A noise mitigation boot that can be installed on or integrated into a miniature diaphragm pump to reduce the overall noise and improve sound quality during operation. The diaphragm pump includes a housing having first and second ports and an interior chamber, a pumping diaphragm disposed in the interior chamber and dividing the interior chamber into a pumping chamber and a backside chamber, a motor for reciprocating the pumping diaphragm for pumping air into and out of the pumping chamber, and flow passages connecting the pumping chamber to the first and second ports. The first port is configured for attachment to a flow line and the second port opens to an exterior surface of the housing. The noise mitigation boot has a muffler wall overlying the exterior surface of the housing. The muffler wall has formed therein a passage extending from the second port to the backside chamber for effecting fluid communication between the second port and the backside chamber.

A solenoid valve assembly includes an armature having a longitudinal axis and an ovular cross-section, the armature being moveable along the longitudinal axis from a first position to a second position, and a bobbin including a solenoid coil configured to electromagnetically move the armature when energized. The bobbin defines a recess also having an ovular cross section for receiving the armature and restricting lateral movement of the armature, thereby providing a linear actuation path for the armature along the longitudinal axis. A flux coupler and a flux bracket form a magnetic circuit with the bobbin to electromagnetically move the armature. The flux bracket has a pole piece with a commensurate ovular cross-section that limits the movement of the armature along the longitudinal axis, thereby determining a stroke length of the armature. During manufacture, the flux bracket, and therefore the pole piece, are moved relative to the flux coupler to set the stroke length.

A stackable dominoes game having stepped, tile-shaped playing pieces. The playing pieces have upper and lower levels and at least three segments. The segments are marked with first and second indicia and the pieces are played by stacking them atop one another so that only segments having matching indicia are in vertical contact. The indicia may be patterns of dots, such as a one-dot pattern and a four-dot pattern. A game board is provided having a grid for aligning the playing pieces thereon. Fence pieces are provided for defining a confined area of the grid for playing the pieces therein, depending on the desired degree of difficulty. Additional pieces are provided for other aspects of play.
