High-performance RF bandpass filters may hold the key to autonomous vehicle communication without interference. Ali Bawangaonwala | Qorvo, Inc. Continuing advances in technology are making the autonomous vehicle a practical reality, and there is frequent discussion among technologists about Wi-Fi and 5G as enablers of the connected car. Equally important, but less talked about, are […]

How GMR wheel speed sensors help advance vehicle control and braking systems
Giant magnetoresistance sensors are strong candidates for the high-accuracy wheel-speed sensing necessary in autonomous vehicle systems. Christine Graham | Allegro MicroSystems The purpose of a braking system has evolved from simplistic stopping to critical functions in vehicle safety through highly accurate feedback to traction control (TCS) and advanced driver assistance systems (ADAS). These advances have […]
Validating correct behavior in ADAS and AV systems
Autonomous vehicles must operate in a world of uncertainties. Validation platforms are now capable of determining whether behavior is correct given complex contextual attributes. David Fritz, Mentor, A Siemens Business There is an interesting dashcam video circulating in the autonomous vehicle (AV) development community of a Tesla-paid test driver coming up on what the driver […]
V2Clueless – Next generation of connected apps?
Leland teschler Executive Editor If you had been watching the Saturday Night Live TV show in mid-January of 2012, you would have seen a skit called the Headz Up App. It was an ad for a fictional app aimed at people so distracted by texting on their smartphone that they were prone to walking cluelessly […]
The working principle, applications and limitations of ultrasonic sensors
The ultrasonic sensor (or transducer) works on the same principles as a radar system. An ultrasonic sensor can convert electrical energy into acoustic waves and vice versa. The acoustic wave signal is an ultrasonic wave traveling at a frequency above 18kHz. The famous HC SR04 ultrasonic sensor generates ultrasonic waves at 40kHz frequency. Typically, a […]
Embedded security: Do you know what you don’t know?
by Lynnette Reese, contributing editor Most of us assume that security comes from the operating system or application software. However, firmware is also at risk, including anything that barely hovers over the physical layer (silicon) in the chip. Embedded security is especially important in blocking seemingly innocuous pathways for hacking, such as in an automotive […]
The role of sensors in IoT networks, Part 2: Smart sensors and how to choose
Part 2 of this series continues with answering common questions about how sensors work in IoT system development. What are smart sensors? Basic sensors can detect changes in their environments and convert measured data into a digital format for the external microcontroller to process. The “smart” is in the microcontroller. Combining the microcontrollers in a […]
What are the roles of sensors in an IoT network? Part 1
The Internet of Things (IoT) and edge computing have created many smart industries such as smart city, smart factories, smart agriculture, smart medicine, and more. How do they become smart? The key lies in real-time data capture and analytics, using various types of sensors. TechJury, a software firm that reviews forecasts from various companies, predicts […]

Beyond Moore’s Law: New solutions for beating the data growth curve
By Daniel Joseph Barry, VP Strategy and Market Development, Napatech Many of the latest innovations in cloud, enterprise, and telecom networks are predicated on the assumption that the power of server CPUs will continue to grow in line with Moore’s Law. This law predicts that the number of transistors per square inch will double every […]
