Mercury (toy manufacturer): Mercury was a brand of diecast toy cars manufactured in Italy from about 1945 through the 1970s.  Along with Dinky Toys in England, Mercury was a pioneer in 1:43 scale diecast toys made in Europe.  Today, Mercury models are rather rare and not easy to find.  The company logo was the word Mercury within a rectangle with a round toothed gear behind the company name.

Edison Assembly: Edison Assembly, also known as Metuchen Assembly, was a Ford Motor Company manufacturing plant in Edison, New Jersey.  It was located at 939 U.S. Route 1 and occupied over 100 acres when it was open.  The factory began operations in 1948 and was closed in 2004.  Several popular Ford products were manufactured there, such as the Ford Mustang, Ford Ranger, and the Ford Pinto.  When the plant opened in 1948, it manufactured the new Mercury branded and Lincoln vehicles.  It was one of three Ford manufacturing facilities in New Jersey and was built two years before the Mahwah Assembly plant was opened in 1950.

Mazda Familia: The Mazda Familia, also marketed prominently as the Mazda 323 and Mazda Protegé, was a small family car that was manufactured by Mazda between 1963 and 2003.  The Familia line was replaced by the Mazda3/Axela for 2004.

7th Level: 7th Level was a video game development company based in Dallas, Texas and founded in 1993.  The company was most famous for developing the three Monty Python games (with the aid of Python member Eric Idle), "G-Nome" (1997) — a "MechWarrior"-style game, for publishing "Helicops" (1997) — an anime-inspired arcade-style aerial combat game, and for "Tracer" — a game of hacking distributed computer systems for cash using a virtual avatar in the design of "Neuromancer", "Shadowrun", or "Snowcrash" styled virtual worlds.

Crayford Engineering: Crayford Engineering (more commonly known simply as Crayford) was an automobile coachbuilder based in Westerham, Kent, England and formed in 1962 by Jeffrey Smith (engineer and designer) and David McMullan MBE (sales).  In the 1970s, a subdivision within the company, called Crayford Auto Developments, Ltd., was established for automobiles.  The company specialized in converting European coupés and saloons into convertibles and estates.  Notable products included the convertible Mini, BMC 1100/1300 convertible, convertible Corsair, Cabriolet Corsair, Cabriolet Capri, the rare Triumph TR7 Tracer Estate, and a Princess hatchback conversion, a commonly accepted principle for a car that appeared to be, but was not, a hatchback to begin with.  Other lesser-known conversions from Crayford included the Tempest, a convertible Volkswagen Scirocco, a Ford Cortina Mk V Convertible, and a Mercedes S-Class Estate.  The cars designed and created by Jeffrey Smith were featured in the Olympic Closing Ceremony in London 2012.

Mercury Lynx: The Mercury Lynx is a compact car that was produced by Mercury for model years 1981 to 1987.  It was a rebadged version of the Ford Escort.  In 1987, the Lynx was dropped after slumping sales (although at one point, it was Mercury's best-selling car).  In 1988, Mercury launched the Tracer as the Lynx's replacement.  The Tracer was based on the Mazda 323, was built in Mexico and Japan (depending on model), and shared nothing with the Lynx.

Rechargeable alkaline battery: A rechargeable alkaline battery (also known as alkaline rechargeable or rechargeable alkaline manganese (RAM)) is a type of alkaline battery that is capable of recharging for repeated use.  The first generation rechargeable alkaline batteries were introduced by Union Carbide and Mallory in early 1970's.  Several patents were introduced after Union Carbide's product discontinuation and eventually, in 1986, Battery Technologies Inc of Canada was founded to commercially develop a 2nd generation product based on those patents.  Their first product to be licensed out and sold commercially was to Rayovac under the trademark "Renewal".  The next year, "Pure Energy" batteries were released by Pure Energy.  After reformulating the Renewals to be mercury free in 1995, subsequent licensed RAM alkalines were mercury free and included ALCAVA, AccuCell, Grandcell and EnviroCell.  Subsequent patent and advancements in technology have been introduced.  The formats include AAA, AA, C, D, and snap-on 9-volt batteries.  Rechargeable alkaline batteries are manufactured fully charged and have the ability to hold their charge for years, longer than NiCd and NiMH batteries, which self-discharge.

Atlas LV-3B: The Atlas LV-3B, Atlas D Mercury Launch Vehicle or Mercury-Atlas Launch Vehicle, was a man-rated expendable launch system used as part of the United States Project Mercury to send astronauts into low Earth orbit.

All three generations of the Tracer were based on variations of the Mazda 323/Protegé.

Avid Radiopharmaceuticals: Avid Radiopharmaceuticals is an American company, founded by Dr. Daniel Skovronsky, and based at the University City Science Center research campus in Philadelphia, Pennsylvania.  The company has developed a radioactive tracer called florbetapir (F).  Florbetapir can be used to detect beta amyloid plaques in patients with memory problems using positron emission tomography (PET) scans, making the company the first to bring to market an FDA-approved method that can directly detect this hallmark pathology of Alzheimer's disease.  Venture investors include Alta Partners, Osage University Partners, and Safeguard Scientifics.
