Hybrid vehicle

• DEFINITION

A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine to drive an electric generator that powers an electric motor,^[1] e.g. in diesel-electric trains using diesel engines to drive an electric generator that powers an electric motor, and submarines that use diesels when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids.

•  INVENTION    

   The first hybrid car was in part the brainchild of a Viennese coach builder named Jacob Lohner, who felt that gas-driven cars were too noisy and smelly. To find a solution to this problem, Lohner turned to a young Austrian engineer named Ferdinand Porsche. In 1896, when he was just 21 years old, Porsche had invented the electric wheel-hub motor, a battery-operated motor that actually fit inside the hub of a wheel. Lohner asked Porsche to combine his in-wheel motors with one of Lohner's coaches. The result was the Lohner-Porsche Electrolcar. This vehicle was first shown to the general public at the Paris Exposition of 1900.

unmanned aerial vehicle (UAV) or drone

• DEFINITION

An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot aboard. UAVs are a component of an unmanned aircraft system (UAV); which include a UAV, a ground-based controller, and a system of communications between the two. The flight of UAVs may operate with various degrees of autonomy: either under remote control by a human operator or autonomously by on board computers.^[1]

• USES

Compared to manned aircraft, UAVs were originally used for missions too "dull, dirty or dangerous"^[2] for humans. While they originated mostly in military applications, their use is rapidly expanding to commercial, scientific, recreational, agricultural, and other applications,^[3] such as policing, peacekeeping,^[4] and surveillance, product deliveries, aerial photography, agriculture, smuggling,^[5] and drone racing. Civilian UAVs now vastly outnumber military UAVs, with estimates of over a million sold by 2015, so they can be seen as an early commercial application of autonomous things, to be followed by the autonomous car and home robots.

virtual reality (VR)

• DEFINITION

Virtual reality (VR) is a computer technology that uses virtual reality headsets or multi-projected environments, sometimes in combination with physical environments or props, to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual or imaginary environment. A person using virtual reality equipment is able to "look around" the artificial world, and with high quality VR move around in it and interact with virtual features or items. The effect is commonly created by VR headsets consisting of a head-mounted display with a small screen in front of the eyes, but can also be created through specially designed rooms with multiple large screens.
     

• FUNCTIONING

VR systems that include transmission of vibrations and other sensations to the user through a game controller or other devices are known as haptic systems. This tactile information is generally known as force feedback in medical, video gaming and military training applications. Virtual reality also refers to remote communication environments which provide a virtual presence of users with through telepresence and telexistence or the use of a virtual artifact (VA). The immersive environment can be similar to the real world in order to create a lifelike experience grounded in reality or sci-fi. Augmented reality systems may also be considered a form of VR that layers virtual information over a live camera feed into a headset, or through a smartphone or tablet device.
