Oracle (rocket). Oracle is the name of a model rocket with built-in digital camera, manufactured by Estes Industries, for aerial photography. In contrast to the camera rocket Astrocam, the Oracle allows the making of a complete film of a rocket flight. The Oracle is best flown with a D12 engine (see Estes number coding), but can be flown with C11 engines.

During launch, the camera films downward; showing the launch pad and engine exhaust during ascent.  The rocket's nose cone may be attached to the parachute in two ways; there are attachments on both ends of the nose cone. Attaching the parachute to the bottom films the parachute during descent. Attaching the parachute to the top films the approach of the ground during descent.

The nose-cone attaches to a PC via USB. The resulting AVI file contains approximately 30 (between 30 and 35) seconds of uncompressed video at 9 frame/s at a resolution of 320 pixels wide by 240 pixels high (320x240). The data rate is 2047 kbit/s. The camera holds only one video at a time.

INAP. INAP stands for Intelligent Network Application Protocol or Intelligent Network Application Part. It  is the signalling protocol used in Intelligent Networking (IN). It is part of the Signalling System No. 7 (SS7) protocol suite, typically layered on top of the Transaction Capabilities Application Part (TCAP). It can also be termed as logic for controlling telecommunication services migrated from traditional switching points to computer based service independent platform.

Applications
The International Telecommunication Union (ITU) defines several "capability levels" for this protocol, starting with Capability Set 1 (CS-1). A typical application for the IN is a Number Translation service. For example, in the United Kingdom, 0800 numbers are freephone numbers and are translated to a geographic number using an IN platform. The Telephone exchanges decode the 0800 numbers to an IN trigger and the exchange connects to the IN.

The telephone exchange uses Transaction Capabilities Application Part (TCAP), Signaling Connection and Control Part (SCCP) and INAP and in IN terms is a service switching point (SSP). It sends an INAP Initial Detection Point (IDP) message to the service control point (SCP). The SCP returns an INAP Connect message, which contains a geographic number to forward the call to.

INAP messages are defined using ASN.1 encoding. SCCP is used for the routing. Extended form of INAP is Customised Applications for Mobile networks Enhanced Logic (CAMEL). TCAP is used to separate the transactions into discrete units.

Flavors (programming language). Flavors, an early object-oriented extension to Lisp developed by Howard Cannon at the MIT Artificial Intelligence Laboratory for the Lisp machine and its programming language Lisp Machine Lisp, was the first programming language to include mixins. Symbolics used it for its Lisp machines, and eventually developed it into New Flavors; both the original and new Flavors were message passing OO models. It was hugely influential in the development of the Common Lisp Object System (CLOS).

Implementations of Flavors are also available for Common Lisp.

New Flavors replaced message sending with calling generic functions.

Flavors offers  and  daemons with the default method combination (called ).

Laser level. In surveying and construction, the laser level is a control tool consisting of a rotating laser beam projector that can be affixed to a tripod. The tool is leveled according to the accuracy of the device and projects a fixed red or green beam in a plane about the horizontal and/or vertical axis.

Development
The concept of a laser level has been around since at least the early 1970s, the original spinning-mirror design laser plane and line level was patented by the late 1980s, and the compact lens-based laser line level (as produced by many tool manufacturers today) was patented in the late 1990s. It was invented by Oscar Soliz in the late 1960s, who later sold the rights to it.

Rotary laser level
A rotary laser level is a more advanced laser level in that it spins the beam of light fast enough to give the effect of a complete 360 degree horizontal or vertical plane, thus illuminating not just a fixed line, but a horizontal plane. The laser beam projector employs a rotating head with a mirror for sweeping the laser beam about a vertical axis.  If the mirror is not self-leveling, it is provided with visually readable level vials and manually adjustable screws for orienting the projector. A staff carried by the operator is equipped with a movable sensor, which can detect the laser beam and gives a signal when the sensor is in line with the beam (usually an audible beep). The position of the sensor on the graduated staff, also known as a grade rod, or story pole, allows comparison of elevations between different points on the terrain. Most laser levels are used in the construction industry.

Tower-mounted laser level 
A tower-mounted laser level is used in combination with a sensor on a wheel tractor-scraper in the process of land laser leveling to bring land (for example, an agricultural field) to near-flatness with a slight grade for drainage.

USS Ammen (DD-35). The first USS Ammen (DD-35) was a  in the United States Navy during World War I and later in the United States Coast Guard, designated as CG-8. She was named for Rear Admiral Daniel Ammen.

Construction
Ammen was laid down on 29 March 1910 by the New York Shipbuilding Company, Camden, New Jersey; launched on 20 September 1910; sponsored by Miss Ethel C. Andrews; and commissioned at Philadelphia, Pennsylvania on 23 May 1911. Construction cost $655,075.13 (hull and machinery).

World War I
Following commissioning, Ammen was assigned to the Atlantic Fleet. She operated with the Torpedo Flotilla along the east coast. Upon the outbreak of World War I in Europe in 1914, Ammen began neutrality patrols and escort duty along the east coast. After the United States entered the conflict in April 1917, Ammen sailed for the Bahamas on a reconnaissance mission. When she returned to the United States, the destroyer entered the Philadelphia Navy Yard on 6 May to be fitted out for overseas service. Ammen was assigned to Division 9, Destroyer Force, and sailed on 18 June for St. Nazaire, France.

After the arrival of the convoy at St. Nazaire on 2 July, Ammen proceeded to Queenstown, Ireland, and was attached to American naval forces based there. The ship carried out convoy escort duty between Ireland and France, patrolled off the Irish coast for enemy submarines, and went to the aid of vessels in distress. Ammen returned to the United States in January 1919. She made a cruise to the Gulf of Mexico before going out of commission at Philadelphia on 11 December 1919. The vessel was designated DD-35 on 17 July 1920.

Inter-war period
Ammen remained at Philadelphia, Pennsylvania until 28 April 1924, when she was transferred to the Coast Guard, in whose hands she was redesignated CG-8. Ammen was one of 20 destroyers that formed the Coast Guard Offshore Patrol Force, established to help suppress bootlegging.

On 22 May 1931, Ammen was returned to the Navy, but she performed no further active service. Her name was dropped on 1 July 1933, and thereafter she was referred to as DD-35. She was struck from the Naval Vessel Register on 5 July 1934 and sold to Michael Flynn, Inc, Brooklyn, New York.

SIMON breach grenade. The SIMON is an Israeli bullet-trap rifle grenade designed to breach through doors, developed by Rafael Advanced Defense Systems. It is intended for use with 5.56 mm rifles such as the M4 carbine.

Overview
The system consists of a bullet-trap tail section which slides over the muzzle of the rifle, an explosive midsection and a front standoff rod.  The grenade is propelled by a normal ball or tracer round to a maximum range of  and is detonated by the impact of the standoff rod against the door to be breached, the standoff distance allowing the blast wave to affect as much of the door surface as possible, negating any need to aim for hinges or locks.

A version which is manually attached to the door is also available, known as "static SIMON".

  - A variant of the SIMON 120 is in service with the U.S. Army as the M100 Grenade Rifle Entry Munition (GREM). Changes from the original specification involved fuzing and reliability issues. An inert round, the M101 GREM-Target Practice (GREM-TP) allows training for accuracy without the explosive hazard. The system was given a U.S. Army award as one of the top ten best inventions of 2005.
  - Used by the Belgian Federal Police Special Units supported by the French GIGN during an anti-terrorism raid in Verviers (Belgium) in 2015.

Defex. Defex is a comic book series printed by Aftermath (itself an imprint of Devil's Due Productions). It was first published in October 2004. Its creators are Marv Wolfman (writer), Stefano Caselli (pencils), and Sunder Raj (colors). Six issues of Defex have been printed.

Plot
The story is set around a group of students taking a college course in which they are asked to list ways in which society could benefit from the application of nanotubes. They are assigned together apparently at random, and they decide their topic: using nanotubes to alter human DNA, giving them access to abilities which are latent in the human genome. When they present their thesis, the university refuses to let them test it. During the night they test the nanotubes upon themselves and awake with superhuman abilities.

It has been implied that the experiment that gave them their powers has some connection to Jeff Carey, aka Breakdown, who stars in another of Aftermath's titles.

Characters
Ariel Davis (alias Six) - A young woman who has all of her senses heightened to a super human level, with an extra sixth sense
Jack Morgan (alias Idol) - A young man with the ability to control pheromones and hormones at will
Mia Sanchez (alias Rush) - Young woman who is able to control her adrenaline
Haley Rin (alias Chimera) - Young man who has animal-like transformations, limited to vertebrates

Wei Yen. Wei Yen () is a Taiwanese-American technologist and serial entrepreneur. He has been involved with several companies, including most recently as Chairman and Founder of AiLive.

Yen received his Ph.D. in Electrical Engineering in Operating Systems and Artificial Intelligence from Purdue University. Yen and his brother David Yen along with King-sun Fu published the paper "Data Coherence Problem in a Multicache System" that describes a practical cache coherence protocol.

Career
Yen served as the Director of Software Engineering for Cydrome, where he worked with his brother David, who served as the Director of Hardware Engineering. They were the major contributors to the Cydra-5 mini-supercomputer. The system was a combination of a VLIW ECL-based processor used for scientific applications and a multi-processor system designed for a bus architecture based on their Cache Coherence protocol.

Yen served as Senior Vice President of Silicon Graphics from 1988 to 1996, where he led development on OpenGL and also served as President of subsidiary MIPS Technologies. In 1996, he left SGI and founded TVsoft, a maker of interactive software for television setup devices. The company was renamed Navio and later merged with Oracle's Network Computer. Subsequently, the company went public as Liberate Technologies in July 1999. Its public offering reached a $12 billion valuation in early 2000 with a revenue run rate of $25 million.

In parallel, Yen founded a company called ArtX, employed with former SGI graphics engineers. ArtX received the contract to deliver the GameCube's Flipper graphics chip. The company was acquired by ATI in February 2000 for $400 million. This led to ATI's greatly improved R300 graphics chip family. Yen later joined ATI's board of directors.

With Nintendo, Yen cofounded another company iQue, the manufacturing and distributing arm of Nintendo for mainland China.

Yen founded iGware, a company that offers cloud computing services to its customers, including Nintendo. iGware's cloud services power the online services of the Nintendo DS, Wii, Nintendo 3DS, and Wii U. In July 2011, Acer, of which Yen is a former board member, acquired the US-based iGware for $320 million, and thus iGware becomes a part of Acer's company structure in providing cloud services. iGware changed its name to Acer Cloud Technology Co. and continued to be headed by Yen. As a result of the acquisition, Yen is the second largest shareholder of Acer after founder Stan Shih.

Yen is currently the chairman and founder of AiLive, the company that partnered with Nintendo in developing software tools for programmers working with the Wii Remote controller and Wii MotionPlus attachment.

Yen has been on the board of several prominent companies including Acer, ATI, MoSys, and others.

NexTView. NexTView was an electronic program guide for the analog domain, introduced in 1995 and based on Teletext Level 2.5 / Hi-Text.

It was used by TV programme listings for all of the major networks in Germany, Austria, France and Switzerland. The transmission protocol was based on teletext, however, using a compact binary format instead of preformatted text pages. The advantage compared to paper-based TV magazines was that the user had an immediate overview of the current and next programmes, and was able to search through the programme database, filtering results by categories.

The nxtvepg software enabled nexTView to be viewed using a personal computer.

Some TV manufacturers that implemented this solution were: Grundig, Loewe, Metz, Philips, Sony, Thomson, and Quelle Universum.

From 1997 to October 2013, NexTView was broadcast on Swiss Television channels and on French-language channels whose teletext services were managed from Swiss Television (SwissText) (TV5, M6, Canal+).

Vacuum arc. A vacuum arc can arise when the surfaces of metal electrodes in contact with a good vacuum begin to emit electrons either through heating (thermionic emission) or in an electric field that is sufficient to cause field electron emission.  Once initiated, a vacuum arc can persist, since the freed particles gain kinetic energy from the electric field, heating the metal surfaces through high-speed particle collisions. This process can create an incandescent cathode spot, which frees more particles, thereby sustaining the arc. At sufficiently high currents an incandescent anode spot may also be formed.

Electric discharge in vacuum is important for certain types of vacuum tubes and for high-voltage vacuum switches.

The thermionic vacuum arc (TVA) is a new type of plasma source, which generates a plasma containing ions with a directed energy. TVA discharges can be ignited in high-vacuum conditions between a heated cathode (electron gun) and an anode (tungsten crucible) containing the material. The accelerated electron beam, incident on the anode, heats the crucible, together with its contents, to a high temperature. After establishing a steady-state density of the evaporating anode material atoms, and when the voltage applied is high enough, a bright discharge is ignited between the electrodes.

IAI Harpy. The IAI Harpy is a loitering munition missile produced by Israel Aerospace Industries. The Harpy is designed to attack radar systems and is optimised for the suppression of enemy air defences (SEAD) role. It carries a high explosive warhead. The Harpy has been sold to several foreign nations, including South Korea, India and China.

Design and development
In the late 1980s, Kentron sold the designs for its ARD-10 loitering drone to IAI. IAI then used those designs to develop the Harpy which was first tested in 1989.

In 2004, the Harpy became the focus of the effort by the United States to restrict arms transfers and the sales of advanced military technology to China. Sold to China in 1994 for around US$55 million, the loitering munitions were returned to Israel in 2004 under contract to be upgraded. The United States, fearing that the Harpy would pose a threat to Taiwanese and American forces in the case of a war with China, demanded that Israel seize the loitering munitions and nullify the contract. According to Israel, the Harpy is an indigenously designed loitering munition, and does not contain any US-produced sub-systems. In 2005, the loitering munitions were returned to China without being upgraded. This incident chilled relations between the United States and Israel, with Israel being suspended from its status as Security Cooperative Participant in the Joint Strike Fighter program. However, on 6 November 2005, Israel stated that it has been re-admitted into the program.
