Abstract: A DC power plant generating DC power from a variety of engines including a Stirling cycle engine. The DC power plant includes a relatively small start-up power source that is discontinued after the engine is running. A method for producing DC power for a load including starting up an engine using power supplied by a relatively small power supply supplemented by a capacitor bank, providing output from the engine to a generator, producing alternating current (AC) power by the generator, converting the AC power to direct current (DC) power, disabling output of the DC power during a first set of pre-selected conditions, limiting a rate of change of current of the DC power during a second set of pre-selected conditions, reducing conducted and radiated emissions of the DC power, disconnecting the DC power from the load under a third set of pre-selected conditions, and providing the DC power to the load.

Abstract: According to various aspects, exemplary embodiments are disclosed of systems and methods for dynamic configuration of wireless clients and infrastructure in wireless networks, to tune client performance. A network embodiment includes a wireless network infrastructure and a plurality of devices having clients integrated therewith and configured for wireless communication via the wireless infrastructure and for communication with a server. Each client may acquire data relevant to network conditions affecting performance by the client in the network, and may send the acquired data to the server. Based on the acquired data, the server sends instruction to one or more of the clients via the wireless infrastructure to adjust operating parameter(s) to tune client performance in the network.

Abstract: According to various aspects, exemplary embodiments are disclosed of systems and methods related to client managed soft handover and seamless link failover for wireless networks. In an exemplary embodiment, a wireless client includes a primary interface and a secondary interface. The primary interface is configured to connect to a wireless network via a first wireless network connection. The secondary interface is configured to connect to the wireless network via a second wireless network connection. The wireless client also includes a controller configured to maintain the first wireless network connection via the primary interface and the second network connection via the secondary interface substantially simultaneously.

Abstract: A channel sounding scheme is presented herein that relies on a combination of a first channel sounding procedure and a second channel sounding procedure. The first channel sounding technique is one that involves an exchange of dedicated channel sounding related signals to determine channel conditions between the first wireless communication device and the particular second wireless communication device. The second channel sounding technique is one in which channel conditions are implicitly discovered from any signals transmitted by the particular second wireless communication device to the first wireless communication device. A first wireless communication device computes updates to steering matrix information used for beamforming one or more signal streams to a particular second wireless communication device based on a combination of the first channel sounding technique and the second channel sounding technique.
