A front light includes a bar-shaped light source, and a light guide panel that introduces light from the light source through an end face and emits the light from an emergent surface. Longitudinal movement of drive members move lifting blocks up lifting ramps. The switch includes means for selecting an off-hook mode when the flap is in the retracted position or an on-hook mode when the flap is in the retracted position or a hands-free mode when the flap is in an intermediate position. After forming isolation trenches in the substrate between active areas below the strips of charge storage material, spacer-assisted patterning is used to form a pattern at the memory array region. The transceiver is configured to send an activation signal to the transponder thereby enabling the first transponder sensor to make a measurement and to hold the measurement.
