Abstract: Multiple exemplary systems for preventing jackknifing are disclosed. The systems comprise an electric motor for extending a shaft into a fifth wheel coupling when a tractor trailer is traveling at above a predetermined speed in a forward direction, physically preventing the tractor trailer from jackknifing. In order to avoid dependence on integration with a tractor, sensors on a trailer are used to determine speed without communication with the tractor or any instruments therein, via reception of one or more waves. When the trailer is determined to be traveling at below the predetermined speed in a forward direction, or at any speed in a backward direction, the shaft is retracted to allow the trailer to freely rotate with respect, to the tractor.

Abstract: A trash bag removal system is disclosed. The system includes one or more flexible liners arranged within a trash can. An overfilled trash bag may force the liner against one or more of the internal walls of the trash can such that the liner will slide upwardly along the internal wall as the trash bag is removed.
