A system for judging or determining position or posture, and/or a time on a line crossed by at least one competitor or racer in a sporting competition, includes at least an apparatus for taking a photograph when an intermediate line or a finishing line of the competition is crossed, the image of the photofinish type taken defining an input of the system, and a processing unit connected to the photographic apparatus to combine the photofinish image received with a processing of an algorithm using artificial intelligence for automatically placing one or more cursors on the photofinish image.

A method and a controller for tracking moving objects in an environment of an event, each moving object including an associated identity marking and different key portions. The controller receives images from a camera and identifies moving objects in the received images and separates these moving objects from a background of the environment, determines position coordinates of the associated identity markings and the different key portions of each moving object, receives a first and a second set of data points representing position coordinates in a field of view of a first and a second LIDAR device, wherein the field of view of the second LIDAR device is partly overlapping the field of view of the first LIDAR device, separates data points representing the moving objects from data points representing a background for each of the first and the second set of data points, calculates a weighted mean value for the position coordinates of the moving objects and reconstructs the position in the environment and the associated identity marking for the moving objects in a particular point of time.

A catch fence system for use at a race track having a retaining wall. The catch fence system includes first and second frame members with each having a lower front member with a mounting bracket adapted to connect the lower front member to the retaining wall. A first support ring is affixed to the lower front member of the first frame member and a second support ring is affixed to the lower front member of the second frame member. A first front cable extends through the first and second support rings. A first stop block is affixed to first front cable to the outside of and a distance L1 from the first support ring and a second stop block is affixed to the first front cable to the outside of and a distance L2 from the second support ring, wherein the distance L2 is greater than the distance L1.

A method for providing at least one of the following information to an athlete during a race such as a running or a cycling race: a race time prediction—a probability to achieve a target time at the end of the race; and/or an indication whether the pace followed by the athlete is too fast, adequate or too slow in order to achieve a target time, said method comprising measuring during said race a plurality of intermediate times with an inertial sensor and/or a positional sensor in a wearable device; causing a processing unit in said wearable device to retrieve, based on said intermediate time and on previous races of other athletes, a race profile as non-linear function of time over distance (t=f(d)); using the retrieved race profile for determining said information.

A roller assembly for smoothing an expanse of granular media such as golf bunker sand, snow, horse race track dirt, or other media. The assembly has one or more rollers having a longitudinal axis. Each roller includes wires spaced from the axis to define a roller surface. Each wire is resiliently flexible to distort inwardly in response to force of contact on, and to recover during release of force from, the granular media as the roller rotates about the axis on the granular media. A shaft extends along the axis of the roller assembly between the arms of a yoke with a handle extending therefrom. As the roller surface traverses the media, at least some of the media is flung outwardly of the roller, smoothing the expanse. The roller assembly may be manually operated or may be towed behind a towing apparatus.

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.
