Mirror for Integrated Rehabilitation<br />

Stroke is a major cause of disability worldwide, often resulting in limited physical move- ments<br />
and impaired speech on one side of the body. Mirror therapy (MT) is a cost-effective technique<br />
that has been shown to aid in the restoration of hand mobility. However, for MT to be effective,<br />
patients must consistently practice a variety of exercises every day for a given amount of time.<br />
To help with this, we have developed a smart mirror using electro- luminescent (EL) technology.<br />
Our mirror utilizes a silver-doped conductive EL stack that emits monochromatic,<br />
non-dimensional light, easily observable from any angle. An opti- cal partially-transparent<br />
mirror is used to display exercise progress directly on the mirror, providing an integrated<br />
experience for patients. The display elements are powered by a fly- back converter adapted for<br />
high-voltage capacitor charging and controlled by a Raspberry Pi through level-transistors.<br />

8x8 MZI Beneš Switch Array Packaging and Testing<br />

Data centers across the US are expanding in order to meet growing demand for high performance<br />
computing. A large portion of power consumption results from the interconnects and switch<br />
relays that link servers to each other. In an effort to minimize the power lost in these regions of<br />
the data center, a solution must continue to deliver high bandwidth while simultaneously<br />
minimizing the energy requirements from the server. Our project revolves around one such<br />
solution that makes use of a purely optical interconnect which meets both bandwidth and power<br />
requirements for the data centers of the future. We integrate a 8x8 Mach-Zehnder Interferometer<br />
Beneš Switch Array implemented as a photonic integrated circuit (PIC), into an electronics<br />
packaging and test bed environment such that its features may be tested within experimental and<br />
practical data centers.<br />
