A hockey puck (1) comprising an accelerometer (101) arranged in a recess (5) of a puck body (3). The accelerometer (101) is configured to measure the acceleration of the hockey puck (1) in at least one direction in x-y-z coordinates. The hockey puck further comprises a power supply (25) and a control unit (109) configured to read sensor input from the accelerometer (101) and to provide a control unit output based on said sensor input.

A toy gel ball firearm comprises internal LED's that selectively flash concurrently with firing. The toy may include a foldable shoulder stock, a trigger and trigger guard, an elongated integral barrel, and a receiver that mates with a magazine containing a plurality of hydrated gel balls to be fired. The LED's are disposed near the front of the toy, behind translucent panels. Circuits provided for actuating one or more LED's either sequentially or concurrently may be connected electrically to the OEM triggering mechanism associated with contemporary toy. The illumination system is “off” when the toy gun is on “safety”. With semi-automatic shooting, the LED's are blinked with each shot. LED illumination is constant in the full auto mode. The illumination system can be employed with or retrofitted to a variety of projectile-firing toys powered by internal batteries. Aesthetic lighting effects are maximized with a translucent housing for the toy.

A bag toss game includes a game board with a target opening, sometimes known as corn hole. A pair of legs are pivotally mounted to the game board to support the game board at an angle relative to a support surface. A stowable accessory stand based on a pair of parallel sidebars is connected at upper ends by a perpendicular crossbar. The accessory stand is movable between a predetermined vertical angle position and a stowed position defined within the game board. The lower ends of the sidebars are mounted to the pair of legs. A shelf may be pivotally mounted to the accessory stand. The shelf is movable from a playing position parallel to the support surface to a stowed position parallel to the sidebars. A retention assembly may include a pair of supports extending from an end of the game board to the sidebars

This document relates to a multi-function golf training aid for square alignment. An apparatus for golf comprising: a base with a lower surface and an upper surface, the lower surface is substantially planar and having a length and a width, the lower surface includes a groove, in a tunnel shape, across the width to allow a golf alignment stick to fit within the groove while remaining part of the lower surface is resting on a golfing surface; an adjustable vertical member with a near end and a distal end, the near end is affixed to the upper surface of the base and the adjustable vertical member rises in an upward direction away from the lower surface of the base, and a holder affixed to the adjustable vertical member at a lower surface of the holder, wherein an upper surface of the holder is configured to hold a line laser.

An illuminable ball device including at least one or more LEDs for illuminating said device, an electrical circuitry for controlling said one or more LEDs, a battery for providing power to said electrical circuitry and energize said one or more LEDs, a first housing including a casing, a second housing, a cavity part within said casing, wherein said cavity part is configured to received said second housing, a cap portion, in which said cap portion is configured to secure over said second housing, and wherein said cap portion and said second housing is attached to said casing part by a low reverse torque closure.

A softball pitching machine in accordance with the present disclosure is configured to lob a softball along an arcuate path with forward spin to mimic the motion of an underhand, slow pitched softball from a human pitcher. The softball pitching machine includes a throwing arm having a curved hand configured to move along a predetermined arcuate path to a preset stopping point that imparts the arcing path and the forward spin on the softball.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

An exercise rating and improvement system comprising: a feature amount extraction unit for extracting, from information obtained from a subject, a feature amount about exercise efficiency; an rating unit for rating exercise efficiency of the subject by comparing the extracted feature amount and a feature amount to be compared; and an improvement information providing unit for providing, on the basis of the rating result, information such that the feature amount of the subject approaches the feature amount to be compared.

The present disclosure is directed to foldable roping dummy assemblies and systems. In a first illustrative embodiment, a central support portion may have right and left leg assemblies and an upper body chamber generally formed as tube. A body cylinder slidable in the upper body chamber may be connected to a head assembly via a linkage at a front end. In a folded position, the head assembly resides between the leg assemblies. As the head assembly is lifted into position, the body cylinder slides rearward and the linkage rotates the head assembly into position at the front of the upper body chamber. In a second illustrative embodiment, the central support portion may be formed as a set of stairs which includes a central cavity open on at least one side, such that in a folded position, the head assembly resides in the central cavity.
