Three dimensional (3D) printer and rapid prototyping (RP) systems are currently used to quickly produce objects and to prototype parts using CAD tools. Most RP systems use an additive, layer-by-layer approach to building parts by joining liquid, powder, or sheet materials to form physical objects. Some of these RP systems through selective laser sintering amalgamate materials by heating them with lasers to generate 3D printed objects. Researchers at the University of California, Irvine have created a new 3D printer with improved selective laser sintering. The new 3D printer and process varies the composition of the materials in a 3D printed object thus creating an object with enhanced strength, conductivity, heat resistance and other enhancing properties.

University of California has invented a novel material and method for creating cost efficient seismic protection devices for all types of such structures.

The ability to accurately quantify gas volumes in liquid flows has important applications in environmental science and industry. For example, environmental processes that significantly contribute to changes in earth’s climate, such as methane seeps from the sea floor and the exchange of gases between the ocean and atmosphere at the sea surface, demand precise sensors that are small and sensitive enough to measure the ratio of liquids and gases in these bubbly mixtures. These measurements also play a critical role in the operational efficiency of a wide variety of different engineering processes. Applications include, the monitoring the optimal amount of bubbled oxygen in the treatment of waste water and sewage, and the oil and gas industry, especially in undersea oil pipelines in the Gulf of Mexico alone, have spent billions of dollars annually on added refinement techniques to remove seawater that could be preventable if sensors were able to measure the ratio of crude oil, seawater and gas as the mixture is pumped through pipelines. These challenges exist in both research and industry because the current manufacturing process for making the needed gas/liquid probes have significant cost constraints. Clearly, there is a need for a new and cost-effective technology to produce these probes.

Normally, charging a capacitive load from a voltage source invokes a ½ CV2 energy penalty. The concept of adiabatic charging, where the capacitor is charged more slowly than nominally afforded by the natural RC time constant of the charging circuit in the pursuit of reducing energy dissipation to below ½ CV2, has been around for decades. However, there has not been any solution to enabling this slow charging phenomenon in a practical, low-overhead embodiment. For example, prior work used separate DC-DC converters to provide multiple voltage levels, or used resonant inductors, both of which invoke significant area overhead.

Medical devices and wearable consumer products have fundamental anatomically-driven size constraints that necessitate small form factors. Since most patients and consumers desire long battery life, and battery volume is limited by anatomy, one of the only ways to increase lifetime is to reduce the power of the underlying circuits. The power consumption of wireless communication circuits is often large, and while power can be minimized by restricting the communication distance to just a few meters from sensor nodes to a personal base station as part of a body-area network (BAN), it can still dominate the overall energy budget of a wearable device. Current human body communication (HBC) systems communicate using capacitive electrodes that are placed on the body and generate electric fields that then have fringing currents that travel through conductive biological tissues (in one embodiment – galvanic coupling) or fringing fields that interact with the surrounding environment (in another embodiment – capacitive coupling). Both techniques have slightly better path loss than conventional far-field RF techniques, but suffer from electrode impedance variation, environmental variation, or both, making the design of ultra-low power HBC systems difficult. Establishing methods that improve path gain and thus reduced power consumption will aid the functionality of industry devices greatly.
