- Sensitivity enhancement of Passive Infrared (PIR) sensor for motion . . .
For the PIR sensor, coverage area, sensitivity, angle of view, and responsitivity are the main criteria required for better sensor performance The dominant one is the sensitivity, which is the measure of the change in output to unit change in input of the sensor
- Bifurcation analysis and control in a second-order DC–AC inverter with . . .
The quasi-PIR controlled second-order inverter has two working modes, and its state switches between mode one and two once in a switching period via the bipolar sinusoidal pulse width modulation
- Passive Infrared Sensor - an overview | ScienceDirect Topics
3 2 Passive infrared sensor (PIR sensor) A PIR sensor is an electronic sensor used in motion detectors such as automatically triggered lighting devices and protection systems that measure devices emitting infrared light in their field of view Each body with a temperature above zero releases heat energy, which is in the form of radiation
- Passive infrared sensor dataset and deep learning models for device . . .
For these reasons, PIR and thermopile sensors are also viable options for location estimation in an indoor environment such as home and office buildings There are a substantial number of papers that proposed passive infrared-based location estimation
- Role and mechanism of piR-0228 targeting RIPK1 to . . . - ScienceDirect
In addition, we identified and confirmed that RIPK1 is a downstream target of piR-0228 and is negatively regulated by it through the integration of bioinformatics analysis Finally, we demonstrated the protective effects of piR-0228 in vivo by constructing a mouse model of AD
- Mechanical and thermal properties of polyisocyanurate rigid foams . . .
The use of polyisocyanurate (PIR) foams as a substitute for polyurethane (PUR) is steadily growing for insulation, flooring, and roofing applications, given PIR's higher flammability performance [1, 2], low cost, and outstanding thermal insulation properties Polyisocyanurate molecular structure consists of highly crosslinked isocyanurate rings, which enhance thermal stability, flame
- Optimized Fresnel lens design for enhanced Passive infrared sensors in . . .
Optimized Fresnel lenses are integrated into next-generation systems like passive infrared (PIR) sensors, compact thermal imaging devices, and miniaturized security monitoring systems The model supports both circular and cylindrical symmetry, allowing for anisotropic optical designs adaptable to specific needs, such as motion detection or
- Review of signal processing applications of Pyroelectric Infrared (PIR . . .
