Disclosed are various embodiments for a climbing apparatus for pet training and exercise. The climbing apparatus for exercising or training pets may include, for example, a first ramp directly coupled to a second ramp at a coupling point located at a peak of a hill, the first ramp and the second ramp having an angle of incline that is substantially similar, thereby forming a substantially symmetrical and triangular structure. The first ramp and the second ramp can include supports projecting from a surface of the first ramp and the second ramp to facilitate navigation of a path that comprises an incline of the first ramp and a decline of the second ramp. In addition, the supports can render the apparatus free-standing and portable.

A hurdle assist includes a flexible tubular lower section comprising a first length and a first slit along the first length, a flexible tubular upper section comprising a second length and a second slit along the second length, and a flexible rod which is slidably removably coupled with the flexible upper section. Attaching the hurdle assist to a hurdle mimics a flexible hurdle for the runner to practice without fear of injury.

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 resettable breakaway apparatus may include: a housing having an aperture. A plunger may extend through the aperture, and the plunger may be movably coupled to the housing. The plunger may have a plunger head, and the plunger head may be movable between a first position, in which the plunger head is relatively farther from the housing, and a second position, in which the plunger head is relatively closer to the housing. A tensioner may tension or compress the plunger head in the first position. The apparatus may further include a receiver having a receiver head. The housing may be coupled to a first object and the receiver may be coupled to a second object, and the apparatus may be configured to removably couple the objects together by engaging the plunger head with the receiver head so that the plunger head may be positioned between the first and second position.

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.

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.

Disclosed are various embodiments for a freestanding and portable climbing apparatus for pet training and exercise. A climbing apparatus includes a platform being rectangular and supported vertically at each corner by a first post, a second post, a third post, and a fourth post. The first post and the second post are coupled to a first platform foot, and the third post and fourth post are coupled to a second platform foot. A first ramp is coupled to a first end of the platform and a second ramp is coupled to a second end of the platform opposite that of the first end, where the first ramp and the second ramp have an angle of incline that is substantially similar. As such, the climbing apparatus is freestanding, portable, and substantially symmetrical.
