Black & White Patent Drawings

I need a set of clean, black-and-white line drawings suitable for a patent filing. The figures must follow USPTO standards: uniform line weight, no shading or color, clear reference numerals, and margins that respect the official template.

I will provide rough sketches and a short description of each figure; your task is to translate them into crisp vector artwork (AI or SVG) plus printable PDF sheets at 300 dpi. If you work in Illustrator, CorelDRAW, or similar software that exports layered vectors, that’s perfect—just keep the lines editable and the text in a standard sans-serif font.

Please include examples of previous patent or technical drawings you’ve produced when you reply. Final delivery will be the source files and ready-to-file PDFs, with one minor revision round included to catch any examiner feedback or numbering tweaks.
