  • Patent number: 10674374
    Abstract: Apparatus, systems and articles of manufacture to provide improved, dynamic wireless spectrum analysis in a healthcare environment are disclosed and described. An example apparatus includes radios to capture wireless signal information in an environment. The example apparatus includes a processor to activate and configure one or more of the radios according to a center frequency and/or a bandwidth to capture wireless signal information associated with the center frequency and/or bandwidth. The example processor is to generate a model of wireless signal activity based on the captured wireless signal information. The example model is to facilitate testing of a device according to the wireless signal activity in the environment. The example apparatus is to be portable to be positioned in the environment to capture the wireless signal information in the environment according to the one or more radios activated and configured by the processor for the environment.

  • Patent number: 8686725
    Abstract: An apparatus includes a first magnetic resonance (MR) coil element configured to output a first set of MR data at a first output frequency and a first mixer coupled to the first MR coil element. The first mixer is configured to receive the first set of MR data from the first MR coil element and frequency translate the first set of MR data to a first offset frequency different from the first output frequency by a first offset value. The apparatus also includes a digitizer coupled to the first mixer and configured to convert the frequency-translated first set of MR data into a set of digital data and a transmission line coupled to the first mixer and to the digitizer, the transmission line configured to transmit the frequency-translated first set of MR data from the MR coil element to the digitizer without a balun coupled to the transmission line.
