PSC Inc.

PSC Inc. is a computer 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 PSC Inc. rather than just read about it. In short: PSC Inc. was a manufacturer of portable data terminals, mobile data terminals, wireless terminals, barcode readers, linear barcode verifiers, and RFID readers. It was founded in 1969 by John E.

Key takeaways

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

Reference excerpt

PSC Inc. was a manufacturer of portable data terminals, mobile data terminals, wireless terminals, barcode readers, linear barcode verifiers, and RFID readers. It was founded in 1969 by John E. Blackert (Xerox) and Lawrence P. Albertson (Kodak) as Photographic Sciences Corporation in Webster, New York (a suburb of Rochester).

History In 1996, PSC acquired Spectra-Physics Scanning Systems, Inc., and also acquired Percon Inc., a manufacturer of portable data terminals. In 2002, PSC went through bankruptcy reorganization. Littlejohn & Co., a private equity firm, purchased all of the company's senior and subordinated debt of $124 million. During the reorganization PSC spun off its software division, IntelliTrack to private investors.

Acquisition by Datalogic On October 24, 2005, Datalogic announced that it had signed a binding contract for the takeover of the entire capital stock of PSC Inc. The agreed price was set at approximately $195 Million. Datalogic retired the PSC brand name on April 2, 2007. The PSC legacy was catered to in the new corporate logo of Datalogic by adding a star representing PSC. Datalogic decided to retain some of the PSC product brand names including Magellan, Duet, Falcon, PowerScan, and QuickScan.

Worked examples

Example 1 — a first encounter with PSC Inc.

Start with the simplest possible case. Write down what PSC Inc. 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 PSC 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 PSC 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 PSC Inc.

In research: PSC Inc. 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 PSC 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: PSC Inc. is common in secondary-school and first-year university syllabi. It links to neighbouring topics Defunct computer companies of the United States, Defunct computer hardware companies, Radio-frequency identification, so understanding it makes those chapters shorter.
In everyday life: Look for PSC 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.
