A technique for enabling a firewall device to allow encrypted data to securely pass between networks, and at the same time allow the firewall to selectively monitor the encrypted traffic that is allowed to pass is disclosed. The HTTP client causes the computer executable to process files of the first type. Thereby, fault correction activities can be optimized. In addition, the system may incorporate a solid-state feed relay carried by the aircraft remote from the rotor and conductively coupled between the power supply and the control relay for selectively controlling the flow of electrical power to the control relay. To this end, at least one constituent of the adhesive is partly crosslinked and the partly crosslinked constituent is the product of partial crosslinking of at least one monomer containing double bonds, the monomer containing double bonds being a partial ester prepared by the reaction of an epoxy resin with an unsaturated carboxylic acid. Accordingly, an unnecessary time and cost causable by temperature compensation can be reduced, and an automatic temperature compensation and a precise temperature sensing operation can be obtained.
