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: This invention relates to a method and apparatus for collecting or collimating light for detection. More particularly, the invention is directed to a technique for detecting the edge of an object using an apparatus having a plurality barriers or shield structures that are advantageously aligned with an optical sensor array to collect or spatially filter generated light for improved detection of the light. The invention also relates to methods of forming the structure. Application of the invention is found in the field of detecting edges of objects such as sheets of paper that are fed through imaging devices along a paper path.

Abstract: A method and apparatus for improved cutting of an object is provided. The object can take the form of many different structures including thin formations that require cutting precision, support, and dimensional control. In accordance with one example embodiment of the present invention, the method of cutting a member uses a laser and begins with the step of providing a template removably adhered to the member. The laser then projects through the template, without intersecting with the template, to cut the member and manufacture the desired formation. The laser does not intersect with, and therefore does not cut, the template structure and cause excess laser cutting dust.

Abstract: An apparatus for processing a substrate on two sides. A substrate has a first edge as a leading edge in a process direction and a first side in a face-up orientation. In one embodiment, the apparatus comprises an input pathway for receiving the substrate from a substrate processing station, a station for processing the face-up side of the substrate, a reversion pathway for reverting the substrate and returning the reverted substrate to the input pathway. After reversion, a second side of the substrate is in the face up orientation and the first edge is the leading edge. A merge point merges the reverted substrate into the input pathway for processing the face-up side of the substrate in the print station.
