Abstract: This brief presents the analog circuit of a simplified Tent map and its applications in sensor position optimization. The experimental results of the circuit are consistent with the ...

Can a handful of transistors outperform a microcontroller? This acoustic sensor delivers reliable, fail-safe sound detection and shows how elegant analog design can still solve real-world problems.

This design based on an SR latch and two RC networks is, unlike many alternative solutions, neither complex nor expensive. Single and differential capacitance sensors are widely used to measure linear ...

Let’s face it: As we age, our vision and balance aren’t what they used to be. These changes to our senses can be minor annoyances but can also lead to injury, from stubbed toes to serious falls.

An improved passive wireless sensor is presented for ultra-high temperature environments, utilizing a folded Complementary Split-Ring Resonator (CSRR) structure. A dedicated back-end circuit ...

I live in New Jersey, one of the states that mandates inspection for all vehicles newer than 1995. My daily driver, a Jeep Cherokee, happens to be a 1996 model year with an OBD-II sensor, meaning I ...

There are many different trouble codes that can be set in the system when there’s an issue with an oxygen sensor. One such example is the P0133 code. What does it mean and how does it differ from ...

The long-running legal saga between Apple and Masimo over the Apple Watch’s blood oxygen sensor has reached a critical new phase. Earlier this week, Apple took its case to the US Court of Appeals for ...

Sensors monitoring mechanical and biological systems must often scavenge power from the thing being sensed. The oscillator circuits shown here let you operate those sensors. Sensor circuits that ...
