Improving medical imaging with direct radiography Design How-To 9/10/2012 3 comments Traditional analog X-ray imaging systems is being replaced by Direct Radiography. The DR X-ray image is available within seconds after exposure of the patient and can be distributed immediately for consultation with medical experts anywhere. This article focuses on design challenges with respect to digital X-ray flat panel detectors.
Infrared LEDs for camera systems Design How-To 9/7/2012 1 comment This article explains that powerful infrared LEDs, or IRED, facilitate compact illumination units for video and CCTV systems on infrared basis. They reduce the cost for packages, optics, reflectors and production.
Energy harvesting from thermoelectric sources gets a boost Product How-To 9/4/2012 6 comments Powering a wireless sensor node from ambient or “free” energy is attractive because it can supplement or eliminate the need for batteries or wires. This is a clear benefit when battery replacement or servicing is inconvenient, costly or dangerous.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
