Abstract: A method for the delivery of power to subthreshold (sub-Vt) circuits uses unused current during idle-mode operation of super-threshold (super-Vt) circuits is used to supply sub-Vt circuits. Algorithmic and circuit techniques use dynamic management of idle cores when reusing the leakage current of the idle cores. A scheduling algorithm, longest idle time-leakage reuse (LIT-LR) enables energy efficient reuse of leakage current, which generates a supply voltage of 340 mV with less than ±3% variation across the tt, ff, and ss process corners. The LIT-LR algorithm reduces the energy consumption of the switch and the peak power consumption by, respectively, 25% and 7.4% as compared to random assignment of idle cores for leakage reuse. Second, a usage ranking based algorithm, longest idle time-simultaneous leakage reuse and power gating (LIT-LRPG) enables simultaneous implementation of power gating (PG) and leakage reuse in a multiprocessor system-on-chip (MPSoC) platform.

Abstract: An approach is described for enhancing the security of analog circuits using Satisfiability Modulo Theory (SMT) based design space exploration. The technique takes as inputs generic circuit equations and performance constraints and, by exhaustively exploring the design space, outputs transistor sizes that satisfy the given constraints. The analog satisfiability (aSAT) methodology is applied to parameter biasing obfuscation, where the width of a transistor is obfuscated to mask circuit properties, while also limiting the number of keys that produce the target performance requirements.

Abstract: Low latency beamforming using phased antenna arrays is the key for practical deployment of envisioned millimeter wave (mmWave) Gbps mobile networks. This work aims towards reducing the overhead of the exhaustive sector-level sweep phase of the analog beamforming adopted in the IEEE 802.11ad standard. This system uses a reconfigurable antenna single RF chain in the sub-6 GHz new radio (NR) band to aid codebook-based beam selection in the mmWave band of the NR. The system exploits the congruence between the spatial propagation signatures of signals at both mmWave and sub-6 GHz frequencies to reduce the beam search space.

Abstract: An inventive approach is disclosed to integrate Digital Image Correlation (DIC) with the Acoustic Emission method that may be used for structural health monitoring and assessment of critical structural components in civil, mechanical, and aerospace industries. The inventive approach relies on passively recording acoustic emission across the specimen being tested and activating the DIC cameras automatically to measure deformation on the specimen's surface. The resulting acousto-optic system can be used to determine damage initiation, progressive damage development, identify critical regions and make lifetime predictions of the tested specimen.

Abstract: The present invention provides a 4D printed component that uses the photoisomerization stimulus as a method of activation. Other 4D printing methods use heat, moisture, a combination of heat and stress, and the heat from a light source as methods of activation.

The invention reduces the number of required 3D printed parts to create a moving object. This characteristic reduces the amount of onboard weight of the 3D printed components by reducing the number of parts required to create motion. The present invention removes the need for onboard sensors, processors, motors, power storage, etc. This characteristic will allow for manufacturing of, inter alia, novel medical devices, automated actuators, packaging, smart textiles, etc.

Abstract: An on-chip voltage delivery method for a system includes multiple processor cores operating at multiple voltage levels. Distributed on-chip DC-DC converters as voltage regulators may deliver point of load current to the different units of a processor core operating at the same voltage level. Distributed timing sensors calibrated to generate digitized clock edge location. A power management unit may take input from the timing sensors, processes it through a particle swarm optimizer and generates digitized voltage identification code as reference to the distributed voltage regulators. The particle swarm optimizer may provide disparate voltage levels feasible for a given frequency of operation of the processor core with a provision to operate at multiple frequencies. The run-time assignment of the voltage through the particle swarm optimizer may negate the effects of transistor aging, process, temperature, and power supply noise induced variation in the load circuits, voltage regulators and sensors.
