Hyundai-Uber driverless aero taxi.

I signed up to visit the Consumer Electronics Show (CES 2020) earlier this month with great expectations. Based on the agenda, the Las Vegas Convention Center exhibit floor would showcase tons of technology while the numerous panel sessions would cover the most disparate subjects, from robots to artificial intelligence (AI) to virtual currencies. It would be a great opportunity to brush up on new technology trends and test my opinions about some of its most lofty promises. In the end, I got more than I bargained for.

Reno Rossetti  By: Reno Rossetti
 Principal Writer, Maxim Integrated  


Bluetooth Beacons in the Smart Factory

Industry 4.0 has given us smart factories, which are highly digitalized and connected for adaptive manufacturing as well as increased throughput. The increased intelligence in these manufacturing facilities is not only enhancing productivity, but it's also making it possible to identify and fix any breakdowns on the factory floor in real time with little human intervention. For the past several decades, automation has been the key driving force in increasing factory efficiency. With advances in communication, big data, artificial intelligence (AI), and the internet of things (IoT), we are moving ever closer to making factories truly smart.

Getting to Reliable Sensor Data: Interaction Between Electronics, Optics, and Mechanical Design

January 15, 2020

Szukang Hsien  By: Ian Chen
 Executive Director, Industrial & Healthcare Business Unit, Maxim Integrated  

LED light paths

Getting reliable sensor data is complex. For example, an optical heart-rate sensor is actually sensing the changes in an electric current. Heartbeats cause the volume of arterial blood to change synchronously with each pulse. The change in volume changes the amount of light absorbed and reflected as it travels through live tissue. When that light exits the tissue and enters a photodetector, it changes the output current. By creating a sensing system that carefully sets up a proper series of “dominos,” a current sensor becomes a heart-rate sensor.

Add Diode ORing Without Losing Efficiency

January 9, 2020

Travis Taylor  By: Travis Taylor
 Applications Engineer, Advanced Sensor Products, Maxim Integrated 
 

Diode ORing

Wearable and handheld electronic design comes with an inherent tradeoff between battery life, feature richness, and size. To fit the most features in a small device, you want the smallest, most efficient power management scheme. For simple battery-powered devices, all you often need is a diode ORing. A diode ORing powers the device from the battery when unplugged and switches to the charging cable when plugged in. This simple scheme uses two diodes to select the option with the higher voltage. However, diodes have an inherent tradeoff between forward voltage, leakage, size and cost, where you generally get to pick two.

Simplify System Power Design for Your Automotive Displays

January 8, 2020

Automotive displays

The Tesla Model 3 is changing our impression of the vehicle dashboard. Gone are the multiple gauges, buttons, and knobs that we’re accustomed to. Instead, when you step into the driver’s seat, the car’s 15-inch touchscreen takes center stage, providing access to all driver controls. When it comes to automotive displays, vehicle manufacturers are starting to incorporate more screens—and bigger, sharper ones—inside their cabins. Displays for functions such as advanced instrument clusters, heads-up displays, infotainment, center displays, rear-seat entertainment, and smart mirrors are delivering vivid images of the surrounding environment, automotive controls, and infotainment options.

Isolated Power Converter Circuit

Hi Michael,

I've heard that gallium nitride (GaN) and silicon carbide (SiC) could replace MOSFET and IGBT power switches in the near future. The fact that they are smaller and faster sounds great, but as always, I suspect there's no such thing as a free lunch. Are there any pitfalls that I need to be aware of before I start looking at using GaN and SiC in my designs?

Why New ICs Are Needed to Bring Intelligence to the Edge

December 10, 2019

Anil Telikepalli  By: Anil Telikepalli
 Managing Director, Core Products Group, Maxim Integrated 


Object identification application

Computing has seesawed between centralized and distributed models, from mainframes to enterprise servers and then to cloud computing. Each of these cycles has not completely replaced the previous architecture, but, rather, added to it to cater to differing needs past the hype cycle. With edge sensors and AI inferencing, we are now moving past the hype cycle for data centers towards increasing intelligence at the edge and processing the resulting data right there. With billions of edge devices, the demand for low latency has increased. It is incredibly inefficient to collect data from billions of edge devices to a central data center for computation when there is no inter-relationship among the data. Not to mention large, inefficient data pipes and high latency. This has opened the door for low-power, low-latency, distributed edge-computing devices.

Hi, Michael:

I'm having a problem you might be able to help me out with. I'm designing an industrial sensor, but I'm struggling with the power budget to make it work with the IO-Link® connectors. The problem is that the regulators and LDOs on the IO-Link transceivers I've been looking at aren't efficient enough for the amount of current I need. Also, the sensor enclosure is too small for me to use a separate DC-DC converter. Any ideas?

How Wearables Can Become a More Integral Part of Healthcare

Healthcare Wearables

The future of healthcare could be even more data-driven and personalized than it is today. Instead of determining that a patient has a light fever based on a thermometer reading of 37°C, a diagnosis would be based on a comparison of an elevated resting body temperature against a similarly observed baseline from that individual. Rather than an arbitrary (or worse, financially driven) model where patients visit their doctors for sparsely scheduled checkups, people may receive care based on a cadence optimized to their own unique situations.

How an Old Digital Dog Can Learn New Analog Tricks

I have a confession: I'm not really an analog person.

For pretty much my entire career, I've been working with microcontrollers and hooking them up to other, mostly digital, blocks. Freed from the uncertainties that plague the analog world, I could build large, complex systems out of digital logic, content in the knowledge that as long as I didn't push things too far, I could connect pretty much any digital output to pretty much any digital input, and the system would "just work."
