An electric latch retraction device comprising a housing for receiving a plurality of internal components of the electric latch retraction device. The composite is manufactured by first diffusing an oxidant such as iodine into the polymer, and then diffusing pyrrole or a pyrrole derivative vapor into the impregnated polymer, resulting in an in situ chemical oxidative polymerization of pyrrole at the oxidant site. The container assembly may be received within a receiving chamber for causing the coupling. The invention further relates to the porous materials which can be obtained in this way and the use of the porous materials as thermal insulation material and in vacuum insulation panels. The present invention reduces the time for outputting the control signals and greatly reduces the power consumption of the optical drive thereby. The device is driven by setting an arbitrary horizontal extraction period is set in a horizontal sync period, and making a selection between a first horizontal transfer signal and second horizontal transfer signal which is to be transferred at a higher rate than the first horizontal transfer signal.
