Radio detection and ranging (radar) uses reflected radio waves to detect and determine the distance, angle, and velocity of objects relative to the radar system. A basic radar system consists of a transmitter producing electromagnetic waves in the radio or microwave spectrum (these can be pulsed or continuous), a transmitting antenna, a receiving antenna (often […]

AutomationDirect has added new stainless steel linear variable inductance transducers (LVITs) from Alliance Sensors Group to their growing lineup of linear position sensors. These sensors convert the linear displacement of an object into a proportional analog output of 0 to 10 VDC or 4 to 20mA (depending on model). The compact LZ13 series has a […]

Football is not only the world’s favorite pastime but also a multi-billion-dollar industry. Individual players can command millions of dollars in salaries and transfer fees. With so much at stake, coaches and scouts need to make the most informed personnel choices, then, keep their players on top condition. For the most advanced real-time empirical data, […]

STMicroelectronics is enhancing vehicle safety with its latest global-shutter image sensors for driver monitoring systems (DMSs). DMSs continually watch the driver’s head movements to recognize signs of drowsiness and distraction, enabling systems in the vehicle to generate warnings that can preserve the safety of occupants. Traffic agencies estimate that about 95% of road traffic accidents […]

In 2022, the Wear 2022 Conference will be held in Scottsdale, AZ, June 7-9, 2022, at the DoubleTree Resort by Hilton Paradise Valley, and available online as well. The annual conference examines the significant breakthroughs and new opportunities made possible through the integration of textiles and technology through wearables. Among the driving forces for wearables […]

The new 36 sensor series from Leuze detects objects even at large operating ranges. Manufacturers and operators of highly automated systems benefit from the cost-optimized design of these sensors. The accurate detection of objects requires reliable technology: Leuze has developed the new 36-sensor series exactly with this in mind: Thanks to their detection performance, these […]

Embedded vision components are ever-popular and being incorporated into a plethora of applications. What all these applications have in common is the need to pack more functionality into tight spaces. Often, it is advantageous for these systems to make decisions on the edge. To enable such systems, including the ability to prototype quickly, Teledyne FLIR has introduced the […]

In today’s supply chain situation, this has to be among the most frequently asked questions (FAQs). However, even under what may have been considered normal times prior to COVID-19, it still is a legitimate FAQ. Tracking shipments that are critical or essential may allow more expensive tracking solutions but if the cost is reasonable, many […]

Researchers at Boston College, Giner Labs and Boston University say the answer is a graphene electronic multiplexed sensor (GEMS) platform that enables the simultaneous sensing of four different target opioid-derived molecules in wastewater samples. The graphene-based field effect transistors detect four different synthetic and natural opioids, while shielding them from wastewater’s harsh elements. The ability […]

If you go to the Wikipedia page on absolute encoders, you’ll find descriptions of these devices mentioning multiple code rings, glass or plastic discs, and configurations of sliding contacts arranged so each contact wipes against a metal disc at a different distance from a turning shaft. Actually, you’d be hard pressed to find any of […]

Superior Sensor Technology announced their ND Series pressure sensors offer advanced air measurement capability that greatly improve the speed and altitude control of drones or unmanned aerial vehicles (UAVs).  Based on the company’s advanced NimbleSense architecture, the ND series pressure sensors are not sensitive to noise, provide extreme accuracy, offer fast response times, use minimal power, and are designed […]

SLAM (simultaneous localization and mapping) is used in autonomous vehicles of all types to build a map and simultaneously locate the vehicle in that map. SLAM algorithms allow the vehicle to analyze and map out unknown environments. With this map information, the vehicle can implement path planning and obstacle avoidance. Visual SLAM uses cameras and/or […]

NewTek Pre-calibrated Linear Position Sensors serve as long-term replacements for potentiometers (pots) that become unreliable over time due to their contacting operation and effects from vibration and other environmental parameters. As potentiometers rely on mechanical contact to provide position feedback, components wear out and are affected by heat, vibration, and humidity, making output progressively noisier […]
