JVIS

JVIS is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand JVIS rather than just read about it. In short: JVIS is an automotive electronics and accessories supplier based in Michigan. Open Dots Open Dots is a conductive charging specification that was promoted by the Open Dots Alliance, a 501(c)(6) non-profit organization, which was formed by JVIS in 2015 and appears to be inactive since 2018.

Key takeaways

JVIS belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect JVIS to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of JVIS from memory before moving on to harder problems.

Reference excerpt

JVIS is an automotive electronics and accessories supplier based in Michigan.

Open Dots Open Dots is a conductive charging specification that was promoted by the Open Dots Alliance, a 501(c)(6) non-profit organization, which was formed by JVIS in 2015 and appears to be inactive since 2018. The technology has been available since 2009 in various JVIS products. An Open Dots receiver, which can be a phone case, has three contacts arranged 120 degrees apart on the circumference of a circle of one-centimeter (two-fifths of an inch) radius, and a fourth contact at its center. An Open Dots charger, typically a charging pad, is a surface with a series of two or more approximately centimeter-wide strip-shaped contacts, spaced apart so an individual contact dot on the receiver cannot touch two pad contacts simultaneously. Adjacent rows of charging pad contacts have alternating polarities. When the surface of the receiver is placed on the surface of an Open Dots charging pad, the contacts are spaced such that the array of receiver contacts is always spanning a pair of charger contacts. The system can thus form an electrical circuit in any angular orientation, allowing the user to simply place their device on a charging pad to start charging. In May 2015, the alliance stated that the Open Dots standard was adapted for use in 12 vehicle models across five major automotive brands – Ford, Chrysler, RAM, Dodge, and Scion. Phone case maker Incipio was mentioned as making compatible products.

Worked examples

Example 1 — a first encounter with JVIS

Start with the simplest possible case. Write down what JVIS claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 JVIS 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 JVIS 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 JVIS

In research: JVIS appears in 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 JVIS 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: JVIS is common in secondary-school and first-year university syllabi. It links to neighbouring topics Mobile telecommunications user equipment, so understanding it makes those chapters shorter.
In everyday life: Look for JVIS 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.

Frequently asked questions

What is JVIS in simple terms?

JVIS is an automotive electronics and accessories supplier based in Michigan. Open Dots Open Dots is a conductive charging specification that was promoted by the Open Dots Alliance, a 501(c)(6) non-profit organization, which was formed by JVIS in 2015 and appears to be inactive since 2018.

Why does JVIS matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study JVIS?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
