Hector's clingfish: Hector's clingfish, "Gastroscyphus hectoris", is a clingfish of the family Gobiesocidae, the only species in the genus Gastrocyathus.  It is found all down the east coast of New Zealand around the low water mark amongst seaweed, on rocky coastlines.  Its length is up to 6.4 cm SL.  It is named after Scottish-born scientist James Hector.

Oki Kibatarō: Oki Kibatarō (沖 牙太郎 , 1848–1906) was an engineer formerly employed at a Japanese Ministry of Industry ("Kōbushō") factory.  In 1877, only a year after Alexander Graham Bell's invention, "Kōbushō" had started an effort to make telephone receivers by reverse engineering and Oki was in the team that came up with the first prototype.

Scoubidou (tool): A Scoubidou is a corkscrew-like tool that is used for the commercial harvesting of seaweed, whose invention is credited to Yves Colin in 1961.  The device consists of an iron hook attached to a hydraulic arm.  It superseded a common harvesting tool known as the guillotine shortly after its invention.  The scoubidou is used primarily for harvesting "Laminaria digitata", a species used mainly for fertiliser.

Hemacite: Hemacite is a material made from sawdust and the blood of slaughtered animals cattle and pig.  It was invented (and patented) by Dr W H Dibble of New Jersey in the last quarter of the nineteenth century.  Hydraulic pressure (40,000 psi) and chemical compounds, blood and sawdust were transformed by Dibble's Hemacite Manufacturing Company into everything from doorknobs and roller skate wheels to cash register buttons and telephone receivers; there is even extensive use in Victorian jewellery.  Hemacite was inexpensive but fell out of favor with the popularity of new plastics like Bakelite, it is quite easy to misidentify Hemacite with Bakelite.

ARQ (film): ARQ is a 2016 American-Canadian science fiction film directed by Tony Elliott.  It was selected to be screened in the Discovery section at the 2016 Toronto International Film Festival.  The film was released on Netflix worldwide on September 16, 2016.  Robbie Amell plays an engineer whose invention causes time to loop during a home invasion.  He attempts to save his former lover, played by Rachael Taylor, while learning who has targeted him and why.

The Stolen Invention: The Stolen Invention is a 1910 American silent short drama produced by the Thanhouser Company.  The film focuses on John Deering, an inventor, whose invention interests Mr. Cobleigh.  Deering rejects the small sum Cobleigh offers for the invention, so Cobleigh decides to drugs Deering.  The effect of the drug makes him temporarily insane and Deering is sent to the asylum, Cobleigh than forges Deering's signature and secure the invention.  Deering's daughter breaks her father out of the asylum and nurses him back to health.  The girl's sweetheart, Tom, is a lawyer who takes Cobleigh to court and reveals the forgery through a stereopticon and Cobleigh is arrested.  The film was released on September 16, 1910, and received neutral to negative reviews.  The film is presumed lost.

Foyn Coast: The Foyn Coast ( ) is that portion of the east coast of the Antarctic Peninsula between Cape Alexander and Cape Northrop.  It was discovered in 1893 by a Norwegian expedition under Captain Carl Anton Larsen, who named it for Svend Foyn, a Norwegian whaler of Tønsberg whose invention of the grenade harpoon greatly facilitated modern whaling.

Airfone: Airfone was an air-ground radiotelephone service developed by MCI founder John D. Goeken, and operated under the names "Airfone", "GTE Airfone" and Verizon.  Airfone allowed passengers to make telephone calls (later including data modem service) in-flight.  Airfone handsets were often located in the middle airliner seatbacks, with two handsets per row for 6-wide coach seating configurations, and more or less depending on the aircraft layout and fare class.  First class cabins typically had one handset per seat.  Some planes had one or more bulkhead mounted phone stations with cordless handsets that the passengers could use, instead of the multiple wired handsets.  Airfone phone calls were usually quite expensive compared to ground-based telephone calls, costing $3.99 per call and $4.99 per minute in 2006.

Alexander Graham Bell: Alexander Graham Bell (March 3, 1847 – August 2, 1922) was a Scottish-born scientist, inventor, engineer, and innovator who is credited with patenting the first practical telephone and founding the American Telephone and Telegraph Company (AT&T) in 1885.

Limited availability: When customers of a public switched telephone network make telephone calls, they utilize a telecommunications network called a switched-circuit network.  In a switched-circuit network, devices known as switches are used to connect the calling party to the called party.  Each switch has a number of inlets and outlets, and by connecting a specific inlet to the correct outlet, each switch helps to complete an end-to-end circuit between users.  This method is used in, for example graded multiple banks of selectors.
