Preventing TCP from becoming too conservative too quickly
A technique that addresses the problem of a TCP connection's throughput being very vulnerable to early losses implements a pair of controls around ssthresh. A first control is a loss forgiveness mechanism that applies to the first n-loss events by the TCP connection. Generally, this mechanism prevents new TCP connections from ending slow-start and becoming conservative on window growth too early (which would otherwise occur due to the early losses). The second control is a self-decay mechanism that is applied beyond the first n-losses that are handled by the first control. This mechanism decouples of ssthresh drop from cwnd and is thus useful in arresting otherwise steep ssthresh drops. The self-decay mechanism also enables TCP to enter/continue to be slow-start even after fast-recovery from a loss event. |

The control device is provided with an actuating element, comprising a shape memory material and operatively associated with maneuvering means for the circuit breaker. When this shape memory material performs a state transition, the actuating element causes the movement of said maneuvering means from a first operative position, associated with an open configuration of the circuit breaker, to a second operative position, associated with a closed configuration of the circuit breaker. |

Electric switching device
An electric switching device for a low voltage circuit includes an electronic unit configured to be operatively connected to a first communication bus implementing a first communication protocol, a communication module configured to be operatively connected to the first communication bus and to a second communication bus implementing a second communication protocol, which is different than the first communication protocol. The communication module is configured to place the first communication bus in communication with the second communication bus, and to detect a condition of the switching device and make it available externally thereto by means of the first communication bus and/or the second communication bus. |

Electromagnetic relay
An electromagnetic relay includes a contactor including a fixed contact and a movable contact, and an electromagnet device for moving the movable contact. The electromagnet device includes a coil generating a first magnetic flux by energization, a tubular body including a permanent magnet generating a second magnetic flux in a direction identical to a direction of the first magnetic flux and having a hollow extending in a center axis direction, a movable element disposed in the hollow of the tubular body and reciprocating in the center axis direction, and a yoke forming a magnetic circuit passing together with the movable element and the tubular body. The magnetic circuit allows at least one of the first and second magnetic fluxes to pass through the magnetic circuit. The electromagnet device is configured to, when the coil is energized, move the movable contact to a first position by attracting the movable element with the first magnetic flux and the second magnetic flux. The electromagnet device is configured to, when energization of the coil is suspended, move the movable contact to a second position different from the first position. This electromagnetic relay is easily designed and reduces power consumption at a low cost. |
