The present invention relates to an unmanned air vehicle racing system and method. The unmanned air vehicle racing system includes: at least one unmanned air vehicle which transmits data on an image to a server; a track which includes: a plurality of obstacles which detects time information, speed information, direction information, and altitude information, and which transmits data on the detected information to the server; and a plurality of guide bars which is located among the obstacles, and which indicates traveling directions; the server which processes the data received from the unmanned air vehicle, and which calculates the score of the unmanned air vehicle based on the data, received from the plurality of obstacles, according to a set algorithm; and an electronic scoreboard which receives the processed data and the calculated score from the server, and which displays a 2D or 3D image and score and ranking information.

An example system for racing aircraft systems includes: a plurality of autonomous synchronized unmanned aircraft systems configured to form a swarm at a race course through which the aircraft systems are to navigate; and a controller configured to be operatively coupled to at least one unmanned aircraft system of the swarm, the controller configured to control the swarm to form an element of the race course.

A hurdle structure includes a transverse bar, two upright poles, two support rods, and a plurality of hinge mechanisms. Each of the hinge mechanisms is mounted between the transverse bar and each of the two upright poles, and between each of the two upright poles and each of the two support rods. Each of the hinge mechanisms includes a first pivot member, and a second pivot member pivotally connected with the first pivot member. Each of the hinge mechanisms further includes an adjusting unit mounted between the first pivot member and the second pivot member. The adjusting unit includes a locking member and a positioning member. The locking member is provided with a plurality of grooves. The positioning member is provided with a projection positioned in one of the grooves of the locking member.

Disclosed are various embodiments for a freestanding and portable climbing apparatus for pet training and exercise. A climbing apparatus includes a platform having a top surface that defines a walking surface for a pet. The climbing apparatus includes a first post, a second post, a third post, and a fourth post having top ends coupled to a respective corner of the platform that raise the platform from a ground surface such that a top surface of the platform is an elevated surface. A first ramp is coupled to the first end of the platform supporting the platform at the first end, and a second ramp is coupled to the second end of the platform opposite that of the first end supporting the platform at the second end. One of a first platform foot, a second platform foot, a first ramp foot, and a second ramp foot are formed of polyethylene.

Device for training people to a preferred posture during normal gait comprising of: at least a base for stabilizing at least one rail or post coupled to said base at least one gait regulating component, which will be arranged perpendicularly with respect to said rod or post and parallel to the floor surface, with said gait regulating component provided for defining an obstacle during the normal gait of a user to impose on the latter a predetermined movement of the foot, knee, and hip, facilitating the maintenance of the user's bust erected in a position of equilibrium, with the consequent lengthening of the pushing leg, the gradual transition of the weight of the user's body by the supporting foot posterior to that of the advancing leg, and the oscillation of the arm forward opposite to the lower limb that moves, with a final effect of a steady pace.

A hurdle with a riser assembly having a gate board attached to movable gate tubes that telescope upon uprights and with a cross support between the trailing ends of the legs has a height adjustment system that includes a pedal in the cross support. Depressing the pedal retracts spring loaded posts to allow a user to hold and move the gate board up or down with the hands.

Disclosed are various embodiments for a freestanding and portable climbing apparatus for pet training and exercise. A climbing apparatus includes a rectangular-shaped platform having a first end, a second end, and a plurality of corners. Posts having top ends are coupled to a respective one of the corners of the rectangular-shaped platform that raise the rectangular-shaped platform from a ground surface. A first ramp and a second ramp are coupled to ends of the rectangular-shaped platform. A first platform foot is coupled to bottom ends of the first post and the second post, and a second platform foot is coupled to bottom ends of the third post and the fourth post. Ramp sides are positioned along and protrude above a first side of the first ramp, a second side of the first ramp, a first side of the second ramp, and a second side of the second ramp.
