An adjustable step trainer including two straps and more than one slat through which the straps are passed. Each end of the slat has a fixing section through which the strap is passed. A press unit is disposed in a chamber of the fixing section for pressing and fixing the strap.

A hurdle has a crossbar and a pair of vertical legs. The hurdle is designed to give way or collapse when the crossbar is struck by a user to minimize the risk of injury and thereby decrease the user's fear of injury. This is done either by splitting the crossbar into separate left and right sections, or by splitting each of the legs into separate top and bottom sections. This permits the separate sections to break apart from an aligned, end-to-end orientation which they possess in an operative position of the hurdle into a nonaligned orientation after the hurdle has given way or collapsed. An elastic member connects the separate sections and urges the sections back into their aligned, end-to-end orientation when a user picks the sections of the hurdle up and resets the hurdle.

A continuously height-adjustable jump cup attachment bracket for a sporting fence to support a rail includes a jump cup carried on a bearing plate that frictionally engages a support post provided with a channel and a clamping means associated with the bearing plate. The clamping means may be selectively engaged to set the height of the rail of the fence and also to be displaced from such setting in the event of accidental downward movement of the rail in relation to the post.

An exercising device includes a main frame, a pivot bar pivotally mounted on the main frame, a stop block mounted on the pivot bar and rested on the main frame when the main frame approaches the pivot bar, two rocking bars mounted on the main frame, and two elastic members each biased between the main frame and the pivot bar. Thus, the longitudinal bar of the main frame is rested on the stop block, thereby preventing the main frame from being entirely rested on the ground due to an excessive rotation, and preventing the user's back from being injured due to excessive bending so as to protect the user's safety.

A masquerading detection system includes: an imaging unit (2) that obtains a first image by imaging an inspection object (12) from a first angle, and a second image by imaging the inspection object from a second angle which is different from the first angle; a unit (101) that detects first feature points from the first image, obtains first feature point coordinates of the detected feature points, detects second feature points from the second image, and obtains second feature point coordinates of the detected feature points; a unit (104) that obtains transformed coordinates by performing a plane projective transformation for the second feature point coordinates from the second image to the first image; and a unit (105) that determines that masquerading has been attempted when the difference between the transformed coordinates and the corresponding first feature point coordinates is equal to or smaller than a predetermined value.

A single position motocross starting gate having a pair of U-shaped members pivotally connected together at one end of each U-shape. A releasing mechanism having a normally extending pin is positioned on one of the U-shaped members to pivotally support in an interference relationship the other U-shaped member in a first angular position relative to the one U-shaped member. Releasing means such as a lanyard is connected to the releasing mechanism to slideably move the pin causing the other U-shaped member to drop and be in line with the one U-shaped member. When this happens, the rider on the motocross motorcycle can move forward over the two U-shaped members. Typically another individual other than the driver pulls the lanyard.

An exercising device includes a main frame, a support frame pivotally mounted on the main frame, and an arc-shaped rocking bar fixed on the main frame. Thus, the rocking bar is arc-shaped so as to satisfy the ergonomic design, so that the user can operate the exercising device in a comfortable and safe manner. In addition, the user can operate the exercising device easily and conveniently, thereby facilitating the user operating the exercising device.
