A method of installing a binder-based overlay system may include contacting a layer of geotextile fabric to a surface of a substrate and applying a primer layer to a surface of the geotextile fabric. Two or more binder layers including infill particles may be applied over the primer layer. A resurfacer layer followed by one or more color layers may be applied over the two or more binder layers. The primer layer, one or more binder layers, resurfacer layer, and two or more color layers may cure upon application to form a monolithic layer upon the substrate.

The invention relates to a system for variable marking of a playing field (1), comprising at least two marking devices (2) designed as laser projectors, an analysis device designed to analyse a calibration pattern (3) projected onto the playing field (1) by means of a marking device (2), as well as designed to determine a distortion function from the calibration pattern (3), a control device designed to determine the position of a marking pattern (4) on the playing field (1), and a transformation device designed to apply the distortion function to the marking pattern (4) in order to obtain a target marking (5). The invention further relates to a method for variable marking of a playing field (1).

A self-propelled robot unit including a navigation system and movement items for positioning of the robot unit on an even base and a system for impacting predefined areas of the base during the unit's movement between two points on the base is provided. The robot unit's system for impacting predefined areas of the base includes at least one effect unit provided by an outer side of the wheels in relation to the center axis, but upwards one of the driven wheels. An embodiment also relates to a method for creation of a plan for the robot unit's movements and placement of markings for a ball game field.

A sports field marking assembly and method of marking creates a boundary reference point and field lines on a field or for coaching. The assembly provides a marker anchoring device that is loaded with field markers. The marker anchoring device comprises a translatable handle coupled to a spring-loaded piston that discharge the field markers into the surface of the sports field. Bristles couple to a rear end of the marker body for visibility above the surface of the field. A tape canister couples to the marker anchoring device to dispense a measuring tape. The measuring tape couples to the field markers, serving to delineate the boundaries and lines on the field. Multiple aligners anchor into the sports field to retain the measuring tape in the formed patterns. The aligners have collapsible and moveable guide posts that can be selectively raised to guide the measuring tape though the chosen guide posts.

Presented is an apparatus and system for an artificial turf system. The artificial turf system includes a backing layer having a plurality of fibers extending therefrom. The artificial turf system further includes a plurality of impact sensors located at least partially on, in, and/or beneath the backing layer, wherein the plurality of impact sensors are operable to detect a force or pressure applied to the backing layer.

A line marking apparatus comprises a body (21) mounted so as to be mobile, a line marking head (29) movable relative to the body, and means (35, 37, 41, 43) for determining the distance travelled by the apparatus from a determined point.

A method for playing basketball in a court having first and second sidelines and a basket located at each opposed end of the court on a long axis of the rectangle includes providing a reduced court with third and fourth sidelines within the first and second sidelines, and a central line (fifth line) along a length of the court, wherein the third and fourth sidelines define an area between 70% to 80% of a regular court; and selectively playing a first game type based on the central line with two classes of players with between 4 and 16 players or playing a second game type inside the third and fourth sidelines with 8 or less players.

A method for marking artificial turf mats that allows for the obtaining of artificial turf mats with indelible motifs on any of the surfaces of said mats, comprising positioning means for at least one mat and marking means applicable onto at least one surface of said mat, so that said marking means are capable of producing at least one motif onto the surface of said mat.

A sports detection and reporting system that locates the players and the ball to determined if certain play criteria have been met. The system also displays on the field detected locations relevant to the players and the play in real time.

Device (1) for showing a marking (A) in the form of a distance to be observed between a game apparatus (15), in particular a football, and participants on a playing field (22) of a sports facility (2), having a display device (3) for projecting light beams (L) representing the marking (A) onto the playing field (22), wherein the projected light beams (L) display the distance to be observed and can be projected in the shape of a circle, at least in sections, in particular at a distance of 9.15 m around the game apparatus (15) on the playing field (22), wherein the display device (3) is jointly movable with a transport device (8) that is movable above the sports facility (2).
