FEATURED TECHNOLOGY

Highly Accurate Radio Chip Localization Technology

Summary: This technology, developed at Vanderbilt University's Institute for Software Integrated Systems, uses radio interferometry to locate tangible objects and attains, simultaneously, a higher degree of accuracy (within 3 centimeters), considerably longer range (up to 160 meters) and lower cost than other technologies.
FEATURED TECHNOLOGY

Brain Shift Compensation Using Computer Models

This technology eliminates the need to place cortical fiducial markers during image guided neurosurgery. As an additional and important feature, the technology is able to compensate for brain shift due to deformation of the brain during surgery.

Transcend: Qualitative Diagnosis System & Method

Transcend is a model-based diagnosis system for fault detection and isolation of abrupt faults in complex to very complex engineered systems. It applies models of dynamic system behavior to obtain accurate predictions for measured transients and compares predictions with actual observations to distill the true cause for the faulty behavior. To successfully perform diagnosis, Transcend needs a dynamic model of the system.

Direct Laser and Ultraviolet Lithography of Porous Silicon Photonic Crystal Devices

We have developed a technique to process photolithographically porous silicon heterostructures and photonic crystal architectures, using laser and ultraviolet light exposure and a subsequent alcoholic bath treatment. This technique would be the first method to process directly the optical properties of porous silicon multilayers, heterostructures, and photonic crystal architectures.

Motion Generator to Transform Linear into Nutation Motion

A nutation motion generator which transforms linear motion into nutation motion. The device employs a spherical, four-bar linkage mechanism. Three four-bar linkage mechanisms are sandwiched between a stationary support surface and a drive plate and arranged at 120-degree intervals about the support surface. Each four-bar linkage mechanism is constructed of four planar sections which are hinged along their edges, the four hinged planar sections being essentially triangular in shape so that they would join at a point in the center of the device if they extended to the apex of their respective triangles. A universal joint is located at the center of the device to provide stability. The four-bar linkage mechanism can be collapsed to a substantially flatten configuration, opened and then collapsed to a substantially flattened configuration at an angle 90-degree. to that of the first flattened configuration. Since each four-bar linkage mechanism has this capacity, the drive plate can be positioned at any angle relative to the support surface. The movement of the four-bar linkage mechanisms is generated by an actuator consisting of three reciprocal-motion drivers connected between the hinged edges of adjacent four-bar linkage mechanisms which are driven by a controlled electric pulse. The reciprocal-motion drivers, for micro applications, are piezoceramic stacks. If the drive plate is circular and its outer perimeter is fitted with beveled gear teeth, a second gear (the "driven" gear), with a smaller diameter than the drive gear, can be meshed with the drive gear to drive the driven gear at a reduced speed and at a relatively high torque. The three-dimensional motion of the mechanism makes the device very compact, and amplification is improved as the device is made flatter. In addition, the interaction between the nutating element and the top of the support surface creates a very large gear reduction.

Image-Guided Navigation System for Endoscopic Eye Surgery

A flexible endoscope for ophthalmic orbital surgery is presented. The endoscope has illuminating fiber, image fiber and a free conduit to deliver purge gas/fluid in addition to instruments such as ablation instruments, coagulating instrument or a medication delivery instrument.

OLINDA/EXM Radiation Dose Assessment Software Application (FDA Approved)

The OLINDA/EXM® personal computer code performs dose calculations and kinetic modeling for radiopharmaceuticals (OLINDA/EXM stands for Organ Level INternal Dose Assessment/EXponential Modeling). OLINDA® calculates radiation doses to different organs of the body from systemically administered radiopharmaceuticals and performs regression analysis on user-supplied biokinetic data to support such calculations for nuclear medicine drugs. These calculations are used to perform risk/benefit evaluations of the use of such pharmaceuticals in diagnostic and therapeutic applications in nuclear medicine. The technology employs a number of standard body models for adults, children, pregnant women and others, that are widely accepted and used in the internal dose community. The calculations are useful to pharmaceutical industry developers, nuclear medicine professionals, educators, regulators, researchers and others who study the accepted radiation doses that should be delivered when radioactive drugs are given to patients or research subjects.

Vanderbilt Performance Evaluation System (VPES) & Job Descriptions Database

Vanderbilt University Medical Center (VUMC) job performance evaluations are part of an annual cycle called performance development in which supervisors and staff members identify and tackle specific job goals with close attention given to the VUMC mission, credo and job descriptions. Many hospital systems, including VUMC, now desire to base annual salary increases largely on performance evaluation ratings. VPES and the Job Description Database allow performance evaluations to be applied consistently and efficiently across the organization.

Core Ordering and Reporting Enterprise System (CORES™)

CORES™ is a highly configurable, enterprise-wide software solution for research institutions. CORES™ provides full central oversight while also allowing for flexible but consistent decentralized billing and usage functionality for core facilities. This software allows core managers and customers to enter orders using a variety of methods. The software also allows customers in product cores to scan their items at a self-service checkout terminal that provides full real-time inventory management. Orders are accumulated into electronic invoices and e-mailed to customers each month. An electronic upload file containing order information is also created for the finance department. Vanderbilt has approximately 90 internal cores using this software. In addition, the software is used by several other institutions to whom the software has been licensed.

Sampling Algorithm for the Reproduction of Complex Digital Signals

This technology utilizes a set of mathematical algorithms that permit fast and robust reconstruction of signals from digital samples without the need to resort to band limitations or uniform sampling. This allows a signal to be digitized in a more sophisticated way, sampling it at frequent intervals when it is rapidly changing, and less often when it is changing slowly. Band limits imposed by uniform sampling are eliminated.

ProcoderDV

Procoder for Digital Video (ProcoderDV) was developed at the John F. Kennedy Center at Vanderbilt University to facilitate the collection of different forms of observational data from digital media files. Media files can be any files that contain events of interest on digital video or audio files. Data files can be of two general types: event files or transcription files. Files can be exported into MOOSES (Tapp & Wehby, 1995) format or SALT (Miller & Chapman, 1993) format or can be read directly by many popular statistical or spreadsheet programs. A code file can be used in conjunction with ProcoderDV to guide the coder inmarking events for later quantification and analysis.

Fault-Adaptive Control Technology Toolsuite (FACT)

The FACT toolsuite assists engineers working with complex aerospace systems to design and implement control systems that can maintain control even when the controlled system "fails." The tool suite uses a model-based approach where the designer creates design models of the plant and its associated control system, and the tools automatically generate code that implements fault-detection, isolation and control reconfiguration functions.

INTMAN Interval Manager for Windows and Pocket PC

Interval Manager (INTMAN) is a computer-assisted alternative to traditional paper and pencil methods for collecting fixed interval time sampled observational data. The INTMAN data collection software runs on Pocket PC hand held computers and includes a desktop application for Microsoft Windows that is used for data analysis. Standard analysis options include modified frequencies, percent of intervals, conditional probabilities, and Kappa agreement matrices and values.
