Internal Short Circuit Testing Device to Improve Battery Designs
Batteries, such as lithium-ion, sold for consumer use in portable electronic devices and other applications such as electrical cars, occasionally fail in the field over time. These cells have typically passed a wide variety of safety tests such as those required by governmental...
Briefs: Sensors/Data Acquisition
Many applications require detection of both very small and very large signals. High-gain detector amplifiers provide low noise, but are easily swamped by large signals. Logarithmic amplifiers provide a wide...
Briefs: Data Acquisition
In traditional hardwired avionics systems, sensor integration requires installation of literally tons of physical cable that significantly increases vehicle weight and the time...
Briefs: RF & Microwave Electronics
Infrared motion detectors can cover only a limited amount of space, a person has to be within the detector's line of sight to be detected, and lights can go off when a person remains still...
