Researchers at UCLA have developed a solution-based processing method to produce Cu-In-S ternary nanocrystals with tunable material characteristics that are suitable for use in high efficiency solar cell fabrication.
The researchers have developed a method to produce colloids of the ternary nanocrystal Cu-In-S through an all-solution process. This technique allows control over the composition ratio and the ability to determine the crystalline structure, which was previously unattainable with colloidal syntheses of these materials. In addition, the bandgaps of the materials have tunable absorption from visible through to IR wavelengths. The invention enables low-cost fabrication of inorganic photovoltaics as well as the printing and patterning of nanowires. MORE [2008-608]

Researchers at UCLA have developed a comprehensive teleconsultation system that enables physicians secure access to patient data by utilizing cutting edge technology and a multitasking operating system. The system supports both voice and data simultaneously, and from the first time a patient registers at a facility to post-care questions after release, it captures and organizes patient data. The system continuously compiles and instantaneously broadcasts secure and customizable records containing patient identity, health care summary, lab results, images, procedures and diagnoses to the attending physician's device. This teleconsulting system allows for thorough and timely care and increased patient satisfaction. MORE[2007-479]

UCLA investigators, from the Department of Chemical and Biomolecular Engineering, have engineered a synthetic pathway within E. coli to produce high quantities of both acetone and isopropanol. The amount of isopropanol produced exceeds that from native producers.
UCLA researchers have engineered a synthetic pathway into E. coli to produce isopropanol. This is the first time researchers have used E. coli to produce isopropanol, and the amount produced exceeded that from native producers. Researchers assembled the best combination of genes based on the C. beijerinckii pathway to produce acetone through E. coli. Acetone is then converted to isopropanol using acetyl-coenzyme A (acetyl-CoA). Using this engineered strain of E. coli, 81.6 mM of isopropanol has been produced in shake flasks. MORE [2008-177]

UCLA researchers in the Department of Electrical Engineering have developed a fast, stable computer-aided design (CAD) algorithm to model large-scale RLC networks with inductance.
The RLC networks are conventionally modeled and simulated using software akin to SPICE, but which are typically slow for such high-capacity systems. For this reason, constructing a representative macromodel is often done, though current approaches cannot manage large-scale inductances. This invention establishes a fast and stable macromodeling algorithm which can effectively account for on/off-chip power delivery and sparse EM coupling with inductance. Its order-reduction methodology decreases runtime by allowing efficient parallelization with simulation.
This invention can also be adapted to a micro-electro-mechanical systems (MEMS) environment to provide similar modeling advantages. MORE [2008-304]

A pneumatic haptic feedback system has been designed to be modular, scalable and miniaturized. When the operator applies a force upon an object to be manipulated, a sensor transmits a signal that results in the application of proportional pressure upon the hands of the operator. In addition, a control system has been engineered to regulate the signal input in proportion to the applied force. The adaptability of this system allows for straightforward custom redesigns and lower system integration expenses. In addition, this system has been constructed for wireless applications.

Researchers at UCLA have identified an algorithm that monitors and analyzes the picture quality of broadcast cable television. Installed on a modified computer with a TV tuner and database system, the TV tuner acquires JPEG images of channels for the algorithm to analyze for quality. After saving these images to the database and determining the quality of the picture, the algorithm is then able to allow the administrator to access the data through a web-service code to effectively monitor picture quality.

UCLA scientists have discovered a new route for systematically designing and directing the assembly of custom-shaped particles by tailoring the surface roughness of custom-shaped microparticles.
Researchers at UCLA have studied dispersions of microscopic particles mixed with depletion agents and demonstrated that the strength of depletion attractions between the different surfaces of the particles can be tuned not only through shape control, but also through localized control of the surface roughness. This is another viable route for systematically designing and directing the assembly of custom-shaped particles by tailoring the surface roughness of custom-shaped microparticles dispersed in a liquid and varying the size of smaller nanoscale colloids relative to the roughness. Commercial applications include mass producing microscale devices made from several interlocking pieces, including microscale engines and pumps. In addition, particles can be aggregated and separated based on surface roughness to remove particles with very rough surfaces. Other applications include decorating surfaces with particles, depending on the roughness of the particles.

Researchers at UCLA have developed an efficient computation procedure for exact gradient computation for a wide range of global smoothing techniques used in density-constrained analytical placers. The exact computation of the gradient of these smoothing functions was not available in the past, and only heuristic approximation was used, which may lead to inferior placement solutions. The invention is considered a significant breakthrough in analytical placement as it enables the density-constrained placement problems with global smoothing technique to be solved exactly in the general nonlinear programming framework.

UCLA researchers in the Department of Computer Science have developed an invention to quantify how much a piece of personal information can be inferred based on social network structures revealed in online social networking services and methods to automatically generate recommendations to protect such personal information.
Recent years have seen a huge growth in online social networking sites such as Facebook, Myspace, and Friendster. Given the huge amount of personal data and social relationships available in online social networks, protecting one's personal privacy is a growing problem. Since private information can be inferred via social relationships, it is possible to infer private information even when such information is not shared.
The invention uses a method to infer with a high degree of accuracy personal information based on social networks. MORE [2007-626]
