Abstract: The present invention provides an improved grid connected solar micro-inverter. The solar micro-inverter is provided with a single processor that performs both the functions for the control of the micro-inverter and runs the application program associated with it and implements a communication modem for connectivity to the grid or to the Internet cloud. The solar micro-inverter therefore needs only a single processor to perform both the micro-inverter control and modem communication functions, resulting in cheaper and smaller system implementation.

Abstract: The present invention envisions the use of a coherent signal to make up for lost or delayed samples to a modem. The modem contains a coherent phase buffer containing samples of at least a cycle of a coherent signal corresponding to an outgoing signal. When, for any reason, the samples for the outgoing signal are lost or delayed, the modem adaptively patches the outgoing signal with samples from the coherent phase buffer. The modem tracks the outgoing signal, and synchronizes a pointer into the coherent phase buffer outgoing signal. Thus, when the outgoing signal samples are delayed or lost, the modem may replace the invalid samples from the samples of the outgoing data signal with a patch of an appropriate sample or samples from the coherent phase buffer. As such, disruptions of the modem session associated with an incoherent signal during modem communications are avoided.

Abstract: A directory for a plurality of information items stored in an electronic memory device is not retained in a continuous error-free portion of memory. Instead the memory area of the device is divided into blocks, with each block being assigned to no more than one information item. Each block is required to have a "recoverable" portion of memory that need not be error-free but from which original data can be accurately read, with the assistance of an error correction algorithm, despite the presence of certain error(s). Directory data for a block are stored in such block, thereby markedly reducing the length of a continuous portion of memory needed to store the directory data.
