In another embodiment, a power conversion system includes a controller to generate a drive signal to provide power control to a power path in response to a sense signal from the power path, where the sense signal is taken from other than the input of the power path, or the drive signal is applied to the power path at other than a first power stage. | 06-24-2010 |
20110055445 | Digital Signal Processing Systems - A signal processing system may include a multiply-accumulate (MAC) unit to generate output data by performing multiply-accumulate operations on first and second input data in response to a stream of MAC instruction words, where the MAC unit is pipelined to enable it to perform a multiply-accumulate operation in response to each MAC instruction word. The system may also include an instruction generator to generate the stream of MAC instruction words by performing loop expansion on a stream of intermediate instruction words, where one intermediate instruction word may comprise a group of fields to set up the MAC unit to execute in response to the one intermediate instruction word. | 03-03-2011 |
20120089409 | APPARATUS, METHOD, AND SYSTEM TO TRACK GOODS AND SERVICES - Embodiments herein describe an apparatus, method, and system to track goods and services. The tracked information is provided dynamically and in real-time to an end-user of the tracking system. The tracked information can be centrally managed by a server, or can be managed in a distributed network (e.g., cloud), or by a smart device (e.g., smart-phone, tablet PC). The method comprises: storing information in a database, the information corresponding to the good or service being tracked for an end-user; determining an update to the information stored in the database; determining whether a time attribute associated with the good or service exceeds a predetermined threshold; and generating an electronic message for the end-user of the good or service in response to determining the update or when the predetermined threshold exceeds the time attribute. | 04-12-2012 |
20150163074 | POWER-LINE COMMUNICATION COUPLING - In some embodiments, a system includes a power system coupled to a power bus, and a power line communication (PLC) gateway coupled in series with the power bus. In other embodiments, a system includes first and second power circuits coupled in series with a power bus, and first and second power-line communication circuits coupled in series with the power bus. In additional embodiments, a system includes a power converter coupled to a power bus and having one or more switching frequencies, and a power-line communication circuit coupled to the power bus and having one or more communication frequencies, where at least one of the switching frequencies is substantially greater than at least one of the communication frequencies. | 06-11-2015 |
20150194927 | FLASH TESTING OF PHOTOVOLTAIC MODULES WITH INTEGRATED ELECTRONICS - A method for testing a photovoltaic (PV) module having an integrated power converter includes: obtaining a reference output signature of a PV module design in response to a flash pattern; applying the flash pattern to a PV module under test; acquiring an observed output signature of the PV module under test in response to the flash pattern; and comparing the observed output signature of the PV module under test to the reference output signature. Second reference output and observed output signatures may be obtained in response to a second flash pattern. The output signatures may be combined using various techniques. One or more parameters of the integrated power converter may be preset to one or more predetermined states prior to applying a flash pattern. | 07-09-2015 |
