Patent number: 8313306Abstract: Embodiments of the invention provide a method of operating a safety vacuum release system (SVRS) with a controller for a pump including a motor. The method can include measuring an actual power consumption of the motor necessary to pump water and overcome losses. The method can include triggering the SVRS when a dynamic suction blockage is identified in order to shut down the pump substantially immediately. The SVRS can also be triggered when a dead head condition is identified based on the actual power consumption.Type: GrantFiled: October 2, 2009Date of Patent: November 20, 2012Assignees: Pentair Water Pool and Spa, Inc., Danfoss Low Power DrivesInventors: Robert W.

Publication number: 20120110413Abstract: The invention relates to a method for encoding digital data, in particular of data processed in a microprocessor unit. In the method according to the invention for a respective data word (A, B, C) of a series of data words to be encoded subsequently a parity code (P(A), P(B), P(C)) is computed on the basis of the data of the respective data word (A, B, C). Further the respective data word (A, B, C) is altered with the aid of the data word (A, B, C) preceding it in the series, wherein the altered data word (Aa, Ba, Ca) and the parity code (P(A), P(B), P(C)) represent the encoded data word (Ac, Bc, Cc) and the encoded data word (Ac, Bc, Cc) can be decoded with the aid of the data word (A, B, C) preceding it in the series.Type: ApplicationFiled: June 22, 2010Publication date: May 3, 2012Inventor: Lars Hoffmann

Publication number: 20120020810Abstract: Embodiments of the invention provide a pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, and a controller in communication with the motor. The controller determines an actual power consumption of the motor and compares the actual power consumption to a reference power consumption. The controller also determines that the pump is in an unprimed condition if the actual power consumption is less than the reference power consumption and that the pump is in a primed condition if the actual power consumption is at least equal to the reference power consumption.Type: ApplicationFiled: August 29, 2011Publication date: January 26, 2012Inventors: Robert W.

Patent number: 8019479Abstract: 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.Type: GrantFiled: November 23, 2005Date of Patent: September 13, 2011Assignee: Pentair Water Pool and Spa, Inc.Inventors: Robert W.
