A funnel with the ability to receive and secure one or more inverted source containers for transferring fluids to a receiving container, without requiring the assistance of a user. A first partial thresholding unit creates an output binary image by extracting a character area from the input image, which corresponds to a character area identified from the created edge image, and performs a thresholding operation on the extracted character area. Each signal transmission line penetrates through a section of the substrate near one end thereof. In both embodiments the adhesive layer remains on the bottom surface of the patch when the label or card intermediate is removed from the form. Methods of use for such vectors are also included herein. The stacked semiconductor device includes a first insulating interlayer having an opening that partially exposes a substrate, wherein the substrate includes single crystalline silicon, and a first seed pattern that fills the opening, wherein the first seed pattern has an upper portion disposed over the opening, and the upper portion is tapered away from the substrate.
