  • Publication number: 20030202558
    Abstract: A wireless cooking thermometer consisting of a transmitter unit and a receiver unit. The transmitter unit senses the cooking temperature of food item and periodically transmits the temperature as an RF signal to the receiver unit. The receiver unit compares the current food temperature to preprogrammed values representative of different levels of doneness and provides visual and audible alerts when the food temperature reaches one level of doneness below the selected level, when the food reaches the selected level of doneness, and again when the food reaches an overcooked level. A display on the receiver unit has an ascending bar graph to visually depict the progress of cooking through the various cooking levels. The display also has indicia to display the type of meat selected, the current temperature of the sensing probe, the temperature corresponding to the selected level of doneness and an overcook indicator.

  • Patent number: 6630655
    Abstract: A heating chamber has a width in a direction of a two-head arrow X, a depth in a direction of a two-head arrow Y and a height in a direction of a two-head arrow Z. An infrared sensor includes 25 infrared detection elements each having a field of view. Since the 25 infrared detection elements are arranged, five by five in directions Y and Z, on the heating chamber's bottom plate there are projected a total of 25 fields of view, five by five in directions Y and X. Thus the bottom plate has any area thereof covered by one of the 25 fields of view.

  • Patent number: 6616331
    Abstract: A test wafer for use in temperature prediction is prepared. The test wafer includes: first semiconductor layer formed in a crystalline state; second semiconductor layer formed in an amorphous state on the first semiconductor layer; and passivation film formed over the second semiconductor layer. Next, the test wafer is loaded into a device fabrication system and then heated therein at a predetermined period of time. Thereafter, a recovery rate, at which part of the second semiconductor layer recovers from the amorphous state to the crystalline state at the interface with the first semiconductor layer, is calculated. Then, a temperature of the test wafer that has been heated is measured according to a relationship between the recovery rate and a temperature corresponding to the recovery rate.

  • Publication number: 20030156621
    Abstract: A temperature sensor (10) for use in a cooking appliance of the kind in which an electric heater (1) incorporating at least one heating element (5) is located behind a cooking plate (2). The temperature sensor is adapted to be located between the at least one heating element and the cooking plate. The sensor (10) comprises a sensing element (13) having an electrical parameter which changes as a function of temperature and a housing (12) for the sensing element. The housing has a first surface region (15) with high thermal radiation absorption relative to a second surface region (16). The sensor is adapted to be located with the first surface region (15) of the housing facing substantially towards the cooking plate (2) and the second surface region (16) facing substantially towards the at least one heating element (5).

  • Patent number: 6590192
    Abstract: A microwave oven determines an appropriate time to stop heating even if multiple food items are placed in the heating chamber. After any position on the bottom surface of the microwave oven reaches 75 deg C., a search is made for any other position having a temperature of at least 70 deg C. If such a position is detected, heating is concentrated on that position until it reaches 75 deg C. When all food-containing positions in the microwave oven have reached a temperature of at least 75 deg C., the heating operation performed by the magnetron is stopped.

  • Patent number: 6586714
    Abstract: The microwave oven includes an infrared sensor for detecting the temperature of a food within a heating chamber. The infrared sensor has a field of view within the heating chamber. The infrared sensor is capable of moving the field of view. The food is often placed in the central region of the heating chamber. Therefore, when cooking is started, the field of view of the infrared sensor first scans the central region of the heating chamber.

  • Publication number: 20030112846
    Abstract: A thermometer configured to measure the temperature of a medium. The thermometer typically includes a temperature sensor positioned within a sealed sensor chamber. The sensor chamber, in turn, is positioned within a heat storage chamber. The heat storage chamber contains a thermal insulator. Heat energy thus is exchanged between the medium and the temperature sensor through the thermal insulator contained within the heat storage chamber so as to slow reaction of the temperature sensor.

  • Patent number: 6563097
    Abstract: A microwave oven heats all food in an appropriate manner even if food items are simultaneously placed at multiple locations in a heating chamber. An auxiliary antenna is periodically stopped at an orientation corresponding to a position where a lowest temperature was detected at the start of the heating operation. Between stopped periods, the auxiliary antenna is rotated for a period to apply heat evenly to all food in the oven. If multiple low-temperature points are detected, the central position of these multiple low-temperature points is used for applying concentrated heat.

  • Patent number: 6511223
    Abstract: A sensor link is disclosed that simplifies connections between multiple temperature sensors positioned on a test board and a data logger that stores temperature information received from the temperature sensors while passing through the conveyor oven. In one embodiment, the sensor link includes multiple input ports for connecting to the temperature sensors. Conductors within the sensor link connect the multiple temperature sensors to an output port. In one aspect, a single cable extends between the sensor link and a data logger. The data logger stores temperature information received from the temperature sensors while the test board is passed through a conveyor oven. The sensor link can also have additional temperature sensors for providing additional temperature information about the conveyor oven. For example, an ambient temperature sensor may be positioned on the sensor link to provide the ambient temperature of the conveyor oven.

  • Publication number: 20030007544
    Abstract: The invention provides a dual thermometer system for the measurement and display of temperature data taken at two separate locations within an oven. In one aspect, the invention provides an elongated probe connected with a flexible electronic cable. The probe houses two temperature sensors—one for sensing internal food temperature, one for sensing inside oven air temperature. The sensors are space apart within the probe such that the one sensor can be positioned substantially within a food item and the other sensor can positioned substantially outside of the food item and within the oven. Signals from the sensors are relayed from the probe and through the cable; external electronics may attach to the cable to acquire the signals and display associated temperatures. In another aspect, signals from temperature sensors are relayed from the probe and through the cable to a first wireless termination.
