Abstract: A grid framework structure for supporting a load handling device operative to move one or more containers in a stack. The grid framework structure includes plural upright columns arranged to form plurality of vertical storage locations for containers to be stacked between upright columns. The columns are interconnected at their top ends by a first set of grid members and a second set of grid members, the second set running transversely to the first set to form a grid structure. A sub-group of upright columns rigidly joined together by at least one bracing assembly of diagonal braces form a braced tower. The sub-group of upright columns includes three upright columns with two of the three upright columns being laterally disposed either side of a middle upright column, and being rigidly connected to the middle upright column by the diagonal braces.

Abstract: A connector for connecting to at least three support elements of a three dimensional modular structure is disclosed. The connector includes a single body having a first connector portion for connecting a support element extending in a first direction; a second connector portion for connecting a support element extending in a second direction; a third connector portion for connecting a support element extending in a third direction, the first, second and third directions being substantially perpendicular to each other; and mounting projections each having a substantially flat mating face for mating with a corresponding mounting projection of an adjacent connector. Each connecting portion includes a key that is profiled for controlling the orientation of the support elements.

Abstract: An anti-seismic grid framework system including a grid framework structure configured for supporting a load handling device operative to move one or more containers in a stack. The anti-seismic grid framework system includes a seismic isolation system for reducing seismic forces acting on the grid framework structure, wherein the grid framework structure is supported by the seismic isolation system, the seismic isolation system including a superstructure and a substructure, and at least one base isolation device disposed between the superstructure and the substructure such that the at least one base isolation device suppresses movement of the superstructure relative to the substructure in a seismic event.

Abstract: A vehicle coolant pump with heat protection for the internal electronics and circuit boards for operation of the coolant pump. Gap fillers positioned adjacent said electronics and circuit boards transfer heat to the coolant fluid in the engine.

Abstract: Methods and systems for controlling the operation of a dual mode engine accessory, such as a dual mode cooling pump. The dual mode device has two modes of operation, an electric motor operation and a mechanical pulley-driven operation. A friction clutch mechanism controlled by the control system is utilized to switch between the two modes of operation. The speed of the electrical motor can be changed to be substantially the same as, or changed in the direction of, the speed of the mechanical pulley-driven system.

Abstract: An engine mounted fan clutch is disclosed that utilizes an actuator including two shape memory alloy actuation wires to engage and disengage a valve arm and ultimately the fan. The actuator also includes a controller and a position sensor to accurately determine the position of a valve arm. The fan clutch is part of a control system that continuously monitors the engine parameters and makes adjustments to keep the engine temperature within an acceptable range.
