摘要： Photovoltaic (PV) array emulators and methods are described. In one example, a method for use in testing a PV inverter includes coupling a first PV inverter to an alternating current (AC) power source. A second PV inverter is coupled to receive an output of the first PV inverter. The first PV inverter is operated to emulate a PV array and provide a DC power output to the second PV inverter.

摘要： Systems and methods of transferring a DNSSEC enabled domain from a losing hosting provider to a gaining hosting provider are described in which the transfer of the domain may be achieved without disruption to a DNSSEC validation of the domain. Systems and methods, such as those directed to registry and/or registrar servers, may include transferring a DNSKEY or Delegation Signer (DS) record from a gaining hosting provider to a losing hosting provider prior to transferring the domain from the losing hosting provider to the gaining hosting provider. A gaining hosting provider may sign DNS records of the domain with the gaining hosting provider DNSKEY prior to transferring the domain from the losing hosting provider to the gaining hosting provider. Additionally, a registry server, or similar device, may be configured to act as an intermediary between the losing hosting provider and the gaining hosting provider during the transfer process.

摘要： A communications module, and a consumer device comprising the communications model, is provided for use in a communication network with one or more consumer devices or “smart” appliances. The communications module includes a wireless transceiver for communication with the network, for example in accordance with the ZigBee protocol, and an interface for communicating with a host processor of the consumer device. The module receives scheduled event data over a wireless link on behalf of the host processor, and schedules events for execution by the host processor upon receipt of commands transmitted by the module. The communications module may include a virtual host module, which translates commands between a protocol used by the host processor and a protocol used by the communications module. The communications module is also configured to automatically seek and join a network, and to discover and bind to services provided over the network.

摘要： A system for supplying AC power from a DC power source, such as a photovoltaic array is disclosed. The system includes a converter and an inverter coupled by a DC link. Control methods and systems are provided to maintain the DC source voltage and the DC link voltage below the open-circuit voltage of the DC power source. During steady state conditions, the DC source voltage and the DC link voltage are maintained below the open-circuit voltage of the DC power source by controlling the output of the inverter. The DC link voltage is temporarily adjusted to allow for higher DC link transients when the DC power source is first coupled or re-coupled to the system. During conditions when the inverter is decoupled from the system, the converter is controlled to maintain the DC link voltage below the open-circuit voltage of the DC power source.

摘要： The present invention broadly comprises an assembly for incrementally changing an axially fixable position, including an annular gripping element with at least one deformation segment, a glide push ring axially displaceable along a pilot element, and a wedge push ring axially displaceable along the pilot element. The gripping element is in contact with a circumference of the pilot element and the deformable segments are circumferentially deformable in response to a change in a gripping element diameter. The glide ring incrementally urges the gripping element in a first direction along the pilot element. The gripping element axially fixes responsive to force applied by the wedge ring in a second direction, opposite the first direction, along the pilot element. A surface between gripping element inner and outer circumferences forms a fixed angle with the pilot element despite changes in the inner or outer circumferences.
