    摘要: A method, system, and apparatus including a magnetic resonance (MR) coil system that includes an MR coil element, a high input Pre-amplifier having a high input impedance field-effect-transistor (FET) with an impedance of one of substantially equal to 500 ohms and greater than 500 ohms, and a conductive path. The conductive path has a first end coupled to the MR coil element and a second end coupled to the high input Pre-amplifier such that the MR coil element is coupled in series with the high input Pre-amplifier. Further, the conductive path is free of a matching network intervening between the MR coil element and the high input Pre-amplifier.

    摘要: In a network, a first network station (61) communicates with a second network station (65) using a first channel (45) from a plurality of channels. The first channel (45) has a central frequency (46). A third network station (62) communicates using a sub-channel (55) of the first channel (45). The sub-channel overlaps the first channel (45). The sub-channel (55) has a center frequency (56) that varies sufficiently from the center frequency (46) of the first channel (45) so that the first network station (61) and the second network station (65) do not lock onto packets transmitted from the third network station (62). The center frequency (56) of the sub-channel (55) is closer in frequency to the center frequency (46) of the first channel (45) than to a center frequency of any other channel in the plurality of channels.
