Virtual Reality
Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings). Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR, although definitions are currently changing due to the nascence of the industry. Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vibration Reduction
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation. It is mainly used in high-end image-stabilized binoculars, still and video cameras, astronomical telescopes, and also smartphones. With still cameras, camera shake is a particular problem at slow shutter speeds or with long focal length lenses (telephoto or zoom). With video cameras, camera shake causes visible frame-to-frame jitter in the recorded video. In astronomy, the problem of lens shake is added to variation in the atmosphere, which changes the apparent positions of objects over time. Application in still photography In photography, image stabilization can facilitate shutter speeds 2 to 5.5 stops slower (exposures 4 to times lo ...

Voluntary Redundancy
Voluntary redundancy (VR) is a financial incentive offered by an organisation to encourage employees to voluntarily resign, typically in downsizing or restructuring situations. The purpose is to avoid compulsory redundancies or layoffs. Reasons A voluntary redundancy programme is not always driven by short term revenue goals. It can also be motivated by the strategic choice to change the age structure within the company. According to research, people who accept voluntary redundancy may at times return to the company after changes in the company's prospects, strategic vision, or economic climate and, in doing so, may bring new ideas. Examples LM Ericsson implemented a VR programme in the spring of 2006. It offered the programme to 17,000 employees in Sweden between the ages of 35 and 50. Those who voluntarily left were given between 12 and 16 months of severance, 50,000 kronor, and a course in entrepreneurship coupled with job placement services. The goal was to have a maximum o ...

Bristol VR
The Bristol VR was a rear-engined double-decker bus chassis which was manufactured by Bristol Commercial Vehicles as a competitor to the Leyland Atlantean and Daimler Fleetline. Development The Bristol VR was originally designed for single-deck or double-deck bodywork. The design featured a longitudinal mounted engine set behind the rear offside wheels, rather than the more typical transverse layout. A choice of Gardner 6LX or 6LW engines or the Leyland O.600 engine were to be available. The transmission was a semi-automatic unit by Self-Changing Gears. Originally intended to be designated the Bristol N-type, the chassis became known as the Bristol VR, an abbreviation for Vertical Rear, a reference to the layout of the engine. Two lengths were available, and , and these were designated VRS and VRL respectively. A drop-centre rear axle and low frame were employed to keep the height of the vehicle down. Two prototypes were built in spring 1966, and were shown at the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holden Commodore (VR)
The Holden Commodore (VR) is an executive car which was produced by Holden from 1993 to 1995. It was the third iteration of the second generation of the Holden Commodore. The VR range included the luxury variants, Holden Commodore Berlina (VR) and Holden Calais (VR) and a commercial model, the Holden Ute (VR). Overview Launched in July 1993 and sold until April 1995, the VR series came with an updated, sleeker and more modern design, as well as safety enhancements such as anti-lock brakes (ABS). It launched shortly before the Ford ED Falcon. From the side, the biggest change was the revised daylight opening around the C-pillar and the use of a round rear wheelarch, instead of a squared-off shape used on the previous VN and VP model Commodores. A Series II model launched in September 1994. The VR Acclaim and Calais included a driver's side Supplemental Restraint System (SRS) airbag as standard, which was a first for an Australian car. They also had standard ABS brakes and ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VR6 Engine
VR6 engines are V6 piston engines with a narrow angle between the cylinder banks and a single cylinder head covering both banks of cylinders. Volkswagen Group introduced the first VR6 engine in 1991 and VR6 engines currently remain in production. From 1997 to 2006, Volkswagen also produced a five-cylinder VR5 engine based on the VR6. Description The name VR6 comes from the German initials for a V engine (German: ''V-Motor'') and a straight (inline) engine (German: ''Reihenmotor''), therefore the VR engine is described as a "Vee-Inline engine" (VR-Motor). VR6 engines share a common cylinder head for the two banks of cylinders. Only two camshafts are needed for the engine, regardless of whether the engine has two or four valves per cylinder. This simplifies engine construction and reduces costs. Since the cylinders are not located on the centreline of the combined cylinder head, the lengths of the intake and exhaust ports are different for each bank. Without compensation, ...

V Speeds
In aviation, V-speeds are standard terms used to define airspeeds important or useful to the operation of all aircraft. These speeds are derived from data obtained by aircraft designers and manufacturers during flight testing for aircraft type-certification. Using them is considered a best practice to maximize aviation safety, aircraft performance, or both. The actual speeds represented by these designators are specific to a particular model of aircraft. They are expressed by the aircraft's indicated airspeed (and not by, for example, the ground speed), so that pilots may use them directly, without having to apply correction factors, as aircraft instruments also show indicated airspeed. In general aviation aircraft, the most commonly used and most safety-critical airspeeds are displayed as color-coded arcs and lines located on the face of an aircraft's airspeed indicator. The lower ends of the white arc and the green arc are the stalling speed with wing flaps in landing conf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DVD-VR
The DVD-VR standard defines a logical format for video recording on DVD-R, DVD-RW, and DVD-RAM style media, including the dual layer versions of these media. As opposed to media recorded with the DVD+VR recording standard, the resulting media are not DVD-Video compliant, and do not play back in some DVD-Video players. Most DVD video recorders in the market that support DVD-R, DVD-RW, or DVD-RAM media record to these media in DVD-VR mode, as well as in a DVD-Video compliant mode. It is possible to use the DVD-VR format with DVD+R and DVD+RW media, but no examples are known other than some PC based recording utilities. The standard was introduced in 1999 by the DVD Forum, and licensing is managed by the DVD Format/Logo Licensing Corporation. For each of the supported media, the full recording standard consists of three parts being: Physical Specifications (Part 1), File System Specifications (Part 2), and the Video Recording Specifications (Part 3).

Voltage Regulator
A voltage regulator is a system designed to automatically maintain a constant voltage. A voltage regulator may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages. Electronic voltage regulators are found in devices such as computer power supplies where they stabilize the DC voltages used by the processor and other elements. In automobile alternators and central power station generator plants, voltage regulators control the output of the plant. In an electric power distribution system, voltage regulators may be installed at a substation or along distribution lines so that all customers receive steady voltage independent of how much power is drawn from the line. Electronic voltage regulators A simple voltage/current regulator can be made from a resistor in series with a diode (or series of diodes). Due to the loga ...

Videocassette Recorder
A videocassette recorder (VCR) or video recorder is an electromechanical device that records analog audio and analog video from broadcast television or other source on a removable, magnetic tape videocassette Videotape is magnetic tape used for storing video and usually sound in addition. Information stored can be in the form of either an analog or digital signal. Videotape is used in both video tape recorders (VTRs) and, more commonly, videocasset ..., and can play back the recording. Use of a VCR to record a television program to play back at a more convenient time is commonly referred to as ''timeshifting''. VCRs can also play back prerecorded tapes. In the 1980s and 1990s, prerecorded videotapes were widely available for purchase and rental, and blank tapes were sold to make recordings. VCRs declined in popularity during the early 2000s and in July 2016, Funai Electric, the last manufacturer of them ceased production. History Early machines and formats The h ...
