Embodiments include storing graphics instructions at addresses in a memory in an original order, and storing in the memory pointers associated with each instruction pointing to the addresses of the instructions in the original order. A first pointer associated with a first graphics instruction may then be moved from pointing to a first address of the first graphics instruction to point to a second address of a second graphics instruction. Likewise, a second pointer associated with the second graphics instruction may be moved from pointing to the second address to point to the first address by accessing the first pointer before moving the first pointer to determine that the second pointer is to point to the first address (e.g., the address the first instruction points to before being moved). Afterwards, the instructions may be re-ordered into an optimized order for compiling, by switching them to different addresses according to the pointers.

The present invention is directed to systems, devices and methods for avoiding collisions and detecting objects proximate to a surface. In one embodiment, a system for collision avoidance includes at least one sensor adapted to sense an object above a lift device and a controller linked to the at least one sensor and linked to the drive components of the device and adapted to interrupt operation of the lift drive when the lift device approaches or touches the object. In another aspect of the invention, at least one controller is linked between at least one hand control and at least one drive adapted to move a lift device, the controller being adapted to interrupt operation of the drive when the lift device approaches or touches an object.
