1) Luggage doesn’t come out until your phone indicates that you’re ready or went through a checkpoint. This way you can coordinate the variable time you have (eg detained or in a long line) with the baggage before it is placed on the chute. The throwers simply sort the luggage by having cleared to go down the chute, as you move through the process. They can also see on a screen for each luggage where each person is in the process. Usually it’s far easier to delay luggage than expedite it.
2) People are woken up before descent begins and the seatbelt sign is turned on. For the vast majority of flights, this can be predicted in advance. Switching happens in an orderly fashion, and people end up near their baggage before the flight ends. They actually can even pay per minute for naps in the back, requesting a sleeper seat is like requesting a flight attendant, except it lights up the request for the next seats in the back, and whoever accepts your offer can even get a cut of the $. Typically though the airlines would sell the back seats for cheaper (because you have to move) and charge far more for the people who want to sleep on the flight. Often a good relaxed sleep is worth far more and is an impulse buy on the plane.
Anyway, good luck with your patents, I hope it works out for you.
This doesn't always work. Many times the luggage is at the carousel quicker than you are.
As for '2', airlines don't like people switching seats, before take-off they use the 'weight and balance' argument, and after take-off because it will slow things down tremendously when de-planing to sort out where everybody's carry on luggage is.
