Existing high-channel-count interfaces used to capture neural information from and to stimulate neural activity in tissues rely on transcutaneous connections to convey both information and power. These transcutaneous connections introduce a number of significant problems: limit patient comfort/mobility, increase infection risk, and significantly reduce the long-term system reliability. In this Pha ...

This project aggregates, adapts and leverages the optimum technology for each function in a heterogeneously integrated power stage (HIPS) for package-integrated voltage regulators (PIVRs):Gallium arsenide (GaAs) die - monolithically integrate multiple lateral field effect transistors (FETs) using a high-volume foundry. Sardas technology reduces the GaAs cost by >80% by reducing the die size and en ...

Insuring the safety and control of littoral waters is problematic because of the difficulties of surveillance. The preferred methods of surveillance in the ocean are acoustic. In littoral waters, acoustic methods fail because noise from the surf and reflections from the shallow bottom convolute acoustic signatures beyond our capacity to discern them. Water absorbs light, reducing the effectiven ...

In phase I, Dot Metrics Technologies demonstrated the feasibility of a new method of introducing deep-green luminescent nanostructure into semiconductor materials for light-emitting device applications. The materials were used to fabricate and characterize preliminary optoelectronic device test structures. In phase II, Dot Metrics Technologies proposes to leverage these new materials and methods i ...

Power generation, power distribution and electric propulsion on ships and aerospace vehicles could be made smaller, lighter, more efficient, more versatile, and lower maintenance by operating these systems—partly or entirely—at cryogenic temperatures. Our goal is to demonstrate the advantages of cryogenic operation in regard to electronic components, specifically semiconductor devices (power d ...

The benefits of greater power and efficiency are offered by using turbochargers and superchargers for small UAS propulsion systems which including rotary, piston, and other developing engines. Present day UASs suffer performance losses upon takeoff and at altitude. Therefore, the need for improved, light weight turbo and superchargers which eliminate the use of oil lubrication for the bearing sy ...
