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. PIR sensors detect infrared radiation that is reflected ...
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.
The article reviews signal processing applications of Pyroelectric Infrared (PIR) sensors with the main focus on the respiration and pulse rate detect…
This study identified piR-hsa-35410 (hereafter piR-35410) with aberrant expression and aimed to further elucidate its biological functions and mechanisms in TNBC. In TNBC, the elevated expression of piR-35410 enhanced clone formation and cell migration capacities, as well as glycolytic activity.
This research aims to design and implement a home security system with the capability for human detection. The traditional home security system, i.e. …
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 ...
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.
Our data suggest that Pira is a potential target to induce long-term allograft tolerance. CD40 may activate transcription factor NF-κB2 translocation into the nucleus to up-regulate PIR-A expression, promoting chronic rejection of cardiac transplantation. The study findings provide novel therapeutic opportunities to promote transplant survival in clinical settings.
Here, we identified Pirin (PIR) as a key oncogenic factor in UM through comprehensive multi-omics analyses, revealing that PIR is significantly upregulated and correlates with poor prognosis. Functional assays indicated that inhibiting PIR markedly suppressed UM progression, highlighting its critical role in tumorigenesis behavior.
The sensors divided the office into six separate sub-zones. The four west PIR sensors covered four seats and the personnel sitting in these positions were all university researchers, whereas the two east PIR sensors recorded the occupancy conditions of the two meeting areas. The PIR sensors cover 180° in directions.
