Abstract: An invertible retaining wall block comprises a front portion, a rear portion and a neck portion connecting the front portion and rear portion. A projection extends outwardly from the block to interlock with similar blocks in adjacent courses of blocks. One or more notches are provided to the front portion in order to allow the base course of blocks to be placed in an inverted orientation with respect to subsequent courses because the notch provides clearance for the protrusion.

Abstract: A method, apparatus, and system are disclosed for displaying a multi-dimensional image. The present invention enables real time extraction and interaction with surfaces contained within a multi-dimensional image volume.

Abstract: A modular block wall system is comprised of a plurality of differently sized blocks. Each block comprises a front surface and opposing rear surface, a top surface and opposing bottom surface, and first and second opposing tapered side surfaces. Blocks further includes a recess extending inwardly from top surface and a protrusion extending outwardly from bottom surface. Blocks may also include a plurality of cores through the block from top surface to bottom surface. Blocks may further include a removable portion that can be cleaved off to create a decorative face on rear surface. The projection on each block is configured to fit within the recess of a block in the next lower course of blocks, regardless of the sizes of the respective blocks. Preferably, the varying lengths and heights of the blocks are evenly divisible by a uniform dimension. This allows modular blocks to be easily put together in any configuration to create a finished looking, yet non-uniform wall.

Abstract: a book for presenting a group of memorabilia items relating to a series of linked events and/or circumstances, includes a plurality of page panels, the page panels providing a number of page panel faces organized in pairs, each pair presenting a left hand page panel face and a right hand page panel face; a first of the pairs relating to a first event and/or circumstance, the first pair including a first right hand page panel face and a first left hand page panel face, either one or both including indicia representative of graphics and/or text descriptive of the first event or circumstance and the other including a first memorabilia receiving region to receive a first memorabilia item pertinent to the first event and/or circumstance; and the first memorabilia item positioned in the first memorabilia receiving region; a second of the pairs relating to a second event and/or circumstance which is linked with the first event and/or circumstance by a predetermined value, the second pair including a second right han

Abstract: A modular post block may include a core through the block body and three interlocking portions disposed on the inner perimeter surface of each block that project outward from one of the bottom surface or the top surface of each block. First and second interlocking portions are disposed on one surface of the inner perimeter and third interlocking portion is disposed on the opposite side. Blocks can be stacked in a column by horizontally rotating each successive block 180 degrees. Interlocking portions of a first block then project into the core of a second block and the third interlocking portion of the first block fits at least partially between two interlocking portions of the adjacent second block.

Abstract: A retaining wall block having a front surface, a rear surface, side surfaces, a top surface, and a bottom surface. Each side surface comprises a first section, a second section, a third section, and a fourth section, with the sections configured and arranged to allow a plurality of blocks to be arranged in a convex wall structure. The retaining wall block includes a projection that is configured to abuttingly engage a portion of a vertically adjacent block in a wall structure. Preferably, the block has a width/depth ratio in the range of about 1.87 to 2.67. The retaining wall block may be combined with an earth anchor for use in multi-course walls.
