A non-volatile memory storage apparatus having a connector, an energy storage circuit, a power regulator and supply circuit, a non-volatile memory module, a memory controller and a buffer memory is provided. The carts have wheel supported upright frames with bottom supports for the products disposed at a level above the floor of the van and open fronts with front decks movable from a stowed retracted position to a generally horizontal operative position adjacent the bottom supports. Adjacently situated major cutting edges at each of the top and bottom sides are interconnected by corner cutting edges disposed along respective corners of the insert. A second portion of the waveguides act as output waveguides configured to carry the demultiplexed light signals away from the optical grating. The holder also includes a retainer connected to the sleeve adapted to retain a handle of a paint container and allow a weight of the paint container to be transferred to a remainder of the hand supporting a bottom of the paint container.
