Optical Chip is Faster than GPU

Although a typical GPU setup can solve the Ising problem with ease, now a silicon photonics accelerator can also do the same, but at a speed a hundred times faster. The optical computing startup Lightelligence has demonstrated this feat. The photonic arithmetic computing engine from Lightelligence is an integrated optical computing system, and it is known as Pace. It consists of about twelve thousand photonic devices that run at 1 GHz each. Compared to Comet, the earlier 100-device prototype Read more [...]

Why ADC Grounding is Important

We commonly use analog to digital converters in electronic devices. For instance, we connect the output of a sensor to an ADC input and use the digital readings for our purpose. Digital signals offer good noise rejection, there is firm switching between levels, and the built-in margin available is also good. However, the analog side can be susceptible to noise. If the analog input is noisy, it affects the digital output. Most noise levels on the analog side come from a single source—a lack Read more [...]

Improvements in Machine Vision

The way consumers now interact with retailers, banks, and the hospitality industry, has undergone a sea of change. There are many self-service kiosks and ATMs for the consumers to interact, and this is undergoing a revolution. However, these improvements mean the back-end systems must undergo a huge improvement in terms of new hardware, firmware, software, and connectivity. New businesses are getting the most out of their kiosks, with the role of machine vision creating a seamlessly connected Read more [...]

Human-Machine Interaction in Automobiles

In automobiles, there is a need to realize sensing of force, proximity, ambient light dimming, and gesture control with digital optoelectronics components. Optoelectronics sensor devices enable HMI or Human-Machine Interaction. This requires sensing user inputs and lighting conditions, allowing drivers to keep their eyes on the road. It is possible to connect most optical sensors nowadays to the central controller via the I2C interface. By setting the internal settings of ASICs or Application Read more [...]

Dual Board Net Systems in Automobiles

Modern electric vehicles are increasingly using dual board net systems. These contain both a 12 VDC bus and a 48 VDC bus. One of the key building blocks in the architecture of these vehicles is the high-power, bidirectional 48 VDC to 12 VDC converter. Energy flows in either direction between the two batteries—48 V and 12 V. This helps to optimize the overall efficiency of the vehicle. The direction of the energy flow depends on the demands the vehicle’s electrical system places on the batteries Read more [...]

Developments in Autonomous Robots

The recent COVID pandemic had put a lid on air travel. But that is now slowly lifting, and more people are venturing out. Airports are responding with new robots offering food delivery services. The International airport in Northern Kentucky is currently using these Ottobots, made by Ottonomy, a robotics company. The Ottobot is a four-wheeled autonomous robot. At the airport, in the Concourse 8 area, travelers can use a dedicated app to purchase food, beverages, or travel products from select Read more [...]

What is Multi-Point Bluetooth?

It is certainly advantageous to live a wire-free lifestyle—especially with Bluetooth connectivity. However, there is the experience of having to pair earbuds or headphones to consider. Most of the time, the pairing is difficult, takes up considerable time, and is not intuitive. Multi-point Bluetooth helps with these concerns. Using multi-point Bluetooth, it is possible to connect one pair of earbuds or headphones to multiple devices at once. It may not be necessary to execute the annoying pairing Read more [...]
