  • Patent number: 7126088
    Abstract: A control system for a cooking appliance enables a consumer to selectively program a cooking appliance through a control panel in a conventional mode based on established cooking times and temperatures, as well as in a simplified mode incorporating a minimal number of programming steps. In the simplified mode, the consumer selects a first, non-temperature related special features button and inputs a cook time. Immediately following input of the cook time, the control system starts a cooking operation. If the selected time is greater than a predetermined value, the control system automatically operates the cooking appliance in a cold start mode. An override is provided to disable the cold start mode if so desired. In addition, the control system allows a consumer to input both minimum and maximum cook times for the cooking operation.

  • Patent number: 6989515
    Abstract: An image stabilization apparatus and method for stabilizing the imaging of a high-performance optical system prone to imaging instabilities from thermal effects. Thermal instabilities within the lens, such as convection, can result in image placement errors in a high-performance optical system. The apparatus includes a heating element arranged on the upper surface of the optical system to provide heat to one or more gas-filled spaces in the optical system. An insulating blanket covers a portion of the optical system to uniformize the heating of the optical system and increase efficiency of the apparatus. The gas in the spaces is heated so that the warmer gases reside near the upper portion of the optical system, while the cooler gases reside near the lower portion of the optical system. This creates a stable thermal environment within the lens system, thereby stabilizing the imaging. Optionally gas can be flowed over the lower surface to keep heat from heating the lower portion of the optical system.

  • Patent number: 6958463
    Abstract: An electrical heater utilizes negative temperature coefficient material (NTC) and current imbalance between live and neutral ends of the heater to simultaneously protect the heater from the hot spot and mechanical intrusion into the heating cable. The NTC layer, separating the heating wire and current leakage conductor, becomes electrically conductive at the temperatures above 60° C., thus “leaking” the current to earth. The hot spot is detected by measuring the current imbalance between line and neutral connections of the heating cable. The mechanical intrusion into the heater, such as cable or insulation damage, water or sharp metal object penetration, is also simultaneously measured by the same current imbalance measuring system such as Ground Fault Circuit Interrupter (GFCI). The optional return conductor and metal foil/mesh hot spot detection shields cancel electromagnetic field. The heater may contain positive temperature coefficient (PTC) continuous sensor to control the temperature in the heater.

    Abstract: A popcorn machine for automatic activation of the popping cycle is disclosed. The popcorn machine has a kettle with a heating element controlled by a thermostat. Popping corn is placed in the kettle by a user. A control panel has a one pop button which when pressed initiates the full popping cycle. The one pop button activates a relay that closes a connection through the thermostat to the heating element. The thermostat regulates the temperature in the kettle and shuts off power to the heating element by opening itself and unlatching the relay after a predetermined temperature is reached to allow the completion of the popping cycle. If the kettle initially is over the predetermined temperature, the thermostat will be open and the relay will be unlatched, preventing power from flowing to the heating element. A timer relay may be connected to the first relay to allow the activation of the heating element during a set period of time allowing the kettle to cool. The kettle may also be connected to an oil pump.

  • Patent number: 6847015
    Abstract: Temperature control is made without the risk of contaminating object-to-be-processed and with high accuracy. Temperatures are metered out of contact with the objects-to-be-processed, and based on a metered result, estimated temperatures of the objects-to-be-processed are computed. Furthermore, estimation errors of the estimated temperatures are computed to correct the estimated temperatures. Based on a temperature recipe stating relationships between set temperatures and times and the corrected estimated temperatures, a heater is controlled.

  • Patent number: 6822199
    Abstract: A cooking appliance employing rapid cook technology includes a controller which automatically converts conventional cooking temperatures input by a user to rapid cooking temperatures. In accordance with the most preferred form of the invention, after a user enters a standard radiant cooking temperature into a control panel, an electronic controller subtracts a certain amount, preferably 25° F. (approximately 14° C.), off of the standard temperature. This reduced temperature is then shown in a display provided in the control panel. The controller will use this temperature as the actual cook temperature for the cycle. However, in order to assure food quality, this method is only employed in relatively short convection cooking cycles, such as a convection bake mode.

  • Patent number: 6818869
    Abstract: A multiple panel cooking oven having individual controls for combined conductive and radiant heating. Each panel comprises an upper heating element for conductive heating and a lower heating element for radiant heating to obtain uniform baking within a zone between panels in the oven. A control panel having displays and keypads interfaces with a processor which provides control signals for adjusting the temperature of the heating elements of the panels. Cooking energy efficiency is increased through the use of radiative and conductive heat transfer, to reduce bake times by significantly increasing heat transfer to the food products. Independent cook zones allow preparation of multiple products simultaneously under different cooking conditions. The oven, in one embodiment may include a convection heating mode of operation. In an alternative embodiment no convection mode is provided and the sole source of heat is provided by the conductive/radiant panels.

  • Patent number: 6818865
    Abstract: Food cooking oven, comprising a thermometric probe adapted to be introduced in the food to be cooked and to generate a signal that is representative of the detected temperature, in which said signal is sent to appropriate processing and display means capable of working out a final information (F) depending in a combined manner on both the detected temperatures and the cooking time. The oven is further provided with selection means adapted to send selective commands to said processing means. These processing means are furthermore adapted to automatically perform a comparison of said final information with said selective commands and issue respective signals, corresponding to the outcome of said comparison, towards appropriate indicator means. These signals are indicative of the period of time during which the food can be kept stored, ie. preserved after cooking, since they represent the bacterial count at the end of the cooking process.
