage rail terminal and a ground terminal. An output terminal is electrically coupled to a drain of the at least one CMOS transistor. The MTJ operates in an anti-parallel state and the output terminal provides a voltage indicative of a temperature of the MTJ device based on an MTJ antiparallel resistance. A distributed sensor network for real-time thermal mapping of an integrated circuit (IC) is also described.
