  • Publication number: 20240159836
    Abstract: A method and a device for calibrating an SOC at tail end of charging or discharging of an energy storage system are provided. An SOC and a voltage of a battery unit are acquired in real time during charging or discharging of the battery unit. Whether the battery unit meets an SOC calibration condition is determined by comparing the SOC of the battery unit with a pre-calibrated calibration SOC at the tail end of charging/discharge and comparing the voltage of the battery unit with a calibration voltage, so that the SOC of the battery unit is timely calibrated if the SOC calibration condition is met.

  • Patent number: 11981596
    Abstract: A fiber draw furnace includes a heated section configured to contain and heat a glass source from which an optical fiber is drawn. A lower extended muffle having a first end and a second end. A gas screen is coupled to the second end of the lower extended muffle configured to allow a gas to flow into the lower extended muffle. A reclaim cylinder is coupled to the lower extended muffle including an outer housing defining a reclaim chamber. A plurality of reclaim ports are tangentially coupled to the outer housing and an inner housing is positioned within the outer housing.

  • Patent number: 9965843
    Abstract: Methods for characterizing two-dimensional concept drawings are disclosed. The concept drawings comprise cross-sections intersecting at cross-hairs. The method comprises: determining, for each cross-section: a plane on which the cross-section is located, the plane having a normal vector in a three-dimensional coordinate system; and, for each cross-hair on the cross-section, a tangent vector in the three-dimensional coordinate system which is tangent to the cross-section at the cross-hair. For each cross-hair comprising ith and jth intersecting cross-sections, one or more constraints are satisfied, the constraints comprising: the normal vector ni of the plane on which the ith cross-section is located is at least approximately orthogonal to the normal vector nj of the plane on which the jth cross-section is located; and the tangent vector tij to the ith cross-section at the cross-hair is at least approximately orthogonal to the tangent vector tji to the jth cross-section at the cross-hair.
