Because the original designer had left the company another employee completely redesigned most of the system, ( adding a display snow remover circuit, true 80 / 64 column text mode support, ( with different size letters for TRS-80 and CP / M mode, so that in TRS-80 mode the full screen was also used, not just a 64x16 portion of the 80x25 screen ) with an improved font set ( adding " gray scale " version of the TRS-80 mozaik graphics and many special PETSCII like characters ), and a more flexible and reliable floppy disk controller and keyboard interface plus many other small improvements ), also an enclosure was developed for the main computer system, ( in the form of a 19-inch rack for the Eurocards ) and for two floppy disk drives and the power supply.

The various styles continued expanding well into the 19th and 20th centuries, proportional to the influx of immigrants from many foreign nations ; such influx developed a rich diversity in food preparation throughout the country.

As early American Indians lacked the proper pottery that could be used directly over a fire, they developed a technique which has caused many anthropologists to call them " Stone Boilers ".

Training in conservation for many years took the form of an apprenticeship, whereby an apprentice slowly developed the necessary skills to undertake their job.

" Activists point to the unequal footing and power between developed and developing nations within the WTO and with respect to global trade, most specifically in relation to the protectionist policies towards agriculture enacted in many developed countries.

These activists also point out that heavy subsidization of developed nations ' agriculture and the aggressive use of export subsidies by some developed nations to make their agricultural products more attractive on the international market are major causes of declines in the agricultural sectors of many developing nations.

Rózsa Péter and Raphael Robinson later developed a two-variable version of the Ackermann function that became preferred by many authors.

There were many successful commercial BBS programs developed for DOS, such as PCBoard BBS, RemoteAccess BBS, and Wildcat!

There were several dozen other BBS programs developed over the DOS era, and many were released under the shareware concept, while some were released as freeware including iniquity.

The simplest way to gain information about brain anatomy is by visual inspection, but many more sophisticated techniques have been developed.

Originally developed by Ericsson, Bluetooth technology is now used in many different products by many different manufacturers.

More complex assistive technology devices have been developed over time, and as a result, sports for people with disabilities " have changed from being a clinical therapeutic tool to an increasingly competition-oriented activity ".

A thriving 3rd party market for AppleTalk devices developed over the next few years.

Initial field ion microscopes, precursors to modern atom probes, were usually glass blown devices developed by individual research laboratories.

Pocket sized devices became available in the 1970s, especially after the invention of the microprocessor developed by Intel for the Japanese calculator company Busicom.

Later, in post war years, as consumer devices began to be developed, the field grew to include modern television, audio systems, computers and microprocessors.

This area is largely dominated by thermoelectric ( TE ) devices, though thermionic ( TI ) and thermophotovoltaic ( TPV ) systems have been developed as well.

Like many other devices that were more fully developed in Europe during the next decade, what could be called the " atmospheric insert shot " made its first appearance in American films during the years before 1919.

The general trend in the development of cinema, led from the United States, was towards using the newly developed specifically filmic devices for expression of the narrative content of film stories, and combining this with the standard dramatic structures already in use in commercial theatre.

The field-effect transistor was first patented by Julius Edgar Lilienfeld in 1925 and by Oskar Heil in 1934, but practical semi-conducting devices ( the JFET ) were only developed much later after the transistor effect was observed and explained by the team of William Shockley at Bell Labs in 1947.

Ion implantation was developed as a method of producing the p-n junction of photovoltaic devices in the late 1970s and early 1980s, along with the use of pulsed-electron beam for rapid annealing, although it has not to date been used for commercial production.

Because the microwave predecessor of the laser, the maser, was developed first, devices of this sort operating at microwave and radio frequencies are referred to as " masers " rather than " microwave lasers " or " radio lasers ".

Currently microphotonics technology is being developed to replace electronics devices.

Contemporary media studies includes the analysis of new media with emphasis on the internet, video games, mobile devices, interactive television, and other forms of mass media which developed from the 1990s.

In vivo imaging is another area where tools and devices are being developed.

While the most common pointing device by far is the mouse, many more devices have been developed.

The first practical application for piezoelectric devices was sonar, first developed during World War I.

This lab developed many innovations, such as color television, the electron microscope, CMOS-based technology, heterojunction physics, optoelectronic emitting devices, liquid crystal displays ( LCDs ), videocassette recorders, direct broadcast television, direct broadcast satellite systems and high-definition television.

In dynamic random access memory ( DRAM ) devices, storage capacitors are also fabricated at this time, typically stacked above the access transistor ( implementing them as trenches etched deep into the silicon surface was a technique developed by the now defunct DRAM manufacturer Qimonda ).

The teleostereograph machine, a forerunner to the modern electronic fax, was developed by AT & T's Bell Labs in the 1920s ; however, the first commercial use of image facsimile telegraph devices dates back to the time of Samuel F. B. Morse's invention in the 1800s.

These devices were developed by several European scientists in the 16th and 17th centuries, notably Galileo Galilei.

Universal Serial Bus ( USB ) is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication and power supply between computers and electronic devices.

However, tubes still find uses where solid-state devices have not been developed, are impractical, or where a tube has superior performance, as with some devices in professional audio and high-power radio transmitters.

Fluid layouts developed around 2000 as a replacement for HTML-table-based layouts, as a rejection of grid-based design both as a design principle, and as a coding technique, but were very slow to be adopted .< ref group =" note " >- based markup and spacer.
