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 […]
Sensor Fusion
What’s the difference between network security and physical security?
Network security involves software and computer-based hardware/firmware to provide access to the authorized and restrict access to the unauthorized. In contrast, physical or brick and mortar security starts with sensors and, if the security system is connected to the internet, it also requires the same network security measures. Protecting a residence, commercial building or an […]
How can AI/ML improve sensor fusion performance?
Sensors are becoming ubiquitous as their price and availability continue to improve. However, sensor data is not that simple and is prone to noise and other interference. The complexities of sensor data have led to sensor fusion that aims to perform better than a single sensor by improving the signal-to-noise ratio, decreasing uncertainty and ambiguity, […]
How are sensors improving maritime navigation?
Of course, GPS is important, but radar and the automatic identification system (AIS) use various sensors to track and report on ship positions in real-time. Sensor fusion is being developed for autonomous shipping. And there are hydrophones combined with other sensors and artificial intelligence (AI) and machine learning (ML) to identify and track whale movements […]
Stray-field compensated position sensors feature redundancy function, digital output interfaces
TDK Corporation expands its Micronas 3D HAL sensor portfolio with the Hall effect sensors HAR 3900 and HAR 3930. The products enable stray-field compensated position detection in automotive and industrial applications while addressing the need for ISO 26262 compliant developments. Samples are available on request. The start of production begins in the second quarter of […]
What is the role of sensor fusion in robotics?
As robots become increasingly autonomous, sensor fusion is growing in importance. Sensor fusion merges data from multiple sensors on and off the robot to reduce uncertainty as a robot navigates or performs specific tasks. It brings multiple benefits to autonomous robots: increased accuracy, reliability, and fault tolerance of sensor inputs; extended spatial and temporal coverage […]
How to design an effective telehealth system
By Marcel Consée, Mouser Electronics Healthcare can be deeply personal, and direct contact between patients and medical personnel remains vital. However, taking the relationship between doctors and nurses out of the equation can sometimes make sense. Medical crises such as the global COVID-19 pandemic accelerate the adoption of telehealth methods, even though the original idea […]
What kind of growth is expected in 3D sensing?
According to the report, “3D Sensor Market by Type” the global 3D sensor market is expected to grow from USD 2.9 billion in 2020 to USD 10.0 billion by 2025, at a compound annual growth rate (CAGR) of 27.9%. The market researchers acknowledge that one of the main driving factors of 3D sensor market is […]
How can you achieve a low power sensor node?
At Sensors Expo 2019 in San Jose, CA, Chet Jewan, Vice President of Sales and Business Development at Eta Compute, describes the demos in his booth. The sensor node consists of the Eta Compute ECM3531 application specific integrated circuit (ASIC), a ROHM Semiconductor RF device and sensors – all running off of a small solar […]
What’s new in sensors for autonomous vehicles? Part 1
Tesla, one of the leaders in autonomous, self-driving vehicles boasts 8 vision cameras, 12 ultrasonic sensors and radar on all of the vehicles it is currently building according to recent company tweet. To make the right decisions by using the data from these sensors in the timeliest manner through sensor fusion, Tesla has developed a […]
