Technology demonstration

A technology demonstration or demonstrator model, informally known as a tech demo, is a prototype, rough example or an otherwise incomplete version of a conceivable product or future system, put together as proof of concept with the primary purpose of showcasing the possible applications, feasibility, performance and method of an idea for a new technology. They can be used as demonstrations to the investors, partners, journalists or even to potential customers in order to convince them of the viability of the chosen approach, or to test them on ordinary users.

Computers and gaming

Technology demonstrations are often used in the computer industry, emerging as an important tool in response to short development cycles, in both software and hardware development.

  • Computer game developers use tech demos to rouse and maintain interest to titles still in development (because game engines are usually ready before the art is finished) and to ensure functionality by early testing. Short segments using finished game engines may be presented as game demos.
  • Graphics cards manufacturers use tech demos to showcase the performance of their cards even before there are any games that can deliver that performance or before the product is ready to be used outside of the development labs. In November 2002, Nvidia started the practice of featuring realistic female characters in graphics card technology demos, by releasing Dawn for its GeForce FX card. The demo featured a scantily-clad forest fairy with semi-realistic short hair and beautiful wings. Later Nvidia followed with similar, new demos and ATI Technologies joined the race.
  • Being by nature much less complex than complete games (that have to include dynamic physics modelling, audio engines, etc.), technology demos for graphics can deliver substantially better image quality, making the general look of games lag several years behind video card technology demos. For example, the PlayStation 2 demos Namco Girl (a lifelike female character from Ridge Racer winking flirtatiously at viewers) and old man used all the processing power to produce a high-quality single character model, in a static environment. Xbox trailers also showed Raven, a buff woman and her robot, showing off martial art moves.

Computer technology demos should not be confused with demoscene-based demos, which, although often demonstrating new software techniques, are regarded as a stand-alone form of computer art.

Google Tech Demo

Demo Slam, a website from Google Inc., as launched with the slogan "Bring your creativity. Bring your tech. Just bring it in general, fool! Demo Slam is here!", is a large collection of technology demonstrations uploaded by users, and some of the Google executives as well, which will go to the 'Contender'.

Sales engineering technology demonstration

Sales Engineering staff, often bearing the title Sales Engineer or Presales Consultant, will prepare technology demonstrations for business meetings or seminars to show capabilities of business products. This can include both software and hardware products, and can show multiple products integrating together. Usually a demonstration is less than a Proof of concept, but can come some of the way to showing how a business project may be justified. Large companies with tens or hundreds of Sales Engineers will often have a team who specialize in the production of demonstration systems and plans.

KySat-1 was an American satellite which was to have been operated by Kentucky Space. Designed to operate for eighteen to twenty four months, it was lost in a launch failure in March 2011 after the Taurus rocket carrying it failed to achieve orbit.KySat-1 was a single-unit CubeSat picosatellite which was built as part of a programme to involve and interest schoolchildren in spaceflight. Children would have been given access to the satellite; uploading and downloading data and using a camera aboard the spacecraft to produce images of the Earth. The satellite also carried a secondary technology demonstration payload; investigating the use of s band communication at high bandwidths.KySat-1 was launched by Orbital Sciences Corporation using a Taurus-XL 3110 carrier rocket flying from Launch Complex 576E at the Vandenberg Air Force Base in California. It was a secondary payload on the launch, with the primary payload being the NASA Glory spacecraft. Hermes and Explorer-1 [Prime] were launched aboard the same rocket. The launch took place at 10:09:43 UTC on 4 March 2011, and ended in failure after the payload fairing failed to separate from around the spacecraft just under three minutes after launch. With the fairing still attached the rocket had too much mass to achieve orbit, and reentered over the southern Pacific Ocean or the Antarctic. It was the second consecutive failure of a Taurus rocket, following the loss of the Orbiting Carbon Observatory in 2009.

LADEE

The Lunar Atmosphere and Dust Environment Explorer (LADEE ) was a NASA lunar exploration and technology demonstration mission. It was launched on a Minotaur V rocket from the Mid-Atlantic Regional Spaceport on September 7, 2013. During its seven-month mission, LADEE orbited around the Moon's equator, using its instruments to study the lunar exosphere and dust in the Moon's vicinity. Instruments included a dust detector, neutral mass spectrometer, and ultraviolet-visible spectrometer, as well as a technology demonstration consisting of a laser communications terminal. The mission ended on April 18, 2014, when the spacecraft's controllers intentionally crashed LADEE into the far side of the Moon, which, later, was determined to be near the eastern rim of Sundman V crater.

Lambda 4S

The Lambda 4S or L-4S was an experimental Japanese expendable carrier rocket. It was produced by Nissan and the Institute of Space and Astronautical Science and launched five times between 1966 and 1970 with Ohsumi technology demonstration satellites. The first four launches failed, however the fifth, launched on 11 February 1970, successfully placed Ohsumi-5, the first Japanese satellite, into orbit.The Lambda 4S consisted of four stages, with two booster rockets augmenting the first stage. SB-310 rockets were used as boosters, with an L735 first stage. The second stage was a reduced length derivative of the L735, whilst an L500 was used as the third stage. The fourth stage was an L480S. All of the stages burned solid fuel.The Lambda 4S could place 26 kilograms (57 lb) of payload into low Earth orbit. It was launched from the Kagoshima Space Centre. Following its retirement in 1970, a sounding rocket derived from it, the Lambda 4SC, flew three times in order to test technologies for the Mu rockets to follow. The Mu replaced Lambda for orbital launches.

OPUSAT

The Osaka Prefecture University Satellite, or OPUSAT was a technology demonstration cubesat built and operated by Japan's Osaka Prefecture University. It had a size of 100x100x100mm (without antennas and solar paddles) and build around a standard 1U cubesat bus. The primary satellite purpose is the space testing of the power system based on a Lithium-ion capacitor. The tests were largely successful, and it finished operation by reentry to Earth atmosphere on 24 July 2014. The OPUSAT is a development successor to “Maido Ichigo” satellite by East Osaka Craftmen Astro-Technology SOHLA in Osaka.

RLV Technology Demonstration Programme

Reusable Launch Vehicle—Technology Demonstration Programme is a series of technology demonstration missions that has been conceived by the Indian Space Research Organisation (ISRO) as a first step towards realising a Two Stage To Orbit (TSTO) re-usable launch vehicle.For this purpose, a winged reusable launch vehicle technology demonstrator (RLV-TD) has been configured. The RLV-TD will act as a flying test bed to evaluate various technologies like powered cruise flight, hypersonic flight, and autonomous landing using air-breathing propulsion. Application of these technologies would bring down the launch cost by a factor of 10. This project has no connection with the Avatar spaceplane concept by India's Defence Research and Development Organisation.

Reimei

Reimei ('Dawn') is the in-flight name for a small Japanese satellite known during development as INDEX (INnovative-technology Demonstration Experiment), developed in-house at JAXA both to serve as a demonstration of small-satellite technologies (particularly high-performance and high-accuracy attitude control) and to perform simultaneous optical and charged-particle observation of the aurora. A notable feature is the 25 µm-thick polyimide mirrors used for concentrating sunlight onto the solar arrays.

It is 72 cm × 62 cm × 62 cm and weighs 72 kilograms. The construction budget was $4 million. The satellite was launched into a near-sun-synchronous 630 km orbit on 24 August 2005 as a piggyback on the OICETS launch.

Trailblazer (satellite)

Trailblazer was a technology demonstration satellite, which was to have been operated by the United States Air Force and the Missile Defense Agency. It was selected for launch under a "Jumpstart" contract, to demonstrate responsiveness, with the final payload being chosen less than a month ahead of the scheduled launch date, and was launched as the primary payload of the third Falcon 1, which failed just over two minutes after launch on 3 August 2008. Two previous Falcon 1 launches also failed to reach orbit, but the fourth succeeded although it only carried a dummy payload.

It was originally built for a cancelled MDA project, and was based on a SpaceDev MMB-100 satellite bus. It was launched from Omelek Island, at 03:34 GMT. Several other payloads were to be launched aboard the same rocket, including two CubeSats for NASA, and a space burial payload for Celestis, which would have remained attached to the rocket in low Earth orbit.
