Patent number: 7048204Abstract: An irrigation controller (200) receives temperature data, and at least partly derives an estimated solar radiation value from the temperature data. A regression model stored in a memory (220) of the irrigation controller (200) operates upon a data point from the estimated solar radiation to estimate an evapotranspiration rate, which is used to affect an irrigation schedule executed by the controller (200). The regression model is preferably based upon a comparison of historical ETo values against corresponding historical environmental values, with the data advantageously spanning a time period of at least two days, and more preferably at least one month. Data from one or more environmental factors may also be used, including especially estimated solar radiation, temperature, wind speed, humidity, and soil moisture, and so forth. Values relating the environmental factor(s) may enter the controller from a local sensor (240), a distal signal source, or both.Type: GrantFiled: November 6, 2000Date of Patent: May 23, 2006Assignee: Aqua Conserve, Inc.Inventors: John W.

Patent number: 7048209Abstract: An apparatus and method of compensating for thermal expansion and tolerance variations (wear, brinelling, mounting distortion) in a fuel injector is provided. The apparatus includes a magneto-hydraulic thermal expansion compensator containing magnetically-active fluid positioned in operative contact with the fuel injector actuation element. A electromagnetic coil is provided proximate the magneto-hydraulic compensator. Magnetic flux generated by the electromagnetic coil causes the viscosity of the magnetically-active fluid within the magneto-hydraulic compensator to increase, causing the magneto-hydraulic compensator to become substantially rigid during actuation of the fuel injector.Type: GrantFiled: August 22, 2003Date of Patent: May 23, 2006Assignee: Siemens VDO Automotive CorporationInventor: Perry Robert Czimmek
