Patent number: 7461544Abstract: A method of detecting water induction in a steam turbine that may include the steps of: measuring the temperature of one of the steam lines of the steam turbine at regular intervals; recording the temperature measurements; and determining, from the recorded temperature measurements, whether there has been a sharp decrease followed by a gradual rise in the temperature of the steam line. The method further may include the steps of calculating the rate of change of the decrease in temperature of the steam line and the rate of change of the increase in temperature of the steam line. The sharp decrease followed by a gradual rise in the temperature of the steam line may include a decrease in temperature followed by an increase in temperature wherein the rate of change of the decrease in temperature exceeds the rate of change of the rise in temperature.Type: GrantFiled: February 24, 2006Date of Patent: December 9, 2008Assignee: General Electric CompanyInventors: Jitendra Kumar, Abhay S.

Patent number: 5577283Abstract: An energy saving method of operating a washing machine such that the amount of water added to the washer basket is proportionate to the weight of the articles to be washed includes the steps of determining a normalized inertia of the washer basket loaded with articles to be cleaned; determining an estimated weight of the load of articles to be washed based upon the normalized inertia value; and controlling a washer water supply system to add a load-specific volume of water to the washer basket, the magnitude of the load-specific volume of water corresponding to the estimated weight of the articles to be washed. An energy efficient washing machine in accordance with this invention includes an induction motor coupled to the washer basket, a washer water supply system coupled to the washer basket, and a washer controller coupled to the drive motor and the washer water supply system so as to respectively control operation thereof.Type: GrantFiled: March 20, 1995Date of Patent: November 26, 1996Assignee: General Electric CompanyInventors: Vivek V.

Patent number: 5560060Abstract: A system and method for adjusting the operating cycle of a cleaning appliance. In the present invention, a controller having a decision system receives turbidity and temperature measurements from a turbidity sensor and a temperature sensor and uses these measurements to adjust the operating cycle of the machine to the level of soil of the articles to be washed, the rate of soil removal, and the temperature of the water used for washing. In its preferred form the decision system is a fuzzy system that includes a fuzzy rule base fired as input values from the liquid temperature and liquid turbidity sensors are received. The decision system matches the rules in the fuzzy rule base to the input values and outputs a confidence value, which is used by the decision system to adjust the operating cycle.Type: GrantFiled: January 10, 1995Date of Patent: October 1, 1996Assignee: General Electric CompanyInventors: Mark E. Dausch, Roger L. Hoffman, Gregory O. Miller, David A. Schneider, Vivek V. Badami

Patent number: 5433079Abstract: A method for automated control of a steam turbine prewarming procedure employs fuzzy logic to generate a control signal for a turbine regulatory function, such as steam supply. The method includes the steps of determining a plurality of turbine condition parameter signals; generating a plurality of regulatory control directions; generating a weighting factor to be assigned to each of said regulatory control directions by means of a fuzzy inference calculation in accordance with an operator-selected fuzzy logic profile, and applying the weighting factors to the regulatory control directions to produce the turbine regulatory function control signal. The turbine regulatory function control signal is applied to a respective function controller in the steam plant such that the selected turbine prewarming profile is implemented.Type: GrantFiled: March 8, 1994Date of Patent: July 18, 1995Assignee: General Electric CompanyInventors: Vivek V.

Patent number: 5375437Abstract: An out-of-balance condition detecting system with a lid actuated switching assembly for interrupting operation of a washing machine upon detection of an out-of-balance (OOB) condition or upon a lid of the washing machine being open. The system includes pneumatic generating units for generating a predetermined fluidic pressure in response to excursions of a tub of the washing machine during a spin cycle; an actuator which is fluidly coupled to such generating units for providing an actuating position corresponding to the OOB condition; and a switching assembly which includes a switch responsive to the actuator in its actuating position to interrupt the OOB condition. The switch is further responsive to the lid to deenergize the motor upon the lid being in an open position. The switch which can be either mechanically or magnetically actuated may be designed such that once the OOB condition has been detected, a user is required to open the lid in order to reset operation of the washing machine.Type: GrantFiled: September 20, 1993Date of Patent: December 27, 1994Assignee: General Electric CompanyInventors: Mark E.

Patent number: 5284523Abstract: A fuzzy logic based control method reduces the amount of water used by a washing machine or dishwasher during a cycle. A sensor detects when the washer has adequate water by monitoring the behavior of the washer pump motor as fresh water is coming in. There is a characteristic oscillation of the magnitude of the motor current as the pump cavitates during this operation, which diminishes when the washer is properly filled. By using fuzzy logic to sense this point of diminished or ceased cavitation and shutting off the incoming water, substantial savings of water can be achieved.Type: GrantFiled: May 1, 1992Date of Patent: February 8, 1994Assignee: General Electric CompanyInventors: Vivek V.
