Patent number: 8656034Abstract: The invention relates to the field of data transmission in a network of distributed stations. In this case, the network contains a network connection switching unit which sets up desired connections between network subscriber stations arranged in a star formation. The network system under consideration has provision for network stations to log on in the network using a logon message and to log off using a logoff message. Regular turn-on and turn-off operations allow these logon and logoff messages to be sent. One problem is that when the network cable for a network station is manually decoupled from the network connection switching unit (11) the decoupled network station is no longer able to transmit the proper logoff message. The invention solves the problem through additional means in the network connection switching unit. These detect the decoupling of a network station. The detection means then initiate the automatic sending of the proper logoff message by the network connection switching unit.Type: GrantFiled: August 18, 2005Date of Patent: February 18, 2014Assignee: Thomson LicensingInventor: Ingo Huetter

Patent number: 6529530Abstract: When a CPU core 53 of a node detects change of data which comes into the node from a load 60 connected thereto on the input side, and thereby the CPU core 53 and a transmission control circuit 52 wake up, the node transmits a frame for waking-up to a transmission line 4. However, when the node receives a frame for waking-up from another node via the transmission line 4 and thereby wakes up, the node does not transmit a frame for waking-up. Thus, an increase in traffic at the time of waking up is reduced and data transmission in a normal operation mode is started soon, so that the speed of data transmission is increased.Type: GrantFiled: August 17, 1999Date of Patent: March 4, 2003Assignee: The Furukawa Electric Co., Ltd.Inventors: Eiji Ichii, Hiroo Moriue
