  • Publication number: 20260051810
    Abstract: A system includes four primary-side switches of a primary bridge of a dual active bridge (DAB) converter, four secondary-side switches of a secondary bridge of the DAB converter, and control circuitry configured to operate the DAB converter in a first mode, where all of the four secondary-side switches operate under zero voltage switching (ZVS) and less than all of the four primary-side switches operate under ZVS, and, in response to a thermal condition, operate the DAB converter in a second mode, where less than all of the four secondary-side switches operate under ZVS and all of the four primary-side switches operate under ZVS. A method includes operating the control circuitry of the system to implement the first and second modes. In some embodiments, the control circuitry toggles between the first and second modes based on one or more thermal conditions.

  • Publication number: 20250266747
    Abstract: Current sensor compensation is provided. A system can include a charger for an electric vehicle having one or more controllers. A controller can amplify an input signal at a selected frequency to generate a first signal. A controller can amplify a direct current component of the input signal to generate a second signal. A component of the charger can generate a reference signal for input into a current sensor of the charger. The reference signal can be based on a combination of the first signal and the second signal.

  • Patent number: 12291578
    Abstract: A method of treating a disease associated with imbalanced or abnormal activity of MMP-7 is diclosed. The method comprises administration of an antibody comprising an antigen recognition region which binds a catalytic site of MMP-7, having complementarity determining region amino acid sequences as set forth in: SEQ ID NOs: 3, 4 and 5 (CDR3), sequentially arranged from N to C on a light chain of the antibody; and SEQ ID NOs: 6, 7 and 8, sequentially arranged from N to C on a heavy chain of the antibody.

  • Publication number: 20240178679
    Abstract: Controlling reverse in-rush current for vehicle chargers is provided. A system can include a controller to determine a first value of voltage. The voltage can be of or associated with a DC link of a charger to output power to a battery of an electric vehicle. The controller can detect an in-rush current from the battery to the charger. The detection can be responsive to the first value of voltage at the DC link being greater than a reference value of voltage established for the DC link.

  • Patent number: 11870352
    Abstract: Systems and methods for controlling a dual active bridge converter are disclosed herein. An output voltage of a dual active bridge converter is sensed. Based at least in part on the output voltage, a target intra-bridge phase shift amount between two bridges of the dual active bridge converter is computed. A plurality of switch control signals, which are provided to respective switches of the dual active bridge converter, are caused to switch according to a time-based switching sequence based on the target intra-bridge phase shift amount to compensate for variations in the output voltage.

  • Patent number: 11841109
    Abstract: A method using a specially configured computer display support structure reduces occurrences of medical errors by facilitating real-time, synchronous review of medical data by rounding professionals during patient rounds. The support structure includes an upright column assembly that has a column assembly base and six sides. Mounting brackets fixed to non-contiguous sides of the column assembly receive back plates of a system device mounting assembly, each of which includes a pivot arm that receives a system device arm. The system device arm is pivotable at opposing ends and terminates in a coupling member at its distal end. The coupling member is connected to a video display that has an angularly positionable display screen. In some embodiments, a keyboard tray, on which a keyboard and computer mouse rest, is connected to the coupling member.
