  • Patent number: 11926306
    Abstract: An electronically slip-controllable power braking system for a motor vehicle, in which a controllably drivable pressure generator supplies multiple brake circuits connected in parallel to one another with pressure medium under brake pressure. Each of the brake circuits are separable through existing first control valves from the pressure generator and include second control valves that are connected downstream from the first control valves to control the brake pressure in the wheel brakes, which are connected with the brake circuits. An electronic control unit in the brake circuits has three devices, the third device puts the first control valve of a brake circuit into a passage position if a leakage is established downstream from the second control valve in this brake circuit and if it is established that the pressure generated by the pressure generator has at least approximately reached or exceeded a pressure limit of the first control valve.

    Abstract: A mechanism for generating and providing one or more quality measures of a mapping function (for mapping electrical responses of an electrode to a predicted position of that electrode within an anatomical cavity) to a user, such as a clinician. Each quality measure predicts or indicates a quality of a mapping function with respect to a particular part of an anatomical cavity, for instance, indicating a predicted accuracy of the mapping function for predicting a position of an electrode located within a particular portion of the anatomical cavity. A user-perceptible output is provided that indicates the quality measure for the user.

  • Publication number: 20230397958
    Abstract: A mechanism for generating a mapping function for mapping measurements taken at an electrode within crossing electric fields to a position or positions within a multidimensional co-ordinate system. The values for coefficients of the mapping function are generated using a first machine-learning algorithm, which receives, as input, example measurements (or responses) of the electrode and provides, as output, values for the coefficients for the mapping function. There is proposed a method and processing system for carrying out this mechanism.

  • Patent number: 11224394
    Abstract: The invention relates to an apparatus configured to display an aortic valve image and an indicator when the aortic valve is in its open-state and/or when the valve is in its closed-state. The indicator is supposed to be in an overlay to the image of the aortic valve, such that a physician can see on the same display image the information needed to advance a guide wire or catheter through the aortic valve of a heart. This may prevent damaging ensures not to damage the aortic valve. The physician receives the relevant information, when the aortic valve is in its open-state and thus being in a state to be passed by the catheter. The information, whether the aortic valve is in its open-state or in its closed-state, corresponds to the systolic phase and the distal phase of the heart, respectively. The information, when the heart is in its systolic phase and when it is in the diastolic phase may be extracted from an ECG measurement.

  • Patent number: 11219425
    Abstract: The invention relates to off-center detector X-ray tomography reconstruction of an image of an object on the basis of projection data acquired during a rotation of an X-ray source and the off-center detector around the object in two rotational passes of less than 360°, wherein a focus point of the X-ray beam travels along largely overlapping arcs (401, 402) in the two rotational passes, the off-center detector being positioned asymmetrically with respect to a central of the X-ray beam and a direction of a detector offset being reversed between the passes. According to the invention, redundancy weighting of the projection data with respect to a redundant acquisition of projection values during each of the rotational passes is made using a redundancy weighting function determined on the basis of a union of the arcs (401, 402).
