The Neuromodulation Group at Lahey Clinic conducted a study based upon spinal cord stimulation (SCS). SCS involves implanting a series of electrodes that apply electric potential to the spine, interfering with pain signaling circuitry. It’s used to alleviate chronic back and leg pain. Although the treatment remains effective for years, the electrodes must be reprogrammed through trial and ...

Nordson EFD, East Providence, RI, USA
Veryst Engineering, a company that provides consulting in engineering design and product manufacturing, has collaborated with Nordson EFD, one of the leading manufacturers of precision dispensing systems, to optimize their static mixers. Static mixers are inexpensive and efficient mechanisms for mixing laminar viscous fluids, where molecular diffusion is minimal. Here, the fluids must be ...

Johnson Screens® are the manufacturers of steel screens that impede debris from lakes and rivers from entering pipes and valves that will utilize the water. Their task is to provide application-specific screens that must be customized to the environment they are operating in. Often this means taking into account the characteristics of the debris they are to remove, the depth at which the screen ...
New Haven, CT
Professor Mark Reed and his team at Yale University are using COMSOL Multiphysics to develop a MEMS-based solution for detecting bacteria in blood. Called the ?Screen, it will provide analyses speedily, accurately, and cost-effectively. Such a device would greatly help the food industry in improving meat quality and reducing the risk for infections. Current methods take too long for most food ...

Georg-August-University, Göttingen, Germany
Professor Dr. Martin Sauter leads a group at the University of Göttingen in research on hydrogeology. Cooperating with Hölscher Wasserbau, a leading German dewatering company, the group is studying düsensauginfiltration (DSI), which is a technique for lowering groundwater levels at mining or construction sites. Traditionally, dewatering involves the transportation of water away from the site, ...

In many medical procedures and tests, it is necessary to isolate cells of interest for further analysis. Microfluidics has revolutionized the way in which these tests are conducted enabling, for example, the ability to detect cancer from a blood sample. One of the most promising microfluidic techniques to separate and concentrate cells is called inertial focusing. The equilibrium positions for a ...

Combining acoustic and electromagnetic analyses helps scientists to more efficiently measure and survey subterranean regions. Acoustic waves can travel long distances, but have limitations when it comes to providing details about formation properties, and cannot be used to identify the liquids flowing through them. Electromagnetic waves do not propagate as far as acoustic waves, but can identify ...
VSG, Burlington, MA, USA
VSG provides high-performance 3D visualization toolkits and software for a number of industries, including materials science and geosciences. One application of their technology is with American oil and gas reserves. The difficulty of accessing these sites has forced the industry to turn to the technique of injecting fluid under pressure into rock deposits. This technique requires knowledge of ...
Microvisk Technologies, North Wales, UK
Microvisk Technologies develops and manufactures devices for measuring blood viscosity using the power of Micro Electronic Mechanical Systems (MEMS) and a radical new technique stemming from futuristic research on microtechnology. Older hand-held devices on the market work by inducing a chemical reaction that is picked up by electrodes coated with componds. The MEMS-based micro-cantilever ...
