A throwing object comprises an air cushion section joined to a rim. The rim comprises an inner surface and a sequence of curved contour sections where the inner surface of the rim is at one end joined to an inner surface of the air cushion section and at a second end is joined to an outer surface of the air cushion section via the contour sections. The contour sections interconnect the inner surface with the outer surface via a first extreme radius placed at a maximum horizontal distance from the inner surface, the inner surface has a first curvature and a last contour section in the sequence together with at least a part of the outer surface has a second, different curvature.

A propeller food plate assembly has a plate component and a propeller component that includes a plurality of propellers that subdivide the plate into a plurality of compartments for holding food during a dining activity. During a different recreational activity, the components rotate when the assembly is thrown and spun in the air. During flight, the components initially engage each other in a torque-transmitting relationship, and subsequently move apart. The propellers have contoured, aerodynamic surfaces configured to enhance an aerodynamic flight characteristic of the assembly, One or more light sources may be mounted on the assembly to emit light.

A swinging bob toy having a first outer bob attached to a first outer looped tethering means, a second outer bob attached to a second outer looped tethering means, and a central bob attached to a central looped tethering means, the first outer looped tethering means being attached at an outer end of a first segment of the central looped tethering means, and the second outer looped tethering means being attached at an outer end of a second segment of the central looped tethering means. The outer looped tethering means are attached to the central looped tethering means by means of half hitches, the outer looped tethering means are attached via apertures in the bobs by means of half hitches, thereby allowing the toy to be rapidly disassembled and reassembled, possibly with the incorporation of components from additional toys, in other configurations. The central looped tethering means is a non-hollow string while the outer looped tethering means are coreless tethering means which generally take a flattened state.

A frisbee balanced to spin about a central axis has a central portion with a top surface and an opposing bottom surface. The central portion terminates peripherally with a circular rim having a sinusoidal curvature. The central portion conforms to the sinusoidal curvature of the rim forming radial variations of peaks and valleys. Plural sinusoidal cycles of radially directed, convex peaks impart thrust enabling it to float in a chosen direction when thrown and to rotate about its central axis developing lift due to air passing over the generally domed top surface.

Embodiments include devices and methods for capturing images of a game by an unmanned autonomous vehicle (UAV). A processor of the UAV may determine game play rules of the game. The processor may predict a game action based on the determined game play rules. The processor may determine a position from which to capture an image of the game based on the predicted game action, and may move the UAV to the determined position to enable the UAV to capture of an image of the game from the determined position.

A ball toy having a solid, resiliently flexible body is disclosed. The body is penetrated by a bore, wherein bearing means are mounted, defining a rotational axis of the body therein. The bore has a bore closure at each end, mechanical connection means connecting each closure to the bearing means. The body is able to spin on said axis relative to the closures, when the closures are held in a pinching manner by a user. The body is made of a thermoplastic rubber of selected hardness properties, giving it excellent bouncing performance, with unpredictability of bouncing direction resulting from the spinning of the body.
