  • Patent number: 10320263
    Abstract: An actuator includes a first stator with four first poles and a second stator with four second poles aligned with the four first poles. A permanent magnet is attached to the first stator and the second stator. Four moving armatures are positioned at terminal ends of the four first poles and the four second poles. Coils are wrapped around the first stator and the second stator. A controller selectively applies current to the coils to migrate flux created by the permanent magnet through selective poles of the first stator and the second stator and thereby alter the size of air gaps associated with the four moving armatures.

  • Publication number: 20180316347
    Abstract: A switching circuit includes a bridge rectifier to receive voltage inputs and an optical isolator to receive a logic input signal and generate an output signal based on the logic input signal. The high speed switching circuit also includes a field effect transistor (FET) with a source connected to a negative output of the bridge rectifier, a drain connected to a positive output of the bridge rectifier through a load, and a gate driven by the output signal of the optical isolator. First and second resistors connect the voltage inputs to the gate of the FET through first and second diodes. The first and second resistors and the first and second diodes limit current flowing to the gate of the FET. A Zener diode connected to the gate of the FET limits voltage to the gate of the FET below a maximum voltage rating of the FET.
