The present disclosure provides a system for conditioning and training, generally comprising a floor portion and at least one guide within a line of sight of the floor portion. The guide is configured to display training programs for a user to use to improve sports skills, such as hockey skills for example. In an embodiment, the floor portion has RFID tags to determine where a puck or other object is located. In another embodiment, the system has an apparatus to determine, verify or display a puck location. The apparatus can be either a camera or an AR unit such as glasses. Based on information provided and received, the system can tailor exercises for a user and provide enhanced statistics to improve skills.

A roller mounting apparatus for an in-line roller skate blade comprises a body having a footware connector portion, a spacing portion adjacent the footware connector portion and a roller mounting portion adjacent the spacing portion. The roller mounting portion has roller mounts for mounting a plurality of rollers in tandem spaced apart positions such that contact points on outer surfaces of the rollers will lie on a first common curved line having no portion with a radius of curvature more than about 10 m, so that a contact point on a surface of a roller immediately adjacent to any given roller is spaced apart between about 0.1 mm to about 13 mm from a line tangent to the curved line at a point defined by the contact point of the given roller. A roller blade comprising the roller mounting apparatus is also disclosed. There is also disclosed a method of sharpening an outer circumferential surface of a rotatable roller of a roller blade by causing an outer circumferential surface of a rotating grinding implement to contact the outer circumferential surface of the rotatable roller at a contact point such that a grinder plane containing the contact point and a rotation axis of the rotating grinding implement is disposed at an angle to a roller plane containing the contact point and a rotational axis of the roller. Also disclosed is a method of sharpening an outer circumferential surface of a rotatable roller by causing an outer circumferential surface of a rotating grinding implement to contact the outer circumferential surface of the rotatable roller such that the rotating grinding implement tends to drive the roller in a first direction of rotation while causing a contact surface of a rotating drive wheel to contact the roller to cause the roller to rotate in a second direction against the first direction of rotation to cause relative movement between the roller and the outer circumferential surface of the grinding implement.

A device for storing and dispensing hockey pucks includes a box defining an interior capable of receiving a plurality of the hockey pucks, wherein the box comprises a first door opening and a second door opening disposed approximately perpendicular to the first door opening, a first door pivotably attached to the box within the first door opening, wherein, when closed, the first door encloses the interior when closed, and wherein, when open, the first door forms a ramp for receiving the hockey pucks through the first door opening and into the interior, and a second door pivotably attached to the box within the second door opening, wherein, when closed, the second door encloses the interior, and wherein, when open, the second door dispenses the hockey pucks from the interior through the second opening.

An apparatus for a game can include a first disk configured to slide on a court; a second disk; a jack configured to slide of the court, a measuring device, a scorecard, a signaling device, a court brush and/or a court scraper. The apparatus can be used to play icebocce.

The curling broom head is composed of a fabric section, flexible section, lower body, upper body, and a stem or stem assembly that is used to attach the broom head to the broom handle. The fabric section is a stand-alone piece of fabric that can easily be removed and replaced by the user. The fabric section is wrapped around the flexible section and lower body and is secured into place and ready for game play when the lower body is attached to the upper body. At any time, the curling fabric may be easily replaced by separating the upper and lower bodies, removing the old fabric from the lower body and replacing it with new fabric.

The curling broom handle is an elongated member that is attached to the broom head on one end. A removable device(s) is attached or secured to the broom handle at a desired height and provide an easier profile to grip and/or extra surface area to exert downward force. A removable device is attached or secured to the end of the broom handle to provide an increased surface area to exert downward force on the broom handle.

A system and method for measuring motion properties of a movable object, such as a sporting device, wherein the movable object has an embedded magnetized unit creating a magnetic field. A measurement device, having a first magnetic field sensor positioned a known distance away from a second magnetic field sensor, is positioned in the vicinity of the movable object's trajectory, whereby the first and second magnetic field sensors output signals when the movable object passes within their respective proximities. A control module, that is responsive to the output signals created by the magnetic field sensors, is configured to record the times of output signal events. The control module is further configured to calculate motion properties, such as the speed and rate of spin, of the movable object based upon the recorded times of various sensor output events and the known distance between the first and second magnetic field sensors.
