A communication system 100 includes a content repository 274 storing a plurality of content files associated with the content distribution system. Alternatively, the method includes the steps of: providing an electrically conductive tissue engaging plate and a jaw support; covering one side of the electrically conductive tissue engaging plate with an electrically insulative, thermally non-degrading coating; and securing the side of the electrically conductive tissue engaging plate onto the jaw support with an adhesive. Thus, the gate line and the data line may be tested using the contact portions as electrical terminals during the manufacturing process of the display apparatus. The feed pretreatment of this invention may include the steps of distillation, extraction, andor adsorption by solid adsorbent, which may be regenerated in accordance with further embodiments of this invention. The sensor is associated with a controller and sump or bilge pump.
