Abstract: Techniques are described for providing a storage service that stores information about large numbers of transactions in a persistent manner, such as with a high degree of reliability, availability and scalability based at least in part on use of a distributed computing and storage system. In some situations, the transaction information storage service stores various information about transactions that each include at least one monetary payment (e.g., a micro-payment) between financial accounts of two or more of numerous users having accounts with one or more entities. The transaction information storage service may be provided by or otherwise affiliated with a merchant, and customers of the merchant may purchase usage of the storage service for programs executed by or otherwise affiliated with the customers, with the storage service available to remote executing programs via a defined API of the storage service, such as a Web services-based API.

Abstract: A power measurement and calibration system provides power and line frequency measurements by using a bandpass filter having complex voltage and current outputs from which real and imaginary power components can be determined. Calibration of the filter may be omitted if a complex wavelet filter is used to implement the bandpass filter and a determination of line frequency can also be provided for downstream use. A processor receiving data from the output of the filter can compute real and imaginary power, power factor and the line frequency. The filter may be implemented by a processor executing program instructions, or a digital circuit implementing the filter and optionally a CORDIC rotator for computing the current-to-voltage phase relationship can provide input to the processor for power measurement and calibration of the sample rate to line frequency relationship and for other uses.

Abstract: Data traffic, latency, and power consumption in a mobile unified communication environment are reduced by optimizing communication between a mobile client application and a mobile data server through determining optimum delay between exchanged messages and/or filtering portions of data not relevant to the mobile client application at the server. Additional optimizations include providing mobile client application relevant updates in an intelligent fashion based on user activity, screen resolution or displayed information, relevant contacts and relevance of information, and similar characteristics.

Abstract: Method and apparatus for metering network services, for example Web services. In embodiments, a network services metering system may collect network service usage information via an add usage interface and store the usage information in a database. In one embodiment, the usage information may be partitioned into two or more partitions. Once the usage information has been aggregated and stored, the metering system may be queried to obtain usage statistics such as aggregate usage over specific time intervals. In one embodiment, a pipeline mechanism that generates and processes batches of usage information may be implemented for adding usage information to the database. The pipeline mechanism may help to reduce or eliminate redundancy and loss of usage information, and may make the metering system linearly scalable in multiple dimensions.

Abstract: Network disconnections are automatically detected between a client application and a server When a disconnection is detected by either the client or server, a determination is made as to whether the disconnection is a temporary disconnection or a longer-lasting disconnection. While disconnected, attempts are made to automatically reconnect the client and server. During the disconnected period, a subset of communication functions remain operable. When the connection is restored, presence/availability information is automatically delivered to the client.

A communication channel is established between at least two instances of a presence application that are running on different devices. A device that is associated with an instance of a presence application is remotely commanded by a received message from the communications server from another instance of the presence application on a different device.

Abstract: A method and apparatus for automatically securing non-volatile (NV) storage in an integrated circuit provides improved resistance to code copying and reverse-engineering attacks. External interfaces that provide read access to the NV storage are be disabled, for a predetermined time after a reset or other initialization signal is received. An internal lock state bit or key is checked as well as an external lock prevent indication. If the lock prevent indication is not received, or the internal lock state bit is already set, then the integrated circuit is operated under a locked condition, in which external access to the NV storage values is prevented. The lock prevent indication may be a signal provided during reset of the integrated circuit on a terminal that is used for another purpose after initialization of the integrated circuit.

Abstract: A method of separating a chroma data component from a video data stream includes determining a phase relationship between a color burst in digital video data samples of a composite video signal and a local clock signal which processes the digital video data samples. In response to determining the phase relationship, interpolation filtering is performed on the digital video data samples corresponding to first and second display lines to generate phase aligned video data samples. Adaptive filtering is then performed utilizing the phase aligned video data samples corresponding to the first and second display lines to separate the chroma component from the digital video data samples corresponding to the first display line.

Abstract: A method and apparatus for reducing switching noise in a system-on-chip (SoC) integrated circuit including an analog to digital converter (ADC) provides for reduced noise in the ADC conversions. Sampling circuits of the ADC are operated by sampling clock signals and digital circuits and other noise-generating circuits such as power converters, are operated by digital circuit clock signals. Both sets of clock signals are derived from the same master clock by a clock generator circuit, but an offset is applied in the clock generator circuit to move the edges of the digital circuit clock signals away from critical sampling intervals corresponding to edges of the sampling clocks. In one embodiment, the offset is applied by a processor core that forms part of the digital circuits by setting a value in the clock generator, which the clock generator then loads into the divider after halting the clock to the digital circuits.

Abstract: A method and system for synchronizing video information derived from an asynchronously sampled video signals provide a mechanism for using asynchronous sampling in the front-end of digital video capture systems. A ratio between the sampling clock frequency and the source video clock frequency is computed via an all digital phase-lock loop (ADPLL) and either a video clock is generated from the ratio by another PLL, a number to clock converter or the ratio is used directly to provide digital synchronization information to downstream processing blocks. A sample rate converter (SRC) is provided in an interpolator that either acts as a sample position corrector at the same line rate as the received video, or by introducing an offset in the ADPLL, the video data can be converted to another line rate via the SRC.
