Oak Ridge, TN —Designers of medical equipment and diagnostic systems should check out progress on the Virtual Human project being lead by the Oak Ridge National Laboratory (ORNL; www.ornl. gov/virtualhuman). This collection of assets on the Internet is aimed at modeling organs and their behavior on the systems level. The project looks to establish servers with resources, including: libraries of physiological models and anatomical data (for developing equivalent physical "phantom" models of various organs that can be made for device testing); actual patient data (such as EKG and EEG traces); and databases of metabolic and bioprocesses. These would all be linked by a "client" user interface.
For designing seat belts or airbags, for example, designers could use the Virtual Human to study how the organs in the chest would respond to and be affected by a blunt-object or accident trauma. Organ exposure to toxins, such as mercury vapor inhalation, and treatment could also be modeled. With precise models of "well" and "problem" physiological characteristics, designers of safety, medical-imaging, and diagnostic systems will be able to evaluate effectiveness of products earlier in the design cycle.
The new small-form-factor EZ-BLE PRoC (Programmable Radio on Chip) module is a derivative of the existing PRoC BLE Programmable Radio-on-Chip solution. The EZ-BLE PRoC module integrates the programmability and ARM Cortex-M0 core of the PRoC BLE, two crystals, an onboard chip antenna, a metal shield, and passive components.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
