摘要:
A portable tennis apparatus comprising a tennis bag, a tennis ball retrieving unit, a stretchable back bar and an extendable bottom stand. The ball retrieving unit retrieves balls on the ground directly to the bag; the stretchable back bar can be pulled up and pushed around with rolling means on the ground easily. The top opening of the bag made it easy to reach the balls for replay. The extendable stand can raise the tennis bag at a desirable level for dispensing balls so that the player does not have to bend down. The stretchable back bar and the stand can be put back to their original position during the transportation of the apparatus, such as between tennis court and player's home. The entire apparatus is light-weighted, easily carried and operated single-handed. This apparatus is truly an “all-in-one” tennis apparatus, and a revolution in the field of tennis equipment.

Systems, apparatuses, and methods estimate the distance between a player and a ball by transmitting a chirp (sweep signal) to a radio tag located on the ball. During the chirp, the frequency of the transmitted signal is changed in a predetermined fashion. The radio tag doubles the transmitted frequency and returns the processed signal to a transceiver typically located on the player. The currently transmitted frequency is then compared with the received frequency to obtain a difference frequency from which an apparatus may estimate the distance. The apparatus may simultaneously receive the processed signal from the radio tag while transmitting the sweep signal.

A sports apparatus for monitoring movement of a sport projectile includes a sensor and a wireless interface disposed within the sport projectile for communicating sampled data signals from the sensor, a portable communication device in wireless communication with the wireless sensor for receiving sampled data signals from the wireless sensor, the sampled data signals indicative of a motion of the sport projectile. The portable communication device includes a controller having a memory including programming instructions that when executed by the processor cause the controller to detect a sensor signal from the wireless interface, determine a motion characteristic of the sport projectile from the motion characteristic from the sensor signal, and determine if the motion characteristic is passage of the sports projectile through a goal structure, motion of the sports projectile after a shot or an impact of the sport projectile with an object.

The present invention relates to a portable strength training device which can be adapted to various sports and can be utilized in almost any location. More, specifically present invention is a weighted elongated tubular member which includes connectors for attachment of various balls and/or sporting equipment. The training device is adjustable through the use of various sized hollow tubes of different lengths and/or diameters which allow for the addition of one or more types of weight material within the hollow lumen. Various different sports objects, such as balls, golf club handles, tennis racket handles, baseball bats and the like can be secured to one of the distal ends of the hollow tubes. Clips hooks or the like may be secured to the opposite distal end of the tube for anchoring the device.

An athletic training device trains athletes to observe the collision between a ball and bat, club, racquet, or the like. The training device may provide a unique event, such as a flashing light, at the moment of the collision. Athletes can be trained to watch the ball, bat, club, racquet or the like, to note the flash of light, thereby focusing the attention of the athlete to “keep their eye on the ball”. The training device of the present invention can provide a unique event that attracts and induces anticipation from the collision point itself. The unique event can be a light flash, multiple light flashes, colored light flashes, or the like.

A device, system and method for managing swinging effectiveness of a sports related striking object configured to strike a struck object, is disclosed. The struck object may have a struck object diameter. The device may include a chalklike material, a substantially spherical shape, and a diameter of between approximately ⅕ to ⅓ the struck object diameter. The method may include: placing a first substantially spherical chalklike object on a golf tee; taking a first swing with a golf club and striking the substantially spherical chalklike object with a golf club thereby leaving a chalklike mark on a striking surface of the golf club; viewing the chalklike mark on the striking surface, and noting a first difference between a location of the chalklike mark and a sweet spot on the striking surface; placing a second substantially spherical chalklike object on the golf tee; taking a second swing with the golf club and striking the second spherical chalklike object with the golf club and adjusting the second swing in order to minimize a second difference between a second chalklike mark made from striking the second spherical chalklike object and the sweet spot on the striking surface based on the first distance noted in the noting.

An exercise training system is provided having a system controller and a plurality of stimulant target units connected via a wireless network to the system controller. Each stimulant target unit has a light source providing light to stimulate a user, a proximity sensor providing an output of a distance between the proximity sensor and an object external to the unit, and means for providing feedback to the user to signal that the unit has been actuated by the user. The system controller includes a program for activating the stimulant target units in a sequence. The reaction by the user to the illumination is registered when the user brings a body part or other object to within a selected distance of the proximity sensor, this distance being programmable by the user.

A tennis ball pick-up cart comprises a chassis including a pair of driven wheels and a pair of steering wheels. A ball collection case is coupled to the chassis. A ball pick-up mechanism includes a concave ball guiding plate laterally placed under two vertical side plates. The ball pick-up mechanism also includes a fixing shaft and a rotating shaft each laterally extending between the vertical side plates. Synchronous belt pulleys are provided on the fixing shaft and the rotating shaft. Two synchronous belts are assembled with two of the synchronous belt pulleys. Laterally placed ball-moving plates are evenly distributed on an outer surface of each of the synchronous belts. Each of the ball moving plates includes a ball moving surface perpendicularly connected to the outer surface of each of the belts. An electric motor drives the driven wheels and the rotating shaft.

In one aspect, an apparatus for measuring a tension force on a net cord of a sports net is disclosed. The apparatus may include a housing configured to connect to a static post. The apparatus may also include a slidable member and attachment members. The attachment members may be configured to engage a portion of the net cord. A resilient member inside the housing may be connected to the slidable member, and an indicator member may be connected to the slidable member within the housing. The slidable member may be configured to move within the housing in response to and by a distance proportional to an amount of tension force on the net cord. The indicator member may be connected to the slidable member such that a portion of the indicator member may be exposed through a slotted opening defined in the housing.
摘要:
A sports apparatus is provided for monitoring movement of one or more projectiles associated with a sporting event. The apparatus includes a data processing system for processing sampled data signals generated in operation by one or more sensors (202, 204) included in the one or more projectiles. Moreover, the apparatus includes a mobile telephone coupled in wireless communication with the one or more projectiles for receiving the sampled data signals indicative of motion of the one or more projectiles. Furthermore, the mobile telephone is operable to execute one or more software products therein for analyzing the sampled data signals received at the mobile telephone for providing analysis results indicative of a nature of trajectory of the one or more projectiles.
