Assisting An Aging Population: Designing Medical Devices With Force Sensing Technology

With the geriatric population on the rise, design engineers are challenged with designing responsive, noninvasive, user-friendly medical devices that cater to the needs of an older generation. Patients are looking for cost-effective, easy to use assistive tools that help them regain independence and confidence in their everyday life. Force feedback is a key feature for many of these devices that provide the user and doctor with great insight that ultimately results in better quality of life for the patient. Medical devices with force feedback allow design engineers to create innovative products that differentiate them from the competition.

Coming Soon - Multiphysics Flow Simulations

Computational fluid dynamics (CFD) is often included in multiphysics analyses as a way to understand fluid flow, as well as being the convective mode for other physics. In this webinar, we will explain how to simulate CFD applications in COMSOL Multiphysics® including laminar, turbulent, and multiphase flows interacting with structures (FSI). We will also examine mass transport, electromagnetics, and heat transfer.

Quantitative Analysis of Failure Mode in Adhesively Bonded Test Specimens

A fluorescence visualization technique is used. Langley Research Center, Hampton, Virginia After adhesively bonded mechanical test specimens have been tested to failure, the failure mode must be interpreted and quantified. Areas of the adherent that are bare (no residual adhesive remains) have undergone adhesive failure. The remainder of the surface has undergone cohesive failure. The ability to distinguish and accurately quantify the relative amounts of cohesive and adhesive failure on a failed bonding surface is of tremendous importance in the field of mechanical testing, and for the development of bonded assemblies. Some adhesives (and adherents) are fluorescent, meaning they re-emit light at a different wavelength after being irradiated by some lighting source. This property allows for quantitative analysis of the adhesive failure mode (adhesive and cohesive). A digital image of the fluorescing adhesive or adherent can be analyzed and quantified using publicly available software to determine the relative areas of exposed and covered adherent surface.

Energy-Based Acoustic Measurement System for Rocket Noise

Marshall Space Flight Center, Alabama Development of the next generation of spaceflight vehicles has prompted a renewed focus on sound source characterization and near-field propagation modeling. Without advancements in these areas, large uncertainties in vibro-acoustic loading estimates on space vehicles and payloads may result in structural designs that are either insufficient or excessive.

Mass Gauging Demonstrator for Any Gravitational Conditions

Marshall Space Flight Center, Alabama This concept uses an optical interferometric method to determine the density and/or pressure of the gas state contained with tank ullage. The system is similar to compression tank volume methods. By using an optical interferometric technique to determine gas density and/or pressure, a much smaller compression volume or higher-fidelity measurement is possible.

Multiport Hat Coupler for Electronically Steerable Antenna Testing

This technology provides the same performance as an anechoic closet, but at two orders of magnitude lower cost. Lyndon B. Johnson Space Center, Houston, Texas This invention provides a lower-cost means for verifying the scanning functionality of an electronically steerable (i.e. phased array) antenna (PAA) compared to existing methods that use a scanning probe or scanning test fixture and surrounding anechoic enclosure. This design is comprised of a standard test hat that has been modified to include additional probes located in the positive and negative directions of each scan axis. RF measurements taken from these additional probes provide an estimate of the beam-pointing angle. This solves the problem of verifying the platform-installed antenna’s beam-pointing functionality without the relatively high cost of a conventional anechoic chamber with a scanning probe or scanning test fixture.
