A process and system for flame detection includes a microprocessor-controlled detector with an array of sensors for sensing radiant energy from a fire or other heat source. A wide band infrared sensor is used as
A flame monitor method and system where one pair or more of radiation sensors respond to high frequency radiation fluctuations in regions of the same flame or different flames, with each sensor producing an electrical signal indicative of the flame condition. The electrical signals developed by the...
The average of the data of each sensor for 50–55 s were used to draw Fig. 13, with the sensor height as the independent variable. In Fig. 13, the first set of data shows the characteristics of exponential decline, and the R2 value is higher than 0.98. The difference between ...
Over the decades, a myriad of surfaces with unique wetting properties have been developed1,2,3, including lotus-effect superhydrophobic surfaces1,2,4, petal-effect surfaces with controllable droplet adhesion5,6, superomniphobic surfaces that can repel both water and oil7,8,9, antifouling lubricated...

engine performance, attributed to methane's higher flame speed, which subsequently minimized cyclic variation. However, the storage requirements of methane and hydrogen—necessitating high-pressure containment in a liquid state contrast sharply with ammonia's ability to liquefy under moderate pressures of ...

our sensor platform demonstrated to be capable of detecting multiple variants of the SARS CoV-2 virus. Such proof of concept was achieved both in buffer and serum, with the developed sensor being able to distinguish between SARS CoV-2 and otherhuman coronaviruses. Additionally, the LSPR substrate...
A detector system having multiple sensors, each sensor detecting a different danger condition, has an address comparator for determining whether an access address coincident with a selected address is present in an access signal received from a central monitoring unit. The detector exchanges an informat...
A further object according to the present invention is to provide a control system capable of using a standalone or system operable modular flame sensor, the flame sensor being capable of functioning with flame rod and/or ultraviolet flame transducers, such that the processor of the system control...
