摘要： An antenna system for an implantable device like a cardiac pacemaker or a cochlear implant. The antenna system includes at least two coil units coupled with their terminals to a control circuit which can selectively connect the coil units in series or in anti-series, corresponding to a “operational mode” and a “safety mode”, respectively. In the operational mode, magnetically induced voltages in the coil units add, while they subtract and therefore completely or partially compensate in the safety mode. Thus the implantable device can be protected from damage due to extraordinarily large changing rates of external magnetic fields as they exist for example during MRI examinations.

摘要： The invention relates to an antenna system (AS) for an implantable device like a cardiac pacemaker or a cochlear implant. The antenna system comprises at least two DD coil units (L1, L2) coupled with their terminals (T1 1, T21, T 12, T22) to a control circuit (CC) which can selectively connect the coil units in series or in anti-series, corresponding to an “operational mode” and a “safety mode”, respectively. In the operational mode, magnetically induced voltages (U1, U2) in the coil units add, while they subtract and therefore completely or partially compensate in the safety mode. Thus the implantable device can be protected from damage due to extraordinarily large changing rates of external magnetic fields as they exist for example during MRI examinations.

摘要： The invention relates to an electrical power distribution apparatus (100) connectible to one or more loads (119). The electrical power distribution apparatus (100) comprises inter alia one or more taps (112) for supplying the loads (119) with electrical power. On top of circuit breakers (108) to switch off the power supply in order to protect the loads against damage, there is also arranged a second layer of soft fuse switches (110) which are arranged to switch on or off the power supply at the taps (112) to control distribution of the power. The soft fuses (110) operate in dependence on and in response to commands issued from a controller (105) which in turn operates and issues those commands in response to and independence on the voltages and amperages monitored at those taps (112) by way of a monitoring module (111). Switching on/off occurs at amperage and voltages lower than the critical threshold values to which the circuit breakers (108) respond to.
