Methods for providing track condition information include receiving, at a first mobile track control station, a track condition notification. Such methods further include transmitting, from the first mobile track control station to a second mobile track control station in a network of mobile track control stations, the track condition notification. Such methods further include receiving, at the first mobile track control station from a third mobile track control station, affected track sector data regarding an affected track sector. Such methods further include transmitting, from the first mobile track control station to a first mobile track information station within a first vehicle, the affected track sector data, wherein the affected track sector data is configured to be used by the first mobile track information station to determine whether the first vehicle is within the affected track sector.

A solo pigeon loft may be operated by a single user to provide a plurality of racing pigeons from the solo pigeon loft. The plurality of pigeons from the solo pigeon loft may be used in a pigeon race. The racing pigeons from the solo pigeon loft, therefore allow for a pigeon race without inclusion of racing pigeons from a separate distinct pigeon block.

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 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. The method includes measuring during the race a plurality of intermediate times with an inertial sensor and/or a positional sensor in a wearable device; causing a processing unit in the wearable device to retrieve, based on the intermediate time and on previous races of other athletes, a race profile as non-linear function of time over distance (t=f(d)); and using the retrieved race profile for determining the information.

System and method to automatically control a track timing system for humans and/or animals. One or several users are detected in start and finish areas on one or several tracks and automatically signaled to start by the system. Results such as finish time, start reaction time, false starts, split times, relay exchanges, and such can be calculated. The results can be displayed and distributed, and the system can be configured by a user.

A method for determining split-times in a relay race run using one or more lanes of a running track, where a relay team in each lane carries a respective relay baton, includes, for each lane: (a) periodically determining a location of the respective relay baton, (b) determining, for one or more take-over zones in the lane, respective first times when the relay baton crosses a respective line within the take-over zone, (c) determining a second time when a finish line of the relay race is reached, and (d) determining a split-time for each segment of the relay race, based upon a start time of the relay race, the one or more first times, and the second time.
