Unique THz ‘Fingerprints’ Will Identify Hidden Explosives From A Distance
A major breakthrough in remote wave sensing by a team of Rensselaer Polytechnic Institute researchers opens the way for detecting hidden explosives, chemical, biological agents and illegal drugs from a distance of 20 meters. The new, all-optical system, using terahertz (THz) wave technology, has great potential for homeland security and military uses because it can “see through” clothing and …

Laser Printer Parts – What Are the Parts of a Laser Printer?
What are the parts of a laser printer? The main laser printer parts are located within the toner cartridge. There is an assembly of many components within the cartridge, and inside a series of chemical, electrical, and mechanical processes takes place. Parts include a primary charge roller or corona wire, photoconductor drum, laser, toner, fuser assembly with rollers, and discharge lamp. It is an electro photographic process which transfers digital information from a computer to images on paper in the laser printing process.
A primary charge roller, or a corona wire in older printers, projects an even electrostatic charge onto the surface of a photoconductor drum. A laser shines onto the photoconductor drum, and creates a chemical reaction. An electrostatic image is developed from discharging the areas that are negatively charged. The printer covers the rotating drum with toner creating text and images. The toner, which is fine particles of dry, plastic powder mixed with black or color, will stick to the places where the drum has an opposite charge and not to the places with the same charge. The letters and images are formed that will be printed on paper.
There is a fuser assembly with rollers which uses heat and pressure to make the ink permanent on the paper. The toner powder melts and fuses with the fibers on the paper making a finished page.
The drum passes a discharge lamp after the toner has been placed on the paper. This bright light erases the electrical image from the photoreceptor.

Laser Printers or Inkjet Printers? A Buyers Guide

Laser Printers or Inkjet Printers? A Buyers Guide
Should you buy an inkjet or a laser printer? Often people buying a new printer are confused about whether to buy a laser printer or inkjet printer. The short answer is it depends on what you’ll be using it for, and how much you’ll be using it.
Inkjet printers have a lower initial purchase cost but cost more to run because the ink is more expensive when measured on a per page basis. Laser printers cost more but their running costs are lower and they have a better print quality because in general they have a higher resolution (expressed in dots per inch – dpi).
If you want to print photos at home however, you are best to choose a photo quality inkjet printer.
Inkjets are great for home use and for photo printing. Lasers are good for high-volume applications, like offices, or for applications that need high print quality.
Inkjet printers transfer tiny droplets of ink directly to the page. A laser printer creates an electrostatic pattern on a drum that attracts ink powder that is subsequently fused onto the paper. This is more complex technology so means a higher price than for an inkjet printer.
If you examine the same page printed on both a laser printer and an inkjet, you will be able to see that the characters on the laser printer produced page are sharper. That said however, inkjet printers are getting better all the time in terms of the sharpness of printed characters.
Another aspect to consider is how heavily you will be using a printer. Printer manufacturers express the durability of a printer in terms of duty cycle in pages per month.
For example, a typical laser printer will be capable of a duty cycle up to 7,000 pages a month while a typical entry level inkjet printer is capable of up to 500 pages per month.
Some of the more recent inkjets provide excellent color clarity and brightness, and are very
