The inventors at UCI have made many antennas accessible by interleaving the training and feedback stages.

Lockout Tagout Software

Energy Isolation Lock out Tag out (“LOTO”) is a series of CalOSHA and FedOSHA code compliance requirements and is the primary means by which equipment must be rendered “safe” prior to allowing personnel to work on the equipment.  LOTO codes require equipment-specific written procedures identifying all types of energy sources needed to operate the equipment as well as the energy-isolation methods and locations of utility disconnects, stored energy, etc. In addition, every LOTO procedure must be annually verified to confirm the written procedure is still accurate to the equipment.   Whereas current LOTO procedures are typically hand-written or using other time-consuming processes, UC Berkeley authors have created software allowing users to retrieve LOTO procedures in real-time guiding the end-user through a logical thought process to allow them to identify all energy sources and safety processes, and equipment needed.

Enhanced Patterning Of Integrated Circuits

Information and communication technologies rely on integrated circuits (ICs) or “chips.” Increased integration has improved system performance and energy efficiency, and lowered the manufacturing cost per component. Moore’s Law predicts that the number of transistors on an IC will double every two years, yet industry experts predict that we are reaching economic limits of traditional circuit patterning processes. Photolithographic patterning is best suited to print linear features that are evenly spaced. The smaller or more complex the shape, the more likely the printed pattern will be blurred and unusable. Although multiple-patterning techniques can be used to increase feature density on ICs, they bring a high additional cost to the process. This means that the most advanced ICs available today have a high density of features, but are restricted to having simple patterns and are increasingly expensive to produce. Without innovations in production techniques, Moore’s Law will reach its end in the near future.  To address this issue, researchers at UC Berkeley have developed a one-step method to increase feature density on chips. This method is capable of achieving arbitrarily small feature size, and self-aligns to pre-existing features on the surface formed by other techniques. 

A Robust Hybrid Control Algorithm for a Single-Phase DC/AC Inverter

Along with fossil and nuclear-based power, future energy distribution systems ought to be capable of interconnecting diverse renewable sources, such as hydroelectric generators, photovoltaic arrays, and wind turbines, as well as energy storage systems. The development of “Smart Grid” is needed due to increasing electricity demands and the need regulate input power sources. However, a particular challenge anticipated by a “Smart Grid” is the high variability of the power provided by the renewable sources, mainly due to their high dependence on environmental conditions. In turn this variability imposes a challenge to power conversion in particular, between DC and AC signals. Single-phase DC/AC inverter, using Pulse Width Modulation (PWM) is one of the most common topologies used in power conversion. However, one of the main shortcomings of converters controlled by PWM-based algorithms is that they are not robust to changes in the input DC voltage, which limits their use in renewable energy applications.

Methods And Means For Rapidly Detecting And Locating Faults In Overhead Electrical Power Lines And Providing For The Immediate Removal Of Hazards...

Failures in the distribution systems are brought to the attention of the utility service provider by the call of the customer, even with the advent of the smart meter. This is also the case in a downed power line; wherein, it is the customer who first reports the problem to the utility company. The typical response of the utility provider is to dispatch emergency personnel to the locale to manually disconnect / de-energize the line.  In some cases, it requires emergency personnel to search for and identifying the probable cause. Understandably there is significant hazard to life and property due to down utility lines. While protective equipment in power distribution systems protect against high current faults, they do not adequately protect the public or environment when a line falls to the ground. These high impedance faults do not draw enough current to cause protective relays to open, leaving the line energized and dangerous. The development of a future smart grid and other intelligence in the distribution system, and the corresponding explosion of potentially available real-time measurements, suggest even more significant opportunities for improvement.

Fractal RF Coils for Use in High Field MRI (>3T) Resulting in High Resolution Images

Researchers at the University of California, Irvine have designed a fractal shaped RF coil for magnetic resonance (MR) image acquisition that effectively reduces interference commonly associated with coil loops (such as the birdcage coil) that are in close proximity. Limiting coil interference enables an increase in the flexibility of phased array design and reduces the need for additional system components to cancel out signal noise.
