A MEMS array structure including a plurality of bulk mode resonators may include at least one resonator coupling section disposed between the plurality of bulk mode resonators. The system includes means for determining bright corrected pixel values for dark portions of an image corresponding to a first subframe and means for determining dark corrected pixel values for dark image portions of an image corresponding to a second sub frame of the image frame. The main spring is captured between two concentric sleeves one of which sleeves is fixed to the housing. After the predetermined period, purchaser information is used to produce a purchase wish list in a predetermined order.
