Mechanical tree shakers and how to protect the fruit from bruising

This one is "Cherry Harvest", showing 2 movile shakers with giant arms to receive the fruit. Each arm has a rectangular plastic fabric surface that are located under the branches and can move to spill the collected fruit on a recipient: http://www.youtube.com/watch?v=X642dSCgxqU&feature=related

MunckhofMachinery has a similar concept in this video: http://www.youtube.com/watch?v=25YhYagC15Q&feature=related .

This olive shaker (Savisal, from Portugal) deploys an umbrella-like device below the tree before shaking:

In here you see a net mounted on a mobile structure intended for olives or maybe other fruits:

Finally, my preferred cheap solution: bubble wrap fabric.
