Abstract: A system and method for providing flow rate compensation in a washing machine. This invention provides flow rate compensation by monitoring the flow rate of the inlet liquid and the agitator load while agitating. A controller uses a flow rate compensation algorithm to compensate for the varying flow rate of the inlet liquid and an adaptive fill algorithm to determine an optimal level of liquid to be added to the washer basket and washer tub during a wash cycle operation.

Abstract: A system and method for sensing the dryness of clothing articles in a clothes dryer. In one embodiment, the clothes dryer uses a temperature sensor and a phase angle sensor to determine the dryness of the clothing articles as a function of the heated air temperature and the motor phase angle. In another embodiment the clothes dryer uses a humidity sensor to determine the dryness of the clothing articles as a function of the humidity of the heated air temperature. In a third embodiment the clothes dryer uses a temperature sensor, a phase angle sensor, and a humidity sensor to determine the dryness of the clothing articles as a function of the heated air temperature, the motor phase angle, and the humidity of the heated air temperature.

Abstract: A temperature sensor system for a household appliance, such as a microwave oven, that provides for a non-contact self-calibrating measurement of the temperature of an object disposed in a chamber of the appliance. The system comprises an infrared transmitter and an infrared receiver, as well as a distribution apparatus for coupling the transmitter and receiver to the appliance chamber. A scan pattern of infrared radiation is provided for the chamber and the detected infrared radiation from the chamber is used by a processor to generate an accurate measure of the temperature of the object in the chamber.

Abstract: A fuzzy logic controller is compiled into values in a look-up table such that the table may be used for adjusting a process dependent upon the state variables. The look-up table may be generated by use of a Mean of Maxima (MOM) technique for defuzzification. Alternately, an approximate Height Method (HM) may be used to provide defuzzification. The MOM and HM techniques allow fuzzy logic control without executing any rules in run-time. A further alternative uses an exact height method and minimizes the number of rules which are executed in run time.

Abstract: This invention provides a system and method for determining a level of liquid to be supplied for a wash cycle operation in a washing machine given a clothes load and clothes type. The liquid level setting is determined by measuring the time to fill the washer basket and the washer tub with a predetermined initial level of liquid, measuring a change in the level of liquid in the tub and basket after soaking for a predetermined time, and applying a fuzzy logic algorithm to the measured values.

Abstract: A variable volume oven that can be modified to adjust its volume according to the cooking load. The volume of the oven is able to be adjusted by providing a heating element that is vertically adjustable within the oven to a position that provides better convective and radiative heating to the cooking load.

Abstract: A method and apparatus for detecting the relative proportion of various fabric types present in a clothes load in a clothes washer are provided, in which a set of fuzzy logic membership functions is defined at each clothes load weight across a range of expected load weights to be handled by the clothes washer, with the set of membership functions representing various fabric types that might be present in the clothes load. The membership functions are defined at least in part by a washer operating state that is to be sensed during initial washer operation, and the method includes obtaining a value for the clothes load weight, sensing a value of the washer operating state, and determining a degree of fulfillment of the sensed value in each of the membership functions defined for that given clothes load.

Abstract: A fuzzy logic supervisory control architecture for aircraft engines includes a series of fuzzy proportional integral controllers each designed for a specific operating range and a fuzzy logic hierarchical controller for combining the fuel flow derivative outputs of the individual controllers. The hierarchical controller utilizes fuzzy logic on the input space fuzzified to linguistic values for engine temperature, power turbine speed and spool acceleration to determine a weighting to be given to each of the controller outputs for fuel flow derivative.

Abstract: The present invention discloses a device and method for separating lint particles in a clothes dryer. In the present invention, the device and method use a cyclone to separate the lint particles. The cyclone includes a housing container having an inlet port and an outlet port. A screen is positioned about the inlet port. A tubing extends through the outlet port into the housing container. A drawing means draws moisture and lint laden air from the clothes dryer through the screen. A circulating means circulates the moisture and lint laden air in the housing container about the tubing. A removing means removes the moisture and lint laden air from the housing container and retains any lint particles within the housing container. The cyclone improves upon the efficiency of accumulating lint particles without compromising the passage of air flow in the exhaust duct and improves upon the passage of air flow without decreasing the amount of lint particles being trapped.

Abstract: An energy efficient washing machine includes a control system that provides a cleansing fluid level that is optimized for effective cleaning of the soiled articles and includes a closed loop adaptive water level controller that controls the addition of water into the machine. The adaptive water level controller includes an agitator load signature monitor and an agitator work-determining processor, the processor being coupled to the agitator load signature monitor and a cleansing fluid supply system and adapted to generate a fluid supply control signal in correspondence with an agitator work signal, which signal is generated by the processor in correspondence with iterative respective agitator load signature values corresponding to strokes of the agitator.

Abstract: An energy efficient washing machine includes a cleansing fluid supply system, a washer basket having an agitator device for displacing the articles to be cleansed within the basket, and a closed loop water level controller coupled to the cleansing fluid supply system and to the drive system for the agitator. The fluid supply system includes a fill nozzle designed to provide a clothes-positioning spray pattern that serves to maintain the articles evenly distributed in the basket to enables the load sensing systems of the closed loop adaptive water level controller to function to accurately provide the optimal water level for cleansing. To accomplish this positioning of the articles to be cleansed, the fluid fill nozzle typically provides a fan discharge of fluid passing therethrough and is disposed at a cant angle with respect to the direction of rotation of the basket such that the fan discharge covers an area between the agitator assembly and the sidewall of the basket.
