Abstract: A point-of-sale (POS) system for use in a retail establishment includes a computer system configured to track inventory and associate the inventory with a transaction in accordance with a transaction identifier. The computer system further includes a memory subsystem and a display device. The POS system includes a database operatively coupled to the computer system, a cash drawer operatively coupled to and controlled by the computer system, and an image capture device operatively coupled to the computer system and configured to transmit a selected captured image to the computer system for storage. The computer system is configured to store the captured image in the memory subsystem and operatively link the captured image with the transaction identifier upon receipt of a first predetermined signal. The computer system displays the transaction on the display device information, and upon receipt of a second predetermined signal, displays the captured image corresponding to the transaction on the display device.

Abstract: An apparatus for and a method of automatically heating foods in a microwave oven, capable of heating foods at an optimum state even when foods are to be continuously heated, by determining an ambient temperature from a variation in temperature of air introduced in a heating chamber through an air inlet port, determining a temperature increment in a heating chamber of the microwave oven and an amount of food, based on the determined ambient temperature, determining a primary heating time and an additional heating time, based on the determined temperature increment, and then determining an additional heating time, based on the determined food amount. As a result, it is possible to achieve an improvement in cooking performance. In addition, over-heating of the good is avoided, thereby enabling a reduction in electric power consumption and a reduction in cooking time.
