    Abstract: A microwavable material having a structure that may be used to enhance the browning and crisping, and thus improve the taste and appearance, of a food item cooked therein. The material may be in the form of a sheet material or formed as a container such as a bag, pouch, or other suitable structure. The material may comprise one or more features that help bring the material into close contact with the food item and help conform the bag around the food item. Furthermore, the material may comprise a structure that avoids substantial contact with liquid released by a food item, may have a venting system suitable for the exiting of moisture, may have a coating, a transparent surface, and when formed as a container, may have a gusseted surface.

    Abstract: An outer portion of one or more layers of microwave interactive material, which is for becoming hot when exposed to microwave energy, is arranged in a manner that seeks to advantageously control heating, so that the outer portion of the microwave interactive material can safely be adjacent the periphery of a turntable tray. The turntable tray can be heated by the microwave interactive material so that a peak thermally induced stress occurs in the turntable tray at a position proximate the periphery of the tray. The layer(s) of microwave interactive material are configured in a manner so that the peak thermally induced stress is less than a predetermined amount.

  • Publication number: 20090184399
    Abstract: A system for and method of processing, i.e., annealing semiconductor materials. By controlling the time, frequency, variance of frequency, microwave power density, wafer boundary conditions, ambient conditions, and temperatures (including ramp rates), it is possible to repair localized damage lattices of the crystalline structure of a semiconductor material that may occur during the ion implantation of impurities into the material, electrically activate the implanted dopant, and substantially minimize further diffusion of the dopant into the silicon. The wafer boundary conditions may be controlled by utilizing susceptor plates (4) or a water chill plate (12). Ambient conditions may be controlled by gas injection (10) within the microwave chamber (3).

  • Patent number: 7319213
    Abstract: Indentation patterns in microwave packaging materials can enhance the baking and browning effects of the microwave packaging materials on food. The indentation patterns can provide venting to either channel moisture from one area of the food product to another, trap moisture in a certain area to prevent it from escaping, or channel the moisture completely away from the food product. The indentation patterns can cause the microwave packaging material underneath a food product to be slightly elevated above the cooking platform in the base of a microwave. The indentation patterns can lessen the heat sinking effect of the cooking platform by providing an air gap for insulation. Elevating the base of the microwave packaging material further allows more incident microwave radiation to propagate underneath the microwave packaging material to be absorbed by the food product or by microwave interactive materials in the microwave packaging material that augment the heating process.

  • Publication number: 20070278220
    Abstract: A method, apparatus, and computer usable program code for detecting a presence of metal objects placed in a microwave cooking unit. A metal detection unit is activated to scan for the presence of a metal object placed into a cooking area of the microwave cooking unit. In response to receiving an indicator of the presence of a metal object from the metal detection unit, the process generates an alert indicating the presence of the metal object.
