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 [...]

Illuminating Automotive Displays

In recent years, there has been a substantial improvement in automotive displays. Automotive manufacturers now integrate these displays in various applications within the automobile, such as in mirror replacements, central information displays or CIDs, instrument clusters, entertainment displays for the rear seats, and many more. Sometimes, such displays can total up to twelve per vehicle. Most of these displays use thin-film transistor or TFT driving liquid crystal displays or LCD for enhanced Read more [...]

Retail Energy Management through IoT

Most people prefer to visit big stores like Walmart and Costco for buying almost everything from iPhones to ice-creams. But running huge stores is not an easy task, and the superstores are always on the lookout for ways to cut costs by streamlining their operations. With superstores the size of a city block, streamlining operations is not simple. Substantial resources—time and staff—are necessary to keep store lighting, food court ovens, HVAC systems, and digital displays running at maximum Read more [...]

Sensors for Structural Health Monitoring

Public bridges and roads require their structural health to be monitored, and engineers use sensors for continuous measurement. To power these embedded sensors, they exploit several sources of ambient energy. This can include vibrational energy obtained from vehicular traffic, which can generate adequate power for sensor nodes that engineers have built into the infrastructure. Off-the-shelf devices make it easier for engineers to design structural monitoring devices. Many manufacturers now provide Read more [...]

 Important Sensors

Engineers use two important types of sensors—superstar sensors and workhorse sensors. The superstar sensors usually provide information in high-profile applications such as advanced driver assistance systems, and engineers update them regularly for improving their performance. On the other hand, the workhorse sensors are more reliable, providing consistent information on more common applications. These workhorse sensors are simple to use, and meet the necessary performance specifications at reasonable Read more [...]
