A portable device includes a tray. An AF sensor detects the defocus amount of the interchangeable lens unit. The recesses are adapted to hold at least one article used in performing a push PEG procedure. Furthermore, implementations of the present invention provide methods for applying texture in an efficient, uniform manner. An electronic control circuit is added to hydraulic control circuitry and is configured to selectively interrupt the gravity down mode or power down mode of operation of the hydraulic system based on either a manual input or a sensed condition and switch to the other mode of operation. Three shaved inserts can be used for positioning in the neckline, underarm and center front regions of the pad, with each insert providing a different level of firmness and elongation to the pad.
