Reference excerpt

IGB Eletrônica S.A. (Portuguese for IGB Electronics), doing business as Gradiente, is a Brazilian consumer electronics company based in Manaus, and with offices in São Paulo. The company designs and markets many product lines, including video (e.g. televisions, DVD players), audio, home theater, high end acoustics, office and mobile stereo for the Brazilian market.

History The company was founded in 1964. Between 1985 and 1990 they sold the Gradiente Expert line of MSX compatible home computers. In 1993 they founded Playtronic, a fully owned subsidiary that licensed the manufacturing of Nintendo consoles in Brazil, and while publishing games for various systems they also provided Portuguese translations of some games (among them, South Park and Shadow Man for the Nintendo 64). However, they stopped the partnership with Nintendo in 2003 because of the high price of the dollar at the time. In 1997, Gradiente established a joint venture with Finland-based telecommunications manufacturing firm Nokia, where they were granted the license to manufacture variants of Nokia mobile phones locally under the Nokia and Gradiente brand names.

iPhone trademark conflict In 2000, Gradiente, now legally known as IGB Eletrônica SA, filed for the brand name "iphone" in Brazil's INPI (National Institute of Industrial Property, the trademark authority). Gradiente first used the iPhone brand on a licence-built variant of the Nokia 7160, but it was not until 2008 when the Brazilian government granted full brand ownership for Gradiente, and the company has since sold Android-based smartphones under this name. Until 2008 that trademark was fully owned by IGB Eletrônica SA, which released its Android-powered iphone neo one under the Gradiente brand. The iphone neo one is sold for R$ 599 (about US$287), a dual-SIM handset running Android 2.3.4 Gingerbread. It has a 3.7-inch, 320 x 480 display, a 700 MHz CPU, 2GB of expandable storage, Bluetooth, 3G, WiFi and 5 / 0.3-megapixel camera.

Worked examples

Example 1 — a first encounter with IGB Eletrônica

Start with the simplest possible case. Write down what IGB Eletrônica claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to IGB Eletrônica before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about IGB Eletrônica ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of IGB Eletrônica

In research: IGB Eletrônica appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses IGB Eletrônica in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: IGB Eletrônica is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1964 establishments in Brazil, Audio equipment manufacturers of Brazil, Brazilian brands, so understanding it makes those chapters shorter.
In everyday life: Look for IGB Eletrônica outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
