  • Patent number: 10345388
    Abstract: A method for screening a lithium ion battery is provided. A number of lithium ion batteries are galvanostatically discharged a to an inflection point voltage at an inflection point of a discharge curve at a first constant current I1. The number of lithium ion batteries are rested for a first rest time T1 to raise an open circuit voltage of the number of lithium ion batteries to U1. U1 is greater than the inflection point voltage. The number of lithium ion batteries are galvanostatically discharged to the inflection point voltage at a second constant current I2, in which I2<<I1. The number of lithium ion batteries are rested for a second rest time T2 and the batteries are screened based on a self-discharge of the number of lithium ion batteries.

  • Patent number: 6321417
    Abstract: The present invention provides an ergonomical handle for a power tool that reduces the risk of injury to an operator's wrist or forearm by redirecting torsional forces to the operator's upper arm and reducing the force provided by the tool operator necessary to resist the torque produced by the tool. The handle includes a concave channel and a means for attaching the handle to a tool adjacent to the barrel of the tool, such as an annular collar with a substantially elliptical outer diameter. In a preferred embodiment, the channel includes an inner side wall and an outer side wall that are curved in a nonparallel fashion so as to mirror the planar and dorsal sides of a hand. In use, a tool operator inserts a hand into the channel. The side walls of the channel frictionally engage the operator's hand so that the operator may operate the tool without gripping the barrel thereof.

  • Patent number: 6237446
    Abstract: A wrench adapter assembly is provided that can adapt a conventional manual or power wrench to be used to grasp and rotate a smooth-surfaced cylindrical object. The wrench adapter assembly includes of a pivoting hook, a biasing means for the hook, a wrench adapter with a multisided flange for engaging the jaw of a wrench and a concave jaw. The pivoting hook is in circumferential alignment with the concave jaw so as to receive a smooth-surfaced cylindrical article. The flange shoulder has sides that match up with the sides of the jaw of the wrench. Once the wrench adapter assembly is secured within the wrench jaw, it may receive and hold a smooth-surfaced cylindrical article. The wrench adapter rotates with the jaw of the wrench. Thus, the wrench may be used in combination with the wrench adapter assembly to rotate smooth-surfaced cylindrical articles.
