  • Four-braid resistive heater and devices incorporating such resistive heater
    Patent number: 10080258
    Abstract: An apparatus includes a four-braid resistive heater, which includes a conductive structure configured to transport electrical currents and to generate heat based on the electrical currents. The conductive structure has first, second, third, and fourth electrical conductors. The first and second electrical conductors are looped around each other along a length of the conductive structure. The third and fourth electrical conductors are looped around each other along the length of the conductive structure. Loops formed with the first and second conductors are interleaved with loops formed with the third and fourth conductors along the length of the conductive structure. The first and third electrical conductors can be electrically coupled together, and the second and fourth electrical conductors can be electrically coupled together.
