Abstract: Systems and methods for detecting an out of balance condition for a washing machine are disclosed. The wash basket of the washing machine is rotated at a constant predetermined rotational speed. If the washing machine has an unbalanced load, the wash tub will strike the cabinet as the basket rotates in the wash tub. The tub strikes cause the wash basket to lose momentum. The inverter drive control system causes the inverter to provide more current through the motor phases to the motor to maintain constant speed. From the value of the current, the severity of the tub strikes during a test period can be determined. An out of balance condition can be detected and measured based at least in part on the severity of the tub strikes.

Patent number: 8813498
Abstract: A pressure sensor measures an organic Rankine cycle (ORC) working fluid pressure in front of a radial inflow turbine, while a temperature sensor measures an ORC working fluid temperature in front of the radial inflow turbine. A controller responsive to algorithmic software determines a superheated temperature of the working fluid in front of the radial inflow turbine based on the measured working fluid pressure and the measured working fluid temperature. The controller then manipulates the speed of a working fluid pump, the pitch of turbine variable inlet guide vanes when present, and combinations thereof, in response to the determined superheated temperature to maintain the superheated temperature of the ORC working fluid in front of the radial inflow turbine close to a predefined set point. The superheated temperature can thus be maintained in the absence of sensors other than pressure and temperature sensors.

Patent number: 8818584
Abstract: A system includes an interface module, a simulation module, and a resolution module. The interface module determines a captured state of vehicles traveling in a transportation network according to associated schedules and a proposed modification to the schedules. The captured state represents locations of the vehicles in the transportation network at a selected time. The simulation module simulates movement of the vehicles according to the proposed modification to the schedules. The movement of the vehicles is simulated from the selected time of the captured state of the vehicles. The resolution module determines potential ramifications from the movement of the vehicles that is simulated. The potential ramifications are representative of a simulated change in travel of the vehicles due to the proposed modification. The resolution module is further configured to use the potential ramifications for use in determining whether to implement the proposed modification in actual travel of the vehicles.

Patent number: 8818743
Abstract: An energy meter includes metering circuitry configured to monitor power consumption. The energy meter includes firmware including internal functions configured to control elements of the energy meter. Further, the energy meter includes an input/output port or a communications device configured to receive customized instructions and a processor. The processor controls the metering circuitry, receives customized instructions from the input/output port or the communications device. The customizable instructions provide additional control of the elements of the energy meter beyond the internal functions of the firmware. The processor interprets the customized instructions and executes the customized instructions using the internal functions of the firmware.

Patent number: 8819652
Abstract: A method and system for evaluating a system are described. A parameter space comprising one or more parameters corresponding to the system and/or an application executed on the system is defined. Additionally, one or more search functions for selecting a parameter from the parameter space to evaluate a desired characteristic of the system are determined. Further, at least one parameter from the parameter space is selected using the one or more search functions and the application is executed using the selected parameter. Subsequently, the execution of the application is monitored and metrics associated with the application are recorded. The method further includes iteratively selecting another parameter from the parameter space based on the recorded metrics and executing the application using the selected another parameter.

Patent number: 8818684
Abstract: Certain embodiments of the invention may include systems, methods, and apparatus for detecting failure in gas turbine hardware. According to an example embodiment of the invention, a method for detecting a failure in a gas turbine is provided. The method can include monitoring a parameter associated with the turbine, wherein the monitored parameter comprises at least one turbine bucket temperature, detecting an event associated with operation of the turbine, wherein the event is based at least in part on the monitored parameter, and initiating shutdown of the turbine upon detection of the event wherein the monitored parameter is above a predetermined value for at least a predetermined time duration.

Patent number: 8818683
Abstract: A method for operating a gas turbine engine includes coupling at least one sensor within the gas turbine engine to transmit a signal indicative of a vibration level of a rotor assembly within the gas turbine engine, detecting the vibration level of the rotor assembly based on the signal transmitted from the at least one sensor, comparing the detected vibration level to a predetermined vibration threshold, and generating an output if the detected vibration amplitude exceeds the threshold amplitude for a predetermined duration to facilitate identifying a gas turbine engine impulse event.
