Air Creation Trek. The Air Creation Trek is a French ultralight trike, designed by Air Creation of Aubenas. The aircraft is supplied as a complete ready-to-fly-aircraft.

Design and development
Developed from the earlier Air Creation GTE, the Trek was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of . The Trek features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem, open cockpit, tricycle landing gear with wheel pants and a single engine in pusher configuration.

The aircraft is made from bolted-together aluminium tubing, and is commonly fitted with the Air Creation Fun 450 wing, which has a single surface covered in Dacron sailcloth. The  span Fun wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a Japanese, twin cylinder, air-cooled, four-stroke, dual-ignition  HKS 700E engine. This engine choice provides similar reliability, smoothness and fuel economy to the Rotax 912, but at a much lower cost. With the HKS 700E engine the aircraft is designated as the Air Creation Trek 700E.

The Trek has an empty weight of  and a gross weight of , giving a useful load of . With full fuel of  the payload is .

In addition to the Fun wing, the more high performance double surface Air Creation iXess wing can alternatively be fitted.

Flakey the robot. Flakey the robot was a research robot created at SRI International's Artificial Intelligence Center and was the successor to Shakey the robot. It is featured in a Scientific American Frontiers episode (Season 5, Episode 1).

Software
Most of Flakey's routines were written in Lisp, with some lower-level code written in C. The code maintains a "Local Perceptual Space" that is updated by the sensors and acted on by planning algorithms.

Hardware
It was about 3 feet tall and 2 feet wide, and included 12 sonar sensors, optical wheel encoders, a video camera, and a depth-finding laser.

Research results
Flakey was used to demonstrate fuzzy logic and goal-oriented behavior - it would take what it knew and work towards one of several goals. At the first AAAI robotics competition in July 1992, Flakey took second place and the University of Michigan's CARMEL took first, above Georgia Tech's "Buzz" and IBM's "TJ2".

Fokker D.XII. The Fokker D.XII was a Dutch single seat, single engine fighter aircraft designed to an American specification which called for the use of a Curtiss D-12 engine, designated PW-7. Despite considerable efforts to improve the airframe, Fokker failed to win the USAAS competition.

Design and development
The D.XII owed its existence to the Fokker D.XI, even though they had no design overlap; the connection was that the earlier aircraft had some success when submitted to the USAAS's call for entrants in its PW-7 specification competition, an order for three resulting. The D.XII was intended from the start to meet this specification and was designed around the required Curtiss D-12 engine.

Initially, the D.XII was, like the D.XI, a single bay sesquiplane but its wings were different in plan and construction.  The upper wing was straight edged with some sweep on the leading edge, it had a thinner aerofoil section than that of its predecessor and was fabric rather than plywood covered.  Overhung ailerons were used, their ends projecting outboard of the squared wing tips proper, acting as aerodynamic balances. The lower wing, which lacked ailerons, was both much shorter in span and smaller in chord. The early D.XII had a V-form interplane strut on each side; another strut leant out from each wing root to the upper rear spar, assisted ahead of it on each side by a short V-form pair linking the two spars to the upper fuselage longeron, acting as N-form cabane struts.

The fuselage of the D.XII was flat sided and deep from nose to tail. Initially it had the same 300  hp (224 kW) Hispano-Suiza 8F V-eight engine as its predecessor, but this was soon replaced by the USAAS-specified 440 hp (328 kW) V-twelve water-cooled  Curtiss D-12. Both were enclosed by a metal cowlings, though of slightly different shapes, and drove a two blade propeller.  The single, open cockpit was well to the rear, about midway down the fuselage.  Its horizontal tail was braced and the fin was small, carrying a balanced rudder that extended down to the keel.  The D.XII had a fixed conventional undercarriage of the single axle type, supported by V struts.  There was a small tail skid.

The first flight under Curtiss power was made on 21 August 1924. Flight testing followed, resulting in major modifications.  The upper wing was given an unswept leading edge and hence had constant chord and the small lower wing was replaced by one with the same chord as the upper plane and a span almost its equal, mounted with marked stagger. No longer a sesquiplane, the splayed V interplane struts were replaced with more rigid N-form ones. Another bracing strut ran from the forward foot of the interplane strut to the top of the root to upper wing inner strut, to further improve torsional strength.  At the rear, the little fin was remove and the rudder, still balanced, reshaped.  Two more aircraft with these modifications were built.

Despite Fokker's efforts, the aircraft was still not to the liking of the USAAS who did not buy any of the three D.XIIs; further development was abandoned.

House raising. House raising (also called house lifting, house jacking, barn jacking, building jacking) is the process of separating a building from its foundation and temporarily raising it with hydraulic screw jacks. 

The process is the first step in structure relocation in which the building is moved to a different location. House raising may also be a part of a renovation to build a foundation under an existing house or make a house larger by adding a new floor level. Often employed in areas that are prone to flooding and storm damage, this process can be achieved through the use of either timber piles or helical piles. Once a house is raised and supported on cribbing, a new foundation can be constructed beneath it. After Hurricane Katrina and Hurricane Sandy large numbers of houses in parts of Louisiana, New York and New Jersey were raised to avoid future flooding.

Jacking and shoring, such as using jack posts, are used to hold a wooden building up during foundation and sill repairs. Little published information is available about building jacking methods. The skills are usually acquired through experience working for a building jacking or moving company.

Kersploosh!. Kersploosh!, known in Europe as Splash or Crash and in Japan as , is an action video game developed by Poisoft for the Nintendo 3DS. The game was released on the Nintendo eShop in Japan on June 7, 2011, in Europe on February 28, 2013, and in North America on March 7, 2013.

Gameplay
Kersploosh! is a game based on the premise of what an object might see when it is thrown down a well. The goal of the game is to steer the chosen object to the bottom of the well in as fast a time as possible without it breaking. Players can unlock various objects to throw down the well, including a stone, an iron ball, a jewel, a watermelon, a plate, and a matryoshka doll. Each object has unique stats for speed, boost speed, and durability. On the way down, players use the Circle Pad to steer their object in order to avoid obstacles such as wooden planks, shutters, cannons and homing cookies. Giant doughnuts can be passed through to give the object a speed boost while balloons can be popped to recover durability. There are ten wells with their own high score tables, with players able to exchange high scores via StreetPass.

Reception
Nintendo Life gave the game a score of 8/10, praising it for its addictiveness.

Sequel
A sequel, 新ひゅ～ストン (Shin Hyu~suton; New Hyu-stone), was released in Japan in 2015. It featured double the number of stones to drop and four times the amount of well to traverse.

Michael Enn Sirvet. Michael Enn Sirvet (born 1967) is an American sculptor, designer, and structural engineer. He acquired skills and exposure to traditional sculpture techniques while studying undergraduate art history as a minor at Fordham University in the Bronx, New York, and while studying for his Bachelor of Science in Civil Engineering, at the University of Maryland, College Park, by pursuing a minor in Studio Arts.

Early career
Sirvet  is largely self-taught. In his early career as an artist, while maintaining full-time employment as a structural engineer as a member of Land Sculpture Studio in Beltsville, Maryland, he worked principally at making abstract, contemporary minimalist constructions using recycled metals and wood. His first shows at Washington D.C.'s Artomatic introduced him to the larger contemporary arts community in the metropolitan area. His bowl "Millennia" was awarded Award of Distinction for Metal by the James Renwick Alliance, a program of the Renwick Gallery, Smithsonian American Art Museum.

Mid-career
Sirvet's mid-career started flourishing when he left full-time work in 2008 to concentrate on fine art sculpture and functional design.

Having experimented with new forms in the early 2000s, Sirvet still works by hand, but has also pioneered use of new industrial technology for his art, using skills learned in the engineering field to create solid forms out of structural aluminum, architectural plastics, and wood, which are sometimes combined in modular components.

Sirvet has garnered several public art installations, including two commissions for the United States' Art in Embassies Program for the United States Embassy in Valletta, Malta and the United States Consulate in Dubai, United Arab Emirates. In the United States, public art installations include Farragut Spheres for District of Columbia's Washington Metropolitan Area Transit Authority MetroArts Art in Transit program, and Red Orchard Wall for the Montgomery County Public Arts Trust.

Plexon. Plexon (from "plexus," a term describing a network of nerve cells) is an American company that "invents, develops, and manufactures hardware and software that acquires, amplifies, records, and analyzes signals from individual brain cells."  It is based in Dallas, Texas and is very close to the campus of Southern Methodist University with a satellite office in Brussels, Belgium.  It primarily services academic researchers doing work in neuroscience and electrophysiology. Plexon equipment has been used in "areas of study including autism, prosthetic limb control for paralysis patients, and the effects of drugs on brain processing and memory." In addition, it also develops equipment and software for behavioral video tracking.

History
Harvey Wiggins of Dallas, Texas founded Spectrum Scientific in 1983.  In the early days of Spectrum Scientific, design and manufacturing was conducted solely by Wiggins with backing and most funding being provided by Don Woodward at the University of Texas Southwestern Medical School and the National Institutes of Health.  In 1988, the original Multichannel Data Acquisition system (abbreviated as MAP or "Harvey box") was developed and uses hardware filtering of data signals.  The replacement for the MAP, the Omniplex system, was released in 2009 and replaces the hardware filtering components with filtering in software. Due to many contributions like these, Plexon and Harvey Wiggins have become iconic in the neuroscience community.  Dr. Regina Carelli, a professor of psychology at the University of North Carolina, describes Harvey as "wonderful--A scientist much more than a salesman."

Spectrum Scientific became known as Plexon in 1996.  Plexon celebrated its 40th anniversary in February 2023.

Since 2001, Plexon has been repeatedly recognized by the technology business community in Dallas, Texas for rapid growth.

Educational training 

Plexon sponsors an annual educational training workshop in Dallas.
