Computing time-decayed aggregates under smooth decay functions
Aggregates are calculated from a data stream in which data is sent in a sequence of tuples, in which each tuple comprises an item identifier and a timestamp indicating when the tuple was transmitted. The tuples may arrive at a data receiver out-of-order, that is, the sequence in which the tuples arrive are not necessarily in the same sequence as their corresponding timestamps. In calculating aggregates, more recent data may be given more weight by a decay function which is a function of the timestamp associated with the tuple and the current time. The statistical characteristics of the tuples are summarized by a set of linear data summaries. The set of linear data summaries are generated such that only a single linear data summary falls between a set of boundaries calculated from the decay function and a set of timestamps. Aggregates are calculated from the set of linear data summaries. |

Weight normalization in hardware without a division operator
Weight normalization in hardware or software without a division operator is described, using only right bit shift, addition and subtraction operations. A right bit shift is performed on an expected sum to effectively divide the expected sum by two to provide a first updated value for the expected sum. An iteration is performed which includes: incrementing with a first adder a first variable by the first updated value of the expected sum to provide an updated value for the first variable; subtracting with a first subtractor a second weight from a first weight to provide a first updated value for the first weight; and performing a left bit shift on the second weight to effectively multiply the second weight by two to provide a first updated value for the second weight. |

Method for a cloud-based meta-file system to virtually unify remote and local files across a range of devices' local file systems
A system and process that establish a singular shared file system among devices in order to create a virtual representation of data on all of the devices via metadata indexing. This virtual representation of data means that the files are not actually stored on all devices and thus, with the exception of a single physical location, they do not need to take up any space (i.e. storage) on any additional device's hard drive. This allows for significant amounts of data to be virtually stored on each device, even if there is no physical storage room available for the data on each device. The system and process do not require data to be stored on a provider server, but instead stores only lightweight metadata, i.e., a small fraction of information about the files, online. |

Decoupling radio resource management from an access gateway
Particular embodiments provide an access gateway that facilitates communication between a plurality of access technologies. The access gateway facilitates data communication with an access terminal through a bearer path.
