Disclosed herein is a light emitting device including one or more light emitting diodes to primarily emit light having different wavelengths in the wavelength range of ultraviolet rays and / or blue light, and a wavelength-conversion means to convert the primary light into secondary light in the visible light wavelength range. The light emitting device of the current invention has a high color temperature of 2000 to 8000 K or 10000 K and a high color rendering index of 90 or more, thus easily realizing desired emission on the color coordinate system. Therefore, the lighting emitting device is applicable to mobile phones, notebook computers, and keypads or backlight units for various electronic products, and, in particular, automobiles and exterior and interior lighting fixtures.

A disclosed device provides a trajectory detection and feedback system. The system is capable of detecting one or more moving objects in free flight, analyzing a trajectory of each object and providing immediate feedback information to a human that has launched the object into flight, and / or one or more observers in the area. The feedback information may include one or more trajectory parameters that the human may use to evaluate their skill at sending the object along a desired trajectory. In a particular embodiment, a non-intrusive machine vision system that remotely detects trajectories of moving objects may be used to evaluate trajectory parameters for a basketball shot at a basketball hoop by a player. The feedback information, such as a trajectory entry angle into the basketball hoop and / or an entry velocity into the hoop for the shot, may be output to the player in an auditory format using a sound projection device. The system may be operable to be set-up and to operate in a substantially autonomous manner. After the system has evaluated a plurality of shots by the player, the system may provide 1) a diagnosis of their shot consistency, 2) a prediction for improvement based upon improving their shot consistency and 3) a prescription of actions for improving their consistency.

A method and system for improving the effectiveness of coaches and video game designers for games like soccer, American football, basketball, lacrosse or ice hockey by using RF technology and software. A base station is equipped with a computer programmed with algorithms to track the players and game equipment and thereby produce data of interest to a coach or game designer.

A method and apparatus for a physical training device is provided to accommodate one or more athletes during support of a plurality of independent training scenarios for each athlete. The physical training device provides a plurality of training stations, where each training station may be specific to martial arts training activities, or may be generalized to facilitate training that is effective for a plurality of other sporting disciplines. The physical training device provides removable casters that facilitate maneuvering and reconfiguration of the physical training device. Lifting devices may also be configured along the bottom surface of the physical training device so as to provide a mechanism whereby the casters of the physical training device may be lifted off of the surface that is supporting the casters. Two or more physical training devices may be interconnected so as to provide a localized cluster of physical training devices.

A variable stackable ramp system for forming ramp assemblies for providing challenging obstacle courses including ones for aerial lift for sport jumping with skateboards, inline skates, bicycles and the like. The ramp system includes ramp modules of at least two different configurations with one being an inclined ramp module having an inclined upper riding or support surface and a straight ramp module having a generally horizontal straight upper riding or support surface. The ramp modules are adapted to be interconnected horizontally and vertically in a variety of orientations to provide ramp assemblies of selectively different overall configurations.

A device for mastering skate board tricks and maneuvers comprises a frame. The frame has a top and the frame is adapted to rest on a support surface. A spring board is suspended from the frame by stretchable straps. A foot deck is rotationally secured to the spring board and is secured to the spring board to limit or eliminate relative vertical motion between the spring board and the foot board.

Aspects of this disclosure relate to systems and methods for conducting sport-specific activities. Illustrated systems may be adjustable to permit a performance of different sport-specific activities. Further aspects relate to using sensor data to evaluate a user's performance and determine sport-specific fitness parameters. Various fitness parameters may measure reactive agility and / or the physiological state of the user, such as when in an exhausted state. Illustrated systems may have structures with an output device and a sensor. The structure may include a vertically-arranged planar surface to form a wall. Several structures may be configured to form a boundary. The boundary may be automatically adjustable, for example, depending on one or more specific fitness routines to be implemented. Calculated fitness parameters may be visually mapped on the structures of the system.

An automatic ground marking apparatus including a carriage (1) responsive to carriage control signals for traversing the ground (5), the carriage having a controllable steering and drive system, a controllable marking system and a position determining system (6) arranged to determine the position of the carriage. The ground marking apparatus further includes a processor (8) responsive to the position determining system and operatively executing a software product for generating the carriage control signals to cause the carriage (1) to mark out a predetermined sign (14) on the ground. The position determining system (6) suitably employs a laser beam (4) and reflective tracking prism (2), and the predetermined sign may be defined by data points stored in a file (9) accessed by the processor (8) (FIG. 1).

A filled artificial turf includes a plurality of filled artificial turf sections which can be disconnected, rolled up and stored and then later unrolled and reconnected, thereby to enable a facility to accommodate a wide variety of sporting and non-sporting events, with no adverse effects on the playability of the turf. Each of the sections includes a backing, fibers secured to the backing, and a particulate fill with the fibers being of sufficient density and texture so as to substantially hold the particulate fill to the backing during rolling and unrolling. The sections also include hook and loop fasteners along the edges thereof, to facilitate simple and cost-effective connection and disconnection of the sections.

A redundant array pumping system and control system is provided for water rides for ensuring continuous and non-disruptive supply of water.
