    Abstract: This invention relates to a method and apparatus for high-speed fluid flow control. More particularly, the invention is directed to a valve formed, at least in part, of an actuating material, such as piezoelectric or anti-ferro-electric material. The valve is used for controlling fluid flow (including air flow) in a variety of devices including imaging devices (e.g. printers, copiers, etc.) for which air flow is used to handle paper. In one embodiment, the subject valve takes advantage of the phenomenon of buckling, resultant bistability and other structural mechanics to efficiently, and in a high-speed manner, open and close to regulate fluid flow. In another embodiment, the valve includes implementation of the actuating material to bend an s-shaped blocking element within the valve. The valve is also advantageously implemented in matrices and formed using batch fabrication techniques.

    Abstract: Efficient methods for lithographically fabricating spring structures onto a substrate containing contact pads or metal vias by forming both the spring metal and release material layers using a single mask. Specifically, a pad of release material is self-aligned to the spring metal finger using a photoresist mask or a plated metal pattern, or using lift-off processing techniques. A release mask is then used to release the spring metal finger while retaining a portion of the release material that secures the anchor portion of the spring metal finger to the substrate. When the release material is electrically conductive (e.g., titanium), this release material portion is positioned directly over the contact pad or metal via, and acts as a conduit to the spring metal finger in the completed spring structure. When the release material is non-conductive, a metal strap is formed to connect the spring metal finger to the contact pad/via.
