  • Publication number: 20220060102
    Abstract: A system for charging a battery includes three sub-modules, each receiving a respective phase of a three-phase alternating current (AC) signal. The three sub-modules cooperate to transform the respective phases of the three-phase AC signal to a direct current (DC) signal by passing the respective phases of the three-phase AC signal through a respective semiconductor device configured to discontinuously modulate the respective phase of the three-phase AC signal to convert it to a DC signal provided to the battery to charge the battery.

  • Patent number: 11212599
    Abstract: A system and method is disclosed in which circuitry of a first controller of a first node on a first path within a transport network receives a first signal indicating a failure within the first path from a second controller. The first node is an end node of the first path. A first client signal failure clear signal is received from a second node upstream of the first node on the first path. The first client signal failure clear signal indicates that a non-restorable fault has been resolved such that the first path can be considered for carrying data traffic. The non-restorable fault is a failure at the source. Subsequent to receiving the first signal indicating the failure within the first path, a backward defect indication clear signal is transmitted to the second node, the backward defect indication clear signal indicating an absence of a failure in the first path.

  • Patent number: 10999195
    Abstract: Techniques are disclosed for seamless integration between a multicasting Virtual Private Network and an edge replicated multicast network. For example, a controller (e.g., software defined networking (SDN) controller) may facilitate the integration between a multicasting VPN network and an edge replicated multicast network through the selection of a multicast bridge node from virtual routers specified in the multicast replication tree, and sending information identifying the multicast bridge node to a provider edge (PE) device for the source VPN such that the PE device may use the information to steer multicast traffic from the source VPN site across the Layer 3 VPN network to the multicast bridge node of the receiver VPN site. When the multicast bridge node receives the multicast traffic, the multicast bridge node determines from the information that it is to receive the multicast traffic and to perform the edge replicated multicast using the edge replicated multicast tree.

  • Patent number: 10824351
    Abstract: Systems and methods are described in which circuitry of a first controller of a first node receives a first signal indicating an optical loss of signal within the first path. Circuitry of a second controller of the first node on the first path within a transport network generates a second signal indicating a failure within the first path. The first controller accessing a network topology database determines that restoration of the first path would be ineffective due to there being no alternate path, and signals a second node downstream in the first path with the second signal indicating the failure within the first path, and a third signal indicating that restoration of the first path would be ineffective due to there being no alternate path.

  • Publication number: 20200304313
    Abstract: The present approach relates to techniques for facilitating acquisition of electronic signatures (e-signatures) and/or acknowledgements in the context of electronic forms or documents. In one aspect, a designer may be used to configure tasks corresponding to signature or acknowledgment events that may be added to a person's to-do list or task management application or portal. Interaction with the task to complete the task may then be in accordance with the guidance programmed by the designer, such as to acquire a signature or acknowledgment. In certain aspects, the signature or acknowledgement tasks may be configured for display and completion on a mobile device (e.g., a handheld device such as a phone or tablet computer).
