Meeting technical specifications for use in commercial aircrafts, ITT Interconnect Solutions’ custom ARINC 600 connector is designed specifically for in-flight entertainment (IFE) systems. The device uses Quadrax contacts for gigabit Ethernet channels, as well as a custom-size two shell designed to reduce EMI/RFI emissions. The connector utilizes custom insert arrangements and pre-loaded inserts with tail contacts to eliminate unused positions and for PC board
Managing LED and cold cathode fluorescent lamp (CCFL) display backlighting, TAOS’ TCS3404 and TCS3414 digital color light sensors use RGB filters to derive the color chromaticity and illuminance of ambient light with 16 bits of resolution. The 2.095 mm × 1.875 mm × 0.685 mm components automatically eliminate signal fluctuation resulting from AC lighting flicker without
Touchscreen technology has become more prominent in recent years, especially in the consumer and kiosk markets. PDAs, ATM machines, supermarket check-outs, and Apple’s iPhone are among the most well-known uses of touchscreen technology. Some touchscreen technologies have found a place in applications where the more commercially known technologies (resistive and capacitive) are inadequate. This month, we review the different types of touchscreen technologies available for the consumer electronics industry, along with their pros and cons, their applications, and a look into the future.
Everyone is worried about the global economy, and many are afraid that the U.S. electronic design and manufacturing industry is facing dire straights. To those who worry, I say that the primary American electronic markets are amongst the most economically stable places in this crisis, and have some of the most innovative and creative engineers in the world.
Utilizing 4-channel multiplexed technology, Gigahertz-Optik’s X1-1 handheld multi-spectralband filter radiometer simultaneously operates and displays multiple detector measurements of the XD-450X 3-cell detector series.
