  • Patent number: 8004980
    Abstract: A data flow rate policer enforces data flow policies for a number of data flows using a probabilistic policy enforcement mechanism. The policer includes a memory that stores the state of each data flow in a compact data structure. Additionally, the policer includes one or more policing engines that implement the actual data flow policies based on information derived from the data structures. The policing engines may be implemented in hardware to increase performance.

  • Patent number: 4749089
    Abstract: There is disclosed a rack for mounting a bicycle from a wall by means of a pair of horizontally spaced picture hooks, the rack comprising a relative flat base having rings pivotally mounted on the back side thereof each to fit within one of the hooks, a pair of legs having their upper ends carried by the base to dispose their lower ends in position in to engage the wall beneath the base, and a pair of arms each having one end pivotally connected to the base for swinging between an inner position in which its other end is beneath the lower end of the base and an outer position in which its other end extends therefrom in horizontally spaced relation with respect to the other arm, the legs being of such configuration as to be inwardly yieldable to permit the base to assume a more vertical position under the weight of the bicycle.
