Abstract: An apparatus and method is provided for removing undesired coiling or twisting that has developed in a power cable attached to a robotic swimming pool cleaner during the cleaner's pre-programmed or random movement over the bottom and/or side walls of the pool. A rotatable grip assembly is permanently or removably affixed to the power cable adjacent one or both ends of the power cable that can be disconnected from the power supply or the pool cleaner. The rotatable grip assembly includes one or more bearings, at least a portion of which bearings is fixed with respect to the power cable, and a gripping member that is in contact with the one or more bearings.

Abstract: A remotely controllable, transforming, water squirting toy vehicle includes a structure in the form of a lever arm mounted for pivotal movement with respect to a remainder of the vehicle from a first position in which a surface of the arm is hidden within the vehicle to a second, elevated position in which the hidden surface of the arm is exposed. The hidden surface of the arm bears the likeness of a snake or other creature and includes a nozzle fluidly coupled to a pump and reservoir within the remainder of the vehicle. A control system in the vehicle receives and processes steering and propulsion control signals as well as an arm raising/water pumping control signal. A single actuator controls the movement of the lever arm which is spring loaded, by releasing the lever arm from a latched position and powers the pump driving liquid from the reservoir to the nozzle.

Abstract: An interrupted inverted jump loop for an electric toy vehicle track, including a first generally arcuate slotted track for launching an electric toy vehicle into the air to carry out an upside-down free-flying jump and a second generally arcuate slotted track spaced from and suitably aligned with the first slotted track for catching the electric toy vehicle after it is traversed through the air. A portion of the first slotted track is electrically powerless for allowing the electric toy vehicle to freely launch towards the second slotted track.
