摘要： 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.

摘要： 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.

摘要： We generally describe an audio-based line fault detection system for a sports game. The audio-based line fault detection system comprises one or more audio sensors (102) for sensing an audio signal generated by a sports gaming device bouncing off a sports field. The sports field comprises surface modifications applied to a line and/or an area adjacent to the line on the sports field such that the generated audio signal is dependent on whether or not the sports gaming device bounces off the sports field where the surface modifications are applied. The detection system is configured to generate a sound profile from the audio signal sensed by the one or more audio sensors (102). The detection system is further configured to identify a bounce type based on the sound profile, wherein the bounce type is defined by whether or not the sports gaming device has bounced off the sports field where the surface modifications are applied.

摘要： Provided is a water track marker (1) for marking a sports track, such as a water ski track, on a water surface (20). The water track marker comprises at least a first marker ejector (11) configured to eject marker projectiles (2) towards the water for creating an instant marking (3) on the water surface (20) upon impact with the water surface (20). Provided is also a method for marking a sports track and a towing boat comprising said water track marker.

摘要： Methods and apparatus are discussed for an electric powered personal transportation vehicle with electric motors powered by one or more batteries. A battery pack storage enclosure i) contains a set of pocket cores. The first battery pack storage enclosure has a rigid internal structure that has a set of pocket cores that hold the battery cells in place and ii) contains a metal mid-plate that functionally transfers thermal heat rapidly through a metal mass of the metal mid-plate to smooth out spikes of local temperatures when an initial battery cell overheats and fails in order to minimize the heat from the initial battery cell failure from propagating and causing a neighboring battery cell to also fail from the heat.

摘要： A local coordinate system in which the turfed area is digitized, and a marking area is divided into elementary cells to form a matrix, and the pattern to be marked is broken down into a mosaic of pixels associated with the elementary cells of the matrix. Next, for each elementary cell of the matrix, tasks to be performed by the marking devices are determined according to a value of the pixel associated with said elementary cell, to mark the pattern to be marked on the marking area; and the movement of the vehicle over the turfed area is controlled so as to cover all of the elementary cells, and the marking devices are controlled so as to perform the tasks to be performed in each elementary cell.
