摘要:
Digital timing error detection systems and techniques are described. The described techniques are independent of polarization and differential-group-delay and are used to perform timing recovery of polarization-multiplexed coherent optical systems.

A merchant profile builder (MPB) is provided. The complete merchant profiling process is split into three pieces: Data Preprocessing, Weekly Summary Calculation, and Merchant Profile Calculation. In the Data Preprocessing stage, authorization data and daily fraud data are processed on a weekly basis to yield: an authorization extract file and fraud authorization data, each of which are sorted by a merchant key. In the Weekly Summary Calculation stage, the files output by the Data Preprocessing stage are used as input to compile basic statistics for each merchant based only on data for one week. There are separate weekly summaries for authorizations and fraud authorizations. In the Merchant Profile Calculation stage, the weekly summaries from the 16 most recent weeks are combined together and averages are calculated and output a set of merchant profiles and a set of default profiles.

SOI devices for plasma display panel driver chip, include a substrate, a buried oxide layer and an n-type SOI layer in a bottom-up order, where the SOI layer is integrated with an HV-NMOS device, an HV-PMOS device, a Field-PMOS device, an LIGBT device, a CMOS device, an NPN device, a PNP device and an HV-PNP device; the SOI layer includes an n+ doped region within the SOI layer at an interface between the n-type SOI layer and the buried oxide layer; and the n+ doped region has a higher doping concentration than the n-type SOI layer.
摘要:
At least a first capacitor is formed on a substrate and connected to a first differential node of a differential circuit, and the first capacitor may be variable in capacitance. A second capacitor is formed on the substrate and connected to a second differential node of the differential circuit, and the second capacitor also may be variable. A third capacitor is connected between the first differential node and the second differential node, and is formed at least partially above the first capacitor. In this way, a size of the first capacitor and/or the second capacitor may be reduced on the substrate, and capacitances of the first and/or second capacitor(s) may be adjusted in response to a variable characteristic of one or more circuit components of the differential circuit.
摘要:
A camera assembly includes a camera module, a dustproof cover and a sealing ring. The dustproof cover is assembled in front of the camera module. The sealing ring is hermetically sandwiched between the dustproof cover and the camera module. The camera module, the sealing ring and the dustproof cover cooperatively define a closed chamber. A portable electronic device using the camera assembly is also provided.

A data storage system includes a first memory, a controller, a counting module, and a checking and correcting module. Copyback operations are performed in the first memory. The controller couples the first memory to the counting module and the checking and correcting module. The counting module provides a counting operation for the copyback operations at different logic addresses of the first memory and, according to a counting result of the counting operation, determines whether a checking and correcting requirement has been satisfied by any of the logic addresses. The checking and correcting module receives data read out from the first memory, wherein the received data corresponds to a satisfying logic address, and checks the received data and corrects the received data when it is checked that the received data is incorrect, to correct the first memory accordingly.

Embodiments of the present invention disclose a service transmission processing method, a node device and a network system are provided. One method includes: receiving service data after relay processing by a 3R relay node, where the relay processing includes terminating and regenerating an Optical Channel (OCh) of the service data, and when the OCh is terminated, transparent transmission is performed on an Optical channel Transport Unit (OTU); and performing defect detection on a path of the OTU to obtain a detection result of the path of the OTU. Another method includes: obtaining an overhead in an Optical Transport Network (OTN) frame; and judging whether the overhead includes a Client Signal Fail (CSF) inserted after a signal fails, and if the overhead includes the CSF, determining a path where a defect occurs according to the CSF.
摘要:
The automated social networking graph mining and visualization technique described herein mines social connections and allows creation of a social networking graph from general (not necessarily social-application specific) Web pages. The technique uses the distances between a person's/entity's name and related people's/entities names on one or more Web pages to determine connections between people/entities and the strengths of the connections. In one embodiment, the technique lays out these connections, and then clusters them, in a 2-D layout of a social networking graph that represents the Web connection strengths among the related people's or entities' names, by using a force-directed model.
摘要:
A computer-implemented method for providing customer recommendations for a product is disclosed. For each target product for which a customer recommendation is desired, one or more customers likely to purchase the target product are identified using a mathematical model that considers customers' prior purchases of products that are similar or related to the target product.
