A display device includes a plurality of pixels in matrix, a substrate on which the plurality of pixels are formed, and a support member under the substrate. Two shutter openings are formed in a shutter base. Each wavelet coefficient quantity represents different ones of the items by multiplying corresponding wavelet vectors. The distal end of the elongate member includes an end-effector, wherein a portion of the elongate member between the proximal end and the distal end transitions automatically from a first state to a second state when the portion is advanced out of the lumen of the tubular member, and wherein the portion is proximal of the end-effector.
