Abstract: A convertible wheeled luggage handle comprises a housing holding a movable swivel handle, and the swivel handle is locked from moving outside the housing by a spring-loaded detent pin engaging a hole, and this detent pin can be raised from the hole freeing the swivel handle to pivot outside the housing by a retainer pin driven through the width of the swivel handle at the housing, and each end of this retainer pin protrudes slightly from each side of the swivel handle, and these protruding ends correspondingly sit into two accommodating slide members located along opposite lengths of the walls locking the swivel handle to the housing, besides locking and being the pivot point for the swivel handle these protruding pin-ends from the retainer pin have the additional function of sliding the swivel handle along the slide members in order to position the swivel handle outside/perpendicular to the housing.

Abstract: Apparatus consisting of a flat, two-dimensional array of laser/photo diodes; an optical storage card positioned below the array; and a mechanism to move the card in both the X- and Y-directions to position the laser/photo diode array over any one particular location on the card. A further mechanism serves to move the card in the X- and Y-directions and angularly to provide an initial alignment of the card with respect to the laser/photo diode array. Yet another mechanism moves the card in the Z-direction for focusing purposes. A laser/optical interface positioned between the laser/photo diode array and the card which is formed of an array of collimating and focusing holographic micro lenses (HOE) with surface diffraction patterns. An electronic section functions as an interface between a central processing unit (CPU) and the lasers and photo diodes of the array. The optical storage card is a thin, re-writable phase-change type.
