Abstract: A system for testing a ground fault detection system in an electric circuit establishes a ground connection between a bus and the ground via an inverter and a load by closing an inverter switch of the inverter and a grounding switch disposed between the load and the ground, determines whether the ground connection is detected, and determines a fault in the ground fault detection system responsive to the first ground connection not being detected by the ground fault detection system. Optionally, a ground fault may be identified by determining three phase voltages provided from each of plural inverters, determining symmetrical components of the three phase voltages for each of the inverters, and identifying a ground fault in one or more of the inverters while powered by the power supply based on the symmetrical components.

Abstract: In one example, a method for low-latency multimedia stream reception and output in a receiving device is described. Data packets may be extracted from a multimedia stream received over a network. The sequence of independently decodable units associated with the multimedia stream may be decoded. Each independently decodable unit may include one or more data packets. The sequence of decoded units may be stored in an output buffer. Further, flow of the decoded units from the output buffer to an output device may be controlled based on one of (a) a latency associated with the decoded units and (b) a rate of reception of the decoded units by the output buffer and a rate at which the output device is operating. The decoded units may be rendered on the output device.

Abstract: A method for media rate control in a video encoding system disclosed. In one embodiment, an optimal remaining one of the three parameter sets (Sk) is computed based on the provided user configuration inputs of two parameters sets (Si, Sj), wherein the user configuration inputs comprise two parameter sets (Si and Sj) out of three parameter sets (Si, Sj, and Sk), wherein the three parameter sets are latency parameter set, channel bandwidth parameter set, and video quality parameter set. The video encoding system is then configured based on the provided two parameter sets (Si, Sj) and the computed parameter set (Sk) to obtain a desired media rate control having optimal performance.

Abstract: A method for providing data channel virtualization between one or more devices and one or more applications is disclosed. In one example, a device policy manager (DPM) is initialized by creating an instance of the DPM before creating any application. Further, the DPM is configured for device management by identifying each device of the one or more devices and its associated device data channel (DDC) to be managed by the DPM. Each of the one or more devices is identified using an associated device identity (ID) and its corresponding DDC. Furthermore, one or more virtual data channels (VDCs) are created and provided to the one or more associated applications upon receiving a request from each of the one or more applications using a device identity (ID) and any application specific configuration parameters provided by the application.
