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.

Methods and apparatus are discussed for an electric-powered personal transportation vehicle with a composite board to support a weight of a user, one or more wheels driven by one or more electric motors, where the electric motors are powered by one or more batteries. The composite board includes a heterogeneous mix of individual components making up the composite board. The composite board includes i) a spine of the composite board made of a hardwood material connected to ii) sides of the composite board made of a vibration-dampening, high-density, foam.

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.

A line striper having a spray control system includes a spray gun, a lever, first and second cables, a manual actuator, and an assisted control. The lever is configured to move between a spray position and an inactive position. The first cable is mechanically linked to the lever. The manual control is mechanically linked to the first cable and configured to pull the first cable rearward to move the lever into the spray position. The second cable is mechanically linked to the lever. The assisted control is configured to pull the second cable rearward to move the lever into the spray position. The lever is independently moveable relative to the first and second cables such that movement of the lever caused by the first cable does not compress the second cable and movement of the lever caused by the second cable does not compress the first cable.

A basketball goal system comprising a backboard assembly and suspension frame affixed to the back surface, a suspension structure connected to the suspension frame of the backboard and a goal indication system which interfaces to at least one of the suspension structure or backboard to cause an indication (of various colors) to be presented via the suspension system and/or the backboard which indication relates to the shot points associated with a shot attempted at the goal. The goal indication system causes presentation of a cue on a front surface of the backboard, which cue is of a color corresponding to shot points. The backboard elements and light emission of the suspension frame can be controlled synchronously or asynchronously.

A ring for a fighting sport has a circular fighting area defined by a plurality of circular fence rings that are held up by posts. Shock absorbers connect the fence rings to the posts. Position markers are provided to indicate the starting positions of the participating fighters at certain points during the bout.

An athletic chalk comprising plaster of Paris, magnesium carbonate and activated charcoal, having relative proportions of materials of approximately 71-75% plaster of Paris, 19-23% magnesium carbonate and 10-2% activated charcoal, and a method for producing same.

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.

A real-time measurement and marking apparatus is provided. The disclosure providing a portable marking device comprising: a housing including a main housing structure and a can cover, the main housing structure having a front open end, a rear nozzle end, a top surface, a bottom surface, and a pair of opposing side walls, wherein at least one of the side walls defines an aperture, the can cover having a rear open end, a front closed end, the can cover extending at the rear open end to selectively engage with the aperture defined by at least one of the side walls releasably securing a spray can within the housing; a nozzle member positioned at the rear nozzle end of the of the main housing structure; an optical measuring apparatus for real-time measuring of a distance between a point of focus and the portable marking device activated by one or more buttons.

The invention is intended for the organization of an automated process for spraying of liquid means of chemical treatment from unmanned vehicles, for example, in precise farming systems. The use of a replaceable, marked and hermetically sealed liquid subsystem in the spray device of the invention, along with an integrated self-diagnosis system, using compressed gas energy and a pressure regulator instead of standard pumps, reduces the weight of the spraying device, improves spraying accuracy, ensures personnel safety and accounting of the accumulated life resource of the main units of spraying devices. All this in combination enables to create fully automated spraying systems.
