    Abstract: An electrokinetic pump for pumping a liquid includes a pumping body having a plurality of narrow, short and straight pore apertures for channeling the liquid through the body. A pair of electrodes for applying a voltage differential are formed on opposing surfaces of the pumping body at opposite ends of the pore apertures. The pumping body is formed on a support structure to maintain a mechanical integrity of the pumping body. The pump can be fabricated using conventional semiconductor processing steps. The pores are preferably formed using plasma etching. The structure is oxidized to insulate the structure and also narrow the pores. A support structure is formed by etching a substrate and removing an interface oxide layer. Electrodes are formed to apply a voltage potential across the pumping body. Another method of fabricating an electrokinetic pump includes providing etch stop alignment marks so that the etch step self-terminates.

    Abstract: This disclosure relates generally to an online film festival allows a first user and a second user to submit a first film and a second film, respectively. The films are submitted via a digital interface and a viewer can view the submitted films through those means as well. The viewer can vote, comment on, and/or contribute funds to film of his or her choice, with the funds being contributed after presentation of the film. A vote tallying portion of the digital interface tracks and counts a number of votes associated with the film. The winning film can be determined by the number of votes or a jury.
