Abstract: An invention to protect the surface of dining table food containers that are commonly used among patrons of eating establishments, dining halls and cafeterias from the collecting and retransmitting of non-sanitized hand-borne or air-borne germs and pathogens introduced through contact with commonly used dining table food containers. The invention involves the new use of specially formed paper as an external container for various dining table food containers. The specially formed paper is configured in a tubular shape to encase dining table food containers of various dimension and thereby protect the enclosed surface of a properly sanitized dining table food container from germ accumulation. The specially formed paper tube is further treated with commercially available chemical agents, applied to its outer surface, in order to inhibit the collection, accumulation and retransmission of non-sanitized hand-borne or air-borne germs introduced through repeated non-sanitized hand or atmospheric contact.

Abstract: Capacitive identification systems and methods are described. The system may include a capacitive detector configured to identify objects having capacitive identifiers. A capacitive identifier may be a patterned dielectric ink that, when placed in an electromagnetic field generated by the capacitive detector, detectably alters the capacitance of neighboring sensors in the detector. The capacitive detector may be disposed within an opaque housing structure of a device and configured to detect the capacitive identifier through the opaque housing structure. The capacitive detector may include a capacitive sensing array and processing circuitry formed on a common printed circuit. The capacitive detector may be formed in an infusion pump system. The capacitive identifier may be disposed on a pump cassette for the infusion pump system.
