A flexible foam wedge, designed with a finger pocket and application tip that allows for direct support of the applicator from a finger digit particularly useful for the application of cosmetics. In this configuration, a track pitch TP of the optical disc is greater than or equal to 0. The aircraft has a flight computer that provides store release pitch data corresponding to the aircraft flight conditions. The voltage generator is configured to generate an erase word line voltage to be provided to a first word line of a selected sub-block of the sub-blocks and a cut-off voltage, higher than the erase word line voltage, to be provided to a second word line of the selected sub-block during an erase operation. The controller unit is used for generating a switch signal on receiving the high level signal, and sending a clear signal to the counter unit for clearing the counter unit.
