Abstract: A device for harvesting and storing triboelectric charge generated on an exterior surface of a moving vehicle is provided. It is characterised by comprising; a supercapacitor comprised of nano-carbon-containing electrodes; an ionic liquid electrolyte and at least one ion-permeable porous membrane; at least one first element exposed to aerodynamically-induced frictional forces acting thereon and on which the charge is caused to build up and connected to at least one of the electrodes of one polarity; at least one second element having a lower electrostatic potential than the charge-collecting element and connected to at least one of the electrodes of the other polarity; a voltage modification or impedance conversion circuit arranged between the first and/or second elements and the supercapacitor; means to connect the device to an operative component requiring electrical power and a controller for managing the performance of the device and switching between energy-harvesting and energy-utilisation modes.

Abstract: A toy doll has a mouth opening adapted to receive a simulated nursing bottle from which water is fed to the interior of the doll, some of such water producing a wetting action. The doll is also adapted to produce a burping sound when its back is patted, and simultaneously to spit up through the mouth opening some of the water previously fed from the bottle. The burping sound is produced by a bellows in the body portion of the doll which is successively compressed upon patting the back of the doll and which progressively feeds air into another bellows located in the head of the doll until the head bellows reaches an expanded position. An actuating member then automatically releases the air from the expanded head bellows, which air flows in a sudden controlled flow through a sound producing device. Some of this released air also causes liquid to be emitted from the mouth opening to produce the spitting-up effect.

Abstract: A miniature toy vehicle launcher having an inclined platform adapted to support a toy vehicle in a launching position. A stop is provided which is movable from a hold position to hold the toy vehicle on the platform against movement and to a release position for release thereof. A finger is movably coupled with the stop to move it to the hold position, and the stop is spring biased by means of a first spring towards the release position to move the stop to the release position. A locking element retains the stop in the first position against the tension of the first spring, and a slide is spring biased by means of a second spring for movement to disable the locking element to cause the stop to move to its release position.
