摘要:
A method for obtaining an external IP address and its network protocol system are provided. A rack system of the network protocol system comprises a rack management controller (RMC), a power distribution unit and at least one node server. When a Dynamic Host Configuration Protocol (DHCP) service is lost in the rack system, a jumper of the rack management controller is detected to obtain an identification code. Then, a first temporary IP address of the rack management controller is obtained based on the identification code and a first table, and a first command package is sent to the power distribution unit by the rack management controller. After the first command package is received by the power distribution unit, an IP assign service is activated to set a second temporary IP address of the node server so that the node server can still communicate with the system management terminal.

A container system including cabinets, a main control unit connected to the cabinets and a heat dissipation zone is mentioned. The cabinet includes a plurality of serving zones each of which further includes a master server and at least one slave server. The heat dissipation zone is disposed at a side of the serving zone and coupled to the main control unit. Each slave server is coupled to the master server. The slave server includes at least one temperature sensor, and the temperature sensor is used for outputting temperature information to the master server when receiving the temperature demand. The master server collects the temperature information transmitted by each slave server. The master server forwards the temperature information to the main control unit. The main control unit drives the heat dissipation zone to dissipate heat of the serving zone according to the temperature information.

A container system and a monitoring method for the container system are provided. The container system includes a plurality of servers and a master server node. The servers are arranged in N areas. The master server node is coupled to the servers. The master server node selects one of a plurality of servers in an ith area to be a main node of the ith area. The main node collects temperature information of the servers in the ith area to transmit highest temperature information to the master server node. When the master server node cannot connect to the main node, the master server node selects one of other servers connected to the master server node in the ith area to be a replacing node, and adjusts the replacing node to be the main node of the ith area to collect the temperature information in the ith area continuously.

A surveillance system including a plurality of network video recorders (NVRs), a plurality of network video capturing devices and a plurality of streaming media presentation devices (SMPDs) is provided. The NVRs can receive and store digitized data packets, as well as transmit video/audio streams, event notifications, authorization codes and control signals. The network video capturing devices, each connected to a corresponding NVR among the plurality of NVRs via a network, can capture video/audio data and providing the digitized data packets by encoding the captured video/audio data. The SMPDs are connected to the plurality of NVRs via the network and can play captured video/audio data and alerting messages associated with the event notifications.

A representative AC signal generating circuit includes a first capacitor, a second capacitor, a first switch, a second switch, a third switch and a fourth switch. The first capacitor is coupled between a first node and an AC signal. The second capacitor is coupled between a second node and the AC signal. The first switch is coupled between the first node and a first DC signal. The second switch is coupled between the second node and a second DC signal. The third switch is coupled between the first node and an output terminal. The fourth switch is coupled between the second node and the output terminal. The first switch and the fourth switch are synchronous, the second switch and the third switch are synchronous and the first switch and the second switch are asynchronous.
摘要:
The invention provides a low power multiplexer configuration in a display panel and a display panel and an electronic device using the same. The multiplexer conducts one of source output signals into to red (or green or blue) sub-pixels under control of control signals. In every time a frame is scanned or changed, the red (or green or blue) sub-pixels driven by the source output signal via the multiplexer are always in the same signal polarity, so the multiplexer consumes low power because voltage swing rates in source output signals are very low or almost zero.

Methods for controlling display panels, in which the display panel comprises a plurality of pixels and wherein each of the plurality of pixels comprises a plurality of sub-pixels, are provided. A representative the method comprises: controlling a timing sequence for turning on the pixels such that at least one of: an average influence of coupling of each of the sub-pixels in two sequential time frames is the same; and an average influence of coupling of two of the sub-pixels on two adjacent rows of the sub-pixels is the same.
