When you hear the name James Dyson you may recall his famous Dyson cyclonic vacuum that came on the market a few years ago. What do you think his next invention will be? Developing new products and managing them through the first several stages of the product life cycle can be a difficult and risky task. Inventor James Dyson learned how to manage an effective product life cycle through trial and error. His experiences have led him to believe that the time has come for an “effective and environmentally

endotracheal tube you will prefer RAE‚ flexomettalic or mcintosh? What are the problems associated with these tubes? Ans- Ideal ET Tube is south facing RAE (Ring Adair Elwin) tube fixed in center over the lower lip. RAE Endotracheal Tubes are designed to conveniently position the anesthesia circuit out of the surgical field. Problem- Difficult to pass Suction catheter. Fixed curvature hence more chances of endobronchial intubation or inadvertent extubation. Flexometallic tubes- Inner diameter of tube decreases

This was solved with a rectifying vacuum tube‚ invented by John Ambrose Fleming. The vacuum tube was added a new component to become an amplifying vacuum tube. Lee De Forest who was an American‚ invented this amplifying vacuum tube by adding a third electrode‚ called a grid. The grid’s negative potential controlled the flow of electrons from the cathode to the anode. The lower the negative potential of the grid‚ the more electrons it allowed to flow through the tube‚ hence producing an amplified current

1. First Generation (1944-1959) Vacuum tube as a signal amplifier‚ it was a typical first-generation computer. Initially‚ vacuum tubes (vacuum-tube) are used as a component of the signal amplifier. Raw materials consist of glass‚ so much has disadvantages‚ such as: easily broken‚ and easy to distribute the heat. This heat needs to be neutralized by other components that serve as a coolant. And with the additional component‚ the computer finally appeared to be a big‚ heavy and expensive. In 1946

Vacuum is produced by the engine’s piston drawing air from the intake manifold during it’s down stroke. The throttle plate keeps air from freely flowing into the manifold creating manifold vacuum. When the throttle body is opened there’s a collapse or loss of vacuum. This collapse in vacuum is actually an increase in intake manifold air pressure. Vacuum is measured in inches of mercury (in. Hg). A quick snap of the throttle plate should drop the vacuum to around 5 in. Hg (inches of mercury)‚ and

Op-Amp) Introduction History: The audio amplifier was invented in 1909 by Lee De Forest when he invented the triode vacuum tube. The triode was a three terminal device with a control grid that can modulate the flow of electrons from the filament to the plate. The triode vacuum amplifier was used to make the first AM radio.[2] Early audio power amplifiers were based on vacuum tubes (also known as valves)‚ and some of these achieved notably high quality (e.g.‚ the Williamson amplifier of 1947-9).
