  • Patent number: 11621576
    Abstract: Example implementations include a method of reducing current overshoot in a power regulator device, by detecting a change in an input current of an inductive charger device in response to a change in load on the inductive charger device, modifying an operating state of the inductive charger device in accordance with a first input current limit parameter based on a total input current limit parameter and a current division parameter, in response to the detecting the change in the input current, operating the inductive charger device in accordance with the first input current limit during a current limit period subsequent to the detecting the change in the input current, modifying the operating state of the inductive charger device in accordance with a second input current limit parameter based on the total input current limit parameter and the current division parameter, subsequent to the current limit period, and operating the inductive charger device in accordance with the second input current limit subseque

  • Patent number: 7749936
    Abstract: A supported amorphous alloy catalyst, which is supported on a macroporous carrier-expanded graphite. The catalyst contains a Ni—B amorphous alloy (5 to 50% by weight) and a transition inductive metal (0.1 to 10% by weight). The diameter of expanded graphite carrier particles is 80-800 ?m. Its BET specific surface area is 10-100 m2/g. The catalyst is prepared by metal inductive electroless powder plating method which is easy to apply to industrial production. Ni—B clusters of prepared catalyst are well dispersed on the support. The catalyst shows high catalytic activity and good mechanical property, and is safe to use with low manufacturing costs.
