Abstract: An inter-integrated circuit bus arbitration system includes a first master circuit, a second master circuit, an analog switch circuit, an initial state identification circuit, and a selection control circuit. When the first master circuit is initiated to transmit data, the initial state identification circuit generates a first initial pulse signal. When the second master circuit is initiated to transmit data, the initial state identification circuit generates a second initial pulse signal. If the first initial pulse signal leads the second initial pulse signal, the selection control circuit generates a first control signal to make the analog switch circuit establish electrical connections between the first master circuit and an external data line and an external clock line when receiving the first control signal.

Abstract: A measurement fixture includes a base, a lateral plate, a top plate, a movable measurement plate and a dimensional measurement component. The lateral plate has a piercing hole and a plurality of guiding pillars. The base and the top plate are respectively disposed on opposite sides of the lateral plate. The movable measurement plate utilizes a plurality of guiding holes to movably connect with the plurality of guiding pillars. The movable measurement plate includes an opening portion and an indicating portion adjacent by the opening portion. The dimensional measurement component movably passes through the piercing hole. A first end of the dimensional measurement component protrudes from a surface of the lateral plate facing a blade server to touch the blade server, and a second end of the dimensional measurement component protrudes from the other opposite surface of the lateral plate to partly protrude from the opening portion.

The first power housing has a plurality of engaging portions. The second power housing has a plurality of engaging grooves. Each of the engaging grooves is corresponding to one of the engaging portions. Each of the engaging grooves is L-shaped and has an opening. When the second power housing is disposed on the first power housing and the engaging portion enters the engaging groove through the opening, the second power housing is capable of moving with respect to the first power housing in a horizontal direction, such that the engaging portion is engaged with the engaging groove.

Abstract: A firmware update method and system, includes: a first south bridge chip generating a first update request signal and a first firmware update file; a second south bridge chip generating a second update request signal and a second firmware update file; a controller including a firmware unit, receives the first and second update request signals, judges and generates a control signal; and a switching module switches according to the control signal, selectively conducts with the first or second south bridge chip, receives the first or second firmware update file and sends it to the controller firmware unit for storage. The controller controls the switching module to decide to south bridge chip the current controller is connected, ensures that the controller is connected to only one south bridge chip at a time and merely the firmware update file sent by one south bridge chip is accepted to update the controller firmware.

Abstract: An assembly mechanism and a server system therewith are disclosed. The server system includes a casing, a first module and a second module. The first module is installed inside the casing. The second module is selectively installed inside the casing. The assembly mechanism includes a frame mechanism, a tray, a first fixing member and a handle member. The frame mechanism is disposed around the first module. The tray is combined with the second module and supports the second module above the first module cooperatively with the frame mechanism. The first fixing member is fixed on the frame mechanism. The handle member is pivoted to the tray. The handle member activates the tray to approach the first module as being rotated in a first direction. The handle member activates the tray to separate from the first module as being rotated in a second direction.

Abstract: A cable limiting device is for connecting to a connection device of a server. The connection device includes a motherboard, a bridgeboard, and a port disposed on the bridgeboard and coupled to the motherboard. The cable limiting device includes a side plate having a longitudinal opening and a transverse slot communicated with each other, a casing, and a cable fixed in the casing. A pillar of the casing passes through the longitudinal opening to be slidably disposed through the transverse slot and be movable relative to the transverse slot for making the casing away from or close to the side plate. When the cable is connected to the port, the casing is away from or close to the side plate with movement of the pillar in the transverse slot for guiding a gold-plated terminal of the cable to be inserted into the port and establishing signal transmission via the bridgeboard.

Abstract: After receiving at least one touch point on a touch screen, detect at least one initial position of the touch point on the touch screen. When the touch point slides away from the initial position, scroll an image displayed on the touch screen according to at least one sliding action of the touch point. Then detect the number of the touch points on the touch screen, and update a scrolling rate of the image displayed on the touch screen according to the number of the touch points moving on the touch screen. The scrolling rate of the image is directly proportional to the number of the touch points moving on the touch screen.

Abstract: An electronic device includes a casing and a rotary flap door device. The rotary flap door device is installed inside the casing and includes a base plate and a door member. The base plate is mounted on the casing. A base constraining structure and a base engaging structure are formed on the base plate. The door member includes a door body, a door limit part and a door engaging portion. The door body is rotably disposed on the base plate. The door limit part extends from the door body and is for embedding into the base limit part. The door engaging portion protrudes from the door body and is for engaging with the base engaging portion.

Abstract: A data center network flow migration method includes detecting a utilized loading value in each switch of a plurality of switches in the data center network by a controller according to topology information of the data center network. The controller re-establishes a plurality of link paths corresponding to the plurality of switches in the data center network according to the utilized loading value in each switch and a disjoint edge node divided spanning tree algorithm. In these re-established link paths corresponding to the plurality of switches in the data center network, if the utilized loading value of at least one link path is greater than a threshold value, the at least one link paths with the utilized loading value greater than the threshold value is rerouted by a controller according to a flow migration algorithm.

Abstract: Data center network provisioning method includes partitioning a plurality of virtual machines in the data center network into a plurality of groups according to topology information of data center network. A plurality of virtual machines in each group is assigned to a plurality of servers in the data center network. A pair-wised transmission path of the plurality of servers is assigned according to a traffic load of each switch in the data center network.
