Abstract: The present disclosure relates to a carrier. The carrier includes a carrying portion and a bracket device. The carrying portion includes a bottom portion, and a carrying space is formed on the bottom portion. The bracket device includes a first bracket, a second bracket and a third bracket. The first bracket is combined to the carrying portion and disposed around a periphery of the carrying portion. The second bracket is connected to the first bracket and combined to the carrying portion. The second bracket extends from a side of the periphery of the carrying portion to the other side of the periphery of the carrying portion through the bottom portion of the carrying portion. The third bracket is located at a side of the bottom portion of the carrying portion, for fixing the carrier to a carrying apparatus. The third bracket has an annular structural element.

Abstract: The present disclosure provides a carrier including: a main body; and a canopy assembly disposed to the main body or a cloth at least partially covering the main body. The canopy assembly includes: a canopy; and a canopy connecting assembly disposed between the canopy and the main body or between the canopy and the cloth, so that the canopy and the main body or the cloth are detachably connected with each other. The canopy connecting assembly includes: a canopy frame connected to a periphery of the canopy for supporting the canopy, and detachably disposed at a periphery of an opening of the main body; and a releasing operation element disposed on the canopy frame or the bracket device sleeved outside the main body, and operated to move from a locking position to an unlocking position, so that the canopy assembly is unlocked with respect to the main body.

Abstract: The present disclosure provides a locking base assembly. The locking base assembly includes: a base plate for placing an object thereon; and a locking mechanism mounted on the base plate for locking and unlocking the object. The locking mechanism includes: at least one releasing operation element capable of sliding between a locking position and an unlocking position with respect to the base plate; and at least one locking element is slidably disposed on the base plate. The locking element is capable of locking the object when the releasing operation element is in the locking position. The locking element moves along with movement of the releasing operation element to unlock (i.e., release) the object when the releasing operation element is operated to move from the locking position to the unlocking position. The present disclosure also provides a wheeled carrying apparatus including the locking base assembly.

Abstract: A network TAP includes four serial transceivers on a printed circuit board. Each serial transceiver has a medium-dependent interface and a serial differential interface that includes a differential input and a differential output. A passive tap circuit arrangement is configured to be operative at up to 10 Gbps or a higher data rate and configures the differential output signal from the differential output of the first serial transceiver as two single-ended signals that are received respectively by the respective differential inputs of the second and third serial transceivers. It also configures the differential output signal from the differential output of the second serial transceiver as two single-ended signals that are received respectively by the respective differential inputs of the first and fourth serial transceivers. In one embodiment according to the present invention, the four serial transceivers are pluggable transceiver modules.

Abstract: System, apparatus and method for transmission of 10/100Base-T Ethernet signals and electrical power over a coaxial cable are disclosed. The system includes a first media converter and a second media converter which are connected by the coaxial cable. The first media converter is connectable to a power sourcing equipment (PSE) and the second media converter is connectable to a powered device (PD). The two media converters are configured to enable transmission of 10/100Base-T Ethernet signals between the first network device and the second network device over the coaxial cable, and the two media converters are further configured to provide a passive DC circuit path between the PSE and PD for the PSE to deliver electrical power to the PD over the coaxial cable. According to one embodiment of the invention, the two media converters are swappable and are passive devices.

Abstract: A local area network having multiplexing means for establishing out-of-band channels along with corresponding Ethernet channels over shared transmission media of twisted pair cables. The out-of-band channels are configured for implementing a separate packet switching system for operating a dedicated network application such as IP telephony communications; power sourcing equipment (PSE) may be further provided for supplying inline power over the twisted pair cables; and means for network access control and device location tracking may be further implemented for the separate packet switching system.

Abstract: A new and improved Ethernet hub for providing visibility of data packet traffic in an Ethernet network is disclosed. The Ethernet hub includes a packet buffer being coupled with a plurality of network ports to enable full duplex data packet communications among connected network stations.

Abstract: A local area network that includes multiplexing means for establishing out-of-band channels along with corresponding Ethernet channels over shared network cabling; the out-of-band channels are configured dedicatedly for operating an IP telephony system including IP phones; a power sourcing equipment (PSE) may be further provided for remotely supplying power to the IP phones over shared network cabling; and means for access control and device location tracking may be further implemented for the IP telephony system.

Abstract: An Ethernet switch includes a plurality of network ports, wherein visibility of data packets traffic is configured by loading port-mirroring related configuration data from a configuration memory device into the Ethernet switch upon power-on reset. As a result, no manual configuration by a user is required, and the hardware cost of the Ethernet switch is reduced. The Ethernet switch is further configured to enable pass-through of Power over Ethernet (PoE) inline power between two selected network ports. A USB connector is further included and adapted for the Ethernet switch to receive input power from a USB port of a USB host device and for the Ethernet switch to send and receive data packets to and from the USB host device.
