2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98

Barnard, U.S. 20050059504, discloses a golf putt measuring device and a method for using the regulator. The golf putt measuring device has a unique configuration that allows the device to measure the speed and power rating of a golf ball that passes in front of the device. The golf putt measuring device uses infrared emitters to emit a pulse that bounces off a golf ball as it passes in front of the emitter and the pulse is received by a detector. A plurality of emitters and detectors are provided to give an accurate power, speed and/or distance reading which is displayed on a screen on the top of the device. A microprocessor controls the emitters and detectors. The microprocessor also collects the data from the detectors and converts the data to a special power rating that is then displayed on the display screen. The golf putt measuring device can be used in several different modes that may be used by an individual.

Petrov, U.S. 20050153786, discloses an object locating system that detects the presence of an object as it passes through two consecutive planar fields of view. Two pairs of optical sensor arrays with multiple, directed, pixel detectors observe the object from two angles as the object passes through each consecutive field of view. The locations of penetrations of the respective fields of view are calculated by triangulation. Using this data, the known location of the take-off point and/or the delay between penetrations, the trajectory of the object in time and space is calculated. Applications include projecting the range of a driven golf ball, measuring the respective arriving and departing velocities of a hit baseball, and determining the trajectory and origin of an arriving projectile, as in the case of the threat to a military vehicle.

Lee, U.S. Pat. No. 7,038,764, discloses an invention that is an apparatus and method for determining the velocity of a projectile. A light curtain unit creates two light curtains and two sensing planes. The projectile causes light from the light curtain to be reflected into the detectors and of the sensing planes. The time for a projectile to pass through one sensing plane to the other is measured and calculated for display by the Display Unit.

Fox, U.S. Pat. No. 5,926,780, discloses a system for measuring the initial velocity vector of a ball includes a first light sensing array, a first light source, a second light sensing array, and a second light source. The ball has an initial position. When the ball is struck, at time T1 it casts a first shadow position on first light sensing array, and at time T2 it casts a second shadow position on second light sensing array. A first plane is formed by initial position, first light source, and first shadow position. A second plane is formed by initial position, second light source, and second shadow position. The line of flight of one ball is defined by the intersection of planes. A slant distance D.sub.s is determined, whereby the speed S.sub.b of one ball is defined as S.sub.b=D.sub.s/(T2−T1). The velocity vector is then S.sub.b in the direction of line of flight.

White, U.S. Pat. No. 4,477,079, discloses a golf swing training and practice device by which a golfer may ascertain various characteristics, such as club head speed and elapsed swing time, regarding the swing of his golf club. The present training and practice device comprises a portable, battery or AC powered apparatus for accurately measuring, computing, and displaying both the elapsed time to complete the golfer's swing and the speed by which a golfer's club head is moved through a measuring zone. The measuring zone is established by the optical axes of a pair of photo detectors or the like, that are mounted within a detector head. Unlike conventional golf training or practice apparatus, the photo detectors of the present invention are responsive to ambient light. The photo detectors are disposed in parallel alignment with one another, so as to receive respective horizontal and parallel beams of light, whereby to define the measuring zone there between. The present device includes both a digital speed setting by which a golfer may set a target club head speed to achieve and a digital readout display for reporting the actual speed at which the club head is moved through the measuring zone. A pair of achievement lights provides the golfer with a momentary visual indication whether or not his actual club head speed has surpassed his desired or target club head speed. A printer may also be associated with the present device, so as to provide the golfer with a permanent indication of his club head speed and the elapsed time in which to complete his swing.

Kellogg, et al., U.S. Pat. No. 6,758,760, discloses an improved club swing training device for assisting persons, such as golfers to improve their golf swing. The training aid includes a power source, a light source such as a laser beam, a light deflector such as a mirror and a motor for rotating the light deflector. The light source, light deflector and motor are affixed to the proximal end of a club shaft. In operation, the light source strikes the light deflector which is rotated by the motor. The light deflector is angled relative to the axis of the light source's emitted beam so that upon the beam striking the light deflector, it is redirected in a second direction so as to form a fan of light as the motor rotates the light deflector. The swing training aid includes a scabbard for affixing the motor, light deflector and light source to the proximal end of a club and for positioning these components so as to position the fan of light so as to assist a person in seeing their club swing.

Lin, U.S. Pat. No. 6,923,728, discloses a golf club face impact alignment device that includes a light emitting unit and a light sensing unit. The light emitting unit includes a first light emitting device, a second light emitting device, a power source and an emitting case. The first and second light emitting devices and the power source are retained in the emitting housing. The light emitting unit is attached to the club face of a golf club. The light sensing unit includes a first sensing unit, a second sensing unit and a base. The first and second sensing units are secured to the base. Each sensing unit preferably includes at least one photocell and a sensing case. The golf club is swung between the first and second sensing units. Light emitting from each end of the light emitting unit must be detected by the first and second light sensing units to activate an indication device.

Lin, U.S. Pat. No. 6,458,038, discloses a golf putting indication device that includes a light emitting golf putter, a light sensing unit, and a display unit. The light emitting golf putter includes a light beam which projects from a strike face of the light emitting golf putter. The light sensing unit includes a plurality of photocells. Each photocell is housed in a tubular compartment. The display unit contains a plurality of light emitting devices. The number of light emitting devices corresponds to the number of photocells. Each photocell is electrically connected to a battery and to a single light emitting device. When a photocell is struck with the beam of light, the photocell's respective light emitting device emits light. In use, a golfer practices swinging the light emitting golf putter such that the light beam only enters one of the tubular compartments.

Otten, U.S. Pat. No. 6,821,211, discloses a swing analysis system that includes a housing having an upper surface and a ball support mounted to the upper surface. A first array of optical sensors is mounted in the upper surface on a first side of the ball support, and a second array of optical sensors is mounted in the upper surface on a second side of the ball support, opposite the first array of sensors. A third array of optical sensors in mounted in the upper surface, with the sensors positioned around the ball support. A controller is coupled to each sensor of the three arrays of sensors for receiving output signals therefrom. The controller monitors the output signals for change in state events and creates data files containing a sequence of events with associated timestamps. The computer is programmed to use the data files to calculate swing path angle, club head speed, club head angle, club head lateral alignment with respect to the ball support, and club head height of an implement (e.g., a golf club) swung over the housing. The system can also be provided with at least one tower attached to a side of the housing and extending above the upper surface. The tower includes additional sensors that are used by the computer to calculate club head loft angle. The computer can also calculate an effective club head speed from the measured values of club head speed, swing path angle, club head lateral alignment and club head angle.
