| 20100185423 | METHOD FOR DESCRIBING RELATIONS IN SYSTEMS ON THE BASIS OF AN ALGEBRAIC MODEL - A method for describing one or more relations in a physical or other system on me oasis of an algebraic model of the system comprises the steps of: a) collecting data comprising measurements of different quantities relating to the system; b) interpreting the measurements of the different quantities as evaluations of different variables, which together comprise a polynomial ring; c) calculating an ideal of the ring, the generators of which substantially vanish on the collected data; d) interpreting the generators as polynomial relations between the variables of the system; e) reformulating at least one of the polynomial relations as an algebraic model for one of the variables in terms of the other variables involved in this relation; and f) the algebraic model is induced to generate one or more governing relations between parameters that govern the system using only measured data of the system. The algebraic model used in the method according to the invention is also identified as the Approximate Buchberger-Moeller algorithm, which computes a substantially or approximately vanishing ideal of a finite set of points and which remains numerically stable if the points are imprecise measured data. | 07-22-2010 |

| 20080237944 | Method For Operating a Shaft Furnace, and Shaft Furnance Operable By That Method - Method for operating a shaft furnace, whereby an upper section of the shaft furnace is charged with raw materials which due to gravity descend inside the furnace while the atmosphere prevailing within the shaft furnace causes part of the raw materials to melt and/or to be reduced, and in a lower section of the shaft furnace a process gas is injected so as to at least partly modify the atmosphere prevailing in the shaft furnace. The pressure and/or volume flow of the injected process gas is dynamically modulated within a time span of 40 s. Also, a shaft furnace operable by said method, thus achieving improved through-gassing. | 10-02-2008 |

| 20090304940 | COMPACT PAINT BOOTH AND METHOD - Paint booths for applying paint to an object, as well as methods for degrading coating operations associated with a paint booth, are disclosed. Paint booth may generally include one or more robot rails positioned parallel to the path of the conveyor, and one or more robots positioned on at least one of the rails. Robots may be configured to simultaneously apply a first paint layer to the interior and exterior surfaces of the object. Paint booths may further include one or more additional robots positioned on at least one of the rails and configured to simultaneously apply a second paint layer to the interior and exterior surfaces of the object. | 12-10-2009 |

| 20120037716 | PAINT DELIVERY AND APPLICATION APPARATUS AND METHOD - A paint delivery and application apparatus, wherein the apparatus includes a source of paint, a paint applicator, a supply line interconnecting the source of paint and the applicator and at least one pig in the supply line, wherein the paint pushes the pig from adjacent the source of paint to the paint applicator and a source of purging solvent delivering a small volume of purging solvent to the supply line when the pig is adjacent the source of paint adjacent to and upstream of the pig acting as a lubricant, reducing chattering and skipping of the pig and extending the life of the pig. Where the apparatus includes two pigs, purging solvent is delivered between the pigs adjacent the applicator, the pigs are delivered to adjacent the source of paint and a small volume of solvent is then delivered from between the pigs upstream of the pigs. | 02-16-2012 |

| 20090305746 | Device for Coupling and Housing a Mobile Telephone in a Motor Vehicle - A system for accommodating a mobile telephone in a compartment in a motor vehicle. The compartment is electromagnetically shielded against the emission of radio signals from the mobile telephone. The system includes a connector for transmitting an antenna signal from an antenna of the motor vehicle to the mobile telephone, an electromagnetically shielded housing with an opening for inserting the mobile telephone into the housing and for removing the mobile telephone from the housing, and an elastically deformable retaining element that is designed to be electromagnetically absorbing. In a closed state of the housing in which the opening of the housing is at least partially closed, the opening at least partially shields against the emission of radio signals of the mobile telephone from the housing. In the closed state the retaining element secures the mobile telephone in a temporary position. | 12-10-2009 |

| 20080287753 | SYSTEM AND METHOD FOR PREDICTION AND DETECTION OF CIRCULATORY SHOCK - Systems and methods for prediction and detection of circulatory shock using estimates or measurements of arterial blood pressure, heart rate, stroke volume, cardiac output, total peripheral resistance, cardiac ejection fraction, cardiac contractility and ventricular end-diastolic volume are provided. These estimates and measurements are used to determine a type of circulatory shock. In some embodiments, the type of circulatory shock is determined to be one of septic shock, hypovolemic shock, anaphylactic shock, hemorrhagic shock, and cardiogenic shock. | 11-20-2008 |
| 20080287812 | Systems and Methods for Model-Based Estimation of Cardiac Output and Total Peripheral Resistance - The methods and systems for estimating cardiac output and total peripheral resistance include observing arterial blood pressure waveforms to determine intra-beat and inter-beat variability in arterial blood pressure and estimating from the variability a time constant for a lumped parameter beat-to-beat averaged Windkessel model of the arterial tree. Uncalibrated cardiac output and uncalibrated total peripheral resistance may then be calculated from the time constant. Calibrated cardiac output and calibrated total peripheral resistance may be computed using calibration data, assuming an arterial compliance that is either constant or dependent on mean arterial blood pressure. The parameters of the arterial compliance may be estimated in a least-squares manner. | 11-20-2008 |
| 20080294057 | SYSTEMS AND METHODS FOR MODEL-BASED ESTIMATION OF CARDIAC EJECTION FRACTION, CARDIAC CONTRACTILITY, AND VENTRICULAR END-DIASTOLIC VOLUME - The methods and systems for estimating cardiac ejection fraction, cardiac contractility, and ventricular end-diastolic volume on a beat-by-beat basis include observing arterial blood pressure waveforms to determine ventricular compliances for a pressure-volume loop in the ventricle. Uncalibrated or calibrated cardiac ejection fraction may be calculated from estimates of stroke volume and the ventricular compliances. Cardiac contractility may be calculated from estimates of a ventricular compliance. Uncalibrated or calibrated ventricular end-diastolic volume may also be calculated from estimates of stroke volume and the ventricular compliances. A set of calibration parameters for calibrating cardiac ejection fraction or ventricular end-diastolic volume may be estimated in a least-squares manner. | 11-27-2008 |
| 20100063405 | SYSTEMS, DEVICES AND METHODS FOR NONINVASIVE OR MINIMALLY-INVASIVE ESTIMATION OF INTRACRANIAL PRESSURE AND CEREBROVASCULAR AUTOREGULATION - The systems, devices, and methods described herein provide for the estimation and monitoring of cerebrovascular system properties and intracranial pressure (ICP) from one or more measurements or measured signals. These measured signals may include central or peripheral arterial blood pressure (ABP), and cerebral blood flow (CBF) or cerebral blood flow velocity (CBFV). The measured signals may be acquired noninvasively or minimally-invasively. The measured signals may be used to estimate parameters and variables of a computational model that is representative of the physiological relationships among the cerebral flows and pressures. The computational model may include at least one resistive element, at least one compliance element, and a representation of ICP. | 03-11-2010 |
