20170397 – The Vision-aided Inertial Navigation Systems (VINS) algorithm uses visual and inertial data for tracking in real time the 3D position and attitude of an IMU-camera pair. Please visit the Multiple Autonomous Robotic Systems laboratory website for more information.
20130335 – A new modular multilevel converter (MMC) can reach twice the voltage levels as conventional electrical energy transmission topologies. The modular structure of this MMC enables it to reach three voltage levels by adding a bidirectional switch with half the voltage stress, resulting in low switching frequency and near sinusoidal voltage waveforms. Benefits of these submodule topologies... Read More
20150060-1 – A novel AC homopolar motor topology is extremely efficient, and with minimal maintenance required, it drives down operating costs. The motor comes with an optional outer-rotor/inner-stator, as well as a single set of windings that provide both torque and magnetic suspension without using rare-earth permanent magnets or a separate set of armature coils. The design enables a predictive,... Read More
20170355 – A dual-incentive peer mentoring model, Positive Peer-Pressured Productivity (PQUAD), shows promising results in increasing academic productivity of early-career faculty. PQUAD combines an increased awareness of peers’ academic work with a weighted lottery for which tickets are earned on the basis of academic output. The incentive program assigns points for different scholarly activities... Read More
20150366 – This low-cost, model-based simulation software with hardware integration for real-time controller implementation allows users to model electro-mechanical prototype devices. This solution provides both simple and complex control algorithms that users with no prior knowledge of programming or microcontrollers can easily implement. The hardware controller is built around TI Delfino... Read More
20170093 – A search coil based frequency mixing method characterizes both magnetic and physical properties of superparamagnetic iron oxide nanoparticles (SPIONs). The technology analyzes the harmonic ratios and phase lags from liquid and frozen SPION samples to distinguish between single- and multi-core SPIONs. It also predicts saturation magnetization, average hydrodynamic size and dominating... Read More
20160317 – A new algorithm solves the ubiquitous optimal power flow problem for distribution networks—in real-time. This method develops distributed feedback controllers that continuously drive inverter output powers to solve AC optimal power flow (OPF) problems. The controllers update power set points based on voltage measurements as well as given (time-varying) OPF targets, and implement solutions... Read More
20110144 – A new architecture for organic photodetectors uses multiple layers to provide a tunable response specific to the wavelength of interest. The single-device design, which uses multiple organic photodetector subcells in a stacked/tandem architecture, uses organic semiconductors with complementary optical absorption for broadband optical response. The device permits a tunable spectral... Read More
z04142 – A particle-detecting integrated circuit that contains a device with a pair of conductive lines positioned in a vacuum environment can detect particles in real time in a semiconductor vacuum environment. The conductive lines are spaced at a critical pitch corresponding to diameters of particles of interest. An impedance measurement system linked to the circuit detects a change in an... Read More
20160097 – A newly discovered xylose operon converts xylose from lignocellulosic biomass into TCA compounds, which can then be further converted to 1,4-butanediol (BDO). A new synthetic pathway in E. coli produces 1,4-butanediol in only six steps, making it more efficient than previous pathways used in current industrial methods (which require 20 steps). The technology combines previous pathways,... Read More
