Abstract: Interactive entertainment devices including a toy magic wand with integrated electronics for, among other things, detecting wand motion and responding accordingly, such as illuminating one or more LEDs, displaying images on one or more LCD displays, playing sound effects or character speech, emitting infrared (IR) signals via one or more IR emitters, or some combination thereof. An exemplary device may include a “fairy house” or “wizard tower” playset with integrated electronics for receiving one or more received IR signals and responding or reacting accordingly. For example, depending on the nature of the received IR signals, the electronics may illuminate one or more LEDs, display images on one or more LCD displays, play sound effects or character speech, emit IR signals via one or more IR emitters, or some combination thereof.

Abstract: A device for spraying an inner surface of a wall of an enclosure with a fluid is disclosed. The device includes a reservoir for the fluid, a nozzle assembly through which the fluid can be sprayed on the inner surface of the wall of the enclosure, a fluid conduit in fluid communication with the reservoir and the nozzle, a pump for delivering fluid from the reservoir through the fluid conduit and to the nozzle when the pump assembly is activated, and a controller in electrical communication with the pump wherein the controller executes a stored program to activate and deactivate the pump. The nozzle assembly includes a nozzle which directs the fluid in a fluid path, and the nozzle assembly further includes a deflection shield that is dimensioned to contact and redirect fluid in the fluid path, and the nozzle assembly further includes mounting structure for attaching the nozzle near the inner surface of the wall of the enclosure. The flow off of the deflector shield is laminar.

Abstract: A mechanized, movable toy with the ability to interact with and explore its environment, while performing actions and creating noises at specific intervals. The toy has at least two receivers and a control unit capable of detecting wireless signals from a source and capable of reacting to move towards the source of the wireless signals. Once the toy enters within an area of the source, the toy performs a new action. The source may be a stationary device, handheld device, movable device, or another mobile toy. The toy may contain switches thereupon to switch the toy on or off. The receivers may be arranged in and around the toy to detect the wireless signals from one side of the toy or another.

Abstract: A valve having a membrane for controlling flow through the valve, the membrane having open and closed positions. An element urges the membrane to the closed position, and a vacuum pressure at one end of the valve may overcome the urging of the element, thereby moving the membrane to the open position. An actuator is provided for easing or initiating the movement of the membrane. In some embodiments, the valve may take the form of a valve assembly for use in a variety of applications, for example, a valve assembly for relieving a vacuum pressure wherein the assembly includes intake and exhaust ends, a membrane for controlling flow through the assembly, a spring providing a closing bias to the membrane that the vacuum pressure may overcome to move the membrane, and an actuator for initiating the movement of the membrane.

Abstract: A track set includes track sections having parallel first and second rail edges on which a ball travels. Each track section includes a first upstanding sidewall projecting from the first rail edge having a first guide rail positioned a sufficient distance radially outward of the first rail edge. Each track section further includes a second upstanding sidewall projecting from the second rail edge having a second guide rail positioned a sufficient distance radially outward of the second rail edge. A connection member includes a resilient retaining portion configured to be inserted and retained between two spaced-apart pillar supports on at least one other track section to attach thereto. The track sections accommodate a derailed ball using a guide rail positioned a sufficient distance from an adjacent rail edge, to support the derailed ball via the guide rail and one rail edge when the ball rolls off the first and second rail edges.

Abstract: An entertainment device is configured to receive a limited range wireless signal from at least one other entertainment device when adjacently arranged in close physical proximity to at least one other entertainment device, and to responsively operate in a first mode or a second mode based on whether the other entertainment device is adjacent a first side or second side. In the first mode, the entertainment device initiates one or more wireless activation signals to control an audio/visual element of another entertainment device. In the second mode, the entertainment device receives wireless activation signals from another entertainment device to control activation of an audio/visual element of the receiving entertainment device. Each device is interchangeable between operation in the first mode of controlling at least one other entertainment device and the second mode of being controlled by another entertainment device based on position of one entertainment device relative to the other.
