摘要： The invention relates to a device (1) for magnetic resonance imaging of a body (7), comprising a main magnet (2) for generation of a stationary and substantially homogeneous main magnetic field within the examination zone, a plurality of wireless receiving units (10a, 10b) placed in or near the examination zone, and sampling means (21a, 21b) operating at a variable sampling frequency for sampling the received MR signals and for converting them into digital signal samples. In order to provide an MR device (1), which is arranged to inductively energize the wireless receiving units (10a, 10b) without interference with the nuclear spin system of the examined object (7) and which does not necessarily require bulky energy storage means for the operation of the wireless receiving units (10a, 10b), the invention proposes to make provision for energizing means (17) generating an RF energizing field within the examination zone for inductively supplying electric power to the wireless receiving units (10a, 10b), wherein the frequency of the RF energizing field is an integer multiple of the sampling frequency.

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.
