20130251542 | Speed Control - A pumping system for moving water of a swimming pool includes a water pump, an infinitely variable speed motor, and an arrangement for operating the motor. In one example, the pumping system includes a memory configured to store a plurality of retained speed values, an arrangement for providing a plurality of retained speed values to the memory, and an arrangement for reading a selected one of the plurality of retained speed values from the memory. In addition or alternatively, the pumping system includes a storage medium for digitally storing a plurality of pre-established motor speed values and an arrangement for receiving input from a user to select one of the pre-established motor speeds. In addition or alternatively, the pumping system further includes an arrangement for restarting operation of the motor at a previously selected speed value when power supplied to the motor is interrupted during operation of the motor. A method for controlling the pumping system is also provided. | 09-26-2013 |
20140322030 | Control Algorithm of Variable Speed Pumping System - A pumping system includes a pump for moving water. In one aspect, this is in connection with performance of an operation. The system includes a variable speed motor operatively connected to drive the pump. A value indicative of flow rate of water is determined and the motor is controlled to adjust the flow rate indicative value toward a constant. A value indicative of flow pressure is determined and the motor is controlled to adjust the flow pressure indicative value toward a constant. A selection is made between flow rate control and flow pressure control. In another aspect, the pump is controlled to perform a first operation, and is operated to perform a second water operation. Control of operation of the pump to perform the first water operation is altered in response to operation of the pump to perform the second operation. | 10-30-2014 |
20140363308 | Pumping System with Power Optimization - The present invention provides a pumping system for moving water of a swimming pool, including a water pump and a variable speed motor. In one example, a target volume amount of water and an operational time period is provided, and the operational time period is altered based upon a volume of water moved. In another example, operation of the motor is altered based upon the volume of water moved. In addition or alternatively, a target flow rate of water to be moved by the water pump is determined based upon the target volume amount and a time period. In addition or alternatively, a plurality of operations are performed on the water, and a total volume of water moved by the pump is determined. In addition or alternatively, an optimized flow rate value is determined based upon power consumption. | 12-11-2014 |

20110061673 | ADJUSTABLE-BARREL CURLING IRON - An adjustable barrel, a barrel-adjustment assembly, and an adjustable distal tip assembly. The barrel is radially adjustable between an expanded position and a contracted position having different diameters. The barrel-adjustment assembly includes a barrel cam, a gear-set, and a rotary adjustment ring. The barrel cam rotates to unwrap and wrap the barrel thereabout between the expanded and contracted positions. The gear-set rotationally drives the barrel cam. The adjustment ring can be longitudinally translated from a disengaged position to an engaged position. In the disengaged position the gear-set is disengaged (but an anti-rotation assembly is engaged) and in the engaged position the gear-set is engaged (and the anti-rotation assembly is disengaged). Once in the disengaged position, the adjustment ring can be rotated, which causes the engaged gear-set to rotate the barrel cam, which in turn wraps and unwraps the barrel about the cam into increased or decreased diameters. | 03-17-2011 |
20110108051 | Ultrasonic Hairstyling Device - A device for styling hair includes a handle and a barrel extending from the handle. The barrel has a styling surface spaced from the handle, and the styling surface is configured for winding the hair around the barrel. The device further includes a heating element in thermal communication with the barrel to transfer heat to the hair via the styling surface of the barrel, and an ultrasonic transducer configured to generate ultrasonic vibrations. The ultrasonic transducer is disposed within the barrel to transmit the ultrasonic vibrations to the hair via the styling surface of the barrel. | 05-12-2011 |
20110108053 | Ultrasonic Hairstyling Device - A device for styling hair includes a wand defining a handle grip surface and a first styling surface spaced from the handle grip surface and a plate defining a second styling surface, the plate being pivotally coupled to the wand to clamp the hair between the first styling surface and the second styling surface. The device further includes a heating element in thermal communication with the first styling surface or the second styling surface to transfer heat to the hair via the first styling surface or the second styling surface, respectively, and an ultrasonic transducer configured to generate ultrasonic vibrations. The ultrasonic transducer includes a horn in contact with the wand or the plate to transmit the ultrasonic vibrations to the hair via the first styling surface or the second styling surface, respectively. | 05-12-2011 |
20110203606 | ADJUSTABLE-BARREL CURLING IRON - A radially adjustable barrel, a barrel-adjustment assembly, a radially adjustable heater assembly, and a radially adjustable distal-tip assembly. The barrel is radially adjustable between expanded and contracted positions having different diameters. The barrel-adjustment assembly includes a rotary ring defining a spiral cam guide and includes a cam follower attached to the barrel. The heater assembly includes a post, at least one heater, and at least one spring mounting the heater to the post and biasing the heater radially outward. In use, rotating the ring rotates the spiral cam guide, which displaces the cam follower radially inward or outward, which in turn displaces the outer end of the barrel radially inward or outward to decrease or increase the diameter of the barrel. As the diameter of the barrel is adjusted, the heaters remain in contact with the barrel due to the outwardly biasing influence of the spring. | 08-25-2011 |
20110209721 | Ultrasonic Hair Dryer - A device for drying hair includes a housing having an air inlet and an air outlet spaced from the air inlet to define an airflow path through the housing. The device also includes a fan disposed within the housing along the airflow path, a hairstyling implement disposed at the air outlet, and an ultrasonic transducer configured to generate ultrasonic vibrations. The transducer is coupled to the hairstyling implement to transmit the ultrasonic vibrations to the hair. | 09-01-2011 |
