摘要:
An apparatus and method for improving physical coordination and ability to react to moving and stationary objects is disclosed herein. A pair of voltage controlled liquid crystal lenses (14, 16) are mounted in a support frame (12) which is worn by a user in the same manner as conventional eyeglasses. The lenses (14, 16) can be electronically pulsed between an opaque state and a transparent state. Further, the lenses (14, 16) scatter background light in their opaque state rather than block the light so as to provide a generally constant level of contrast and brightness. This prevents pupil dilation changes when switching between the transparent state and the opaque state. Each lens can be made to pulse from an opaque state to a transparent state and then back again, and can be controlled independently or in synchronization. In operation, the user adjusts the control unit (18) to pulse the lenses (14, 16) at a high speed. An object is then viewed through the lenses and an appropriate response is made. As the user's proficiency increases, the user decreases the pulse rate and continues to react to the object. Reduction in pulse rate is continued until the desired level of reaction proficiency is achieved. When the apparatus is eventually removed, the user will be able to react to objects moving at higher speeds with greater proficiency. Additionally, in the case of both moving and stationary objects, the user's ability to concentrate will be increased.

Die Erfindung bezieht sich auf eine Einrichtung zum Einüben der Schlagbewegungen der Sportler mit einem Tragrahmen, einem Ball und einer Einheit zur Rückführung des Balls in die Ausgangsstellung. Die Rückführungseinheit weist einen federnden Spanndraht auf, der mit seinem einen Ende mit dem Rahmen verbunden ist. In der Einheit zur Rückführung des Balls ist ein Stab eingebaut. Das eine Ende des Stabs ist am Rahmen befestigt und zwar derart, dass mindestens zwei Bewegungsfreiheitsgrade sichergestellt werden. Das andere Ende des Stabs ist mit dem Ball verbunden, wobei das andere Ende des Spanndrahts mit dem Stab gekoppelt ist.

The invention provides a method of ball game motion recognition, an apparatus for the same, and a motion assisting device. The method comprises: obtaining motion parameters corresponding to each sampling time for a motion; extracting feature points according to predetermined feature point recognition tactics utilizing the motion parameters obtained, in which the feature point recognition tactics comprise recognition tactics of at least three types of the feature points, comprising: power-assisting path early stage corresponding feature point, motion top point corresponding feature point, and ball hitting time corresponding feature point; and recognizing the motion as a predetermined ball game type if the feature points extracted satisfy feature point requirements of the predetermined ball game type.

A trampoline (10) includes a bed (14), a base frame (12), a bed suspension assembly (16) that resiliently couples the bed (14) to the base frame (12), and a plurality of legs (20) that are connected to the base fame (12) so as to maintain the base frame (12) above a surface (36). The base frame (12) includes a first side frame (22), a second side frame (24), a first end frame (26), and a second end frame (28). The plurality of legs (20) includes (i) a first leg (20A) that is secured to the first side frame (22) and the first end frame (26), (ii) a second leg (20B) that is secured to the first side frame (22) and the second end frame (28), (iii) a third leg (20C) that is secured to the second side frame (24) and the second end frame (28), and (iv) a fourth leg (20D) that is secured to the second side frame (24) and the first end frame (26). The trampoline can further include a backstop frame (244A) that is mounted on the base frame (12) and that extends in a generally upward direction away from the base frame (12). The backstop frame (244A) includes a substantially straight first lower support member (250) that is coupled to the base frame (12), a substantially straight second lower support member (250) that is spaced apart from the first lower support member (250) and that is coupled to the base frame (12), and a substantially arch shaped upper support member (252) that extends from near a distal end (250B) of the first lower support member (250) to near a distal end (250B) of the second lower support member (250).

The invention relates to sports training devices and can be used for training a volleyball spike-motion. The inventive device comprises a bearing frame, a ball and a unit for returning the ball to the initial position thereof which is provided with an elastic spreader connected to the frame by one end thereof, a rod whose one end is fixed to the frame in such a way that it has at least two degrees of freedom, whereas the second end is connected to the ball and the second end of the spreader is connected to the rod. The frame is also provided with the rod-arresting unit. Said device enables the ball to be moved along an arc of a circle, thereby increasing the quality of the spike-motion training.
