Abstract: The process of casting a ballot from a remote location over electronic means faces a lot of technological challenges. One key challenge is the fact a purely electronic process leaves no physical or paper audit trail behind for voters to verify their ballots have been recorded properly, and for use in case of a recount. The present invention demonstrates a means to solve this problem by implementing a remote voter-verifiable paper audit trail (R-VVPAT) device.

Abstract: A method for the co-processing of bare die removal from a semiconductor wafer for the improved throughput of the extraction of die from a wafer for subsequent placement onto a substrate. The apparatus includes a pick head containing a nozzle having a suction port within that secures the bare die as it is removed from the wafer. The intermediate holding station has a plurality of nozzles, each having a vacuum port to secure and buffer a multitude of flipped die that are transferred from the pick nozzle. Vacuum flow valves enable the release and transfer of the bare die. Having a multiple of nozzles provides a buffer for the die as they are subsequently transitioned from the pick nozzle, queued within the intermediate transfer station and loaded in tandem onto a die shuttle.
