Title: Correction of blood pressure measurements in invasive liquid-filled systems
Inventor: WELLNHOFER ERNST
IPC: A61B5/0215
Filed: 1998-11-20
Abstract: The invention relates to a method for the correction of measured value falsifications in invasive pressure measurements with a fluid-filled system, in which the measured pressure is passed via the fluid--filled system to an external pressure transducer, which converts the pressure signal into an electrical signal.  To provide a method and a device for invasive pressure measurement with fluid-filled systems which are improved with respect to the correction of measured value falsifications, are cost-effective and versatile in their use, the electrical signal is passed through an analog/digital converter and the digitized signal is fed to a signal analyzing and processing unit, which operates on the basis of a digital Fourier analysis.  Furthermore, a heartbeat-related or segmental analysis is carried out and the signal is combined with empirically determined correction data on the basis of the analysis. The correction data are emitted as Fourier coefficients and the signal corrected by the signal analyzing and processing unit is passed to an output and/or evaluating unit.

IPC: B41J2/447
Filed: 2000-03-10
Abstract: A laser imager comprises a modulator with an array of electrodes to control picture elements individually or by groups to produce images on a recording plane. The light intensity of each picture element or group of elements is determined by electrical potential applied between sets of controlling electrodes. These levels can be manually set or automatically exercised during a balancing routine through a feed-back loop using a photodetector to monitor and detect elements producing a light intensity higher than a set value. Control means assign to these elements a "correction voltage" to lower the density of elements they control. These correction values obtained after one or repeated balancing routines are stored in a memory and are used during the imaging cycle to produce images of substantially equal intensity on the recording medium. Different electrode arrangements to control the intensity of picture elements can be applied to different kinds of modulators and for different power levels of radiated energy.
