Abstract: This unique method to remind drivers that there is a child/pet inside of vehicle consists of two cues, one visual and one physical. The visual serves as a constant reminder while the driver is in the vehicle. The physical cue reminds the driver at end of the trip. The two cues work together to create a simple yet effective reminder that there is a child/pet still inside the vehicle.

Abstract: At a party/gathering, people are served drinks in identical vessels (children's cups, beer bottles, wine glasses . . .) and it is very difficult to determine whose drink is whose. Mark cups, glasses, and bottles with the drink-marking device (special purpose drink marker) to identify drink ownership. And when the party is over, apply cooking oil to marks 5 minutes before cleaning/putting into dishwasher for a mark-free glass that is ready to use at the next party.
