The Eyeonic Vision Sensor has demonstrated the ability to perceive, identify, and avoid objects at a range of more than 1 kilometer. Having previously demonstrated a detection range of more than 500 m at CES earlier this year, SiLC has now optimized its technology to go beyond 1,000 m–a feat that no other company can […]

Can 60 GHz radar sensing change healthcare monitoring?
According to a 2019 article in Nature,blood pressure (BP) abnormalities, such as hypotension and hypertension, are important risk factors for many short- and long-term critical illnesses, with a global disease impact on about 1.25 billion people [1]. In addition to the high number of people with blood pressure issues, sleep apnea is a rapidly increasing […]
What software-definable sensors are available now?
Sensor designers are pursuing software-defined (or programmable) sensors for their increased relevance and applications in the Industrial Internet of Things (IIoT). Automobiles are one market segment that can benefit from over-the-air (OTA) update capabilities and automakers have the resources to make significant changes to implement them. OTA updates are one way to future proof vehicles, […]
Human presence detection and you
By Charles Pao, Senior Marketing Specialist at CEVA Mobile phones and tablets are getting more powerful, but if you’re serious about doing work (remotely), the dedicated work laptop still reigns supreme. Privacy and productivity have become increasingly important in this new paradigm of working anywhere. To help with both in the age of mobile computing, […]
How can sensors help cleanup waterways?
Twenty years after its first-generation design was introduced (2002), iRobot’s Roomba has spawned many competitors for indoor cleanup and made several advancements to its initial capabilities. Interactive Autonomous Dynamic Systems (IADYS) has applied the autonomous robot concept to address cleaner and safer water in rivers, canals, lakes, ponds, shipyards and more. IADYS’ Jellyfishbot autonomously collects […]
How can a machine recognize hand gestures?
Gesture recognition is a user interface that allows computers to capture and interpret non-verbal communication, including facial expressions, head movements, body positioning, and hand motions as commands. Hand gestures are an increasingly common mode of computer control, and the types of sensors used to recognize hand gestures is growing. This FAQ briefly reviews how hand […]
How many types of radar are there?
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 […]
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 […]
What sensors do you need to land on the moon?
NASA is developing several sensor systems and algorithms for use on Artemis moon landings. It’s called the Safe and Precise Landing – Integrated Capabilities Evolution (SPLICE) technology suite. It consists of three primary elements: An inertial measurement unit (IMU) and a camera for terrain relative navigation. Second is Doppler LiDAR to determine the lander’s velocity […]
How do time-of-flight sensors work?
Using the time-of-flight (ToF) principle, a ToF sensor measures the distance between the sensor and an object. The sensor emits a signal that is reflected off an object and then detects the time for a round trip to occur. Typically, either light or sound waves can provide the transmitted signal. In either case, the distance […]
