Golf Simulator
Indoor golf is an umbrella term for all activities in golf which can be carried out indoors. Venues include indoor driving ranges, chipping areas, putting greens, machines and home golf simulators. Many of these indoor facilities are businesses that include additional entertainment options as well as food and drink for customers. A golf simulator allows golf to be played on a graphically or photographically simulated driving range or golf course, usually in an indoor setting. In some cases, based on the location of the sensing devices, it is now possible to capture data on both ball and club for most accurate speed and directional information, and simulated ball flight behavior. The data about a golfers swing that is collected during a golf shot is extrapolated to provide ball flight trajectory and roll out according to certain calculated relationships to the ball's flight performance per the tracked motion of the ball or club, adding environmental aspects through which the ball ...

Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word ''laser'' originated as an acronym for light amplification by stimulated emission of radiation. The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow and the optical amplifier patented by Gordon Gould. A laser differs from other sources of light in that it emits light that is coherence (physics), ''coherent''. Spatial coherence allows a laser to be focused to a tight spot, enabling uses such as optical communication, laser cutting, and Photolithography#Light sources, lithography. It also allows a laser beam to stay narrow over great distances (collimated light, collimation), used in laser pointers, lidar, and free-space optical communication. Lasers can also have high temporal coherence, which permits them to emit light ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Country Club
A country club is a privately-owned Club (organization), club, often with a membership quota and admittance by invitation or sponsorship, that generally offers both a variety of recreational sports and facilities for dining and entertaining. Typical athletic offerings are golf, tennis, and swimming. Where golf is the principal or sole sporting activity, and especially outside of the United States and Canada, it is common for a country club to be referred to simply as a golf club. Many country clubs offer other new activities such as pickleball, and platform tennis. Country clubs are most commonly located in city outskirts or suburbs, because of the need for substantial grounds for outdoor activities. This factor distinguishes them from an urban Sports club, athletic club. Country clubs originated in Scotland and first appeared in the US in the early 1880s.Simon, Roger D. “Country Clubs.” In The Encyclopedia of American Urban History, edited by David R. Goldfield, 193-94. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hazard (golf)
A hazard is an area of a golf course in the sport of golf which provides a difficult obstacle, which may be of two types: (1) penalty areas such as lakes and rivers; and (2) bunkers. A penalty area was previously referred to as a water hazard. Special rules apply to play balls that fall in a hazard. For example, a player may not touch the ground with their club before playing a ball, not even for a practice swing. A ball in any hazard may be played as it lies without penalty. If it cannot be played from the hazard, the ball may be hit from another location, generally with a penalty of one stroke. The Rules of Golf govern exactly from where the ball may be played outside a hazard. Bunkers (or sand traps) are shallow pits filled with sand and generally incorporating a raised lip or barrier, from which the ball is more difficult to play than from grass. Bunker A bunker is a depression, commonly near the putting green, green or fairway (golf), fairway, that is usually filled with ...

Golf Course
A golf course is the grounds on which the sport of golf is played. It consists of a series of holes, each consisting of a teeing ground, tee box, a #Fairway and rough, fairway, the #Fairway and rough, rough and other hazard (golf), hazards, and a green with a cylindrical hole in the ground, known as a "cup". The cup holds a flagstick, known as a "pin". A standard round of golf consists of 18 holes, and as such most courses contain 18 distinct holes; however, there are many 9-hole courses and some that have holes with shared fairways or greens. There are also courses with a non-standard number of holes, such as 12 or 14. The vast majority of golf courses have holes of varying length and difficulties that are assigned a standard score, known as Par (score), par, that a proficient player should be able to achieve; this is usually three, four or five strokes. Par-3 courses consist of holes all of which have a par of three. Short courses have gained in popularity; these consist of mo ...

Air-supported Structure
An air-supported (or air-inflated) structure is any building that derives its structural integrity from the use of internal pressurized air to inflate a pliable material (i.e. structural fabric) envelope, so that air is the main support of the structure, and where access is via airlocks. The first air-supported structure built in history was the radome manufactured at the Cornell Aeronautical Laboratory in 1948 by Walter Bird. The concept was implemented on a large scale by David H. Geiger with the United States pavilion at Expo '70 in Osaka, Japan, in 1970. It is usually dome-shaped, since this shape creates the greatest volume for the least amount of material. To maintain structural integrity, the structure must be pressurized such that the internal pressure equals or exceeds any external pressure being applied to the structure (i.e. wind pressure). The structure does not have to be airtight to retain structural integrity—as long as the pressurization system that supplies ...

12 Foot Indoor Golf Green
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velocity
Velocity is a measurement of speed in a certain direction of motion. It is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of physical objects. Velocity is a vector (geometry), vector Physical quantity, quantity, meaning that both magnitude and direction are needed to define it. The Scalar (physics), scalar absolute value (Magnitude (mathematics), magnitude) of velocity is called , being a coherent derived unit whose quantity is measured in the International System of Units, SI (metric system) as metres per second (m/s or m⋅s−1). For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object is said to be undergoing an ''acceleration''. Definition Average velocity The average velocity of an object over a period of time is its Displacement (geometry), change in position, \Delta s, divided by the duration of the period, \Delt ...

Wavelength
In physics and mathematics, wavelength or spatial period of a wave or periodic function is the distance over which the wave's shape repeats. In other words, it is the distance between consecutive corresponding points of the same ''phase (waves), phase'' on the wave, such as two adjacent crests, troughs, or zero crossings. Wavelength is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. The multiplicative inverse, inverse of the wavelength is called the ''spatial frequency''. Wavelength is commonly designated by the Greek letter lambda (''λ''). For a modulated wave, ''wavelength'' may refer to the carrier wavelength of the signal. The term ''wavelength'' may also apply to the repeating envelope (mathematics), envelope of modulated waves or waves formed by Interference (wave propagation), interference of several sinusoids. Assuming a sinusoidal wave moving at a fixed phase velocity, wave speed, wavelength is inversely proportion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golf
Golf is a club-and-ball sport in which players use various Golf club, clubs to hit a Golf ball, ball into a series of holes on a golf course, course in as few strokes as possible. Golf, unlike most ball games, cannot and does not use a standardized playing area, and coping with the varied terrains encountered on different courses is a key part of the game. Courses typically have either 9 or 18 Glossary of golf#Hole, ''holes'', regions of terrain that each contain a ''cup'', the hole that receives the ball. Each hole on a course has a teeing ground for the hole's first stroke, and a putting green containing the cup. There are several standard forms of terrain between the tee and the green, such as the fairway, rough (tall grass), and various Hazard (golf), ''hazards'' that may be water, rocks, or sand-filled Glossary of golf#Bunker, ''bunkers''. Each hole on a course is unique in its specific layout. Many golf courses are designed to resemble their native landscape, such as alon ...

TrackMan
The TrackMan is a radar system that uses Doppler technology to track and record 3D characteristics of a sports ball in motion. History Trackman was created in 2003 by golfers and brothers Klaus (CEO) and Morten Eldrup-Jørgensen and radar engineer Fredrik Tuxen ( CTO). Tuxen worked with the tracking of bullets and missiles using Doppler radar. The Jorgensens contacted Tuxen to see if the technology could be used to track golf balls. The team developed the TrackMan system and demonstrated it in the United States to five golf equipment manufacturers. Mizuno, Nike, Ping, Callaway, and TaylorMade became TrackMan's first customers. TrackMan products are sold worldwide to professionals, amateurs, and businesses. The company's headquarters is in Vedbæk, Denmark. Usage Golf The TrackMan is a device that uses Doppler radar to monitor the launch of a golf ball. It is set up behind the golfer and is roughly the size of a laptop. With each swing, it measures every aspect of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
