Powering The Internet Of Everything — Without Batteries Or Wires
Apparently the term Internet of Things (IoT) wasn’t comprehensive enough; now it’s the Internet of Everything (IoE). Whatever you choose to call it, the movement to connect just about everything imaginable to the Internet is well underway — and is expected to proliferate wildly in the coming years. According to Cisco, there will be approximately 50 billion connected objects by 2020, but how will we power them all?
RFID-Enabled Breast Implants And The Future Of Medical Device Tracking
A device hailed as the “world’s first externally identifiable breast implant” has received CE Mark approval, enabling physicians in Europe (and other parts of the world) to immediately ascertain manufacturer name, serial number, lot number, batch number, and other implant-specific data in vivo — by merely scanning the area outside the body with a handheld reader. What can this development tell us about RFID's role in facilitating UDI compliance, preventing counterfeiting, minimizing product recall impact, and more?
Microwave Oven = Smartphone Charger: Will RF Energy Harvesting Make It Possible?
mImagine setting your dead smartphone down on the kitchen counter as you grab a frozen dinner out of the freezer. You pop the meal in the microwave, hit the start button, and viola! — 5 minutes later you have both a hot, nutritious meal and a charged phone. Sounds too good to be true, right?
True Differential Measurements- Characterization of Balanced Devices
Differential devices offer advantages like noise immunity, low crosstalk, high integration density, and reduced power consumption. However, they also require special measurement capabilities. There are essentially two different measurement methods available: virtual measurements, and true differential measurements.
Data rates in the range of several Gigabit/s are needed to transmit signals like uncompressed video signals. Amendment 802.11ad to the WLAN standard defines the MAC and PHY layers for very high throughput (VHT) in the 60 GHz range. This white paper provides an introduction to the technology behind 802.11ad and highlights the test and measurement requirements.
This case study explains how CST STUDIO SUITE® electromagnetic simulation software can be used to help with antenna placement and co-site interference, electromagnetic environmental effects, and other factors that should be considered when designing or specifying an antenna for use in a defense-related application.
This white paper offers detailed information on the potential power integrity issues from power plane interactions in PCBs, and information on how to combat these issues through simulation software.
This White Paper provides a more detailed view on radar waveforms for Aerospace and Defense and commercial radar systems. Waveforms such as pulse and pulse-Doppler signal, continuous wave and frequency shift keying waveforms are described.
Patterned Ground Shields For Silicon RFICs – Part 3: Which Way Does The Current Really Go?
Everything is so confusing. In Part I of this series, we found that there is something really strange about the current flowing in an Si substrate underneath a spiral inductor. It is flowing perpendicular to the direction of the spiral turns, when we thought it should be flowing parallel to the turns. This is part of a series of guest columns by Dr. James C. Rautio of Sonnet Software, Inc.
Remote Monitoring And Measurement In Communications Systems
In early October 2013, I was part of a panel discussion on test and measurement trends at the Tessco product show in Baltimore. One thing all the manufacturers there agreed on was the need for more remote monitoring and measurement.
Testing Modern Radar System Signals: A Primer
The demands placed on modern radars create challenges for both the radar designer and test engineer. Advanced radar systems require greater precision to measure narrower pulse widths and/or to examine intra-pulse behavior with finer resolution, including rise/fall edge effects or the profile within a pulse compression signal. In order to best understand the complexity of testing today’s radar designs, it is good to first review some basic applications of radar systems and the fundamentals of pulse measurements.
