20140303453 | System and Method for Generating Composite Measures of Variability - A system and method are provided for assessing the degree of critical illness of patients in Intensive Care Units (ICUs), and the detection of occurrence of specific clinical outcomes, pursued through the monitoring of a variety of physiological signals, extraction of multiple measures of variability, and integration of the relevant information the measures of variability bring. The integration process leads to the creation of a compound variable, referred to as a composite measure of variability, which can be tuned to various clinical needs, since the process of normalization, feature selection and data integration are customizable to the clinical indication, planned use of the composite variability monitoring. The system and method also enable joining the composite measure of variability with clinical factors, so as to estimate the likelihood of developing specific clinical outcomes. | 10-09-2014 |

20120187049 | Method of Removing Multi-Valent Metals From Crude Oil - Multi-valent metals, such as iron, may be removed from crude oil by introducing at least one metal removal chemical to the crude oil before, during or after the crude oil is charged to a settling tank. After mixing the metal removal chemical with the crude oil, the crude oil is kept still or held quiescent for an effective period of time to allow the metal species to settle to the bottom of the tank. Oil having reduced metal content may be removed from the top of the tank and/or metal-rich oil may be drained from the bottom of the tank or both. The crude oil having reduced metal content will cause fewer problems downstream in the refinery. | 07-26-2012 |
