A system that wirelessly integrates actual sports equipment with a computer and the internet to allow players remotely located from one another to play a competitive simulated sports game. An individual player may opt to play solo or practice to improve basic techniques. The system includes motion sensors connected to the player and a motion sensing device, all containing circuits and contact or motion sensors coupled with signal processing and radio frequency transmitter circuitry, thereby wirelessly communicate game performance information to a remote receiver-computer. The computer displays player information and visually simulates and controls a game between two players via the internet, having similar equipment and remotely located from each other. Standard sports equipment may be retrofitted with the sensors and associated circuitry to convert such equipment into “smart equipment” for use with the system. The system employs specially developed computer software to process player performance data, control game play, communicate game information between players, generate and control visual simulations and display player performance information.

A portable electronic device is disclosed. The portable electronic device comprises memory for storing instructions that are executed by a processor to perform the operations of analyzing data with the portable electronic device related to the position and motion of a putter at least one of before, during and after at least one putting stroke performed with the putter. The portable electronic device analyzes the data by utilizing a plurality of sensors within the portable electronic device including accelerometers configured to measure accelerations and gyroscopes to identify an angle of the putter during the at least one putting stroke. The portable electronic device is attached to the putter. A putting stroke characteristic can be determined based on the data generated from the sensors of the portable electronic device.

A golf training device is described, and which forms an aiming point which is directed towards a golf ball by the correct positioning of a golfer's head and body, and wherein the aiming point assists the golfer in positioning and maintaining the golfer's head and body in an appropriate orientation relative to the golf ball so that the golfer may continually view the aiming point which is directed towards the golf ball through at least a portion of the golf swing of a golfer to strike the golf ball and thereby achieve improved golfing performance.

An embodiment of an exercise monitoring apparatus is shown. Herein, the exercise monitoring apparatus comprises a casing, a fastening member, a first laser device and a second laser device. The first laser device is oriented so that, when actuated, the device outwardly projects a first light beam in a direction substantially perpendicular to a top surface of the casing. The first light beam visually produces a line of light. The second laser device is oriented so that, when actuated, the device outwardly projects a second light beam in a direction substantially perpendicular to one of the sidewalls of the casing and substantially perpendicular to the first light beam.

The present invention is directed towards a putting stroke analysis device for analyzing a putting stroke technique of a golfer. The putting stroke analysis device comprises a planar surface with a plurality of infrared emitters and co-operating infrared sensors thereon. A golfer swings their putter over the planar surface, above the plurality of infrared emitters and co-operating infrared sensors. An infrared beam, emitted by the infrared emitters, is reflected by the putter and is detected by one or more of the infrared sensors. The putting stroke analysis device has a processor which receives information from the co-operating infrared sensors and processes the information to determine putting characteristics of the putting stroke technique. The putting characteristics include, but are not limited to, speed of putter head, velocity of putter head, acceleration of putter head, speed of golf ball, velocity of golf ball, acceleration of golf ball, swing path of putter head, angle of attack of putter head, angle of putter head at impact with a golf ball, and, impact point on a putter face of the putter head at impact with a golf ball.

A golf club fitting apparatus and a method for fitting using the apparatus are provided. The golf club fitting apparatus may be attached to a golf club and provide fitting information including effective lie angle, effective loft angle, stroke plane, and aiming verification information. That golf club fitting apparatus includes a first opening for receiving a shaft, second openings for receiving a collimated light source, third openings for receiving angle indicators, and a recess for securing the collimated light source in an alternate configuration.

In a first aspect, a system for monitoring a swing is provided that includes (1) a swing measurement device adapted to couple to a swinging object and to output a signal indicative of a characteristic of the swinging object; (2) a wireless transmitter coupled to the swing measurement device and adapted to wirelessly transmit the signal output by the swing measurement device; and (3) a wireless device adapted to receive the wirelessly transmitted signal and to provide information regarding the swinging object based on the received signal. The wireless device is a cellular telephone or personal digital assistant (PDA). Numerous other aspects are provided.

An intelligent golf swing includes a swing body, a top spotlight device and a lower spotlight device. The swing body includes a middle rod and a lower rod. The lower rod is installed at the bottom end of the middle rod. The lower rod and the middle rod are arranged in a straight line. The top spotlight device is fixedly installed at the top end of the middle rod. The top spotlight device includes a spotlight and a switch. The lower spotlight device is fixedly installed on the lower rod. The lower spotlight device includes a lampwick and a button switch. A light emitted by the lampwick is allowed to be emitted from the bottom end of the lower rod, and the aforementioned light, the swing body, the lower rod and the middle rod are located on the same straight line.

A golf swing teaching device to interpret a golf swing comprising a golf club, where the golf club includes a handle, a shaft and a head; a laser attached to the golf club, where the laser directs a beam parallel to the shaft of the golf club; a reflective indicator mat, where the reflective indicator mat extends between a first end and a second end; a rest toward the first end, where the rest positions a golf ball on the reflective indicator mat; an ideal swing line along a central portion of the reflective indicator mat, where the ideal swing line extends from the first end to the second end; and a plurality of sensors along the reflective indicator mat, where the plurality of sensors detect a path of the beam over the reflective indicator mat and deviation of the beam from the ideal swing line.

A golf club fitting apparatus and a method for fitting using the apparatus are provided. The golf club fitting apparatus may be attached to a golf club and provide fitting information including effective lie angle and effective loft angle. The golf club fitting apparatus includes a lower surface that contacts a butt end of a grip, an upper surface opposite the lower surface, and a side surface connecting the upper and lower surfaces. An angle indicator is disposed at a predetermined angle relative to a shaft axis of the golf club so as to rest in a neutral position when the golf club is in a normal address position.
