Abstract: An apparatus is disclosed for performing an additive manufacturing operation to form a structure by processing a photopolymer resist material. The apparatus may incorporate a laser for generating a laser beam, and a tunable mask for receiving the laser beam which has an optically dispersive element. The mask splits the laser beam into a plurality of emergent beams each having a subplurality of beamlets of varying or identical intensity, with each beamlet emerging from a unique subsection of illuminated regions of the mask. A collimator collimates at least one of the emergent beams to form a collimated beam. One or more focusing elements focuses the collimated beam into a focused beam which is projected as a focused image plane on or within the resist material. The focused beam simultaneously illuminates a layer of the resist material to process an entire layer in a parallel fashion.

Abstract: A microtome method and apparatus includes a microtome blade configured to oscillate in a direction transverse to a direction of advancing a cut, and a first flexure to support and guide the blade.

The other end portion of the second flexure is rotatably engaged by an eccentric driven by a rotatable actuator, which oscillates the blade in the transverse direction while effectively isolating non-transverse motion from the blade. The second flexure is configured to move independently of any guides or other stationary objects during oscillation.

Abstract: A cushion package structure includes at least a plate and two or more blocks. The plate is disposed within a storage box and the blocks are the same and pivotable with one another. As a number of blocks are connected with one another serially with various including angle between each adjacent two, one or multiple block sets may be formed thereby.

The blocks may be removed from the plate, rearranged, and redisposed on another plate, so that a storage space with a different shape may be defined.
