Abstract: Diffusion bonding a stack of aluminum thin films is particularly challenging due to a stable aluminum oxide coating that rapidly forms on the aluminum thin films when they are exposed to atmosphere and the relatively low meting temperature of aluminum. By plating the individual aluminum thin films with a metal that does not rapidly form a stable oxide coating, the individual aluminum thin films may be readily diffusion bonded together using heat and pressure. The resulting diffusion bonded structure can be an alloy of choice through the use of a carefully selected base and plating metals. The aluminum thin films may also be etched with distinct patterns that form a microfluidic fluid flow path through the stack of aluminum thin films when diffusion bonded together.

Abstract: Methods and systems are disclosed for presenting targeted public content and multimedia coverage content related to public decisions to users that may find them relevant to their lives. In some embodiments, a system according to the present disclosure may analyze public content and multimedia coverage content to identify associations to public decisions and may determine the relevancy of those public decisions to certain users. Public decisions that are relevant to certain users are presented to those users via a display of a computer device. In some embodiments, options are provided that allow users to vote on positions associated with the public decisions, contact key decision makers and influences, and to connect with other users that hold the same or similar positions.

Abstract: Micro-channel-cooled UV curing systems and components thereof are provided. According to one embodiment, a lamp head module includes an optical macro-reflector, an array of LEDs and a micro-channel cooler assembly. The array is positioned within the reflector and has a high fill factor and a high aspect ratio. The array provides a high irradiance output beam pattern having a peak irradiance of greater than 25 W/cm2 at a work piece surface at least 1 mm away from an outer surface of a window of the reflector. The micro-channel cooler assembly maintains a substantially isothermal state among p-n junctions of the LEDs at less than or equal to 80° Celsius. The micro-channel cooler assembly also provides a common anode substrate for the array. A thermally efficient electrical connection is formed between the array and the common anode substrate by mounting the array to the micro-channel cooler assembly.

Abstract: An item of content is protected by monitoring a plurality of file sharing networks to identify at least a first file sharing network having the item of content. At least first and second reference files associated with the item of content are created, where the first and second reference files each have a different format. A plurality of decoy files are created, including a first set of decoy files created from the first reference file, and a second set of decoy files created from the second reference file, where each of the decoy files including a defect. The decoy files are disseminated to the first file sharing network.
