Rheinmetall RMG.50. The RMG.50 is a German heavy machine gun under development by Rheinmetall.

The RMG.50 machine gun is under development by the company under contract to the Bundeswehr as a replacement for the Browning M2HB recoil-operated heavy machine gun of the same calibre. According to a company representative, work on the RMG.50 started in 2008 and the first firings took place at the end of 2009. A second prototype was completed and started trials in August 2010. A third prototype were delivered in 2011 for internal qualification and pre-series weapons were delivered to the German Ministry of Defence test authority in 2012. The weapon entered service with the German Bundeswehr in 2014. 

Due to its weight and need for external power source it is currently only mounted on vehicles, such as the Puma .

Union Electric Telephone & Telegraph. The Union Electric Telephone & Telegraph is a historic building located in a small-scale commercial area just north of downtown Davenport, Iowa, United States.   It has been listed on the National Register of Historic Places since 1983.

History
Telephone service in the city of Davenport was initiated in 1878 when a private line was installed between the Davenport Water Company office and plant. The following year 36 subscribers in Davenport, Rock Island and Moline, Illinois were hooked up to a switchboard. That area was expanded to 41 towns along the Mississippi River by the Western Telephone Company in 1881. Iowa Telephone and Telegraph was organized the next year and started to serve Davenport residents. Union Electric Telephone and Telegraph entered the market in 1902 and they built this building in 1910. They had about 1,400 customers, but they ceased operations the following year. It was replaced by Tri-City Automatic Telephone
Company in 1912, but it lasted only a few years. Scott County had more than 50 private telephone companies in 1910. By 1916 the Iowa Telephone Company, the parent of the modern day Bell system, was the only surviving company.

Architecture
The utility company built this building for its use on the corner of Harrison and Sixth Streets. It is a brick building on a stone foundation. The two-story structure sits on a raised basement. A staircase rises to the main entrance in the center of the main level. A decorative hood crowns the entrance. Four pilasters adorn the façade on the first and second levels. They are capped by Corinthian capitals. The façade is crowned with an imposing pediment. The window openings feature roman arched windows on the second floor that are capped with a hood and a decorative keystone. The glass block and industrial-type windows are a later addition, as is the addition to the north.

Stits-Besler Executive. The Stits-Besler Executive is a three place homebuilt aircraft designed by Ray Stits, as the Stits SA-4A Executive.

Development
The project was initiated when William Besler of Besler Corp. contracted Ray Stits to design a three-place homebuilt aircraft with folding wings. Besler was an early aviation experimenter, who had mounted a steam engine of his own design on a Travel Air 2000 in 1933.

Design
The wings on the Executive fold aft and upward. Fuel tanks are embedded in the non-folding wing roots. The fuselage is welded steel tube with fabric covering. The ailerons are mounted in the center of the wing rather than the tips.

Operational history
The sole Executive, (registration no. N36K), has been used as a test bed for Besler-designed engines; a  steam engine and a two cycle, four cylinder Vee rated at .

F.J. Griffiths. Frederick J. Griffiths (December 11, 1878 - October 17, 1951) was an early, English-born engineer in the Stark County, Ohio steel industry. He is best known for working with Henry Ford to develop a vanadium alloy steel in order to produce lighter-weight, stronger automobiles. When the Massillon Rolling Mill Company merged into the Central Steel Company in June 1914, Griffiths resigned as a chemist at Canton's United Steel Company to become Central's vice president and superintendent. He then became the president of the company. His daughter, Gertrude, lit the first open hearth furnace at the new Central Steel Company in 1915. In 1917, Griffith's was named to the Massillon Steel Casting Company board of directors. The company's earliest orders came from the United States military for production of the steel-rated equipment and supplies needed for World War I. By 1919, 3 of his 5 brothers were all superintendents at Central Steel.

In 1920, Griffiths was anticipated by many in Massillon, Ohio to purchase the Massillon Tigers, of the Ohio League and take the team into the new National Football League. However he never attended a meeting regarding the league or club and the Tigers soon folded.

When Central Steel became part of Central Alloy Steel Company, Griffiths became chairman of its board of trustees. However, when that firm was absorbed by the Republic Steel Corporation, he was assigned the presidency of the Republic Research Corporation. Not wanting to conduct research, Griffth's left Republic to join the Timken Company.

Get Over It!. Get Over It! is the robotics competition event for the 2010-11 FIRST Tech Challenge. Two teams compete to score points by depositing colored batons in various types of goals. The name of the game refers to the many obstacles that traverse the middle of the field, which include a mountain, two bridges, and two ramps (which are also goals).

Rules

Alliances
The competing robots are organized into two alliances, Red and Blue. Each alliance is made up of two different teams, with one robot per team, who work together to score against the other alliance.

Field
The field is twelve feet long by twelve feet wide. Alliance stations are on opposite sides There are two zones, one for the Blue Alliance and another for the Red Alliance. The scoring objects are on the opposite side of the field relative to the alliance that will use them to score; that is, the Red Alliance's batons are in the Blue Alliance's zone and Blue Alliance's batons are in the Red Alliance's zone. Across the center of the field, there are several obstacles. At the very middle of the field is a traversable mountain, and on each side of it are balanced bridges, one red and one blue. Next to each bridge on the side opposite to the mountain is a cliff and a corrugated goal.

Scoring

The scoring object for the game is a baton. 100 batons are available for each team to use. Teams may score with either teams batons, but if they take batons from the other teams dispensers, they get penalty points. When used, doubler and magnetic batons increase the value of the points scored in a goal.

Robots primarily use batons to score points (though many robots will score only in autonomous and the endgame period). Robots may also score points by parking in specific locations during the autonomous period and the endgame period.

Autonomous Period
As with previous years' games, there is a programmed autonomous period at the beginning of each match, followed by a human controlled period. The endgame is part of the human controlled period. This year the autonomous period lasts for 40 seconds.

In addition, any batons scored (using the rules below) are counted once in the autonomous period and again in remote-controlled period, doubling the score.

Remote-control period
During the remote-control period each team has two drivers control their robot using gamepads. The remote controlled period lasts for 2 minutes.

End-game
The end game consists of the last 30 seconds of the remote-controlled period.

World Championship
This year's competition saw more robots in the FTC World Championship than any previous year. The championship was held April 27–30 in St. Louis.

Structured Financial Messaging System. Structured Financial Messaging System (SFMS) is a secure messaging standard developed to serve as a platform for intra-bank and inter-bank applications. It is an Indian standard similar to SWIFT which is the international messaging system used for financial messaging globally.

SFMS can be used for secure communication within the bank and between banks. The SFMS was launched on December 14, 2001 at IDRBT. It allows the definition of message structures, message formats, and authorization of the same for usage by the financial community. SFMS has a number of features and it is a modularised and web enabled software, with a flexible architecture facilitating centralised or distributed deployment. The access control is through Smart Card based user access and messages are secured by means of standard encryption and authentication services conforming to ISO standards.

The intra-bank part of SFMS is used by banks to take full advantage of the secure messaging facility it provides. The inter-bank messaging part is used by applications like electronic funds transfer (EFT), real time gross settlement systems (RTGS), delivery versus payments (DVP), centralised funds management systems (CFMS) and others. The SFMS provides  application program interfaces (APIs), which can be used to integrate existing and future applications with the SFMS. Several banks have integrated it with their core or centralised banking software.

The Indian Financial Technology and Allied Services (IFTAS)

With a view to provide focused attention and enable development of techno-banking in the country, the institute has promoted a new Section 8 company named The Indian Financial Technology and Allied Services (IFTAS). Headquartered in Mumbai, the mandate of the IFTAS is to provide IT-related services to the RBI, banks and other financial institutions.

Services like Indian Financial Network (INFINET), Structured Financial Messaging System (SFMS) and the Indian Banking Community Cloud (IBCC) have been handed over to IFTAS with effect from April 1, 2016.
