    Abstract: A method is provided for using a single-pixel imager in order to spatially reconstruct an image of a scene. The method can comprise the following: configuring a light filtering device including an array of imaging elements to a spatially varying optical filtering process of incoming light according to a series of spatial patterns corresponding to sampling functions. The light filtering device can be a transmissive filter including a first membrane, a second membrane, and a variable gap therebetween. The method further comprises tuning a controller for manipulating a variable dimension of the gap; and, measuring, using a photodetector of the single-pixel imager, a magnitude of an intensity of the filtered light across pixel locations in the series of spatial patterns. The magnitude of the intensity can be equivalent to an integral value of the scene across the pixel locations.

    Abstract: A nanoprinthead including an array of nanotip cantilevers, where each nanotip cantilever includes a nanotip at an end of a cantilever, and a method for forming the nanoprinthead. Each nanotip may be individually addressable through use of an array of piezoelectric actuators. Embodiments for forming a nanoprinthead including an array of nanotip cantilevers can include an etching process from a material such as a silicon wafer, or the formation of a metal or dielectric nanotip cantilever over a substrate. The nanoprinthead may operate to provide uses for technologies such as dip-pen nanolithography, nanomachining, and nanoscratching, among others.

    Abstract: A structure and method for a post plate of a die set that can be used to emboss a plurality of contact pads of a flexible printed circuit during the formation of a printer printhead. In one embodiment, a plurality of post plate posts can be formed, where each post plate post has a flat upper surface, generally straight sides, and a sharp corner where the flat upper surface and the generally straight sides intersect. Each post can be polished using, for example, a pad and an abrasive polishing compound or an electrochemical polishing process, to round the sharp corners to form a post having a rounded contour. In another embodiment, a plurality of post plate posts each having a rounded contour can be formed using a molding process.
