    Abstract: An integrated circuit providing a function of substituting LED open and a protection against static electricity and surge can be coupled and parallelly connected to an LED. The integrated circuit comprises a thyristor, such as SCR, with three electrodes, a transistor for a gate of the thyristor to trigger signals, and a voltage detecting circuit. When the LED breaks due to open, a proper current is acquired via the voltage detecting circuit so as to trigger the SCR, thereby providing a substitute current route that allows the rest of the serially-connected LEDs to keep lighting. When static electricity or surge occurs at two ends of the LEDs, the integrated circuit provides a route to guide the static electricity or the surge, which protects the LEDs.

    Abstract: An Ethernet switch for use in an Ethernet network comprises a set of ingress ports for receiving data frames and a set of egress ports. A memory is associated with each ingress port and stores forwarding information indicating one or more of the egress ports to which data frames received by that ingress port should be forwarded. A control or management interface receives information about a network connection established, or to be established, through the switch. A switch controller causes forwarding information to be stored in a memory associated with a first ingress port which the network connection will use, on the basis of the received information about a network connection. Forwarding information is not stored in a memory associated with a second of the set of ingress ports which the network connection will not use. Preferably, the switch controller causes forwarding information to be stored only in a memory associated with the first ingress port which the network connection will use and not to be stored in a memory associated with any of the other ingress ports.

    Abstract: A method and device for identifying degradation in service quality for a wireless media service. The wireless media service has a known expected packet generation rate, which may be determined by the device based upon the codec and payload size selected on initiating the media service. At a receiving device, the packets actually received by the device from the other termination point are counted over a time period, and this number is compared with the number of packets that were expected based upon the known packet generation rate. From this comparison a packet loss rate may be determined. If the packet loss rate exceeds a threshold level, then the device may issue a user alert, terminate the service, or take other action. The threshold level may be established based upon a packet loss rate corresponding to a significant degree of service quality degradation.

    Abstract translation: 一种用于识别无线媒体服务的服务质量下降的方法和装置。 无线媒体服务具有已知的预期分组生成速率，其可以由设备基于在启动媒体服务时选择的编解码器和有效载荷大小来确定。 在接收装置中，从另一终端点实际接收到的分组的分组在一段时间内进行计数，并将该数量与根据已知分组生成速率预期的分组数进行比较。 从该比较可以确定分组丢失率。 如果丢包率超过阈值级别，则设备可能发出用户警告，终止服务或采取其他操作。 可以基于对应于显着程度的服务质量降级的分组丢失率来建立阈值水平。

    Abstract: The present invention discloses an overload protection control mechanism for a power supply, wherein a control mechanism installed between two connectors automatically switches the DC power states of the output signal of the overload protection circuit according to the electric connection state between two connectors. Thereby, the present invention not only can prevent the user, who lacks the knowledge of the overload protection circuit, from incorrectly operating the overload protection circuit but also can protect electronic devices from the damage induced by that an unintended touch switches the overload protection circuit erroneously.
