Abstract: A manipulative three-dimensional puzzle including a shell member formed with a plurality of tracks including a first set of tracks and a second set of tracks, the first and second sets of tracks intersecting each other at a plurality of crossroads, the first and second sets of tracks together extending at least partially over a height, length and width of the shell member, and a plurality of puzzle pieces and a plurality of spacers movably positioned in the first and second sets of tracks, wherein for each track at least one spacer is between two puzzle pieces, and wherein moving one of the puzzle pieces in one of the tracks causes all the puzzle pieces and spacers in that track to move together along that track.

Abstract: A sensor assembly including a sensor including an actuatable element that causes an operation when actuated by a sensor actuator, the sensor including a holder, and a biasing device that imparts a biasing force against the holder that compensates for relative movement between the actuatable element and the sensor actuator so as to maintain the actuatable element substantially at a predetermined spatial position with respect to the sensor actuator.

Abstract: Apparatus including a vending machine compartment including a dispensing door openable to permit removal of merchandise from the compartment, the compartment being pivotedly connected to a box assembly, and wherein the dispensing door includes a link element that is constrained to move along a track formed in the box assembly such that the dispensing door is not openable at a first portion of the track and is openable at a second portion of the track.

Abstract: A device for preventing door slamming including a housing that has a bore formed therein, a control element that slides in the bore, the control element having a bore formed therein, a plunger that slides in and out of the bore of the control element, the plunger being biased against a distal end of the bore of the control element by a biasing device, and a stopper element received in the plunger and extending into the control element, wherein a slamming force applied on the plunger dislodges the stopper element from the plunger so that the stopper element becomes lodged in the control element and the housing, thereby preventing the control element from sliding in the bore of the housing.
