Abstract: The present invention provides overbased detergents as lubricating oil additives effective for the lubrication of mechanical components in land and marine engines, such as, for example, hydraulic systems, transmissions, two-stroke and four-stroke vehicular engines, trunk piston and two-stroke crosshead marine engines. These overbased detergents lead to improved detergency and thermal stability performances versus high overbased sulfonates. Moreover, they are more compatible with commercial phenates than conventional sulfonates.

Abstract: Instead of estimating a saturation value for an ADC color comb register of an LCD made in a region without a standard color bar, a standard color bar of another geographic region is used to calculate the saturation value for the register so as to optimize the color of images presented on the LCD.

Abstract: A technique protects, in a communications network, a point-to-multipoint primary tree between a root node and primary leaf nodes of the network if a failure occurs affecting one of the primary leaf nodes. One network node receives from another upstream network node a request to protect the primary tree via a backup branch leading to a backup leaf node situated downstream from said node, if a failure affecting one of the primary leaf nodes to be protected occurs, the backup leaf node being associated with the primary leaf node to be protected. If the node is connected directly to the downstream primary leaf node to be protected, it configures a backup routing rule for routing packets from an upstream primary branch to the downstream backup branch and, possibly, to the downstream primary branch(es) and is activated in the event of a failure affecting the primary leaf node to be protected.

The link may have three states: a non-connected state if said two routers cannot be directly connected, a virtual connection state wherein a virtual metric is assigned to said link between said head end router and said tail end router of the same communication, and a real connection state wherein a real metric is normally assigned to said link.
