Easy and Accurate Measurement of Blood Viscosity

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 ...

Capacitively Coupled Plasma Analysis

Luke T. Gritter, Sergei Yushanov, Jeffrey S. Crompton, and Kyle C. Koppenhoefer
AltaSim Technologies
Columbus, OH

AltaSim Technologies provides engineering consulting services involving advanced multiphysics modeling such as capacitively coupled plasma (CCP). Plasma etching and deposition of thin films, critical processes in the manufacture of advanced microelectronic devices, commonly utilize CCP, in which the plasma is initiated and sustained by an oscillating electric field between two or more ...

Picking the Pattern for a Stealth Antenna

F. De Vita, S. Di Marco, F. Costa and P. Turchi
Altran, Italy

Stealth airplanes and ships avoid radar detection by optimizing the shape of surfaces to reflect away from the radar source or absorb its energy. Yet, if a ship or aircraft’s antenna for communication purposes is to operate properly, it cannot be completely covered up. This makes it one of the remaining components with a large radar cross section and can essentially destroy the overall ...

Multiphysics Simulation Helps Miele to Optimize Induction Stove Designs

Christian Schröder
mieletec FH Bielefeld
Germany

Holger Ernst
Miele
Germany

The induction stove was designed to meet a consumer need for better precision and speed than traditional stoves. Designers were tasked with improving the energy efficiency of the induction coils-stovepot interaction considering both the thermal and electromagnetics of the system. Miele, a world leader in domestic appliances and commercial machines, along with researchers from mieletec FH ...

Analysis of Spiral Resonator Filters

S.P. Yushanov, J.S. Crompton, and K.C. Koppenhoeffer
AltaSim Technologies

As the world becomes more digital, there is growing demand for advanced wireless systems. Increasingly high data rate transmission systems mean that components like microwave filters must fit into smaller and smaller spaces, and multiple filters need to be integrated into compact designs. Engineers are challenged to meet a filter's specific passband frequencies and quality requirements within the ...

How Reclosers Ensure a Steady Supply of Power: It’s All in the Magnet

O. Craciun, and colleagues
ABB AG
Ladenburgh, Germany

When a tree branch touches overhead cables and causes a momentary short circuit, your lights may flicker. A device called a recloser ensures that power to your home is not cut off for a longer period. ABB AG, a leading manufacturer in power technology, is working towards designing a more reliable recloser. One objective in this design process was to optimize the size of the permanent magnet ...

Wind Turbine Noise Reduction

Xi Engineering Consultants Ltd, Edinburgh, UK

Xi Engineering Consultants Ltd specializes in complex vibration issues, like those caused by wind turbines. The meshing of teeth within the gearbox of a wind turbine can cause great vibrations which are perceived as excessive noise. This presents a problem as there are strict regulatory standards throughout Europe and North America limiting permissible noise from these structures. Studying the ...

Conjugate Heat Transfer

Luke T. Gritter, Jeffrey S. Crompton, Sergei Yushanov, and Kyle C. Koppenhoefer
AltaSim Technologies
Columbus, OH
USA

This is an application brief describing the concept of Conjugate Heat Transfer, which is important in many industrial processes, such as quenching. In this brief, they simulate the heat transfer with and without phase transformation to analyze the rate of heat dissipation with respect to the flow conditions of the coolant media. The fluid flow conditions could then be modified to produce a ...

Reduced-Weight Reaction Sphere Makes Way for Extra Satellite Payload

Leopoldo Rossini, Emmanuel Onillon, & Olivier Chetelat

CSEM SA, Neuchatel, Switzerland

CSEM is a private applied research and development center specializing in micro-technology, system engineering, micro-electronics, and communications technologies. One of their latest projects is working on minimizing the weight of satellite attitude control systems as every gram of payload matters when launching a satellite into orbit (€15,000 per kilogram). CSEM hopes to accomplish this task ...
