Abstract: Systems, devices, and techniques relating to network upgrade and protocol selection in wireline communication networks are described. A described network device includes ports to connect with destination devices over wireline transmission mediums, wireline transmission mediums respectively comprising at least one pair of wires for transmitting and receiving data; a packet processor configured to forward packets to and from the ports; first transceiver circuitry configured to communicate using an Ethernet protocol over at least a portion of the wireline transmission mediums; second transceiver circuitry configured to communicate using an OFDM broadband protocol over at least a portion of the wireline transmission mediums; and a controller.

Abstract: In this sewing machine, in which the amplitude and direction of the feeding of the fabric to be sewn are controlled by an electric motor slaved to an electronic pilot-control circuit, the bobbin (16), its drive mechanism (17, 19, 10) and the drive mechanism (4*-17*) for feeding the fabric to be sewn are mounted on an intermediate support (6) that is solid with the body of the motor (11), which is attached to the frame (2) of the machine by a sleeve (23) engaging the inside of the lower arm of the frame.
