Study Notes

3D Scanning Technology

3D scanners create 3D images of solid objects for use in CAD software or 3D printing.
Technologies include lasers, X-rays, magnetic resonance, and white light.
Used in medical applications for tomography, producing sliced images of human anatomy.

Tomography and Imaging Techniques

Tomography involves slicing objects to create 3D images, primarily using X-rays.
MRI scanners utilize radio frequencies for non-invasive imaging.

Touchscreen Technology

Common input devices in various settings, including fast food ordering and information kiosks.
Support input through bare fingers or special styluses.
Three main touchscreen technologies: capacitive, infrared, and resistive.

Printers and Printing Technologies

Inkjet printers are suitable for small print runs like photographs or a few pages.
Laser printers utilize dry powder ink (toner) and are efficient for large print jobs, producing text/images in one go.
Laser printers employ a negatively charged drum that interacts with positively charged toner to transfer images onto paper.

3D Printing Applications

3D printers produce functional solid objects, utilizing technology akin to inkjet and laser printers.

Level Sensors and Monitoring

Different technologies (ultrasonics, capacitance, conductivity) are used to monitor levels in various applications like tank levels or tablet production.
Additional types of level sensors include optical and mechanical sensors.

Control Systems with Sensors and Actuators

In chemical processes, sensors monitor and manage parameters like temperature and pH.
Actuators adjust conditions by controlling heating elements and valves to maintain desired chemical reactions.
