Abstract: Resonant sensors for environmental health risk detection are disclosed. An adhesive may include at least one meso-scale or micro-scale resonator embedded within a material that comprises at least a portion of the adhesive. The at least one meso-scale or micro-scale resonator may be formed from a composite material. Additionally, the at least one meso-scale or micro-scale resonator may include a plurality of first carbon particles configured to uniquely resonate in response to an electromagnetic ping based at least in part on a concentration level of the first carbon particles within the at least one meso-scale or micro-scale resonator.

Abstract: A toy having an internal gyroscopic element is disclosed, including ways of using the toy. A toy having a gyroscopic element is intended to provide an entertaining play experience by providing resistance to movement of the toy when it is used in, for example, a role playing situation. Movement of the gyroscopic element may manually be initiated by a person playing with the toy, and the duration and degree of movement of the gyroscopic element may be limited by natural forces.

Abstract: A flying toy may comprise an elongate body extending along a body axis from a forward end to a rearward end. The flying toy may comprise a wing assembly, comprising a wing adapted to move relative to the body between an extended position in which at least a portion of the wing extends away from the body and a retracted position in which the wing portion is closer to the body. The flying toy may comprise an actuator movable along the body between a forward position and a rearward position. One of the wing assembly and the actuator may comprise a contact element, and the other of the wing assembly and the actuator may comprise an elongate contact surface extending obliquely relative to the body axis. The contact element may move along the contact surface as the actuator moves between the rearward position and the forward position, thereby moving the wing between the retracted position and the extended position.
