A hockey stick apparatus may include a molded blade structure coupled to the proximal end of a hollow shaft structure. The molded blade structure can include: a top edge spaced apart from a bottom edge by a blade height, a heel spaced apart from a toe by a blade length, a front face spaced apart from a back face, and an optional slot defining an aperture extending through front face and the back face. A stiffness of the blade may vary along the blade height by changing the shape of the blade and changing a quadratic momentum of the cross-section along the blade height.

A wearable training apparatus has a vision-control assembly for engaging a user's face about the user's eyes. The vision-control assembly has a see-through area about the user's eyes and an opaque area surrounding the see-through area at least on a temporal side and an inferior side thereof. The opaque area is for substantially blocking at least major portions of the natural monocular vision-areas of a natural field of vision (FOV) of the user's eyes, said natural monocular vision-areas being peripheral to a natural binocular vision-area on respectively temporal sides. The see-through area is for forming a reduced FOV about a gaze direction. The reduced FOV has a span encompassing at least a major portion of the natural binocular vision-area of the natural FOV of the user's eyes about the gaze direction thereof, said natural binocular vision-area being at an angular center of the natural FOV.

Training equipment includes a hollow shaft having a sidewall defining an internal cavity and at least one polymer material filling at least a portion of the internal cavity. The polymer material may fill the entire internal cavity of the hollow shaft. The polymer material may be a visco-elastic polymer material or polyurethane. A spacer or a filler may fill at least a portion of the internal cavity. A method of making weighted training equipment with a hollow shaft having a sidewall defining an internal cavity may include injecting a curable composition into at least a portion of the internal cavity. The method may further include curing the curable composition into a polymer material.

Systems and methods for tracking a sports ball assembly in real time during a sporting event are disclosed. A structure of the sports ball assembly is also disclosed. The sports ball assembly comprises at least one electronic circuit embedded or attached to a sports ball. The sports ball assembly is in network communication with a processor via at least two receivers within a sports arena. The sports ball assembly generates and transmits UWB data packets comprising movement-related data for the sports ball assembly in real time at a predetermined rate. The at least two receivers receive the UWB data packets and transmit to the processor with time stamps. The processor is operable to determine a movement of the sports ball assembly based on the UWB data packets and the time stamps received from the at least two receivers.

A hockey goalkeeper leg pad includes a core, a skin covering the core, a lateral leg flap and a medial leg flap defining a leg channel, and a lacing member. The lacing member includes lower tabs and upper tabs. The lower tabs and the upper tabs each defining apertures with a front inner surface of the skin covering the core, and the lower tabs and the upper tabs being attached to the front inner surface at lateral outer ends thereof. The upper tabs are laterally offset outward of the lower tabs relative to a longitudinal centerline of the lacing member. A lace extends through the lower apertures and the upper apertures, as well as through the core to secure the core to the lacing member.

A hockey puck is disclosed including an internal signal transmitter enabling instantaneous identification of its position as it moves around. The hockey puck includes two molded subcomponents, which encapsulate the signal transmitter. The signal transmitter includes driver electronics and a number of signal transmitters which together generate and emit an electromagnetic signal. The electromagnetic signal is emitted by a plurality of diodes mounted in cavities in the subcomponents, for example around an outer circumference of the hockey puck and through a top and bottom surfaces of the hockey puck. The hockey puck is alternatively formed of a material that allows electromagnetic radiation to be emitted through the subcomponents, and the diode cavities omitted.

Protective shoulder pads, such as the type worn for playing ice hockey, including a central panel configured to cover a portion of a chest of the wearer and defining a centerline extending centrally therethrough, and two side panels partially overlapping the central panel and each disposed on opposite sides of a centerline of the central panel. Each of the side panels is rotatable relative to the central panel about a rotation axis located proximate an upper end of each of the side panels, so as to adjust a width of the protective shoulder pad which is defined between opposed outer lateral edges of the side panels. The side panels are securable to the central panel at a plurality of attachment points to maintain a selected width of the adjustable shoulder pad.

A system simultaneously tracks multiple objects. All or a subset of the objects includes a wireless receiver and a transmitter for providing an output. The system includes one or more wireless transmitters that send commands to the wireless receivers of the multiple objects instructing different subsets of the multiple objects to output (via their respective transmitter) at different times. The system also includes object sensors that receive output from the transmitters of the multiple objects and a computer system in communication with the object sensors. The computer system calculates locations of the multiple objects based on the sensed output from the multiple objects.

A hockey puck is disclosed including an internal signal transmitter enabling instantaneous identification of its position as it moves around. The puck includes two molded subcomponents, which encapsulate the signal transmitter. The signal transmitter includes driver electronics and a number of signal transmitters which together generate and emit an electromagnetic signal. The electromagnetic signal is emitted by a plurality of diodes mounted in light pipes enclosed within cavities in the subcomponents that extend to outer surfaces of the hockey puck components. The puck includes two subcomponents that are attached via complimentary sets of concentrically arranged wedges.
