摘要:
A superconducting energy storage inductor having two D-shaped coils with their flat sides being adjacent and facing one another. The coils are restrained from moving relative to one another and are immersed in a cryogenic fluid. The coils are connected in series and when provided with current, the resulting magnetic fields of the coils oppose one another.

Knee flexion devices and method for using the knee flexion devices are provided. The knee flexion devices include a base member having an elongate body and a tower member extending outward from the base member at a selected predetermined angle. The knee flexion devices further include a foot plate engaging the base member and configured to be movable along the elongate body of the base member.
摘要:
A low-voltage, low-inductance device for storing electrical charge in a snubber circuit and a method of minimizing inductance in the snubber circuit using the device, wherein the device includes a plurality of extended electrodes, in parallel or series, that are joined to a positive conductor terminal at one end spray and at a negative conductor terminal at the other end spray so that end sprays of adjacent extended electrodes are alternately joined to the positive and negative conductor terminals. Accordingly, current flowing though adjacent extended electrodes is of substantially equal intensity but different in direction. As a result, inductance produced effectively cancels out that of adjacent extended electrodes.
