With the support of connectivity companies such as Amazon, Apple, Google, Samsung Electronics, and more, the Connectivity Standards Alliance (CSA) announced the Matter standard in October 2022. The standard’s intent is to provide secure and easy-to-configure interconnected products for consumers. That type of interconnectivity is essential to smart homes. When Matter 1.2 was announced in […]
How current sensing impacts electric vehicles: part 2
Part 1 of this blog addressed current shunts and Hall-effect sensor designs. This part discusses current transformers and new technology options, such as magnetoresistance and diamond quantum sensors. One of the significant issues in today’s electric vehicles (EVs) is the ongoing evolution of technology, with the standards evolving as well. In the 100+ years that […]
How current sensing impacts electric vehicles: part 1
The need to transition from gasoline and diesel (fossil fuels) powered vehicles to electric vehicles (EVs) to reduce carbon dioxide levels has revealed many controversial issues. Common issues include implementation timing, required infrastructure (including fast-charging multi-vehicle systems), legislated rather than consumer-based adoption, ongoing system enhancements, and new critical raw materials sources. Current sensing technology is […]
How can awareness of the need for CO sensors be increased?
Public outcries for reducing carbon dioxide (CO2) emissions to reduce their climate change impact have been widely promoted for more than two decades. However, attention to a more immediate public health problem from carbon monoxide (CO) has not received anywhere near the same level of attention– unless the deaths get news coverage. For example, in […]
How is sensing used to detect glaucoma?
The term glaucoma is used to describe a group of eye diseases. In addition to damaging the eye’s optic nerve, glaucoma can result in vision loss and even blindness. About 3 million Americans have glaucoma, but the disease affects more than 67 million people worldwide and is the second leading cause of blindness. Glaucoma occurs […]
How is sensor fusion used in medicine?
Sensor fusion is most frequently discussed in smartphone and automotive control applications. However, the fusion aspect was initially created for military analysis. From the analysis standpoint, for improved decision-making, medical applications can and have benefited from sensor fusion. One example is in cancer detection and focused surgery. Specifically, the detection of and surgery for prostate […]
How do diffuse, retroreflective, and through-beam ultrasonic sensors differ?
Ultrasonic frequencies are above the human audio range — higher than 20 kHz. Operating in this frequency range, ultrasonic sensors are commonly used for measuring proximity (distance), determining the level in storage tanks, detecting objects, and more. Ultrasonic sensors provide a non-contact sensing technique by measuring the time it takes for sound to travel to […]
How will sensors be used to increase warehouse automation?
Many of today’s warehouses have been or are in the process of transitioning from strictly a manual or conventional warehouse to a partially and eventually a fully automated warehouse. Depending on the level of sophistication, any automated process requires a variety of sensing technologies. Research from one company predicts that over 75% of companies will […]
What is normal blood pressure?
If you answered 120 over 80 mmHg, you are using criteria that is over 20 years old. As reported in a 2003 article, revised guidelines categorized normal blood pressure as <120/80 mmHg. Since the measurements are meant to lower the risks from not recognizing what is often called the silent killer – high blood pressure […]
How will NHTSA’s AEB mandate impact sensing?
In 2019, the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) published a draft pedestrian automatic emergency braking (PAEB) test procedure. When, the results of testing conducted in 2022 on 12 light vehicles were published in 2023 (2022 Light Vehicle Pedestrian Automatic Emergency Braking Test Summary, March 2023), one conclusion was: No vehicles […]
