Abstract: A switching power converter provides regulated voltage to a load. The switching power converter comprises a transformer including a primary winding coupled to an input voltage and a secondary winding coupled to an output of the switching power converter. The switching power converter further comprises a power switch coupled to the primary winding and a rectifier coupled to the secondary winding. Current is generated in the primary winding responsive to the power switch being turned on and not generated responsive to the power switch being turned off. A detection circuit measures a voltage across the rectifier. If the detection circuit detects a decrease in the voltage across the rectifier outside of a blanking period, the detection circuit generates a current pulse in the secondary winding of the transformer. A fast power-on-reset device generates a startup signal to activate the detection circuit at an end of the blanking period.

Abstract: A circuit for reducing jitter in a digital signal is provided, comprising a clock and data recovery stage operative to receive an input data signal and generate in response thereto a recovered data signal, a recovered clock signal, and an unfiltered interpolator code; a filter stage operative to receive the unfiltered interpolator code and generate in response thereto a filtered clock signal; and a memory component operative to receive the recovered data signal, the recovered clock signal, and the filtered clock signal; sample the recovered data signal using the recovered clock signal; store the resulting sampled bits; and generate an output data signal by selecting stored bits using the filtered clock signal.

Abstract: This technology is directed to compressing dependency graphs in online communities, e.g., social networks, by determining a dependency graph and by performing a transitive reduction on the dependency graph. The transitive reduction may be used in various applications, e.g., for loading software modules in social networks, without causing inefficiencies by loading the same modules multiple times. In some instances, the systems and methods include 1) sorting nodes (e.g., modules) in the dependency graph into a list in a valid dependency order (a node depends only on nodes earlier in the list), 2) iterating over the list while building a map from any node to all of its dependencies, 3) iterating through the dependency graph in reverse order, and for each node, iterating through its dependencies (also in reverse order) and removing each dependency if it is a transitive dependency of any of the previous dependencies of that node.

Abstract: A method, apparatus, and system for an order proxy are provided. In an embodiment, an example order proxy system implemented in software, hardware logic, or a combination of both, may be configured to allow an e-commerce digital shopping cart to submit and complete transaction orders. An embodiment uses various necessary information and steps for completing a transaction into an e-commerce system without there being any prior software integration between fields and transaction processing steps coded into the shopping cart. A first commerce system may complete a transaction order through the order proxy system. Additionally, the order proxy system may have a merchant cart configuration map module to map the shopping cart information into a merchant server's shopping cart process.

Abstract: A method, apparatus, and system for securing internet applications including a first internet application hosted on a source server and stored on a physical storage medium of the source server. The internet application is served across a network onto a client machine and contains code scripted to temporarily install on the client machine. The internet application shell container contains code scripted for a user interface to solicit sensitive data from a user of the client machine and a dual encryption security system including. A security communication manager employs an encrypted protocol where the identity of both a sender and a receiver of the transmitted data are both authenticated and the authentication between the client and source server is bilateral. Additionally, the security communication manager transmits the solicited sensitive data from the user interface by cooperating with the encryption engine. The systems and methods can identity theft and fraudulent activity.
