  • Publication number: 20180138717
    Abstract: One or more techniques and/or systems are provided for transferring power and/or information between a stator and a rotor. The rotor includes a high voltage rectifier filter and an auxiliary regulator coupled to a power transfer apparatus (e.g., rotary transformer). The high voltage rectifier filter is configured to receive a first electrical signal, associated with a first voltage, from the power transfer apparatus and to generate a second electrical signal, associated with a second voltage, based on a frequency and/or an amplitude of the first electrical signal. The auxiliary regulator is configured to generate a third electrical signal based on the first electrical signal, where a third voltage associated with the third electrical signal is generated independent of the frequency and/or amplitude of the first electrical signal. A single bi-directional data link is used for control and/or communication between the stator and the rotor.

  • Patent number: 9431921
    Abstract: One or more systems and/or techniques are provided for electrically coupling and/or decoupling a capacitive snubber component to/from an inverter as a function of a current in the inverter. A current sensing component may be configured to measure the current in the inverter and/or determine whether the current in the inverter exceeds a desired threshold. The desired threshold may be set at a value sufficient to reset the capacitive snubber component. When the current in the inverter is above the desired threshold, the capacitive snubber component may be coupled to the inverter. When the current in the inverter is below the desired threshold, the capacitive snubber component may be decoupled from the inverter. In this way, little to no energy stored in the capacitive snubber component may be dissipated in the inverter when the current in the inverter drops below a level sufficient to reset the capacitive snubber component.

  • Patent number: 9241393
    Abstract: Among other things, one or more techniques and/or systems for selectively inhibiting radiation from being generated by a radiation source are provided. A radiation source comprises an electrically conductive gate situated between a cathode and an anode. When a voltage potential is created between the gate and the cathode, a flow of electrons between the cathode and the anode is mitigated, thus inhibiting radiation from being generated by the radiation source. When the voltage potential is removed or lessened, electrons may more freely flow between the cathode and the anode to generate radiation. In some embodiments, a calibration, such as a dark calibration, may be performed while the gate mitigates the flow of electrons. Moreover, in some embodiments, an accelerating voltage applied to the radiation source may be held substantially constant when radiation is generated as well as when radiation generation is inhibited.

  • Patent number: 9008275
    Abstract: Among other things, one or more techniques and/or systems are provided for varying a voltage applied to a radiation source of an imaging modality to vary an energy of emitted radiation. A power supply comprises at least two rectifiers, with a first rectifier being electrically separated from a second rectifier via a switching component. When the switching component is opened, the first and second rectifiers are effectively arranged in parallel, and when the switching component is closed, the first and second rectifiers are effectively arranged in series. The voltage applied by the power supply may be different based upon whether the rectifiers are arranged in parallel or in series, but the power output by the power supply may remain substantially constant regardless of the rectifier arrangement.
