Abstract: A capsule dimensioned and shaped to move with the body of a living subject for identifying tissues related to at least one lesion along a gastrointestinal tract of the living subject. In one embodiment, the capsule has locating means for locating tissues related to at least one lesion along the gastrointestinal tract, and marking means for marking the tissues related to at least one lesion along the gastrointestinal tract with an identification material stored within the capsule, wherein the marking means is automatically triggered when a predetermined condition is satisfied.

Abstract: Methods, systems and apparatus for modeling capacitance for a structure comprising a pair of long conductors surrounded by a dielectric material and supported by a substrate. In particular, the structure may be on-chip coplanar transmission lines over a conductive substrate operated at very high frequencies, such that the substrate behaves as a perfect dielectric. It is assumed that the surrounding dielectric material is a first dielectric with a first permittivity (e1) and the substrate is a second dielectric with a second permittivity (e2). A method models the capacitance (C1) for values of the first and second permittivity (e1, e2) based on known capacitance (C2) computed for a basis structure with the same first permittivity (e1) and a different second permittivity (e2). Extrapolation or interpolation formulae are suggested to model the sought capacitance (C1) through one or more known capacitances (C2).
