  • Publication number: 20100261045
    Abstract: Methods and apparatus supporting an electrical connection are disclosed. Systems previously equipped with wire interfaces, such as battery terminals, can be equipped with a connector assembly to significantly reduce a hazard of electrical shock to a user. The connector assembly includes a stress relief component that attenuates a force, applied to the stress relief component, to reduce its effect on the connector assembly. By attenuating the force, the connector assembly maintains a substantially fixed position relative to the battery pack component and mitigates a potential for disruption in electrical connectivity. Techniques disclosed herein benefit users of battery packs or other devices as well as manufacturers by increasing safety, reliability, and ergonomics.

  • Publication number: 20100260497
    Abstract: Provided is a method of reducing power consumption of an optical access network (OAN) as much as possible by configuring an optical line terminal (OLT) and optical network terminals (ONTs) in the OAN to support a maximum power-saving mode. According to the method, upon the application of power, an ONT operates normally in an activation mode. The ONT then determines whether the requirements for switching from activation mode to power-saving mode are satisfied. If the requirements are satisfied, the ONT transmits a sleep signal to an OLT, which is a message notifying that the ONT will soon switch to power-saving mode. Thereafter, the ONT switches to power-saving mode and cuts off power for all functions except for power for monitoring and controlling external inputs. The ONT then determines whether the requirements for switching from power-saving mode to activation mode are satisfied.
