Barcode scanners

A barcode scanner (or barcode reader) is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode scanners contain decoder circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.

Barcode scanners of all stripes have decreased in cost. Current pricing of mid-grade retail / industial barcode scanners is in the $200 range for a unit with a stand and 5-year guarante.In the simplest implementations, the wired barcode scanner is all that's required to begin reaping the increased speed and accuracy of scanning barcodes. In all retail and most industrial environments product barcodes can be found on products shipped in from vendors. Most companies have some sort of computer software that required the operator to enter the UPC or SKU number into the system, which a corded scanner can accomplish out of the box without set-up.

Espresso

If you go to a espresso or cafe bar and ask for an espresso, you will get a shot-sized glass holding a small amount of very strong coffee. There are many different types of espresso drinks including cafe mocha, cafe latte and cappuccino and all are made with one or more shots of espresso. The shot of espresso is made by forcing about 40 grams of boiling water through finely ground, tightly packed espresso coffee. If everything goes well, what comes out is a slightly thick, dark brown, liquid with a small amount of crema (a foam, sort of like the head on a beer) on top.

There are many variables in the process of making a shot of espresso. The pressure of the water, the temperature of the water, the fineness of the ground coffee and how tightly the coffee is packed are just a few. The skilled espresso maker, or barista, controls all of these variables to produce a quality shot of espresso.
