  • Patent number: 12153322
    Abstract: A light attenuator that provides transparent light states and absorbing dark states for use in selectively controlling light, especially for smart glass applications. The light attenuator includes abutting areas of attenuation and transparency that form a repeat pattern or a quasi-repeat pattern. The attenuating areas are visible when the light attenuator is in the light state, but the repeat pattern is sufficiently large that a viewer looks through the attenuator and sees no haze.

  • Patent number: 9975171
    Abstract: Disclosed are systems and methods for mechanically reducing an amount of the skull material in a finished, molded part formed from amorphous alloy using an injection molding system. Skull material of molten amorphous alloy can be captured in a trap before molding such material. A cavity can be provided in the injection molding system to trap the skull material. For example, the cavity can be provided in the mold, the tip of the plunger rod, or in the transfer sleeve. Alternatively, mixing of molten amorphous alloy can be induced so that skull material is reduced before molding. A plunger and/or its tip can be used to induce mixing (e.g., systematic movement of plunger rod, or a shape of its tip). By minimizing the amount of skull material in the finished, molded part, the quality of the part is increased.

  • Patent number: 9955533
    Abstract: An induction shield is configured to substantially reduce emissions emitted from an induction heat source (e.g., coil) during use. The shield is positioned adjacent to a vessel (e.g., in an injection system) having a melting portion configured to receive meltable material to be melted therein and an induction heat source positioned adjacent the vessel configured to melt the meltable material received in the melting portion of the vessel. The shield may include a tube configuration configured to flow liquid therein to absorb heat emitted from the heat source. The tube configuration can comprise a single tube or multiple tubes. The shield can be positioned adjacent the induction source in a helical manner, for example, or at ends of the vessel. The shield can be used during melting of amorphous alloy and for forming a part.
