  • Patent number: 10492331
    Abstract: A system for cooling a power distribution unit in a room of a data center includes an air handling system that supplies air to the room or removes air from the room through an opening in the room and an air directing device. The first end of the air directing device couples at the opening in the room. The second end of the air directing device couples with the power distribution unit at one or more openings of an enclosure of the power distribution unit. The air directing device directs air between the opening in the room and the one or more openings of the power distribution unit.

  • Patent number: 10090702
    Abstract: Reconfiguring a power system for an electrical load includes establishing a secondary feed to an electrical load that is receiving power from a primary power source. A set of secondary feed lines is coupled between a donor power source and a power input to the electrical load such that the set of secondary feed lines is configured to supply power from the donor power source to the electrical load. An automatic transfer switch is coupled in parallel with the set of secondary feed lines. The electrical load is transferred by the automatic transfer switch from the donor power source to the primary power source for the reconfiguration.

  • Publication number: 20180039307
    Abstract: An air channeling sub-system may include a mechanical cooling section and a direct evaporative cooling section. The direct evaporative cooling section may be downstream from the mechanical cooling section. Cooling air is channeled through the air channeling sub-system and into the room. If a first set of control conditions is met, the air channeling sub-systems is operated in an adiabatic mode. The adiabatic mode includes channeling cooling air through the direct evaporative cooling section to evaporate water into the cooling air. If a second set of control conditions is met, the air channeling sub-system is operated in a hybrid mode. The hybrid mode includes channeling cooling air through the mechanical cooling section to remove heat from the cooling air and channeling the cooling air through the direct evaporative cooling section to evaporate water into the cooling air.

  • Patent number: 8887026
    Abstract: A method for error detection includes storing in an associative memory multiple data entries, each data entry including a data item together with one or more check symbols computed with respect to the data item. A predetermined sequence of search keys is applied to the memory, thereby causing the memory to generate, in parallel, match results with respect to the data entries. The match results are processed in order to identify an error in at least one of the data entries.

  • Patent number: 8504510
    Abstract: A method for processing data includes encoding a finite automaton, which includes states and transitions between the states that express a plurality of predefined patterns, by grouping the states of the automaton into sets according to a common property shared by the states in each set, and assigning codes to the states according to the grouping. The codes are stored in an electronic memory, along with rules that are associated with the patterns. The automaton is traversed in order to identify one or more of the patterns in an input sequence of data elements by iteratively reading out the codes from the memory responsively to the data elements and to the codes that have been previously read out. Upon identifying a given pattern in the input sequence, an associated action is performed.
