Abstract: There is provided in one embodiment an imaging and sensing assembly. The imaging and sensing assembly has a disc shaped aerodynamic member configured to spin and self-position in flight, a plurality of pulsed thrusters positioned on the member, and a plurality of imaging and sensing devices positioned along a perimeter of the member. The imaging and sensing assembly further has one or more antenna devices positioned on the member and in communication with a first processor device on the member. The first processor device receives data obtained by the plurality of imaging and sensing devices and wirelessly transmits the data to a second processor device not positioned on the member. The imaging and sensing assembly further has a power supply powering the imaging and sensing assembly.

Abstract: A solar energy harvesting apparatus is disclosed. An illustrative embodiment of the apparatus includes a generally elongated, rectangular body having a bottom portion and sidewalls extending from the bottom portion; at least one trough provided in the bottom portion and having a trough base and trough peaks; at least one mirror strip provided along at least one peak of the at least one trough; and a linear solar cell provided along the trough base of the at least one trough.

Abstract: An airfoil launching system having a rod with a structure attached to a first end of the rod. A pusher holds a ring airfoil and has a sufficient coefficient of friction that the ring airfoil will generally rotate with the pusher and is rotatably and slidably mounted on the rod. Propulsive force is provided by resilient bands connected to the structure outward from the rod and to the pusher outward from the central aperture of the pusher. A grip attached to the pusher is utilized to draw the pusher toward the second end of the rod, thereby stretching and energizing the resilient bands, and also to rotate the pusher and, consequently, the airfoil.

Propulsive force is provided by resilient bands connected to the structure outward from the rod and to the pusher outward from the central aperture of the pusher. A string guide is rotatably attached to the rod and has apertures through which generally non-resilient cords, the first ends of which are attached to the pusher outward from the central aperture, pass. The second ends of the generally non-resilient cords are connected to each other, preferably with a pliable grip.

Abstract: A propulsion-assisted projectile has a body, a cowl forming a combustion section and a nozzle section. The body has a fuel reservoir within a central portion of the body, and a fuel activation system located along the central axis of the body and having a portion of the fuel activation system within the fuel reservoir. The fuel activation system has a fuel release piston with a forward sealing member where the fuel release piston is adapted to be moved when the forward sealing member is impacted with an air flow, and an air-flow channel adapted to conduct ambient air during flight to the fuel release piston.

Abstract: Toys and methods for safely and reproducibly launching ring airfoils in a flying orientation. The toys generally comprise a member, a ring airfoil support mounted on the member, and a propelling element configured to move the ring airfoil support along the member from a first to a second position. Contact between the ring airfoil and the ring airfoil support causes the ring airfoil to move with the ring airfoil support as the ring airfoil support moves; this contact is overcome as the ring airfoil support decelerates at the second position, causing the ring airfoil to be launched with forward or both forward and spinning motion. The toys further may comprise a housing to protect the toy and user, a return element to place the toy in an engaged, launch-ready configuration, and a trigger to hold the toy in the engaged configuration until launching.
