Abstract: A pulse shaping device includes an inductor that is selectively output-coupled to a first port of a capacitor. The inductor is charged to a selected current throughput and then coupled to the first port to generate a first characteristic within the current flowing at a second port of the capacitor. The capacitor is charged until reaching a clamping voltage at the first port. A voltage clamp of the shaping device clamps the first port of the capacitor at the clamping voltage to generate a second characteristic within the current flowing at a second port of the capacitor.

Abstract: The increased use of graph algorithms in diverse fields has highlighted their inefficiencies in current chip-multiprocessor (CMP) architectures, primarily due to their seemingly random-access patterns to off-chip memory. Here, a novel computer memory architecture is proposed that processes operations on vertex data in on-chip memory and off-chip memory. The hybrid computer memory architecture utilizes a vertex's degree as a proxy to determine whether to process related operations in on-memory or off-chip memory. The proposed computer memory architecture manages to provide up to 4.0× improvement in performance and 3.8× in energy benefits, compared to a baseline CMP, and up to a 2.0× performance boost over state-of-the-art specialized solutions.

Abstract: Pervasive and interactive displays promise to present digital content seamlessly throughout a room. However, traditional display technologies do not scale to room-wide applications due to high per-unit-area costs and the need for constant wired power and data infrastructure. This disclosure proposes the use of photochromic paint as a display medium. Applying the paint to any surface or object creates ultra-low-cost displays, which can change color when exposed to specific wavelengths of light. New paint formulations are developed that enable wide area application of photochromic material. Along with a specially modified wide-area laser projector and depth camera that can draw custom images and create on-demand, room-wide user interfaces on photochromic enabled surfaces. System parameters such as light intensity, material activation time, and user readability are examined to optimize the display. Results show that images and user interfaces can last up to 16 minutes and can be updated indefinitely.

Abstract: Various methods of manufacture can produce three-dimensional, high density, high-electrode probe arrays that can advantageously be used in neural-based applications. In one example, deep reactive ion etched (DRIE) ultra-high aspect ratio holes are etched in silicon and refilled with multiple films to a high density array of individual probes, each probe having individual recording and/or stimulation sites or tips. Using a DRIE lag effect technique can help control tip sharpness and electrode length, allowing for narrow, long, and dense needles to be formed side-by-side in a single array. In some examples, multimodal probe arrays are manufactured, with some probes having a recording/stimulating site, other probes having a waveguide, and yet other probes having a microfluidic channel.
