  • Patent number: 11231450
    Abstract: A device for measuring an electric field includes a micromechanical structure made of a material that is electrically conductive at an operating temperature. The micromechanical structure has a frame portion and a movable portion; the movable portion is electrically conductively and mechanically elastically connected to the frame portion and can be moved relative to the frame portion; the micromechanical structure is designed so that, when the micromechanical structure is arranged in the electric field, an electrical polarization of the micromechanical structure occurs by a first field intensity component not equal to zero and is parallel to a first direction, the electrical polarization causing a first force component acting on the movable portion parallel to the first direction and a change in the spatial arrangement of the movable portion relative to the frame portion dependent on the first force component. A detector determines the change.

  • Patent number: 11226386
    Abstract: In a method for improved recording of scan data of an examination object by means of a magnetic resonance system with the aid of a simultaneous multi-slice (SMS) method, a minimum repetition time TR is determined dependent upon a quality criterion. The quality criterion herein extends the scan time, which is actually greatly shortened by the use of an SMS method, for the MR signals of the slice stack to be recorded, to the minimum repetition time TR. The “time reserve” thereby obtained (the difference of the determined minimum repetition time TR from the scan time needed for the slice stack to be recorded purely by means of the SMS method) is utilized to take account of further slices in the recording of the MR signals. By this means, firstly, further information can be obtained and, secondly, the image quality of the image data obtained is improved.

  • Patent number: 11221384
    Abstract: The present disclosure provides a method for producing a radio frequency (RF) pulse for use in magnetic resonance. The steps of the method include providing a computer system and a set of RF input parameters. The computer system then generates an optimal phase surface by iteratively updating an initial RF pulse profile based at least in part on the set of RF input parameters. The optimal phase surface contains a set of iteratively generated RF pulse profiles with various characteristics, such as bandwidths or selectivity. The steps of the method further include selecting an RF pulse profile with the computer system based on a search on the optimal phase surface, which can be implemented with the help of an index file. The search can be performed using an artificial intelligence algorithm, and can retrieve the shortest pulse profile that satisfies user input parameters or requirements.

  • Patent number: 11215668
    Abstract: Apparatus and associated methods relate to a system or method of precision battery charge measurement. Some embodiments may include precise charge and discharge control based on precision battery voltage and current sensing. In an illustrative example, energy either going in or out of the battery may be multiplied or computed using novel circuitry. In various embodiments, energy may be computed in a precision energy small unit determined as a percentage of total battery capacity. In an illustrative example, the precision unit may be, for example, 0.0018% of the total battery capacity. In some embodiments, the energy meter value may be in digital form, so it can be stored in memory and transmitted to external users as desired using USB type C or any other method. Various embodiments may advantageously provide extended battery life, based on using the measured energy meter value to maintain the state of charge of the battery.
