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.

Golf balls are disclosed that include a centerline axis; an aperture located within the centerline axis; and a kinetic projectile located within the aperture. The kinetic projectile may consist of a hammer actuated .22 caliber single shot load or .27 caliber single shot load. The aperture may, optionally, further include an amount of black powder disposed therein. The golf balls are configured to launch farther and/or produce a striking sound greater than conventional golf balls—when the balls are struck on the backside of the kinetic projectile disposed within the aperture of the golf balls.

A ball chair may comprise a chair frame, a ball body and an adjusting unit. The chair frame has a connecting base and a legs base, and a supporting column formed therebetween is configured to achieve a telescopic action thereby adjusting a height of the ball chair. The connecting base is formed in a concave shape to form a housing space therein, and an annular frame is formed at an upper end of the connecting base. The ball body is configured to be coupled on the connecting base of the chair frame, and the annular frame is configured to couple with an outer periphery of the ball body thereby limiting a position thereof. As a result, the ball chair is suitable for different statures of users and enables the users to sit thereon for training or rehabilitation.

A pressing toy made of silicone is disclosed, including a first hollow housing and a second hollow housing that can be assembled into a housing body. The inner cavity of the first hollow housing and the inner cavity of the second hollow housing are assembled to form an inflatable chamber. The outer peripheral wall of the housing body is provided with a number of elastic protrusions that protrude outward. The elastic protrusions are of a hollow structure, and the inner cavity of each of the elastic protruding protrusions is communicated with the inflatable chamber. By pressing the housing body, some of the elastic protrusions are raised, or some elastic protrusions can be pressed so that some other elastic protrusions are raised, thereby creating a visual feedback of the deformation caused by the pressing action.

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.

A sports and performance media positional detection system, comprising: at least two elements, with at least one element involved in the sporting activity; a power source; and machine-to-machine communication, which are collectively arranged such that if any two or more elements interact, their electromagnetic properties can be detected thus allowing the position of the interacting elements to be communicated to a decision maker. The system can be applied to at least one stationary element, which can be the playing surface, lines defining the boundaries, or a set of goalposts; and at least one moving element, which could be a ball, footwear, or the participants themselves. The system can also be applied to performance media capture.
