Abstract: An approach is provided for reliable provision of targeted, status-based messaging to a client terminal in a computer network, such as a wide area resource-based network. A terminal node receives a message originating from a client terminal, wherein the terminal node serves as an entry point to, and services communications connections over, a wide area network for the client terminal. The terminal node determines that the message comprises an initiation request for establishing a communications connection over the wide area network between the client terminal and a remote server, and that an intercept state is in effect. The terminal node establishes the communications connection as a local connection between the client terminal and the terminal node, and services the communications connection via a local server function, wherein the servicing of the communications connection via the local server function comprises a provision of status-based messaging to the client terminal.

Abstract: A diagnostic testing utility is used to perform single link diagnostics tests including an electrical loopback test, an optical loopback test, a link traffic test, and a link distance measurement test. To perform the diagnostic tests, two ports at each end of a link are identified and then statically configured by a user. The ports will be configured as D_Ports and as such will be isolated from the fabric with no data traffic flowing through them. This configuration can be static or can be on request or on errors. The ports will then be used to send test frames to perform the diagnostic tests. After completion of requested or on error testing the ports can return to normal operation.

Abstract: Apparatus and methods to regulate an input power applied to a plurality of light emitters are provided. A regulator device includes a plurality of switches and a control circuit that controls the plurality of switches. The plurality of switches selectively couple respective strings of the light emitters in series to the input power to emit light when deactivated. The control circuit may deactivate a number of the switches to couple the respective light emitters to the input power in response to a sensed operational parameter of the input power. The control circuit may adjust the number of the switches deactivated in response to a change in the sensed operational parameter of the input power. A number of the light emitters may be coupled to the input power regardless of the sensed operational parameter of the input power.

Abstract: Systems and methods for transferring power delivery between power sources to an electrical bus are provided. More particularly, a multi-source electrical power system can include an electrical bus having at least two power sources that each can be selectively coupled to the electrical bus, for instance, via contactors. At least one of the power sources can include a unidirectional or bidirectional power converter. The electrical power system can further include a control system configured to control the power output (e.g., the output voltage and the output current) of the power converter to provide no break power transfer of power delivery to the electrical bus between the first and second power sources. In example embodiments, the no break power transfer can be achieved by regulating the output current of a power source to a fixed current value and/or by using a virtual resistance programmed into a voltage regulator.
