Space Activity Suit
A space activity suit (SAS) or mechanical counterpressure suit is an experimental spacesuit which applies stable pressure against the skin by means of skintight elastic garments. The SAS is not inflated like a conventional spacesuit: it uses mechanical pressure, rather than air pressure, to compress the human body in low-pressure environments. Development was begun by NASA and the Air Force in the late 1950s and then again in the late 1960s, but neither design was used. Research is under way at the Massachusetts Institute of Technology (MIT) on a "Bio-Suit" System which is based on the original SAS concept.

Army Ground Mobility Vehicle
The M1297 Army Ground Mobility Vehicle (A-GMV or AGMV), previously just GMV, and formerly called the Ultra Light Combat Vehicle (ULCV), is a U.S. Army airdroppable light off-road vehicle for light infantry brigades. The A-GMV is produced by General Dynamics. The design is closely based on the M1288 GMV 1.1, which is itself based on the Flyer 72. In March 2015, the Army changed the name of the Ultra Light Combat Vehicle to the Ground Mobility Vehicle. A-GMV is intended to be carried internally in a CH-47 Chinook or externally by a UH-60 Black Hawk. In order to be survivable but transportable, the GMV would be lightly armored and use speed, maneuverability, and off-road mobility to avoid major threats. The A-GMV is configured to carry an airborne infantry combat squad of nine paratroopers, and their gear – a payload capacity of over 5,000 pounds (2,300 kg). The vehicle has an open design, modifiable into flexible configurations, by remote and manned turrets, armor, or arctic kits. The AGMV was a limited purchase through USSOCOM's GMV 1.1 program. The Infantry Squad Vehicle will be purchased in greater numbers.

Working Bikes
Working Bikes is a not-for-profit tax-exempt 501(c)3 volunteer-driven organization based in Chicago, IL that aims to divert bicycles from the waste stream and put them to use in Chicago and abroad. It operates a warehouse, shipping center, repair shop and retail outlet from its location in the Pilsen neighborhood. Working Bikes mission is to provide bicycles to charity organizations in the Chicago area to benefit youth, transitioning homeless and refugees as well as to ship bicycles to the Gulf Coast and around the world. Each year Working Bikes aims to sell 2,000 refurbished bikes through its storefront and runs a repair shop to keep bikes in operation. It uses the proceeds from these activities to give away approximately 6,000 bikes per year. Since its inception, as cited within the Working Bikes 2018 Annual Report, "More than 70,000 bikes have been given new life across our region and the world".

105×617mm
The 105×617mm (4.1 inch) also known as 105 × 617 R is a common, NATO-standard, tank gun cartridge used in 105mm guns such as those derived from the Royal Ordnance L7. The 105 × 617 R cartridge was originally developed from the 84 mm (3.3 in) calibre Ordnance QF 20-pounder 84 × 618R cartridge as part of the development of the L7 105 mm rifled gun.

Thyristor Switched Capacitor
A thyristor switched capacitor (TSC) is a type of equipment used for compensating reactive power in electrical power systems. It consists of a power capacitor connected in series with a bidirectional thyristor valve and, usually, a current limiting reactor (inductor). The thyristor switched capacitor is an important component of a Static VAR Compensator (SVC), where it is often used in conjunction with a thyristor controlled reactor (TCR). Static VAR compensators are a member of the Flexible AC transmission system (FACTS) family.

Soling
The Soling is an International open keelboat class designed by Jan Linge from Norway in 1965. In 1968, it was selected to be an Olympic class for the Games of the XX Olympiad in Kiel 1972 (GER). The Soling maintained this status until her final appearance at the 2000 Olympics. The Soling is a strong boat designed for any wind and sea condition. The boats are one-design originating from an authorized single plug and mould and made of glass reinforced polyester, making competition as equal as possible. The lifetime of a Soling is long. Those produced in the early days are still in competition (more than 50 years after being built). At the 2019 North American Championship the 5th place was taken by a German team (GER 1) sailing a refurbished Soling build in 1968. Characteristic for the Soling is the droop-hiking technique. Since 2008, the Soling is one of the Vintage Yachting Classes at the Vintage Yachting Games.

List of AEW&C Aircraft Operators
Airborne early warning and control (AEW&C) aircraft are airborne radar systems designed to detect and track aircraft, missiles, ships and vehicles and provide command and control to direct friendly forces. Some operators, such as the Royal Air Force refer to such aircraft as Airborne early warning (AEW), while others reserve the shorter name for AEW aircraft lacking command and control facilities.

Intel 80486
The Intel 80486, also known as the i486 or 486, is a higher performance follow-up to the Intel 80386 microprocessor. The 80486 was introduced in 1989 and was the first tightly pipelined x86 design as well as the first x86 chip to use more than a million transistors, due to a large on-chip cache and an integrated floating-point unit. It represents a fourth generation of binary compatible CPUs since the original 8086 of 1978. A 50 MHz 80486 executes around 40 million instructions per second on average and is able to reach 50 MIPS peak performance. Approximately twice as fast as the 80386 or 80286 per clock cycle, thanks to its five stage pipeline with all stages bound to a single cycle. The on chip enhanced FPU unit was also significantly faster than the 80387 per cycle.
