  • Publication number: 20240351092
    Abstract: An apparatus for straightening wire in a directed energy deposition additive manufacturing machine. The apparatus includes at least three roller bearings positioned along one side of a longitudinal axis and a first adjustable bearing and a second adjustable bearing positioned along another side of the longitudinal axis. The first adjustable bearing and the second adjustable bearing are connected to a body and are positioned in a staggered alternating pattern with the at least three roller bearings. Further. the first adjustable bearing and the second adjustable bearing are each configured to apply a load to the wire. A directed energy deposition additive manufacturing machine includes the apparatus. A method for straightening a wire including feeding the wire into the apparatus.

  • Patent number: 11070065
    Abstract: A modular management system for balancing, testing and protecting rechargeable energy storage cells connected in series. Different energy storage cell technologies can be connected in the same battery pack and they can be completely balanced by using one or both of two balancing modes. In addition, the modular management system includes bidirectional and unidirectional switches optionally connected to a single ohmic device such as a resistor to efficiently execute a Dual Function Process (DFP) (i.e., passive/active balancing, and testing mode for SoH/SoC estimation) preferably without using any extra or external components (i.e., capacitor or inductor or DC/DC converter or power supply). The systems and methods decrease the balancing time, energy loss, heat loss and complexity needed to monitor, protect and balance energy storage cell systems such as battery systems, and thus decreasing the overall cost.
