An on-vehicle Ethernet connector includes a housing, a terminal, a shield member, and an ESD casing; the housing formed in a barrel shape and having a U-shaped protection structure; the terminal inserted on a bottom of the housing; the shield member inserted in the pillar bodies; the ESD casing mounted around the housing; the U-shaped protection member disposed in the housing and having a plurality of pillar bodies connected and arranged around the terminal; and a sectional view of the plurality of pillar bodies around the terminal being formed in a U shape. The U-shaped protection structure surrounding the terminal prevents the terminal from being accidentally touched, thus increasing the stability and security of the connector. The shield member shields around the terminal. The U-shaped protection structure formed of plastic material provides dust-proof, water-proof, insulation, and accidental contact prevention.

Systems and methods associated with media hub devices are provided that passively monitor user devices and transmit targeted media through in-channel transmissions that use the same channel used to monitor the user devices, or shifted channel transmissions that are different than the channel used to monitor the user devices. For example, a media hub device may passively monitor customer devices by scanning a wireless communication channel and obtaining device identification information transmitted by a user device that communicates the device identification information via the wireless communication channel. A media hub device may link the user device with a particular user or may anonymously monitor user behavior, through the monitored user device, without explicit knowledge of the identity of the user. Targeted media may be provided to the user device either in-channel using the same channel used to passively monitor the user device or a shifted channel using a different channel.

An optical transceiver includes an optical transmitter, an optical receiver, a first processing unit for controlling a section of the optical transmission circuit, a second processing unit for controlling a section of the optical reception circuit, and a signal line. First and second memory regions constitute a MDIO register space. The selection signal is set to a first level when the first memory region includes a MDIO register, and alternatively is set to a second level when the second memory region includes the MDIO register. The first processing unit responds to another MDIO frame having an OP code set to other than 00h when the selection signal is at the first level, and the second processing unit alternatively responds to the another MDIO frame when the selection signal is at the second level.

A network device and a vertical interface are disclosed. The network device includes a panel (31), a printed circuit board PCB (32), and N vertical interfaces (33). The vertical interface is an interface whose width is less than a height. The panel is connected to the PCB, and the panel includes N vertical openings, where N is greater than or equal to 2. Each of the N vertical interfaces includes a housing (331), a connection component (332), and a connector (333). The housing is configured to accommodate the vertical interface into the panel by using one of the N vertical openings on the panel. The connection component is configured to connect the vertical interface to the PCB. The connector is configured to transmit a signal to the PCB by using the connection component.

A coupling device that couples a first bus system to a second bus system configured to provide bidirectional communication between the first bus system and the second bus system comprising data transfer means for transmitting forward-directed data from the first bus system to the second bus system and for transmitting backward-directed data from the second bus system to the first bus system, data manipulation means for manipulating forward-directed data and/or backward-directed, and an instruction memory for storing manipulation instructions relating to the manipulation of data by the data manipulation means.

Upon acceptance of a setting instruction for communication equipment (110), a first control apparatus (200) transmits a first setting command to the communication equipment, and updates first management information to information associated with first setting. When an event is detected, a second control apparatus (300) transmits a second setting command to the communication equipment and transmits a second setting notification to the first control apparatus. When the first control apparatus receives the second setting notification, the first control apparatus updates the first management information to information associated with second setting.
