Key takeaways

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

Reference excerpt

Invisible Fence Inc. (commonly referred to as Invisible Fence Brand) is a company that designs radio pet fences for cats and dogs. Manufactured and distributed by Radio System Corporation, the company sells wireless and fenceless systems that were first introduced in 1973. Its best-known product consists of an underground wire and a collar with an integrated transmitter that provides a signal to the pet when it approaches the perimeter.

History In the 1970s, traveling salesman Richard Peck worked as a sales and product manager for companies in Pennsylvania. His work took him from city to city, and as he drove through these towns, he noticed the number of dead pets lying along highways and city streets. He developed the idea of an "Invisible Fence". In 1973, he received a patent for the concept to build the first invisible fence. Peck formed a company called Stay-Put Sales Co. and marketed his product mainly through direct mail and magazines. In 1976, Peck sold the marketing and patent rights to John Purtell. Purtell created a company named Invisible Fence Co. In the 1980s, the receiver the dog wore around its neck was around the size of a cigarette packet. It suited larger dogs like Labradors and Huskies but not smaller animals like Chihuahuas without choking them. The product's range also only allowed a maximum of three acres of circle wire. Putrell pulled it from the market while the product was redeveloped to be smaller and needed a new battery only twice a year. Invisible Fence Co. lost exclusive rights to Peck's invention when the patent expired in 1990. As a result, many other companies emerged and designed their own version of the product including Radio System Corp, which currently owns the company. In 1993, John Purtell sold his interest in Invisible Fence. In 2001, IFCO and the Invisible Fence Brand were sold to Kohlberg & Company. Kohlberg and Company sold the company to Radio Systems Corp in 2006.

Project Breathe Its Project Breathe is an initiative created by the Invisible Fence Brand. The program donates animal oxygen mask kits to fire departments and first responders.

Worked examples

Example 1 — a first encounter with Invisible Fence Inc.

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

In research
Invisible Fence Inc. appears in engineering 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 Invisible Fence Inc. 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
Invisible Fence Inc. is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1973 establishments in Tennessee, American companies established in 1973, Animal training, so understanding it makes those chapters shorter.
In everyday life
Look for Invisible Fence Inc. 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.
