See some comments up top -- the patent is for a fundamentally different source of friction control. Ultrasonic, not mechanical/directional.

Which should make it more amenable to higher-frequency control than mechanical systems would be able to shift at (given they're limited by mass).

That said, having seen high-throughput parcel sorting, the modern tech is amazing and the reason we have flow-through logistics and 1-2 day delivery.

They've got it slowed way down in that video.

Here's a system at closer to full-speed: https://m.youtube.com/watch?v=nPWTfT9sO2Y&t=26s https://m.youtube.com/watch?v=JzURbt0qlqk&t=1m52s
