Using laser-sourced light beams rather than wireless RF to link spacecraft with Earth offers the possibility of a significant increase in data rates. Still, there are significant technical challenges to the concept. The previous part of the article established the need for higher-speed data links to spacecraft and their missions and looked at some of […]

Optical links for spacecraft, Part 1: The throughput limitation
Using laser-sourced light beams rather than wireless RF to link spacecraft with Earth offers the possibility of a significant increase in data rates. Still, there are significant technical challenges to the concept. Scientists, engineers, and researchers communicating with spacecraft have a problem: there’s so much data coming from these spacecraft – and to send to […]

Single-chip AFE integrates optical, ECG, and bio-impedance measurement systems
Simplify the design of wearable remote patient monitoring (RPM) devices by measuring four vital signs with one MAX86178 triple-system vital signs analog front end (AFE) from Analog Devices, Inc. This single-chip AFE integrates three measurement systems (optical, ECG, and bio-impedance) to obtain four common vital signs: electrocardiogram (ECG or EKG), heart rate (ECG or optical […]
Thermal dielectric filler eliminates contamination in high-voltage applications
Henkel announced the commercial launch of Bergquist Gap Filler TGF 3000SF, the latest in the company’s line of silicone-free thermal interface materials (TIMs). With significantly higher thermal conductivity than any previous silicone-free liquid formulation in its portfolio and delivering impressive dielectric strength, Henkel’s new material extends wider market opportunities and production flexibility to manufacturing operations […]
How chipless RFIDs will revolutionize consumer and defense applications
by Kishor Kanada, Allied Market Research Researchers from Somark Innovations launched biocompatible RFID ink that can be used for tattooing laboratory rats and cattle. The ink can be colored or invisible and uses RFID technology with no metals or chips. The usage of chipless RFID in the creation of ink would eliminate the issue of […]
