  • Publication number: 20180069394
    Abstract: A power-limit protection circuit with an efuse element. The power-limit protection circuit has an efuse element coupled between a first terminal and a second terminal. The power-limit protection circuit judges whether a calculated power signal defined from a current signal flowing through the efuse element and a voltage signal at a terminal of the efuse element is larger than a predetermined power threshold. When the calculated power signal is larger than the predetermined power threshold, the power-limit protection circuit increases an impedance of the efuse element to limit the current signal between the first terminal and the second terminal such that the power delivered through the efuse element is limited within the predetermined power threshold.

  • Publication number: 20050003207
    Abstract: A water-vapor-permeable, watertight, heat-reflecting flat composite is made by a process of combining a metal layer and a nonporous, water-vapor-permeable, watertight, hydrophilic flat substrate. The process includes at least the three steps of (1) selecting the substrate, (2) pre-cleaning the substrate, and (3) applying the substrate to the metal layer. Such a composite offers protection from heat loss, infrared-based detection, ultraviolet radiation, electro-smog, and static electricity.

  • Patent number: 4075934
    Abstract: A piston for internal combustion engines, preferably made from aluminum alloy, has machined, oil-dragging grooves formed on the periphery of the piston skirt and concave transitions with a sawtoothlike profile with an obtuse profile angle. The piston skirt is provided with an electrodeposited hard iron layer having a thickness of 1-30 .mu.m and contains 0.5-6% metal-oxy compounds incorporated therein.
