The present invention is to provide an improved resilient bra cup structure with adjustable stiffness or softness, wherein the bra cup structure having at least four layers comprising a layer of stiff knitted fabric, a layer of meshed gel, a layer of resilient staple fiber, and a layer of soft knitted fabric. The peripheral area includes a plurality of conductive elements for connecting the plurality of sensing lines to the circuitry and at least one auxiliary sensing line extending over the peripheral area in the vicinity of the plurality of conductive elements and connected to the circuitry. A retaining pin portion at the control tip, extends between at least two of the second set of wires, allows the second set of wires to be extended from the tube and through the control tip, and prevents the second set of wires from being withdrawn from the control tip and into the tube. A flexible printed circuit board having a bending portion adapted for electrically connecting with the two display panels. User selection of a first button on the identification badge conceals visibility of the identification information displayed in the OLED display device. Each of the motor drivers includes a smoothing circuit, a control unit, an inverter unit and a cooler for cooling the inverter unit.
