  • Patent number: 10389248
    Abstract: The present embodiments are directed to circuitry and techniques for operating a switching regulator, including in connection with transitions out of energy conservation modes during which a minimal amount of current is drawn from a power source such as a battery. According to certain aspects, embodiments of an energy conservation mode include provisions for maintaining high performance voltage regulation even in the face of a sudden increase in load requirements. These and other embodiments can further include various techniques for signaling an appropriate transition for exiting out of energy conservation mode and into a continuous conduction mode.

  • Publication number: 20100085024
    Abstract: An embodiment of a power-supply controller includes a control circuit and a detection circuit. The control circuit has a signal characteristic, and is operable in response to a regulated output signal and a reference signal to cause at least one power-supply phase to generate the regulated output signal. The detection circuit is operable to detect a change in the regulated output signal, and to alter the signal characteristic of the control circuit in response to the detected change.

  • Patent number: 5554218
    Abstract: This invention relates generally to the field of cement, especially cement for underwater application. The invention provides a composition for preparing cement that solidifies underwater comprising exothermic micro particles and base cement. Exothermic micro particles are less than about two thousand two hundred and fifty micrometers in diameter and can be, for example, calcium chloride. The invention further provides a kit for preparing cement that solidifies underwater comprising exothermic micro particles in a container and base cement. The invention provides a method of underwater construction or repair comprising mixing a composition comprising exothermic micro particles and base cement with water and applying the composition to an underwater structure where the composition solidifies. The composition, kit and method are particularly well suited for swimming pool repair.
