Publication number: 20100096338Abstract: The invention discloses a management arrangement for a swimming pool. The arrangement includes a number of sensors being adapted to measure variables and generate input data relating to a swimming pool. The input data is processed by a processing unit to generate output data, which data is then used by an actuator to control equipment. Various operating parameters are programmable into the processing unit via an operator interface. The arrangement provides a combination of ultraviolet treatment and ion enrichment in order to disinfect or purify the water. The arrangement specifically regulates the ionization of the swimming pool water so as to substantially maintain a pre-determined ion concentration level with reduced operator intervention.Type: ApplicationFiled: September 23, 2009Publication date: April 22, 2010Inventors: Riccardo Arthur De Wet, Daniel Alfonso Corte, Uwe Thuss

Publication number: 20100038317Abstract: A multipurpose hemofiltration system and method are disclosed for the removal of fluid and/or soluble waste from the blood of a patient. The system continuously monitors the flow rates of drained fluid, blood, and infusate. When necessary, the pumping rates of the infusate, drained fluid and blood are adjusted to remove a preselected amount of fluid from the blood in a preselected time period. A supervisory controller can monitor patient parameters, such as heart rate and blood pressure, and adjust the pumping rates accordingly. The supervisory controller uses fuzzy logic to make expert decisions, based upon a set of supervisory rules, to control each pumping rate to achieve a desired flow rate and to respond to fault conditions. An adaptive controller corrects temporal variations in the flow rate based upon an adaptive law and a control law.Type: ApplicationFiled: October 19, 2009Publication date: February 18, 2010Applicant: CHILDREN'S HOSPITAL MEDICAL CENTERInventors: John J.
