In accordance with one aspect, a wall construction system includes a plurality of blocks configured to interfit in multiple courses with aligned interior voids being defined by the blocks. At least one shim is disposed between two of the plurality of blocks, wherein each shim includes a main body having a curved surface including a portion having a non-constant radius of curvature. In addition, a cementitious material is disposed in the aligned interior voids.

A block is disclosed that includes a top surface, a bottom surface, a pair of sidewalls, and a pair of endwalls. The block also includes a projection that protrudes beyond the top surface along a first axis and is symmetrical along a second axis and a third axis. The block also includes a recess that extends into the bottom surface along the first axis and is symmetrical along the second axis and the third axis. The block also includes a pair of trenches including a first trench and a second trench that are respectively defined by a recess extending into an endwall of the pair of endwalls. The pair of trenches both run along the first axis from a surface of the projection to a surface of the recess, and a first width of the first trench overlaps with a second width of the second trench along the third axis.

A theft-proof packaging system includes a product package having a clear compartment configured to encapsulate a product that is pneumatically vacuumized below a surrounding environment. A pressure sensor assembly is located within the compartment, the pressure sensor assembly including a pressure sensor, a power source electrically connected to the pressure sensor, and a transmitter electrically connected to the power source. The transmitter is configured to send a signal and a receiving unit located outside the compartment of the product package and disposed remote from the product package receives said signal and sounds an alarm. The pressure sensor assembly is configured to detect a change in pressure inside the compartment and then send the signal to the receiving unit activating the alarm. A passive RFID tag is located within the compartment and configured to be detected when it passes through a walk-through scanner activating a second alarm.

An L-shaped shear wall module including an L-shaped outer pattern plate, an L-shaped inner pattern plate, and connectors connected between the L-shaped outer pattern plate and the L-shaped inner pattern plate. The L-shaped outer pattern plate 100 and the L-shaped inner pattern plate 200 are arranged in parallel to each other. The L-shaped inner pattern plate includes a first inner pattern plate and a second inner pattern plate which are perpendicular to each other. A corner transition block is disposed at a corner of the L-shaped inner pattern plate. The corner transition block has a protruding surface protruding towards the L-shaped outer pattern plate. The protruding surface of the corner transition block and the inner surface of the L-shaped outer pattern plate jointly enclose a concreting cavity at the corners for concreting reinforced concrete. The present application also provides a shear wall and a construction method thereof.

Flexible extrusions of selected die patterns may be slid or snapped together to create bundles of slidably-interlocked extrusions that may be used to create structural components for architectural and a plurality of other construction purposes. Components such as standard rectangular construction beams, arches, domes, architectural trees, cylinders, molds, puzzling mazes, furniture, rollercoaster track, and other applications are illustrated and described in embodiments herein. Bundles of slidably-interlocked extrusions may be formed into a straight beam, bent into an arch, or twisted into other forms as desired. Bundles of slidably-interlocked extrusions may for example, comprise subsets of different length bundles of extrusions that may extend the length create long-span support beams or that may branch away at an angle from the starting beam to form a treelike structure.
