American Science and Engineering. American Science and Engineering Inc., (AS&E) is an American manufacturer of advanced X-ray equipment and related technologies, founded in 1958 by Martin Annis, Ph.D. Annis asked George W. Clark to join him in starting his company. Their primary work in the beginning was as a developer for NASA. Annis brought on as Chairman of the Board of Directors, Bruno Rossi, Ph.D., of MIT to help guide their efforts. Rossi had earlier confirmed the existence of cosmic rays, and postulated that black holes would emit tremendous bursts of cosmic radiation as they swallowed celestial objects. At the urging of Rossi, Annis brought on board Riccardo Giacconi, from Italy, to work on the effort to develop a detector. As a consultant to American Science and Engineering, Inc., Rossi initiated the rocket experiments that discovered the first extra-solar source of X-rays, Scorpius X-1. Despite Rossi's pivotal discoveries and work in this area, in 2002 Richardo Giacconi alone won the Nobel Prize for its discovery and invention  Nobel Prize in Physics. The AS&E team made possible the Einstein Observatory (equipped with the first full imaging X-ray telescope on board a satellite, launched in 1978). Throughout his tenure as president of AS&E (from its inception in 1958 until he left in 1993), Annis was a leading inventor/scientist for the company,  including inventing the backscatter technology, which enabled the detection of plastic explosives, he also invented the body scanner, originally developed as a machine to detect contraband in/on people for prisons, but later adopted for use in airports. Body scanners are now standard as part of pre-boarding security screenings in airports around the world. AS&E also produced the first 4th generation CT scanner for commercial use in 1976. 

The development of focusing optics for soft X-rays led also to rocket-borne solar observations, the later Skylab space station, and several successive solar observatory satellites (e.g., Yohkoh and  Hinode).
These observations enabled major steps forward in our understanding of the physics of the solar corona and of
plasma astrophysics in general.

AS&E provides both transmission X-ray and backscatter X-ray, equipment for airports, seaports, critical infrastructures, border crossings and other locations where security scanning is required. AS&E has also developed a mobile backscatter X-ray van (ZBV).

In June 2016, OSI Systems offered to purchase the company for $269 million, After approval by regulators and shareholders, the deal competed before the end of 2016.

In the 12 months ending March 31, AS&E made $64 million profit on $278 million revenue.

Wavetek. Wavetek was an electronic test equipment manufacturer that made function generators, signal generators and service monitors. Although Wavetek did not invent the function generator, it made them commercially popular. The company faced a decline starting in the late 1970s, which eventually resulted in their sale to Torrey Investments in 1991. Since then, they have continued to produce low-cost digital instrumentation.

History
Before Terrence Gooding, president and CEO of Wavetek, took Wavetek private in 1991, the company had 800 employees, 260 of whom worked in San Diego. The company had plants in the US states California, Florida, Indiana, and New York. It had overseas locations in Germany, Hong Kong and the United Kingdom.

In 1998, Wandel & Goltermann purchased Wavetek, and changed its name to Wavetek, Wandel & Goltermann (WWG).

In January 2000, test equipment manufacturer Fluke Corporation acquired Wavetek's Precision Management Division, and announced their intention to keep the Wavetek name for existing products.  WWG kept Wavetek's LAN business unit, cable networks, fiber optics and wireless test gear.

Merging
In February 2000, WWG merged with hand-held test equipment developer TTC.

In 2001, Wavetek's LAN tester division which developed the LanTEK series Ethernet test instruments was acquired by IDEAL Industries.

Acquisition
On August 3, 2005, optical communications company JDSU acquired Acterna for $760 million, which became part of JDSU's Test and Measurement Group.

Sky Soldiers. Sky Soldiers is a vertical scrolling shoot em’ up developed by Alpha Denshi and released to arcades in 1988 by Romstar in North America and SNK in the rest of the world. The game features a time travel theme as well as an organized weapon select screen at the beginning of each stage.

Story
In the year 2090, humankind invents a supercomputer called Desmoura to manage Earth's environment. Capable of replicating itself in various technological inventions, Desmoura achieves sentience as it sets itself around Earth's orbit. It becomes so powerful when it gains the capabilities to build a time machine in a matter of twenty years. Without warning or reason, Desmoura sends various war machines back in time by 100 years and starts attacking humankind's past technological feats possibly to change Earth's history. Special space fighters called STEALTHs are sent to fly against Desmoura's forces, attack the affected timelines and eventually destroy Desmoura.

Gameplay
Players travelled back in time starting in Great Britain 1945, Germany 1915, Japan 1945, Germany 1944, Vietnam 1974, France 1914, Russia 1974 and finally the space station in the present time, 2110. Each time stage has two levels, both ending in a boss battle save for the final stage, resulting in a total of 15 Areas.

The STEALTH ship weapon system is accessed in the beginning of each stage. The ship's main shot consists of a semi-automatic Wave Shot. The ship's bomb weapons include forward firing Missiles, Fire Balls, Homing missiles and the Buster bomb. The ship can be equipped with only one bomb weapon from either category at a time. The ship can only be loaded with a certain number of Bomb weapons and they can only be resupplied at the end of the level. The only pick-up item in the game is a parachuting human pilot shot down from malfunctioning fighter planes/jets; collecting these pilots results in random Bonus Points.

Reception 
In Japan, Game Machine listed Sky Soldiers on their September 1, 1988 issue as being the fourth most-successful table arcade unit of the month, outperforming titles like Ninja Spirit.

Gold(I) sulfide. Gold(I) sulfide is the inorganic compound with the formula . It is the principal sulfide of gold. It decomposes to gold metal and elemental sulfur, illustrating the "nobility" of gold.

Structure and preparation
The compound crystallizes in the motif seen for cuprous oxide: gold is 2-coordinate, sulfur 4-coordinate, and the S-Au-S linkage is linear. Linear coordination geometry is typical of gold(I) compounds, e.g. the coordination complex chloro(dimethyl sulfide)gold(I). The structure is similar to the α form of silver sulfide (argentite), which only exists at high temperatures.

It can be prepared by treating gold chloride with hydrogen sulfide It also arises by sulfiding dicyanoaurate:

This product is described as "initially dark reddish-brown" solid that turns "steel-gray".

South Australian Railways 500 class (diesel). The 500 class is a class of South Australian Railways diesel shunter locomotives built at Islington Railway Workshops between 1964 and 1969.

History
Thirty-four 500 class locomotives were built, all incorporating English Electric traction and control equipment. The first 27 were built with broad gauge bogies, the last seven with standard gauge bogies. They operated in yards at Gladstone, Murray Bridge, Naracoorte, Peterborough, Port Pirie, Tailem Bend and Wallaroo, and were deployed extensively in Adelaide.

In March 1978 all were included in the transfer of the South Australian Railways to Australian National. Some were transferred to Port Augusta. In 1986, a new computer system required the class leaders of the former South Australian Railways to be renumbered as the last member of the class, with 500 becoming 534.

Most were scrapped in the mid-1990s, and the remaining locomotives were included in the sale of Australian National's South Australian operations to Australian Southern Railroad in October 1997.

Acornsoft LISP. Acornsoft LISP (marketed simply as LISP) is a dialect and commercial implementation of the Lisp programming language, released in the early 1980s for the 8-bit Acorn Atom, BBC Micro and Acorn Electron computers.

History 

The interpreter was implemented in 6502 machine-code and was 5.5K in size. It was based on Owl LISP written by Mike Gardner of Owl Computers, which he published for the Apple II in 1979. Acornsoft licensed it from Owl Computers in 1981 and developed it for the Acorn Atom and BBC Microcomputer.

Acornsoft LISP was released on cassette, disk and ROM cartridge. The ROM cartridge version had instantaneous loading as well as a greater amount of available free RAM for user definitions.

Design 

In contrast with large-scale LISP implementations, Acornsoft's variant only had a modest number of built-in definitions as it had to fit in the limited memory space of the 8-bit Acorn computers.

The supplied LISP workspace image containing commonly used built-in functions and constants was 3K in size, although this could be deleted if not needed by the user to free up more memory.

Supported datatypes included nested lists, 16-bit signed integers and strings up to 127 characters in length. LOOP, WHILE and UNTIL keywords were available for program control.

A route-finding demo program was supplied as standard with the interpreter. The program can be loaded with the command (LOAD 'ROUTE-M) and tested by typing (ROUTE-M 'OXFORD 'CAMBRIDGE) which for example will display the output (85 CAMBRIDGE BEDFORD WATFORD OXFORD) thus showing the total mileage of the shortest possible route and listing intermediate towns visited.

Documentation 

Acornsoft also commissioned a book "LISP on the BBC Microcomputer", by Arthur Norman and Gillian Cattell, published in 1983. Arthur Norman was a lecturer in computer science at Cambridge University, and Gillian Cattell did research into LISP at Cambridge. The book was sold separately from the software and contained examples illustrating use of the Acornsoft specific features such as the VDU function allowing for machine-specific graphics capabilities. The book also contained working examples including a tree-sorting program, an arbitrary arithmetic package, an animal guessing game, a route finding program, a graphics package, a simple compiler and an adventure game. Acornsoft LISP was reportedly the basis for MetaComCo's QL Lisp product, with Arthur Norman and John Fitch being credited as authors. As a reference, the Acornsoft book by Norman and Cattell was recommended for use with the MetaComCo product.

O'PEN Skiff. The O'PEN Skiff, or O'pen Skiff, is a sailing dinghy that was designed by Vitali Design of Italy for children's sail training and as a one design racer. It was first built in 2006.

The design is a World Sailing international class.

The boat was originally marketed by the manufacturer as the O'PEN Bic, but was renamed the O'PEN Skiff in 2019.

Production
Originally produced by Bic Sport of France starting in 2006, the design is now built by Melges Performance Sailboats in the United States and remains in production. More than 8,000 boats have been delivered.

Design
The O'PEN Skiff is a single-handed training and racing sailboat. The hull is built of thermoformed, molded polyethylene, with a two-section mast and aluminum boom. It has a catboat rig, with a K.Film polyester, fully-battened  mainsail; a raked stem, an open transom; a transom-hung, composite epoxy rudder, controlled by a tiller with an extension and a retractable, composite epoxy daggerboard. The boat displaces  and may be transported on a car top or on a trailer.

Operational history

The design is widely used by hundreds of sailing clubs for training children to sail.

Russell Coutts, World Champion New Zealand sailor and America’s Cup Winner, said of the design, "the O’pen Skiff is a fantastic boat for young sailors to experience the joy of sailing. It is fast, exciting and fun to sail yet simple to rig and maintain. Many of the skills learnt in the O’pen Skiff will be easily transferred to other boats as sailors evolve and progress onto other forms of sailing."
