Abstract: A system for determining a crop edge and a self-propelled harvester using the system for automatic control are disclosed. The system comprises a camera that generates optical information of a front environment of the harvester. The system further includes a computing unit that analyzes the images using artificial intelligence so that a planted area of a field on which a plant crop is located may be delimited from a remaining residual area of the field, thereby determining the plant crop. In turn, the computing unit is further configured to determine the crop edge of the plant crop based on the determination of the plant crop and to automatically control the harvester based on the determination of the crop edge.

Abstract: The present invention is a free-standing vending machine that accepts currency and dispenses cards at certain values. The cards may be product coupons or trading cards. The machine may have multiple columns of cards, each column having cards with different values and offering different promotions. The cards are promoted by a sweepstakes game. A control board in the vending machine contains the rules of the sweepstakes game and determines whether a card is a winner or loser as each card is drawn from its respective column. A printer prints the winner/loser information and any prize amount on the cards as each card is drawn from its column. The latest card drawn from each column is displayed such that a customer can see whether the card is a sweepstakes winner or loser before purchasing the card.
