  • Patent number: 10852332
    Abstract: Wide deployment of high voltage battery systems in traction, industrial and renewable energy installations is raising the concerns for human safety. Exposure to hazardous high voltages may occur due to deterioration of insulation materials or by accidental events. It is thus important to monitor for such faults and being able to provide timely warnings to affected persons. For this purpose it has become mandatory for electrified passenger vehicles (CFR 571.305) to maintain high isolation values which can be continuously monitored by electrical isolation monitoring devices. The task of monitoring isolation resistance within the electrically noisy car environment is not a trivial task and the solution to this problem has become quickly a field of research and innovation for all affected industries.

  • Patent number: 10830843
    Abstract: The present disclosure relates to a method for a magnetic resonance system to protect a patient from being damaged by irradiated radio frequency power. In the method, amount information about maximum energy is determined as a function of a damage model for a patient to be examined with the magnetic resonance system. The maximum energy indicates the maximum radio frequency energy that may be radiated into the patient during the examination of the patient. Furthermore, an amount of energy emitted by a radio frequency amplifier of the magnetic resonance system during the examination of the patient in the magnetic resonance system is determined, and the radio frequency amplifier is adjusted as a function of a comparison of the amount information with the amount of energy emitted by the radio frequency amplifier.

  • Patent number: 10788517
    Abstract: Magnetic sensors may be positioned around an opening for a wire to measure the current flowing through the wire. A non-symmetric positioning of the sensors around the target measurement zone can enable an expanded measurement zone compared to conventional current measurement devices. Further, some sensors may be paired such that a hypothetical line connecting the sensors is tangential to the target measurement zone. Other sensors may be paired such that a hypothetical line between the sensors crosses the target measurement zone. The different pairs of the sensors can enable a reduction in the impact of stray field interference on the measurement of the current flowing through the wire.
