Why Dyson created the Dyson Vacuum Cleaner

Dyson Vacuum CleanersTo understand what James Dyson set out to change in 1978 with his Dyson Vacuum Cleaner we need to go all the way back to 1901. That’s when another English Inventor, by the name of Hubert Cecil Booth invented the first one.

By today’s standards that cleaner certainly does not qualify as the best vacuum for carpet or any other surface.

Admittedly at that time most houses had hard wood floors and rugs, not the wall to wall carpets popular today

 

Modern vacuum cleaners don’t actually work by creating a vacuum at all, and neither did the early ones. More accurately the machine that Booth invented was designed to suck up and filter air. No actual vacuum involved.

The Basic of Computer Font – An Overview

font

Computer font which is often referred as “font” is primarily an electronic data file that consist a set of glyph which is the element of writing, characters, and symbols like dingbats. At present there are three basic types of computer font – they are Bitmap, Outline and Stroke.

The 3 types of font we used in computer codes – Advantages and Disadvantages

Bitmap Fonts

Bitmap fonts are not scalable and flexible as it requires separate size of each font but they are much easier to incorporate in computer code. It will store every glyph as an array of pixels making it easy to render. The one advantage of bitmap fonts is that it is easier to create than the other two kinds of font. It will give the same exact outputs.

However, the disadvantage of this font is that the visual quality is poor when we alter the size. As mention bitmap fonts are not scalable and when scaled or transformed it produces poor visual quality.

The bitmap fonts were exclusively used with earlier computers because of their limited processing power and memory. This is however not the case anymore and Outline and Stroke are becoming more popular with modern computers because of their flexibility. Yet, bitmap fonts will be creating a high quality visual font when presented at their original pixel size.

Outline Fonts

Outline Fonts are also known as “Vector Fonts”, they are a collection of Vector images. This refers to the set of lines and curves it uses to define glyphs. This font became famous with the introduction of desktop publishing. The need for integrating graphic user interface with supporting devices as a universal standard became even more important. This is commonly known as What You See Is What You Get (WYSIWYG).

The advantage of Outline Fonts is that it is scalable without pixellation or disoriented of the font. This is done my applying a mathematical function to scale fonts to the desired size. The beauty of this font is that it is scalable to any desired size provided the right processing and software.

The disadvantage of Outline fonts is that it can’t be rendered accurately onto computer screens and printers. It will need refined software particularly to implement visual correctly. Modern computers are equipped to tackle Outline fonts but they will need much more processing power as compared to bitmap fonts.

Stroke Fonts

Similar to outline fonts, Stroke based fonts are defined by the verticals of individual stokes as the name suggest. But it requires fewer strokes as compared to outline fonts to define a glyph and considered an advantage. It is easier to edit a glyph with stroke fonts for developers and because developers makes less strokes to define a glyph they will makes less error. Developers in East Asian countries are dependent of stroke fonts and it is heavily marketed for this market.

All the three types of fonts are still in use but the most popular one is the outline fonts. Outline fonts are popular with modern computers. Also note that fonts specifically designed for computer screen and not printing are called screen fonts.
