A personal transport system is provided including, in an embodiment, an electrically powered vehicle, a companion remote control, and a companion mobile phone application. The vehicle includes an operator-supporting deck, one or more deck-mounted trucks, one or more axle-mounted wheels on each of the one or more trucks, one or more batteries, and a deck lighting system. The one or more batteries power a motor configured to drive the wheels by way of a pulley system, at least one battery of which is disposed under a battery enclosure. The battery enclosure has a first light indicator system, and the companion remote control has a second light indicator system, each of which is configured for communicating with the operator. The deck lighting system includes a light strip of light-emitting diodes disposed in a groove of the deck configured to change state to communicate with the operator or others sharing a road.

A portable boundary system (PBS), which is a complete pre-measured boundary-line system used for sport specific boundary lines/markings. Whether tennis, pickleball, basketball, badminton or other sports requiring boundary lines/markings, the PBS's of the present disclosure allow a single user to accurately set-up and define a sport's court/playing area. Assembly and disassembly of PBS's and pop-up nets takes a fraction of the overall time and cost of traditional court assembly methods. Since PBS's and pop-up nets are portable, they can be packaged efficiently and moved to varying locations. PBS's do not mark or mar gym floors, concrete, asphalt, grass or other hard or soft surfaces. PBS's are made from PVC/Vinyl and are durable and re-usable.

This invention is directed toward a portable and easy to set up retractable cord system with means to allow athletes to move along specified routes and to form space indicators that show zone areas.

A service vehicle with service equipment for performing a predetermined service operation in an operating area, the vehicle comprising positioning means to determine position information for navigating the service vehicle and/or the service equipment; monitoring means to acquire position-dependent operational data of the performing of the service operation in dependence on the position information; and reporting means to communicate the position-dependent operational data to a remote management server. The service vehicle is operable in a first mode, in which the positioning means provides the position information to the monitoring means which acquires the position-dependent operational data using the position information; the reporting means communicates the operational data to the remote management server; and the navigating is performed substantially independently of the position information.

The novel system of the present invention includes a plurality of moveable markers, such as cones, having two visually contrasting indicators useful for physically and visually demarcating activity zones. The markers can be dispersed spatially, such as being placed on the ground or on posts, to demarcate areas, zones, regions or boundaries, for conducting an activity, such as soccer practice. The system is useful to guide, instruct, monitor or constrain the activity of an individual, or object. Alignment of the markers can visually separate one zone from another zone so as to indicate different activities for each zone.

A temporary or permanent safe line projection system comprises a stationary or movable structure that is dimensioned and arranged to be supported by and project upwardly from an athletic field surface (or other surfaces needing delineation). A laser source is supported by the movable or stationary structure and is maintained by the movable or stationary structure at an elevated location relative to the athletic field surface (or other surface needing delineation). This allows the laser source to direct safe optical energy downward upon the field while the movable or stationary structure is maintained substantially in a first orientation relative to the athletic field surface (or other surfaces desiring delineation). A sensing arrangement is operative to to disable the laser source or modulate its output depending upon proximity of users to the system or its output and upon ambient lighting conditions, as the case may be.

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.

Embodiments described herein relate to a system which includes a vertical support, a elevation coupler attachable to the vertical support, and a first outer horizontal member couplable to the elevation coupler to extend from the elevation coupler at an angle substantially perpendicular to the vertical support. The system includes a first inner horizontal member couplable to the first outer horizontal member. The system includes a second outer horizontal member couplable to the elevation coupler and a second inner horizontal member couplable to the second outer horizontal member to form a grid in an elevated position to provide an arrangement suitable for a game. The vertical support is adjustable in length to adjust a height of the grid.

A line striper comprises a sprayer secured to a frame, and a guided wheel assembly rotatably mounted to the frame. The guided wheel assembly includes an adjustment disk with screw notches along its outer diameter, an alignment plate coaxially surrounding and abutting the adjustment disk, alignment screws threaded through the alignment plate to engage screw notches on the adjustment disk, and an antirotation lock. The screws set a rotational alignment of the alignment plate relative to the adjustment disk, and the adjustment disk is coupled via a spindle axle to a guide wheel. The antirotation lock engages a locking feature on the alignment plate, thereby fixing the orientation of the guide wheel relative to the wheeled frame at an angle determined by the rotational alignment.
