1) Air-washing a car that was too long in the hot Texas summer sun.
You open all the car's windows and drive for 2 minutes, then turn the A/C system's fan (only) on for another 1 minute, then close all the windows and turn the real A/C on, unless you are within 1 minute of your final destination, in which case, you can just turn the fan off and look for parking.
2) Something to attach your ski-poles to, when you a) get on the ski lift, b) open your water bottle, or c) want to help your friend back up!
3) A car seat that let you sit in it outside the car, and then it takes you to the inside like a toaster oven?
4) Using a Pi Pico RP2040 to implement the DCC protocol in the Programmable I/O (PIO), yes, just like that!
5) There are many clipboard tools that can capture and provide many items to use in the copy/paste work stream...but where is the "select text", ctrl+c to copy it and then wonder over to another part where you select some new text and do a ctrl+swap? We always have to move something "A" to a third location "C" to move "B" to "A" and then "C" into "B" if you want to swap "A" and "B". So this patent will make sure that "C" is never seen!
