摘要:
A vibration dampening device for use with a racket having a plurality of strings may have a fastener element which may include a male fastener and a female fastener which are configured to be coupled to each other. A hinge may pivotally couple a first arm to a second arm. The first arm may comprise a first arm interior surface and the female fastener. The second arm may comprise a second arm interior surface and the male fastener. The device may be secured to the strings of a racket by positioning the second arm interior surface and first arm interior surface to embrace two strings of the racket when the male fastener is coupled to the female fastener.

A solution is provided to enhance motion detection and recognition of moving objects associated with various sports by intelligently embedding motion sensors into sport instruments such as tennis rackets, badminton rackets, baseball bats and golf clubs, that are swung in a three-dimensional (3D) space. The motion sensors embedded inside the sport instruments are securely locked and are detachable for replacement. A motion sensor inserted and locked inside a sport instrument is configured to detect motions associated with movements associated with the sport instrument. The motion parameters associated with the detected motion are collected through the embedded motion sensor and analyzed by a motion detection and recognition system. Based on the analysis of the motion parameters, various types of sports performance reports and performance improvement recommendations are generated for users of the sport instruments.

Sensing devices including pliable e-textile pressure sensors are used in gloves intended to be worn against a user's hand, or a portion of a user's hand. Additional sensors, such as accelerometer(s), gyroscope(s) and geo-referencing sensor(s), may be incorporated in electronic devices that interface electronically with the pressure sensors and are mounted on or in proximity to a glove when in use. Systems and methods for storing, communicating, processing, analyzing and displaying data collected by sensor components for remote monitoring of conditions at hand surfaces, position and orientation data, movement data, and the like, are also disclosed. Sensors and sensor systems provide substantially real-time feedback relating to current body conditions, orientation and movement, and may provide notifications or alerts to users, coaches, etc., enabling early intervention when conditions indicate intervention is appropriate.

Die vorliegende Erfindung betrifft einen Rahmen für einen Ballspielschläger mit einem Kopfabschnitt und einem Griffabschnitt, wobei der Rahmen als Hohlprofil ausgebildet ist und Magnesium aufweist und wobei die Wandstärke des Hohlprofils entlang eines Querschnitts durch das Rahmenhohlprofil variiert sowie ein Verfahren zur Herstellung eines solchen Schlägers.
摘要:
Sensor systems for detecting the position and/or trajectory of an object as well as their methods of use are disclosed. In one embodiment, a sensor system may include three or more parallel conductors adapted to be arranged on a ball playing surface. The three or more conductors may be adapted to detect an electrical signal induced in at least two of the three or more conductors by a ball. The sensor system may also include a processor electrically communicating with the three or more conductors that is configured to receive the electrical signal and output at least one of a trajectory and position of the ball.
