The invention is directed to Compounds of Formula I: and pharmaceutically acceptable salts or solvates thereof, as well as methods of treating using the compounds, methods for screening for inhibitor compounds and methods for identifying treatment regimens. The coupler has a transmission line electromagnetically coupled to a coupled line, and the coupled line has an isolated node and a coupled node. The first advertisement packet includes a payload encrypted based on a predetermined key. The air filter sensor kit also includes a cutting tool guide that is adjustable to conform to various configurations of air filter grills. In one embodiment, first and second mechanical sense components are electrically conductive and operate to sense a change in a capacitance between the mechanical sense components in response to a mechanical indicator from a magnetic-to-mechanical converter.
