Abstract: A novelty device, which may be portable and connected to an article of clothing, includes an antenna that receives an operating signal carrying an activation command. A receiver within the novelty device is coupled to the antenna and demodulates the modulated operating signal to produce an operating signal, which in turn, is decoded by a decoder to detect the presence or absence of the activation command. An operator-controlled signal source sends an activation command to a transmitting unit, which in turn, modulates the activation command to provide a modulated operating signal to one or more novelty devices via an over-the-air channel. When the decoder detects the presence of the activation command, the decoder operates a switch to activate an indicator, which may produce lights, emit sounds, or perform some mechanical action or any other visual or audio effect.

Abstract: A high temperature film wrapping is used to wrap thermoplastic materials before they are molded. The thermoplastic material can then be molded by applying heat and pressure and the resulting thermoplastic material will contain reduced cracks and voids compared with thermoplastic materials molded without the wrapping.
