NOTIFIER’s ONYX Series intelligent fire alarm systems respond rapidly to incipient fire signatures with unmatched precision. At the same time, they significantly reduce the occurrence of nuisance alarms. It’s all made possible by NOTIFIER’s ONYX Advanced Detection technology, which maximizes speed, stability, and reliability. ONYX Advanced Detection is comprised of two key elements: a set [...]
Biblography makes it easy EndNote is useful software which gives you the capability to import references from online database and store them in your personal EndNote libraries. Some procedures of online reference databases expressly prohibit such use and storage of their data,othercharge an extra fee for alicence to use the data thisway. You can arrange [...]
Raman Amplifier: a)A fiber based Raman amp uses SRS occurring in silica fiber when an intense pump beam propagates through it b)The incident photon gives up its energy to create another photon of reduced energy and lower frequency c)This scattered wave is usually referred to as the Stokes wave Scgematic of Raman Amplifier (FIBER Based) [...]
In the optical devices, the condition of having enough excited or high-energy states distributed in a material that a chain-reaction of stimulated emission can occur. Lasers, for example, need a constant power source that maintains population inversion in order to generate radiation continuously, since each stimulated emission reduces the population of high-energy states
the resistor approach may be fine for some applications, I implemented a better solution for my 300KHz, +/-150V, 1000W half bridge application. A small gapped powdered iron core with a hall effect sensor stuck in the gap with a few windings (opposite directions)worked great and was cheap. Put this module in between the high & [...]
2010-12-20 – ABB’s robot-based surface finishing concept for wind turbine rotor blades reduces paint shop energy consumption by up to 60 percent and paint consumption by 25 percent compared to alternative methods of applying surface coatings. Most importantly, it provides a perfectly applied layer of protection for one of the most demanding operating environments on [...]
Siemens Industry, Inc., today announced that AdvanceBio Systems LLC, a Cincinnati-based technology company, selected Siemens Simatic S7-1200 controllers to automate its Bench Scale Hydrolyzer System. The Hydrolyzer System will be commissioned by The Pennsylvania State University for its Shared Fermentation Facility at University Park, Penn. “AdvanceBio Systems and The Pennsylvania State University intend to collaborate [...]
Embedded systems designers deserve better than the feature-lacking point-tools available today. Embedded designs should be more than a collection of microcontrollers and discrete components, pulled together by board design tools and software development environments that are not aware of each other presence, let alone integrated together. Programmable devices are not new. Embedded software is older [...]
Connect 230 volt single phase power to the T1 and T2 supply terminals (or wires) of the motor that you are using as a converter. Get it Spinning (with a rope wrapped around the motor shaft for example) to get it going – it won’t start on its own. Take 3 phase power off of [...]

MULTICOR® MASS FLOW METER CORIOLIS PRINCIPLE The Multicor® mass flow meter [...]
In a contact-less electronic angular-position transmitter having a turnable magnet (5), sensor coils (11, 12) arranged at right angles to each other are provided on a toroidal core (9), common to all sensor coils, of a magnetic-field detector formed in accordance with the flux-gate principle in order to determine the angular position. The angular-position transmitter [...]
