20130297928 | Field device with long-term firmware compatability - A field device having at least one memory and at least two replaceable modules, each of which has hardware and firmware associated with the hardware. In such case, firmware version information of a compatible firmware version combination of the modules of the field device is stored in the at least one memory or such is storable therein at a first-time start-up of the field device. Furthermore, the field device is embodied in such a manner that a comparison in the case of at least one module of its firmware version with the firmware version information stored in the memory is automatically performable and that the module is automatically switchable to the firmware version as claimed in the firmware version information, in case the comparison shows a deviation of the firmware version of the module from the firmware version of the firmware version information stored for the corresponding module. | 11-07-2013 |

20110046488 | AUTOMATED MONITORING OF MYOCARDIAL FUNCTION BY ULTRASONIC TRANSDUCERS POSITIONED ON THE HEART - The invention relates to a method and a post-operative care unit for analysing and quantifying an ultrasound tissue Doppler imaging (TDI) signal from a transducer fastened on the myocardium to obtain a parameter indicating regional cardiac ischaemia or correlates with global hypokinetic heart function. This has the advantage over manually operated probes that it can be automated and used continuously over long time. According to the method, a TDI signal trace corresponding to at least one of tissue velocity, strain or strain rate is extracted and correlated with an electrocardiogram to define subsections within a cardiac cycle in the extracted trace corresponding to the early systolic phase and the post-systolic phase. Then, a velocity, strain or strain rate is read in at least the post-systolic phase of the extracted trace, and a parameter which is a function of one of these readings and which indicates ischaemia or global hypokinetic function is generated. | 02-24-2011 |

20080281214 | Method for estimating cardiac pumping capacity - The present invention provides a system and a method for estimating changes in cardiac pumping capacity in response to an intervention from data recorded by an accelerometer positioned on an outer surface of the heart. Interventions such as intravenous administration of nitroprusside, betablocker, epinephrine (adrenaline), or changes in the intravascular volume such as by fluid filling, are considered. It is shown that it is possible to directly correlate changes in cardiac pumping capacity to changes in parameters or graphical representation derived from signals characteristic to the acceleration an outer surface of the heart. In particular, it is shown how the effect of the interventions can be directly read from these parameters or graphical representations, and can thereby assist in decisions regarding the treatment of a cardiac surgery patient. The invention is preferably used in a post-surgery monitoring unit for surveillance of cardiac surgery patients. | 11-13-2008 |
