Taslim Abstract The following document contains the final report for the Golf Ball Detector Senior Capstone Design Project. This Senior Capstone Design Group has proven the concept for a device to consistently locate golf balls. The golf ball detector is portable, easy to use, reliable, applicable in various situation and conditions, affordable to most golfers and safe for its user and the environment. The report discusses relevant background information on golf and golfers and presents the design developed by this Senior Capstone Design Group as a guide toward the solution. Preliminary researches on patent and exsisting alternatives are presented. Several preliminary design solutions that were eventually rejected are discussed in detail. After rejecting the earlier proposals, the design group decided to pursue the implantation of radio-frequency identification equipment within the ball as a solution. It has been shown that the RFID tag can still receive and transmit signals from inside a golf ball, that a passive RFID tag can survive the impact of a golf club from inside a ball, and that the addition of the tag does not significantly disrupt the physical properties of the golf ball. An RFID kit with suitable range is not currently available to the design group, but future advancements in RFID technology will complete the long- range golf ball locator. In addition to locating lost balls in play, this technology can be applied to prevent the theft of golf balls from driving ranges, saving the owners of these establishments thousands of dollars per year. 4 INTRODUCTION The importance of practice is always emphasized in golf. Professional PGA Tour player spend as much as 4 hours daily at the driving range. Not including putting, chipping, and mental preparation. In the US alone, there are over 10000 driving ranges. Most are accessible to the public. Golfers can rent golf ball in numbers

  • Odyssey Introduces Triple Track Putter Line and New Stroke Lab Black Putters
    Odyssey Introduces Triple Track Putter Line And New Stroke Lab Black Putters CARLSBAD, Calif., Jan. 16, 2020 /PRNewswire/ -- Today Odyssey Golf, the industry leader in putter innovation, made two major product announcements: 1) The launch of the new Triple Track putter line, and 2) new Stroke Lab Black putter offerings, which combine the innovative Stroke Lab shaft with a wide array of pleasing, high-performance head shapes, each with a premium black PVD finish. Triple Track Odyssey's new Triple Track putter line, consisting of five proven shapes, was developed from Callaway's Triple Track balls to help golfers aim more accurately, make consistently solid contact, and start the ball on the target-line with regularity. These three lines are prominently featured at the center of the putter head. Triple Track Technology utilizes Vernier Hyper Acuity, the same visual technology used to land planes on aircraft carriers. "We were immediately intrigued by the Triple Track golf ball," said Sean Toulon, Odyssey SVP and General Manager. "We started drawing lines on putterheads right away and sure enough, player testing showed that pairing a golf ball with a Triple Track putter promotes better accuracy." The Triple Track putter line consists of five models: TEN, Double Wide, Marxman, 2-Ball and 2-Ball blade. Each incorporates a Stroke Lab shaft and the new Microhinge Star face insert. Nationwide availability starts January 30, 2020. Stroke Lab Black The first Stroke Lab Black putters, TEN and Bird of Prey, both super-high MOI mallets, were introduced last fall. New models unveiled today include two proven blades, ONE and Double Wide; two proven mallets, SEVEN and Rossie; and a new mallet shape, the R-Line Arrow.

  • Quintic Ball Roll V2.4 the Launch Monitor for Putting
    1 Quintic Ball Roll v2.4 The Launch Monitor for Putting www.quinticballroll.com Introduction The putter… the most used club in the bag but the most overlooked part of the average golfer’s practice. Golfers around the world are using the technology available in today’s market to help analyse and improve their golf swing. Technology has transformed golf tuition and club fitting, offering golfers three dimensional frame by frame swing analysis, high-speed video and precise spin rates and launch angles that apply to the golf ball after impact. However, when it comes to putting, rather than analysing what our putting stroke and the ball are doing in detail, we simply opt to buy another putter with little more than hope as to whether it will truly improve our putting performance. Quintic Ball Roll Technology The brains behind the Quintic software is Dr Paul Hurrion - Quintic Consultancy Managing Director and international sports biomechanics adviser. Paul’s passion for golf has led him to a specialism in putting analysis and advice, assisting European Tour Professionals, holding PGA accredited Putting Clinics and being an invited Member of the Titleist Performance Institute’s Advisory Panel. He is probably best known for his work since 2002 with Padraig Harrington, Paul also works with many other top Tour Professionals including Rory McIlroy, Paul McGinley, Oliver Wilson, Robert-Jan Derksen, Lee Westwood… But what is Quintic Ball Roll Software all about… ? Quintic Ball Roll software utilises a high-speed camera (up to 260 frames per second) tracking the golf ball for the first 12 inches (30cms) of the putt.

BELOW: A But there is another way. A square-dimpled ball Bill Geisler, a past president of the Society of Hickory Golfers, sat down for a discussion about his passion for old golf clubs at Winter Park Golf Course, a short nine-holer that has drawn critical acclaim since its renovation in 2016 and proved an ideal setting for the hickory players. Geisler was there to run the Winter Park Hickory Classic, in which most of the two dozen competitors dressed in period clothes. As Geisler explains, the hickory mindset is not just about which clubs to play. It’s more of a lifestyle choice as an estimated 3,000 hickory aficionados in the U.S. embrace the gear and methodologies enjoyed by players before the introduction of steel shafts in the early 1900s. 60 GOLFWEEK ISSUE 1 . 2020 JAMES GILBERT/USA TODAY SPORTS TODAY GILBERT/USA JAMES + FOR MORE GOLF NEWS, VISIT GOLFWEEK.COM 61 LEFT: Natalie Wells of Winter Park, Florida, tees off in her hometown hickory tournament.

Old Follow this and additional works at: https://digitalshowcase.lynchburg.edu/utcp Part of the Physics Commons A Comparative Study on the Spin Rates of Golf Balls Carter Old Senior Honors Project Submitted in partial fulfillment of the graduation requirements of the Westover Honors College Westover Honors College May, 2020 __________________________ ___ Eric Goff, PHD __________________________ ___ Kevin Peterson, PHD __________________________ ___ Nancy Cowden, PHD i Abstract My research is an in-depth look at the trajectories of high-performance golf balls. These balls come from three of the top ball manufactures in the world: Titleist, Callaway and Bridgestone. We chose the low-spin ball from each company, and hit each 20-30 times using a 7- iron. We recorded the trajectory predictions using a range simulator called a FlightScope, which a ided b he U i e i f L chb g G lf g am. The purpose of this experiment was to create a computer model that compares the distance, time of flight and vertical descent of a golf ball that was predicted by the model and the simulator. 1 INTRODUCTION This study will look at the comparative trajectories between a flight simulator and a computer model of three high-performance golf balls. Information about these balls is ap- pealing because many people play golf and use these expensive golf balls, but probably have never seen any actual statistics on how different brands compare.
