20130057323 | INTEGRATED CIRCUIT FOR CONTROLLING A SWITCH OF A CURRENT PATH WITH LEADING EDGE BLANKING DEVICE OF THE CURRENT SIGNAL - An integrated control circuit of a switch is described, which is adapted to open or close a current path; said integrated circuit includes a comparator to compare a first signal with a second signal representative of the current flowing through said current path. The comparator outputs a third variable signal between a low logic level and a high logic level according to whether said second signal is lower than said first signal or vice versa; the integrated circuit has a driver to generate a signal to drive said switch in response to the third signal, and is configured to detect a spike on the leading edge of said second signal and to blank said third signal for a first blanking time period which depends on a turn-on delay of said switch and a second blanking period which depends on the duration of said spike on the leading edge of said second signal. | 03-07-2013 |
20130329470 | CONTROL DEVICE FOR A DC-DC CONVERTER - A control device controls a switching circuit of a DC-DC converter. The switching circuit includes a half-bridge with at least first and second switches connected between an input voltage and a reference voltage. The converter comprises a transformer with a primary coupled with the center point of the half-bridge and a secondary coupled with a load. The control device comprises an error detector configured to determine an error signal representing a difference between a first signal representative of the voltage across the load and a first reference signal and a frequency controller configured to increase the switching frequency of the half-bridge when the error signal is kept below a second signal. | 12-12-2013 |
20140016362 | BURST-MODE CONTROL METHOD FOR LOW INPUT POWER CONSUMPTION IN RESONANT CONVERTERS AND RELATED CONTROL DEVICE - An effective method enhances energy saving at low load in a resonant converter with a hysteretic control scheme for implementing burst-mode at light load. The method causes a current controlled oscillator of the converter to stop oscillating when a feedback control current of the output voltage of the converter reaches a first threshold value, and introduces a nonlinearity in the functional relation between the frequency of oscillation and said feedback control current or in a derivative of the functional relation, while the control current is between a lower, second threshold value and the first threshold value, such that the frequency of oscillation remains equal or smaller than the frequency of oscillation when the control current is equal to the second threshold value. Several circuital implementations are illustrated, all of simple realization without requiring any costly microcontroller. | 01-16-2014 |

20090080387 | Method and system for controlling operation of a communication network, related network and computer program product therefor - In a network wherein nodes request services adapted to be provided via a plurality of home agents, a system includes nodes configured for having associated a service identifier identifying a service requested by the at least one node, the system being configured for selecting the home agents to provide the services requested, wherein the home agents are selected based on the service identifiers. A node may thus have a first service identifier and a second service identifier identifying two different services adapted to be provided, even simultaneously, by a first and a second home agent respectively. | 03-26-2009 |
20130343304 | System and Method for Configuring Multiple IP Connections - In one embodiment, a method of configuring multiple per user access connections includes receiving, by an access gateway (AG) from an access point (AP), a first extensible authentication protocol (EAP) message including a first capability of a user equipment (UE) and transmitting, by the AG to an authentication, authorization and accounting (AAA) server, a second EAP message including the first capability of the UE and indication second capability of the AG. The method also includes receiving, by the AG from the AAA server, and an AAA message including a negotiated connection capability version and AAA message parameters and transmitting, by AG to the AP, a third EAP message including the negotiated connection capability version. | 12-26-2013 |

20140307651 | Internet Protocol Address Registration - A computer program product implemented in an Internet Protocol (IP) edge node positioned in a fixed access network, the computer program product comprising computer executable instructions stored on a non-transitory computer readable medium such that when executed by a processor cause the IP edge node to receive an address registration request from a residential gateway (RG), wherein the address registration request comprises an IP version six (IPv6) address of a third Generation Partnership Project (3GPP) visiting mobile host connected to a local fixed network associated with the RG and a host identifier (ID) assigned to the visiting host and not to any other host in the local fixed network; establish an IP Connectivity Access Network (IP-CAN) session for the visiting host; and manage quality of service (QoS) for the visiting host independently of other hosts in the local fixed network by managing the visiting host IP-CAN session. | 10-16-2014 |
