Power good signal. The Power Good signal (power-good) is a signal provided by a computer power supply to indicate to the motherboard that all of the voltages are within specification and that the system may proceed to boot and operate.

ATX Power Good
The ATX specification defines the Power-Good signal as a +5-volt (V) signal generated in the power supply when it has passed its internal self-tests and the outputs have stabilized. This normally takes between 0.1 and 0.5 seconds after the power supply is switched on. The signal is then sent to the motherboard, where it is received by the processor timer chip that controls the reset line to the processor.

The ATX specification requires that the power-good signal ("PWR_OK") go high no sooner than  after the power rails have stabilized, and remain high for  after loss of AC power, and fall (to less than ) at least  before the power rails fall out of specification (to 95% of their nominal value).

Cheaper and/or lower quality power supplies do not follow the ATX specification of a separate monitoring circuit; they instead wire the power good output to one of the  lines. This means the processor will never reset given bad power unless the  line drops low enough to turn off the trigger, which could be too low for proper operation.

Power Good values
Power good value is based on the delay in ms, that a power supply takes to become fully ready. Power good values are often considered abnormal if detected lower than 100 ms or higher than 500 ms.

Ball-Bartoe Jetwing. 

The Ball-Bartoe JW-1 Jetwing was a US research aircraft flown in the 1970s to investigate blown wing technology.

Design and development
The Jetwing was a small, mid-wing design powered by a turbofan and fitted with tail-wheel undercarriage.  The upper surface of the swept wings incorporated a slot along 70% span, through which air from the engine's fan stage could be discharged. Mounted above this slot was a small secondary airfoil called an "augmentor", intended to direct the discharged airflow over the wing. With this arrangement, it was found that the aircraft remained controllable at airspeeds as low as .

The US Navy considered developing the Jetwing for use on short aircraft carriers. A new series of test flights were then carried out. Despite its top speed of 350 mph, the Navy was able to land the Jetwing in a mere 300 feet. Ultimately, the Navy discontinued blown-wing research in favor of vectored thrust technology. Following the test program, the aircraft was donated to the University of Tennessee Space Institute in Tullahoma, which donated the Jetwing to the Wings Over the Rockies Air and Space Museum in Denver, Colorado in 2007.

Barkley-Grow T8P-1. The Barkley-Grow T8P-1 was an airliner developed in the United States shortly before the Second World War. Although it saw limited production, the type was well-received as a bush plane in Canada.

Design and development
Typical for the era, the Barkley-Grow T8P-1 was a low-wing monoplane of all-metal construction with a twin tail (an additional third tail was installed, à la Lockheed Constellation, when fitted with floats). The T8P (standing for Transport, 8 Passenger) was designed to be simple and rugged, thus the main units of the tailwheel undercarriage were not retractable, and this may have negatively impacted the type's reception in the marketplace. A novel design feature, however, was the wing structure. Barkley used what might be called a "horizontal cell" technique that has no ribs or spars.  Long tapered strips of aluminium were bent to form V shapes which were then riveted tip to tip to form an "X".  These "X"s are riveted inside the wing side by side to produce the long "cells".  This wing structure was unique to the Barkley-Grow and according to mechanics who worked on the aircraft it was very light, very stiff, very expensive to build, and difficult to repair if damaged, but it gave no problems in service.

Like its two main competitors, the Lockheed Model 12 Electra Junior and the Beech 18, the T8P-1 was originally designed to a 1935 Bureau of Air Commerce specification (eventually won by the Lockheed entry).

Operational history
Sales in the US were disappointing, only 11 being built, and most machines (seven) were sold to Canada, where the fixed undercarriage was no obstacle to the fitting of skis or pontoons.  One was selected for a record flight from Washington D.C. to Peru, and another was used in the Antarctic by the US Navy.

In 1942 A T8P-1 flown by Maritime Central Airways was used in the rescue attempt of survivors of a B-17 on the Greenland ice shelf. The aircraft was fitted with skis but force-landed on the ice on 22 December 1942 after encountering strong headwinds. The T8P-1 broke through the ice and sank leaving the pilots to be rescued by Inuit tribesmen.

The Hangar Flight Museum. The Hangar Flight Museum, formerly known as the Aero Space Museum of Calgary, is a museum located south of Calgary International Airport in Calgary, Alberta, Canada.

History
The museum was founded in 1975 as the Aero Space Museum Association of Calgary by aviation enthusiasts and former World War II pilots. It built upon the history of an earlier private collection called the Air Museum of Canada. The museum moved to its current location in a former British Commonwealth Air Training Plan hangar in 1985.

A renovation was carried out in 2016 that included replacing the roof and installing a new HVAC system. That same year, the museum changed its name to The Hangar Flight Museum.

Following a seven-year restoration, the museum's Hawker Hurricane returned in 2019. Earlier that year, it began restoring its CF-100.

The museum's annex, a building used to store aircraft from its collection, had its fabric roof badly damaged in a windstorm in March 2023. This was the second time the building had been damaged by weather. The museum is engaged in fundraising to construct a new museum building.

Exhibits
The museum has an exhibit Canadian space programs as well as an archives containing documents about aeronautics.

A central War memorial stone slab and four other memorial slabs were erected by the Aircrew Association (Southern Alberta Branch) and the Aero Space Museum Association of Calgary. The plaque  name the commonwealth air forces who trained in Calgary as part of the British Commonwealth Air Training Plan during the Second World War: Royal Canadian Air Force (RCAF); Royal Air Force (RAF); Royal Australian Air Force (RAAF); Royal New Zealand Air Force (RNZAF). In front of the slabs, a gravel mural of a Canadian roundel was painted.

The Aero Space Museum Association of Calgary erected a list of honour memorial dedicated to the Alberta Airmen who were killed in the Second World War.

The museum is affiliated with CMA,  CHIN, and Virtual Museum of Canada.

Windows accelerator. A Windows accelerator was a type of graphics processing unit for personal computers with additional acceleration features like 2D line-drawing, blitter, clipping, font caching, hardware cursor support, color expansion, linear addressing, and pattern, polygon and area fills. This functionality was marketed for accelerating the Microsoft Windows operating system. Windows accelerators have been superseded by multipurpose GPUs, which include acceleration for 3D graphics.

Most "Windows accelerator" video cards were 2D-capable fixed-function processors that received 2D drawing commands and pixel data sent from the CPU, resulting in faster window drawing. The reduced burden on the CPU, combined with the smaller data stream needed for the required instructions, resulted in improved performance compared to "dumb" frame-buffer only based video cards.

In the high-end professional market, at prices in the thousands of dollars, there were also coprocessor based video chipsets like the Texas Instrument TMS34020 available, which allowed offloading of some of the processing from the CPU to the coprocessor's videocard.

To make use of these accelerator or coprocessor based video cards, driver software for the specific video chipset was necessary.

Separation masters. Separation masters are a method of long-term preservation for most modern color motion picture film. Since monopack color film - (where materials for registering all the colors of the spectrum are contained on one film - its opposite is bipack colour film where two films face each other and the lower spectrum reds and yellows are on one film and the higher spectrum greens and blues are on another film - see Technicolor three strip) used in such processes as ECN, ECP and their successive revisions - contains photographically active color couplers which remain in the film after development, the emulsion will continue to produce chemical reactions in the image which cumulatively create a color fading, usually heavily biased towards the pink spectrum. In order to protect against this occurrence, the technique of separation masters was created.

Separation mastering is essentially an inversion of the Technicolor three-strip system, which used filtration to create three black and white masters each sensitized for one of the RGB spectrums and then printed the negatives with a CMYK colorspace. In separation mastering, the original camera negative is used to create three black and white copies, each one filtered for one of the RGB spectrums. The black and white process is considered inert after development and thus should be more stable for long-term archival, preservation, and restoration (although the film base may eventually decay regardless).

Ball-Bartoe. 
The Ball-Bartoe Aircraft Corporation was a US aerodynamics research firm and aircraft manufacturer established as a joint venture between Ball Corp and aerodynamicist Otto Bartoe in Boulder, Colorado in 1973. The firm conducted research into blown wings as a means of increasing aircraft lift at low airspeeds and constructed a research aircraft, the Ball-Bartoe Jetwing, as a testbed for these studies. The firm was dissolved in 1978.

Barkley-Grow Aircraft. The Barkley-Grow Aircraft Corporation was an American aircraft manufacturer established by Archiebald St Clair Barkley and Captain Harold Barkley Grow in Detroit in 1936 to produce a small civil transport which incorporated Barkley's patented wing design, the Barkley-Grow T8P-1.

History
Initially purchased by the General American Transportation Corporation in 1939, the company was bought by AVCO only a year later in 1940. Meanwhile, Roland A. Freeman the former chief of the experimental division, founded his own company in Santa Monica, California. The Barkley-Grow factory at the Detroit City Airport was seized by the city after a short dispute with Vultee, and turned into an aviation technical high school in 1943.

A Barkley-Grow seaplane went to Antarctica in 1939 on board the USS Bear to support the United States Antarctic Service Expedition under the supervision of Rear Admiral Richard E. Byrd.

Nicol Hugh Baird. Nicol Hugh Baird (26 August 1796 – 18 October 1849) was a Scottish surveyor who worked for his uncle Charles Baird in St Petersburg for several years, and emigrated to Canada in 1828.

Works
Baird is known in Canada for the work on various canal and road construction in Upper and Lower Canada as well as inventing equipment for making existing locks more accessible for steamships. His skills as a surveyor and engineer are reflected as an integral part of projects such as the Rideau, Trent, and Welland canals. His thorough written accounts give historians a record of early Canadian engineering.

MN-121 mine. The MN-121 is a Polish scatterable anti-tank mine, externally similar to the German AT-2 mine. The mine is cylindrical with ten wire legs which fold outward to keep the mine upright. The mine uses a magnetic influence fuze, which triggers the mine when a vehicle passes over it. The mine also has an anti-handling device which triggers the mine if it is moved. The mine's warhead is a shaped charge design containing approximately 700 grams of RDX. The manufacturer claims that it is capable of penetrating 60 millimeters of armour at an offset of half a meter.

The mine can be deployed either from aircraft, a specialised mine laying system or 122 mm artillery rockets. When required the mine is ejected from a storage canister, and shortly afterwards a small parachute is opened, which both retards the descent and keeps the mine correctly oriented as it descends. Once the mine lands on the ground the top of the mine is ejected, along with the parachute and the spring-loaded legs bring the mine upright.

The mine can be manually programmed to self-destruct after a period of 3, 6, 12, 24 or 96 hours.

 Diameter: 116 mm
 Weight: 2.8 kg

Institute for Liquid Atomization and Spray Systems. The Institute for Liquid Atomization and Spray Systems, (ILASS), is an organization of researchers, industrial practitioners and students engaged in professional activities connected with the spraying of liquids and slurries. Annual technical conferences are organized by each of the ILASS organizations ILASS-Americas, ILASS-Asia, and ILASS-Europe.  ILASS-International is board made up of representatives from the three regional ILASS Institutes.

ILASS meetings have practitioner and researchers from many areas where spray technology is utilized. This includes injectors for gas turbines, rockets, and diesels, agricultural and medical sprays, industrial sprays, fire protection, paint and coating applications, liquid combustion, and many others.  This breadth of spray applications at this conference and technical community provides cross-fertilization of research methodologies and innovative efforts.  Mechanical, agricultural and chemical engineers all participate in these meetings.

The ILASS (Institute for Liquid Atomization and Spray Systems) organization is an international organization dedicated to the advancement of knowledge and technology in the field of liquid atomization and spray systems.

The ILASS global organization has three branches: ILASS-Europe, ILASS-Americas, and ILASS Asia. ILASS-Europe was the first to be established, and was founded in 1982 as initiative of the late Prof. Paul Eisenklam. The first Annual General Meeting took place at UMIST 1983. The Institute’s objectives have remained unchanged since that time: “… to promote the science and applications of liquid atomization and spray systems by means of sponsorship of annual scientific meetings, promotion and preparation of technical papers, and promotion of membership in ILASS Europe among interested and qualified persons…”

Prof. Norman Chigier, one of the leaders of the atomization and spraying systems community and the ILASS organization founded in 1991 the Atomization and Sprays Journal that focuses publishing, peer-reviewed papers on the topics that are central to ILASS.

ILASS organizes conferences, and symposia annually in each of its branches, and every three years, three regional ILASS institutes gather in a joint conference, entitled ICLASS (International Conference of Liquid Atomization and Spray Systems).

Three awards are granted at each conference, honouring Professor Paul Eisenklam, Professor Arthur H. Lefebvre, and Professor Y. Tanasawa.
