  AI Glass What Are AI Glasses? AI glasses are wearable devices like Xreal Air or Vuzix Blade that use augmented reality (AR) displays, cameras, AI processors, and voice interfaces to deliver contextual data. They process inputs via onboard AI (e.g., similar to GPT models) for object recognition, measurements, and simulations without needing a separate computer. Polytechnic students can use them affordably with apps like Google Lens or custom AR software for mechanical tasks. ​ Key Features for Mechanical Students Real-Time Measurements : Scan parts with built-in cameras for instant dimensions, tolerances, and 3D models—ideal for reverse engineering projects using tools like Geomagic or Fusion 360 integration. AR Overlays : Visualize CAD assemblies (e.g., SOLIDWORKS models) superimposed on physical prototypes, aiding assembly verification and stress analysis demos. AI Guidance : Voice-activated tutorials for CNC programming, 3D printing setups, or IoT sensor troubleshooting during ...

Turbochargers: Working Principle and Applications-(GRK)

Image
  Turbochargers: Working Principle and Applications 1. Introduction A turbocharger is a forced-induction device used in internal combustion engines to increase engine power and efficiency. It works by using waste exhaust gas energy to compress the intake air supplied to the engine. By supplying more air (oxygen) into the combustion chamber, more fuel can be burned, resulting in higher power output without increasing engine size . Turbochargers are widely used in automobiles, marine engines, aircraft engines, locomotives, and power plants . 2. Need for Turbocharging In naturally aspirated engines: Only atmospheric pressure fills the cylinder Power output is limited by air density Efficiency drops at high altitudes Turbocharging helps to: Increase engine power Improve fuel efficiency Reduce emissions Compensate for altitude losses Enable engine downsizing   3. Main Components of a Turbocharger 1. Turbine Located on the...
