Abstract: Systems and methods for providing a consumption network are provided. A method according to the invention may include receiving purchase information on a mobile device and recording the purchasing information. The information may be transmitted to a central database. At the central database, the information may be recorded and transmitted from the central database to a pre-determined group of users. Alternatively, the information may be transmitted to a group of users directly from the mobile phone associated with the purchasing.

Abstract: A switch controlling device for a serial communication port and a light communication port having an asynchronous communication part, a switch, a micro-controller, multiplexers, an EIA driver, and a light signal input/output part. The switch controlling device for the serial communication port and the light communication port is driven by a user selecting the serial communication port or the light communication port, after both the serial communication port and light communication port have been installed in a computer system.

Abstract: A wave guide system of a microwave oven is provided, comprising a cavity containing a food to be cooked and having a pair of microwave feed openings formed in one wall thereof; a magnetron having an antenna and positioned between the microwave feed openings in spaced apart relation to the wall having the feed openings, to generate microwaves having a wavelength of .lambda..sub.g ; and a waveguide provided to cover the feed openings, support thereon the magnetron and guide the microwave through the feed openings into the cavity and having a short circuited surface which is spaced apart from the antenna by a distance of .lambda..sub.g /4 and parallel to the antenna. With this arrangement, the microwave generated in the magnetron produce standing waves in the waveguide, and then are emitted into the cavity through the microwave feed openings of the cavity, thereby uniformly heating a food in the cavity.

Abstract: An improved heating time control apparatus and method thereof for a microwave oven capable of advantageously computing an optimum cooking time without controlling the amount of food to be cooked. The invention includes: a sensor for detecting a predetermined physical, i.e.

Abstract: A microwave oven with a function for drying tableware dryer. The microwave oven includes a heater and a magnetron controlled by a microcomputer, a tableware basket holder detachably equipped with a tableware basket, a water bucket and a plate. A tableware basket holder sensing section is mounted for sensing the tableware basket holder when it is inserted in a cavity of the microwave oven. The tableware drying function is performed by driving the heater under the control of the microcomputer when a tableware basket holder sensing signal is generated from the tableware basket holder sensing section.

Abstract: A temperature sensor connecting device for a microwave oven integrating a stirrer fan on the ceiling is arranged to plug a temperature sensor through the stirrer fan shaft into a recepticle provided on the external side of the top cover so that the temperature sensor inserted in the food on a turntable rotates following the rotation of the food under heating with no cause of twisting.

Abstract: A door latch assembly for use in a microwave oven comprises a latch pawl secured to the inside of the door, a revolving plate having integrally molded therewith a push projection, a hook-shaped projection having a stop surface formed thereon, a projected bar and a U-shaped spring support member having a panel spring positioned longitudinally therein. The stop surface of the hook-shaped projection prevents further rotation of the revolving plate by abutting the surface of the spring support member.
