In a system for viewing accumulated contents by using a cellular phone, if an error prevents the content to be viewed, a simple operation is performed to view the rest at home. The method may include introducing a gas to a reaction chamber containing the substrate; illuminating the ion implanted photoresist with radiation from a laser in the presence of the gas; and scanning the radiation across the surface in the presence of the gas to photoreactively remove the ion implanted photoresist from the surface. When the user selects relevant TV information about the desired program, the PDA sends to a personal computer the information for presetting the TV program of interest for subsequent unattended recording. The first electrical contact is disposed within an elastically deformable wiper, and the elastically deformable wiper is adapted to expose the first electrical contact as it is engaged by the second electrical contact under an axially compressive load. In certain embodiments, the quinine-based and quinidine-based catalysts contain a thiourea at the C9 position. Many modifications are possible.
