Otis Hovair. Otis Hovair Transit Systems  is a type of hovertrain used in low-speed people mover applications. Traditional people mover systems used wheeled vehicles propelled by electric motors or cable traction. The Hovair replaces the wheels with a hovercraft lift pad. The aim is to reduce guideway complexity and vehicle maintenance. Another benefit is the system's ability to move in all directions, including sideways. The Hovair is the only hovertrain system to be used in commercial service.

History
Originally developed at General Motors as an automated guideway transit system, GM was forced to divest the design as part of an anti-trust ruling. The design eventually ended up at Otis Elevator who replaced its linear motor with a cable pull and sold the resulting design for people mover installations all over the world. The first installation was the Duke Hospital PRT in 1979, followed by the Harbour Island People Mover opened in 1985. Otis successfully marketed the system through the 1980s and into the 1990s, but faced increasing competition from conventional systems.

In 1996, Otis formed a joint venture called Poma-Otis Transportation Systems with the French company Poma to promote these products. The partnership has since been dissolved, and  it appears Otis is no longer involved in promoting the technology. However it is still marketed as one of the Minimetro products sold by Poma & Leitner Group. The latest installation, the Cairo Airport People Mover, opened on May 15, 2012.

Spitfire Mark II Tigershark. 

The Spitfire Mark II, later given the name Tigershark, was a utility helicopter built in the United States in the late 1970s and intended for series production. It was a further evolution of the Spitfire Mark I design, a turbine-powered conversion of the Enstrom F-28. Although airframe changes on the Mark I had been minimal, the Mark II had a substantially redesigned fuselage that rearranged the F-28's 2+2 seating to move the pilot's seat forward in the nose by itself and add a bench seat for three passengers abreast behind it. The leftmost seat on the bench could be fitted with dual controls. The fuselage was lengthened, and the powerplant installation (the same Allison 250 used on the Mark I) was mounted well to the rear. The Mark II still used the dynamic components of the F-28, plus some of its airframe.

Spitfire displayed a mockup of the Mark II at the Helicopter Association of America meeting in Anaheim, California in February 1977. The prototype first flew in February 1979 and by July that year, the company reported that it had sold 42 examples of the Mark I and Mark II and expected to build 60 aircraft during 1980.

However, Spitfire remained dependent on Enstrom to supply airframes for remanufacture, and Enstrom distanced itself from the project somewhat. Competing plans by Enstrom and Spitfire to market Polish-built Mil Mi-2 helicopters in the United States might have contributed to the friction. In Spitfire's version of the deal, Polish manufacturer PZL-Świdnik (represented by its trade bureau Pezetel) would also contribute to the Spitfire manufacturing efforts. By November 1979, Enstrom refused to supply airframes to Spitfire.

The situation improved somewhat in the 1980s, and Spitfire president Jack Fetsko reported in May 1983 that relations with Enstrom were at the point where the two companies could "talk programs". By that time, costs for the Mark II, now dubbed the Tigershark, had increased from $185,000 expected in 1979 to $305,000 but Spitfire had a firm sale for the first production aircraft. Together with companies Sodian and Soprea, Spitfire formed a new venture, Spitfire Helicopters International, to manufacture the Mark I and Mark II in Málaga, Spain.

Nothing came of the joint venture, and Spitfire's attempts to market F-28 derivatives came to an end.

Sopwith Special torpedo seaplane Type C. The  Sopwith Special torpedo seaplane Type C was the first British aircraft designed to drop torpedoes.  A single-engine biplane floatplane, it flew in July 1914 but proved unable to lift the design load and was soon abandoned.

Design and development
The Admiralty's interest in torpedo delivery by aircraft began in November 1913, expressed by an order placed with Sopwith for a "mock-up" seaplane torpedo carrier, the Sopwith Type TT. This was intended only to taxi, not fly; its trials extended over the following May and June.  In February 1914, before trials of the Type TT had begun, this contract was extended to include a second, flying, experimental torpedo carrying seaplane.  The resulting Special torpedo seaplane Type C was delivered to RNAS Calshot on 1 July 1914, carrying the RNAS serial number 170.

The Special was a four-bay biplane, with square-tipped, constant-chord, unequal-span wings connected by pairs of parallel interplane struts.  The 4 ft (1.2 m) overhangs of the upper wings were braced with an extra pair of interplane struts, leaning outwards and attached to the lower wing at the same points as the outer vertical interplane struts. There were externally interconnected ailerons on both upper and lower wings.  The lower wings were attached to the bottom fuselage and the upper ones supported well above the top of the fuselage.

The fuselage was a flat-sided girder structure; the crew occupied tandem cockpits, with the pilot at the rear.  The  Salmson 2M7 water-cooled radial engine was placed just in front of the forward cockpit, close to the wing leading edge, with tall radiators on either side of the fuselage.  It drove a two-bladed propeller via a long drive shaft within a markedly tapered nose.  The Special had a pair of strut mounted main floats, supplemented with small wingtip and tail floats.  The main floats were  long,  in the beam and  deep, spaced  apart.  Each float had two sprung connections to its struttage.

The Special's performance turned out to be very disappointing.  It was first taxi tested on 6 July 1914 at Calshot but would not take off.  It flew for the first time three days later, though with only the pilot aboard and with little fuel.  After it became clear that it could not lift its design load, it went back to Sopwith's for wing modifications.  It returned to Calshot but was found still unfit for the torpedo dropping role.  In November it was modified to carry bombs, but by January it was being broken up. In the meantime, a modified Short Admiralty Type 81 (S.84, RNAS serial 121) had become the first British aircraft to drop a torpedo, on 27 July 1914.

ITS Platform. ITS Platform is a Danish project which will develop and test the next generation of technologies in the field of ITS equipment in the years from 2010 to 2013. ITS is the abbreviation for “intelligent transport systems”, and it covers systems and services which can contribute to make the traffic of the future safer, more efficient, and more sustainable.

Concept
ITS Platform consists of a mobile unit in a car and an ITS server. The mobile unit, called the InnBox, collects information about things like the driver's position, speed, and acceleration. The collected information is sent to the server, where it will be retained and re-sent to the drivers, who thus receives targeted and individual traffic information both during and after their driving.

Applications
It is strongly emphasised that the system functions as an open platform and as the basis on which the actual ITS applications and services are built. The ITS Platform will develop four demonstration applications, which will be fully operational and may serve as inspiration for an actual product development by other interested companies. The system will contribute to relieve the traffic problems in and around the bigger cities. The four demonstration applications will consist of:
 Driving-statistics application – to collect data about driving style, and the driver is able to print a log which fulfills the demands of the Danish Tax Authority
 Personally adapted traffic information about congestion on and near the driver's route
 Parking application – automatically pays driver's parking ticket
 Cooperates with the Danish National Road Directorate on optimising the continuous traffic information for the benefit of all drivers

The participants have access to the application through a personal website, and it is possible to get information by text messages.

Industrial development
The project, which is coordinated by Aalborg University in cooperation with the companies GateHouse and Inntrasys, will be a promoter for the development of an ITS cluster anchored in North Jutland of Denmark. Here new technologies are developed and tested before they are implemented throughout the country.
The ITS Platform has a total budget of 35 million DKK (5 million €). The project is funded with DKK 17.4 million from the EU Regional Development Fund, the North Jutland Development Fund, as well as Aalborg University, GateHouse, and Inntrasys.

Cooperation
ITS Platform is based partly on thorough knowledge about mobile communication, databases and tracking by the companies Inntrasys and GateHouse and partly on a long series of results from research by Aalborg University. The InnBox is developed by Inntrasys, and GateHouse works with the ITS server. In addition to this The Municipality of Aalborg, DR (Danish Broadcasting Corporation), the Danish Road Directorate, and Nets participate in the project.

AiScaler. aiScaler Ltd. is a multinational software company founded in 2008. It develops application delivery controllers designed to allow dynamic web pages to scale content by intelligently caching frequently requested content. A number of websites in the Alexa top 1000 use aiScaler to manage their traffic.

aiScaler software can be deployed either on public cloud computing platforms such as Amazon Web Services or private virtual environments. aiScaler software is considered an edge device as it proxies traffic, augmenting or replacing content delivery networks endpoints.

History
aiScaler started as a project in 1994 by the web development company WBS. The project was called "Jxel", short for Java Accelerator. The technology was Java-based and intended to be run on a Java Virtual Machine sharing the same computer system as the HTTP server. It was re-written in 2009 using the C computer language, occupying its own dedicated server. The new software was rewritten to run on Linux only, taking advantage of changes in the input/output model based on epoll. In July 2008, aiScaler Ltd acquired all technology of WBS for $3.8 million.

Until 2013, aiScaler was known as "aiCache", producing a product called aiScaler. The company took over the name of its main product, phasing out the brand name aiCache.

Products
All aiScaler products can be categorized as Application Delivery Controllers
aiScaler is an HTTP accelerator that provides application delivery control, in addition to scaling and acceleration of content delivery 
aiProtect offers protection against DDoS attacks and SQL injections
aiMobile is a Mobile content management system 
aiCDN is a cloud-based Application Delivery Network that allows scaling of dynamic web applications.
aiScaler and Dell offer a hardware Application Delivery Controller, which fits in a standard rack unit server rack.

aiScaler is based on epoll technology allowing it to employ a right-threaded (only the specified number of workers process requests, no matter how many clients are connected), non-blocking, multiplexed IO design.

Hypergolic Maintenance and Checkout Facility. Hypergol Maintenance and Checkout Facility was a rocket fuel and engine complex located in an isolated part of the Kennedy Space Center industrial area.  It was constructed in 1964 to support the Apollo program and upgraded in 1985 to support the Space Shuttle program.  The hypergolic propellants used in the Space Shuttle's reaction control system, Orbital Maneuvering System, and the auxiliary power units provided hydraulic power to the shuttle's control surfaces, main engines and brakes were stored and processed in part of the complex.  Part of the facility was used for cryogenic testing during the Apollo program and Solid Rocket Booster aft skirt hot-testing. 

Among other structures, the facility included two hypergol storage buildings, a hazardous waste staging shelter, a liquid oxygen fuel pad, a liquid hydrogen fuel pad, leaching ponds and equipment shelters. Its Hypergol Support Building was recorded and documented by the National Park Service in 2013.

Later, part of the facility became known as the Hypergol Maintenance Facility Hazardous Waste South Staging Area.

Ross R-6. The Ross R-6 is a tandem two-seat, high-wing glider that was designed by Harland Ross and first flown in 1956.

Design and development
Ross designed the R-6 as a two-seat sailplane with the intention of setting new multi-place records with it. The aircraft was initially designed to use the same  span wing as the highly successful Ross-Johnson RJ-5, but with a gross weight of  as opposed to the RJ-5's  this gave the R-6 one of the highest wing loadings for a glider of its day.

The R-6 was constructed with a metal fuselage, which was a departure from Ross's earlier designs. The passenger seat is behind the pilot's seat, aft of the wing spar and has no windows, visibility is provided by a removable plastic overhead dome. The wing features dive brakes. The wingspan was later increased to , lowering the wing loading somewhat, but increasing the high aspect ratio to 28:1. Originally taking off from a dolly and landing on a fixed skid, the R-6 later had a retractable monowheel landing gear installed.

Operational history
In one four-day period in 1958 Ross flew the R-6 to set four records. He set new World Record marks for the multi-place glider category in ,  and  speed triangles and also set a US National Record for out-and-return distance of . Two of the three World Records exceeded the standing single-place record at the time.

In 1959, Ross flew the R-6 solo from Kent, Texas to Farley, New Mexico for his diamond distance and won the Barringer Trophy

The R-6 was later owned by Bob Storck of Waldorf, Maryland who loaned it to the National Soaring Museum, where it is currently listed as in storage.

AAON. AAON, Inc. manufactures heating, ventilation, and air conditioning equipment for commercial and industrial indoor environments. AAON is headquartered in Tulsa, Oklahoma and has manufacturing facilities in Longview, TX, Parkville, MO, and Redmond, OR. AAON employs approximately 4,000 people worldwide and has annual sales in excess of $880 million.

History 
AAON was founded in 1988 when Norman H. Asbjornson set out to create a commercial HVAC company that designed and manufactured semi-custom equipment that would excel in performance relative to the market. Asbjornson purchased the heating and air-conditioning division of John Zink and created a new company called AAON. The name ensured the company would be listed first in the phone directories.

In 1991, AAON acquired Coils Plus in Longview, TX, initially only committed to manufacturing HVAC coils. In 2000, AAON began to manufacture equipment in Longview and in 2019, broke ground on a facility expansion as part of a $28-million-dollar investment in the plant. Further expansion in Longview commenced in 2019 with the completion of a 220,000-square foot building, an additional $40 million investment. In 2023, a second $40 million expansion was approved by the Longview Economic Development Corp. and scheduled to be completed in 2024.

In 2018, AAON acquired Missouri-based WattMaster Controls (WCI) and entered a lease of the facility that was previously occupied by WCI. The WattMaster acquisition allowed AAON to begin producing their own proprietary controls systems.

In 2021, AAON acquired Oregon-based BASX Solutions (BASX). BASX designs and manufactures premium, highly customized commercial HVAC equipment for data centers, clean rooms, and other niche applications.

Edith Creek Chlorination House. The Edith Creek Chlorination House is a historic structure in Mount Rainier National Park, built by the National Park Service in 1930. The rustic structure was built as part of the water supply system to the Paradise area. The low concrete building with stone veneer cladding was built to withstand very heavy snow loads. It was fed by a small dam on Edith Creek, which was replaced in 1970. The chlorination house contained equipment to chlorinate the water from this source and to regulate the level of the reservoir.

The Edith Creek Chlorination House was placed on the National Register of Historic Places on March 13, 1991. It is part of the Mount Rainier National Historic Landmark District, which encompasses the entire park and which recognizes the park's inventory of Park Service-designed rustic architecture.
