A cargo barricade for retaining oversized cargo within a truck bed includes a base component having front and rear sections which are secured to the front and rear surfaces of a tailgate respectively. The electronic device acquires a component file, a wiring file, a wiring group file, a first electrical rule file, and a second electrical rule file from a storage device. The emulsions and microemulsions are especially useful for treating hair, skin, or the underarm. This allows an image to be created to represent the electrostatic charge distribution across the region to which the sensor is directed. An input 21a of a control circuit 21 is connected to an output 19a of the sub-AD conversion circuit 19 and provides a control signal SCONT corresponding to the signal SDP.
