Bio-reactors are said to be the cooking pots of bio-technologists and biochemists, in which pharmaceutical agents, nematodes or enzymes are made for the purpose of biological pest control. A nutrient solution (such as oxygen, heat, acid or alkali) is used to control the pH value and the preferred product is formed.
Leviton has reported a key technological advancement for monitoring commercial refrigeration equipment and preserving food safety in retail beverage and food operations.
A whisper can be heard in St. Paul's Cathedral, at London, from far across the circular whispering gallery as the sound curves around the walls. An optical whispering gallery mode resonator has presently been developed by Penn State electrical engineers.
Two teams of scientists from NASA are working install a highly compact, sensitive thermometer with the ability to characterize comets and also help in redirecting or probably destroying an asteroid on the course of a collision with Earth.
The cooler temperatures and brightly colored leaves will tempt people to venture into the great outdoors this fall. While packing their gears to find a close by hiking trail and setting out to explore new terrain, Casio America, Inc. now reminds outdoor adventurers to use a PRO TREK timepiece.
If a person standing outdoors is asked to report how many clouds passed overhead in the last one hour, he/she would only be able to provide a good estimate of the cloud coverage in that particular location. It certainly would not be fully accurate because of subjective human judgment (is this a cloud?) and it would not certainly be illustrative of the coverage in the larger surrounding area.
Torino Power Solutions Inc., is pleased to announce that it has begun developing a new distribution temperature sensor that will focus on lower voltage overhead “distribution” cables that we typically find in urban areas.
ROHM Semiconductor has proposed a modular solution for detecting machine failures in advance by integrating pressure, temperature, color, and other sensors that cover mechanical, environmental, and optical abnormalities.
Distributed sensors are increasingly used these days to regularly monitor the structural health of large structures such as bridges or dams. A newly developed fiber optic distributed sensor, with 1 million sensing points, will be able to detect structural problems in a much faster manner compared to those that are currently available.
It is essential to regularly check for defects, such as cracks, in technical systems. Till date, piezo sensors measuring pressure, voltage or force have been used to consistently detect such faults, but only to around 200 oC. Now, components that are as hot as 900 oC can be continuously monitored by special high-temperature piezo sensors.
