Description:
CROSS-REFERENCE TO RELATED APPLICATIONS

This application is related to co-pending U.S. patent application Ser. No. 60/772,180 filed on May 7, 2007, entitled MULTILAYERED MICROCAVITIES AND ACTUATORS INCORPORATING SAME, which is hereby incorporated by reference as if set forth in full in this application.

This application is related to U.S. Pat. No. 7,021,217, issued Apr. 4, 2006, entitled VERSATILE CAVITY ACTUATOR AND SYSTEMS INCORPORATING SAME, which is hereby incorporated by reference as if set forth in full in this application.

BACKGROUND OF THE INVENTION

1. Field of Invention

This invention relates to actuators. Specifically, the present invention relates to devices and components thereof for selectively initiating an action and further relates to methods for making such devices and components.

2. Description of the Related Art

Initiators are employed in various demanding applications, including airbag activation, . . . . More
Abstract:
An actuator assembly that includes, in one example embodiment, a substrate with a bridge coupled between a first electrode and a second electrode on the substrate. A lithographically disposed flyer is positioned in proximity to the bridge. In a more specific embodiment, the actuator assembly further includes a lithographically disposed barrel that partially surrounds the flyer. A fireset is coupled to pins that extend through the substrate to the first electrode and the second electrode. The flyer further includes a three-dimensional surface adapted to flatten during flight. The flyer may be concave, convex, or may star shaped, may have perforations therein, or may exhibit another shape or other features.
Claims:
What is claimed is:

1. An actuator assembly comprising: a substrate; a first electrode disposed on the substrate; a second electrode disposed on the substrate; a bridge coupled between the first electrode and the second electrode; a lithographically disposed flyer in proximity to the bridge; first means for activating the bridge via application of a signal to the first electrode and the second electrode; a lithographically disposed barrel positioned in proximity to the lithographically disposed flyer, wherein the barrel includes tabs extending therefrom; and one or more grooves in the substrate to which the tabs are coupled.

2. An actuator assembly comprising: a substrate; a first electrode disposed on the substrate; a second electrode disposed on the substrate; a bridge coupled between the first electrode and the second electrode; and a lithographically disposed flyer in proximity to the bridge, wherein the flyer includes one or more holes therein.
