The Three Rs of Analog Position Sensor-Based Mechanical Measurements

  • Magazine Article
  • TBMG-35681
Published 2019-12-01 by Tech Briefs Media Group in United States

Those of us old enough to remember the “good old days” recall that grade school focused on learning the 3 R's: reading, ‘riting, and ‘rithametic. In the world of sensors, there are also 3 R's: Repeatability, Resolution, and Response. As important as these sensor parameters are, there is often confusion in the mind of users about exactly what they mean and in what ways they tend to interact with each other. This article will attempt to explain the 3 R's for position sensors and dispel any confusion that might exist.

Implantable Cancer Traps Could Provide Earlier Diagnosis, Help Monitor Treatment

Design teams are targeting focused markets for their commercial electric-vehicle programs to combat challenges like range and infrastructure.

Government regulations are prompting a changeover to electric powertrains, with early growth coming in commercial vehicle applications where range and recharging are more easily managed. Greater expansion will require revisions in maintenance and broader availability of charging stations as well as improved driving ranges.

Published 2019-12-01 by SAE International in United States

Fuel-cell technology is a big subject with some very small but vital aspects, one of which is the size of platinum atoms. Reduce these and the cost of platinum-one of the major drawbacks of current fuel-cell systems-would also fall. So, establishing and creating the optimum size for platinum fuel-cell catalysis for cars and heavy-duty trucks is one of the ongoing research areas for future alternative energy solutions.

MMOD Impact Detection and Location

  • Magazine Article
  • TBMG-35686
Published 2019-12-01 by Tech Briefs Media Group in United States

Determination of micrometeoroid/ orbital debris (MMOD) impact on orbiting spacecraft currently requires visual inspection. For human-rated spacecraft such as the International Space Station (ISS) and previously, the Space Shuttle Orbiter, this has required crew time as well as vehicle assets to identify damage due to MMOD strikes. For unmanned spacecraft, there are no human assets present to conduct detailed surveys to ascertain potential damage.

Potassium-Oxygen Battery Stores Clean Energy

  • Magazine Article
  • TBMG-35692
Published 2019-12-01 by Tech Briefs Media Group in United States

Researchers have developed a more efficient, more reliable potassium-oxygen battery with a cathode that stores the energy produced by a chemical reaction in a metal-oxygen or metal-air battery. The battery could make renewable energy sources like solar and wind more viable options for the power grid through cheaper, more efficient energy storage.
