What is the key to understanding the depth of an Artificial Intelligence (AI) algorithm’s unique power? Jeff Harris from Keysight Technologies shares his insights into how measurement determines the potential of your AI algorithm.
Determining the potential of your AI algorithm begins with measurement.
At the core of every AI algorithm are three basic ingredients:
- the ability to measure
- knowing how much of what you measure needs to be processed
- the ability to process more than one input at a time
To what depth a system can measure can be thought of as its potential.
Determining what aspects of those measurements must be sent to the processor can be thought of as delivering that potential.
Finally, knowing how to combine the salient parts of those measurements in the correct proportions, known as sensor fusion, is the key to exploring an algorithm’s IQ or reasoning potential.

We frequently see DDR SDRAMs as a key specification of computers and digital devices. In this two-part guest commentary, Ben Miller from Keysight Technologies shares his insights into the design of DDR SDRAMs (Part 1) and how faster memory speeds shape the future (Part 2).
DDR5 is still in the early phases of adoption. JEDEC released the standard in July 2020. The first CPU platform to support DDR5 was released in early 2022.
However, this platform still includes DDR4 support, so it could be some time before the industry accepts DDR5 as the de-facto memory standard and fully transitions memory systems to the new standard.
Faster memory enables the future
Over the next couple of years, more personal computers, servers, and embedded systems will take advantage of the higher speed, lower power, and greater memory capacity available with DDR5.

We frequently see DDR SDRAMs as a key specification of computers and digital devices. In this two-part guest commentary, Ben Miller from Keysight Technologies shares his insights into the design of DDR SDRAMs (Part 1) and how faster memory speeds shape the future (Part 2).
Faster data processing requires faster memory.
Double data rate synchronous dynamic random-access memory (DDR SDRAM) enables the world’s computers to work with the data in memory.
Faster, not wider
Since the origins of SDRAM, engineers have faced challenges with increasing memory speeds.

DDR emerged as a faster, more efficient way to handle memory, while providing a universal standard between chip designers and device manufacturers.
As shown in Figure 1, DDR memory consists of a memory controller which transmits clock, address and control signals, and a series of DRAM chips which store the data.
In a write operation, the controller sends data and strobe signals to the DRAM; in a read operation, the DRAM sends data and strobe signals back over the same bi-directional line.
DDR SDRAM became the standard in the late 1990s and has since been improved upon many times over.
Prior to DDR, memory speeds maxed out in the range of 100 MT/s.

The world is coming to terms with having to live with COVID-19 for a while to come. Apart from population-level vaccination to enhance our resistance against the disease, how can we make our living and working environment safer from the SARS-COV-2 virus that causes the disease?
Jitender Khurana shares how UVC disinfection technology provides an effective means of sanitising the air and surfaces around us in an efficient and sustainable way. Most importantly, it can be implemented at scale without breaking the bank! Jitender Khurana is the Country Head & Managing Director for Singapore and Emerging Markets, Southeast Asia at Signify.
When will life go back to what it was like in pre-pandemic days? Will it ever? Image: Signify.
After more than two years and six million deaths globally, the world is still reeling from the humanitarian and economic fallout of the COVID-19 pandemic. The SARS-COV-2 virus has infected almost half a billion people around the world to date, and continues to cause more than a million new cases of COVID-19 every day.
However, the pandemic shows no sign of slowing down, following the scourge of the Delta variant which swept across the earth, as well as the current Omicron variant.
“For true endemic living, I want to be able to attend concerts, work out at a gym, watch an indoor sports event and visit a public bathroom knowing that the air I’m breathing is safe from the SARS-COV-2 virus. All these aspirations can be fulfilled through air disinfection solutions harnessing UV-C technology – in conjunction with wearing masks, social distancing and vaccination.”
Even though no end is in sight for the pandemic, life and business must go on. Governments and companies need a solution that will provide employees and citizens with a safe working and public environment that is protected from COVID-19.
Like it or not, COVID-19 is not going away and all of us will have to learn how to live, work and play while the SARS-COV-2 virus hangs around us and the disease becomes endemic.
Welcome to the new normal of “Endemic Living”.
The silver lining in the cloud is that we have learnt much since the beginning of the pandemic – about the disease itself, the virus that causes it, the way it spreads, the safety measures and practices that would protect us from infection.
I believe we are ready to embark on this new phase of the pandemic, because we are equipped with the know-how and wherewithal to live safely and normally despite COVID-19. We now know that the reason COVID-19 is so contagious is that it can be transmitted over the air.

Every network has a security vulnerability – where is yours? In this guest commentary, Keith Bromley from Keysight Technologies shares a three-point plan on how to find your security vulnerability before hackers beat you to it.
One of the top questions on the minds of network security personnel is “how do I reduce my security risk?”
Even for smaller organisations this is important because every network has a weakness. But, do you know where you are the most vulnerable? Wouldn’t you like to fix the problem now, before a hacker exploits it?
Here is a three-point plan that works to expose intrusions and decrease network security risk.
Network security – It all starts with prevention
Inline security solutions are a high impact technique that businesses can deploy to address security threats. These solutions can eliminate 90% or more of incoming security threats before they even enter your network.

The fully autonomous vehicles of the not-so-distant future promise tremendous gains in automotive safety and transportation efficiency.
In this guest commentary, Thomas Goetzl from Keysight Technologies shares his insights on how automotive OEMs must move beyond contemporary levels of vehicle autonomy to fulfill this promise.
Keysight’s Radar Scene Emulator (RSE) closes the gap between software simulation and roadway testing, and training ADAS and autonomous driving algorithms to real-world conditions.
SAE International (formerly the Society of Automotive Engineers) defines six levels of vehicle autonomy, with Level 0 representing fully manual and Level 5 representing fully autonomous.
Today’s most advanced autonomous vehicle systems rate only Level 3, which means they are capable of making some decisions such as acceleration or braking without human intervention.
“In order to make the leap to the tremendous gains in automotive safety and transportation efficiency that fully autonomous vehicles promise, OEMs will need to overcome a unique set of challenges for testing automotive radar sensors in advanced driver assistance systems (ADAS) and autonomous driving systems, as well as developing new methodologies for training algorithms that conventional solutions are ill-equipped to address,” says Thomas Goetzl, vice president of automotive and energy solutions at Keysight Technologies.
Getting from Level 3 to Level 5 will require many breakthroughs, including closing the gap between software simulation and roadway testing, and training ADAS and autonomous driving algorithms to real-world conditions.
Keysight’s latest innovation, the Radar Scene Emulator (RSE), goes a long way toward bridging these gaps.
Software simulation plays an important role in autonomous vehicle development.
Simulating environments through software can help validate the capabilities of ADAS and autonomous driving systems.
But simulation cannot fully replicate real-world driving conditions or the potential for imperfect sensor response — something that fully autonomous vehicles will inevitably have to contend with.
OEMs rely on road testing to validate ADAS and autonomous driving systems prior to bringing them to market.
While road testing is and will continue to be a vital and necessary component of the development process, it is time-consuming, costly, and difficult to repeat specifically in the area of controlling environmental conditions.
Relying on road testing alone to develop vehicles reliable enough to navigate urban and rural roadways safely 100% of the time would take decades.

In today’s electronics applications, batteries power nearly all of our portable electronic devices. Batteries also serve as emergency power backup systems on large premises. And all-electric vehicles use large cascading battery packs to meet the expected power for the required performance.
In this guest commentary, Bernard Ang from Keysight Technologies shares his insights on specialised battery testing.
Batteries are the key to our portable/mobile electronic gadgets in this digital era.
Battery packs need the required specific power (W/kg) to be able to dispense enough current to achieve the electric vehicle speed performance.
They also need the required specific energy (Wh/kg) to achieve longer runtime or travel range.
Why is it important to monitor battery temperature?
Most rechargeable batteries today are lithium ion and have an operating range between 15 °C and 35 °C at which their full performance and capacity kicks in.
- If the battery and its ambient temperature is below 15 °C, you may experience sluggish electrochemical reactions within the battery and as a result, lower battery performance and reduced charge capacity.
- If the battery or battery pack operates above 35 °C in ambient temperature, battery degradation can accelerate over time. As a result, you may notice shorter battery life, non-uniform aging due to thermal gradients, greater exposure to safety issues, and higher life cycle costs. At extremely hot temperatures, batteries can break down and cause leakage, smoke, fire, and even explosions.
The power map chart below shows the power limits of your lithium-ion battery or battery packs across the temperature range.

In this two-part guest commentary, Carrie Browen and Kevin Kershner from Keysight Technologies share their insights into the future of high speed in-vehicle display and sensor connections. You may find Part 1 here.
For this second half of our commentary, we begin with an introduction of SerDes.
In today’s infotainment systems, it is common for in-vehicle cameras and displays to be connected to the image-processing electronic control unit (ECU) via a SerDes (serializer/deserializer) connection.
Future Prediction
More cameras, more connections, and more sensors with greater accuracy, less weight, and increased safety.
Undoubtedly, there will be a need for an in-vehicle network to seamlessly handle these challenges.
Those in-vehicle networks will need to be tested, they will need to be interoperable, and they will need to be secure.
Today, they are delivered by individual vendors using closed, proprietary standards.
Extending the reach of feature-rich SerDes links can require operating at lower Baud rates and higher order modulations (e.g. PAM-4).
In addition, it will require higher bandwidth Ethernet links as primary interconnects between zones, perhaps with 802.3ch support up to 10 Gbps throughput.
Emerging SerDes standards like mobile industry processor interface (MIPI) A-PHY (MIPI A-PHY is a physical layer specification targeted for ADAS/ADS surround sensor applications and Infotainment display applications in automotive) and Automotive SerDes Alliance (ASA) will be implemented by multiple silicon vendors.
This will create a competitive market that acts to drive down the cost while delivering application specific features.
