Publication number: 20150292134Abstract: A method and modified clothes washer provides for an overnight dry cycle. A standard washer is modified to draw air from external to the housing, direct the air into the tumbling drum, and remove the air with a blower to exhaust from the housing during an extended drying period overnight. By selecting this option, the consumer need not move the clothes from the washer to the dryer.Type: ApplicationFiled: June 25, 2015Publication date: October 15, 2015Inventors: Jerrold S. Dale, Brian L. Mallory, Thomas Holzen, Gautam Subbarao, Anthony Ray Brieschke, Eliel Fresco Rodriguez

Patent number: 9109318Abstract: A blower is provided having a fan element that is directly connected to a drive shaft. The drive shaft is attached to a wash drum and is rotated by a washer motor. When the washer motor rotates the drive shaft, the fan element also rotates and can move air through the washing machine appliance without the use of an additional blower motor. Alternatively, the fan element of the blower is directly connected to a motor shaft extending from the motor, such that when the motor shaft is rotated, the blower can move air through the washing machine appliance without the use of an additional blower motor.Type: GrantFiled: May 28, 2013Date of Patent: August 18, 2015Assignee: GENERAL ELECTRIC COMPANYInventors: Ashutosh Kulkarni, Gautam Subbarao, Chang Hyun Lee

Publication number: 20120065806Abstract: The present subject matter relates to methods and apparatus for measuring energy usage in an appliance, particularly a washing appliance. A display, that may be a home energy monitor, is associated with the appliance. The appliance may include an AC-DC power supply and a controllable inverter configured to supply power to a motor associated with the appliance. Real power consumption is calculated by a controller that may also be used to control the inverter and other operational aspects of the appliance and causes the calculated real power to be displayed on the display.Type: ApplicationFiled: May 6, 2011Publication date: March 15, 2012Applicant: GENERAL ELECTRIC COMPANYInventors: Steven Michael Recio, Gautam Subbarao, Richard Dean Suel, II, Chad Michael Helms

Patent number: 7652265Abstract: An air treatment system includes a housing defining a chamber, and an ultraviolet lamp positioned within the chamber. The housing further defines an air inlet at a first end portion of the housing and an air outlet at a second end portion of the housing opposing the first end portion. The chamber provides flow communication between the air inlet and the air outlet. At least one ultraviolet lamp is positioned within the chamber. The at least one ultraviolet lamp is positioned about a first axis and includes a first end and a second end spaced with respect to the first end along the first axis. The at least one ultraviolet lamp is configured for facilitating inactivating contaminants within air channeled through the chamber.Type: GrantFiled: December 11, 2006Date of Patent: January 26, 2010Assignee: General Electric CompanyInventors: Gautam Subbarao, Mark Wayne Wilson, Anand Ganesh Joshi, Hemachandran Umakanthan, Ramnath Vaidyanathan

Patent number: 7065420Abstract: A system and method for automatically estimating the optimized cost of a part during the course of design of the part on a computer-aided design (CAD) system by a designer. The method includes extracting parametric features of a current design from the CAD system. Manufacturing cost drivers are identified on the basis of the parametric features. The manufacturing cost drivers are translated into costs using process models. The costs are simultaneously optimized with respect to a plurality of operations within specified machine constraints using an algorithm with dynamically linked structures to obtain estimates of optimized costs and cost reasoning. An estimate of optimized costs and cost reasoning is fed back to the designer as an output display on an output device.Type: GrantFiled: November 19, 2004Date of Patent: June 20, 2006Assignee: The Board of Trustees of the University of IllinoisInventors: Michael L.
