  • Patent number: 9233287
    Abstract: In exemplary implementations of this invention, a basketball net or flat net measures the translational kinetic energy of a ball that passes through an aperture in the net or impacts the net. The net includes one or more electrically conductive cords, which have a resistance that varies depending on the degree to which the cord is stretched. From sensor measurements, a processor determines: (a) instantaneous rate of change of resistance, and (b) duration of a time period that begins when resistance exceeds a baseline (with hysteresis). In the case of a basketball net, a processor may calculate the translational kinetic energy of the ball as equal to a sum of two terms. The first term is inversely proportional to the square of the duration; the second is proportional to the square of the integral of the instantaneous rate of change of resistance over the time period.

  • Patent number: 7993209
    Abstract: It is aimed at providing a golf address deviation detecting apparatus capable of detecting as to which of inaccuracy in loft angle, inaccuracy in lie angle, and inaccuracy in face orientation, inaccuracy, if any, occurred upon address by golf club is caused by. There is provided an apparatus comprising a light reflecting section(s) and light irradiating units, so that inaccuracies in loft angle, lie angle, and face orientation are detected and distinguished from one another, based on differences among patterns of the light-beams reflected by the light reflecting section(s).

  • Patent number: 7972221
    Abstract: A method of orienting a spherical object comprising the steps of acquiring an image of a spherical object at an imaging station; analyzing the image with a first computer to determine an analysis; transferring the object from the imaging station to orienting stations using a transfer mechanism; and orienting the object to a predetermined orientation according to the analysis; wherein the orienting stations comprise first, second, and third stations each rotating the object about a single axis; the first, second, and third stations collectively orienting the object by rotation about alternately perpendicular axes. In one embodiment, at least one of the orienting stations is at least partially mounted onto the transfer mechanism. In another embodiment, the transfer mechanism is a compliant object carrier that is movable translationally and substantially immovable rotationally. In an alternate embodiment, the ball is orientated with a gimbaled mechanism. An object orienter is also disclosed.

  • Patent number: 7959517
    Abstract: A method and apparatus for changing the temperature pattern of the surface of a golf ball or golf club is disclosed. The apparatus includes a thermal device capable of imparting a temperature pattern onto the surface of a golf ball. The thermal device preferably imparts the temperature pattern from a distance, preferably while the golf ball is positioned on a golf tee. After a predetermined amount of time, the golf ball may be stuck by a golf club. A thermal imaging device, which may detect a cooling pattern imparted to the golf ball by prongs of a cooling device, is preferably used to acquire images of the temperature pattern. The acquired images may then be analyzed by a processor to determine the kinematic characteristics of the golf ball.

  • Patent number: 7887427
    Abstract: Apparatus and a method for computing and outputting a putting backstroke instruction for a planned putt of a golf ball during recreational play. A computing means includes means for initializing or customizing according to a specific golfer putting on a specific golf green, the golfer putting at least one initializing putt a pre-selected distance on a level area of a green. During recreational play thereafter, in the preferred embodiment of the invention, the golfer, for each segment of a planned putt enters the applicable grade and length. The computing means outputs to the golfer an instruction for the length of the backstroke recommended, i.e., required for the planned putt. Another embodiment of the invention requires the inputting of the length of the planned putt but excludes the inputting of the grade of the green.

  • Patent number: 7837572
    Abstract: A launch monitor that includes substantially all of its functional components on or within a housing is disclosed. In one embodiment, the launch monitor is capable of being transported and used in any desired location. One or more camera's, flashes, and triggers may be used to acquire images of a golf club and golf ball. The launch monitor is preferably capable of receiving and transmitting data over a wireless network. Acquired images and other data may be analyzed by a processor, and then displayed using an LED, LCD or other type of display or printer. The launch monitor may “recognize” a plurality of golf clubs and golf balls based on an optical fingerprint. The optical fingerprints, which are preferably stored in a memory, allow the launch monitor to identify a golf club and/or ball substantially soon after they are placed in the field of view of the monitor Optical fingerprinting enables automatic record keeping, and storing performance data and equipment used simultaneously.
