The systems and methods of the present invention provide for conductive emissions communication without requiring dedicated communications wires. The cover has a color or design which differs from that of the crankbait body, so that installation of the cover effectively changes the appearance of the crankbait body. The battery assembly is composed by electrically connecting a plurality of secondary batteries in series or in parallel. A time period after which it is predicted that the measured parameter will have left its current sub-range is calculated based on a current value of the measured parameter and the calculated trend information. The invention further relates to the treatment of diseases andor conditions through binding of the nuclear receptor by the compounds and the production of medicaments using the compounds.
