Abstract: Embodiments described herein methods can be used in particulate filter regeneration, such as particulate filters used for filtering the exhaust of an engine, e.g., a diesel engine. Systems herein can be configured to dispense combustion gas(es) into housing were a particulate filter is contained and to ignite the combustion gases. Methods for conducting a safety verification process of such systems are disclosed, as well as methods for regenerating the filters. Still other embodiments are described.

Abstract: Disclosed are systems, computer-readable mediums, and methods for receiving an input/output operation regarding data associated with a distributed storage system that includes a plurality of storage devices. A key identifier associated with the I/O operation is determined. The key identifier identifies a key that has been divided into a number of key pieces. Two or more storage devices of the plurality of storage devices that contain one or more of the key pieces are determined and at least a threshold number of key pieces are requested from the two or more storage devices. The minimum number of key pieces needed to reconstruct the key is the threshold number. The key is reconstructed from the requested key pieces. A cryptographic function is performed on data associated with the I/O operation using the reconstructed key and the I/O operation is completed based upon the performed cryptographic function.

Abstract: A passive optical network is provided that integrates signals carrying broadcast CATV services into a FTTH/C network that also provides high-speed Internet access and telephony. Essentially all residential telecommunications services are provided in a single network, based on a single fiber and a single simple transceiver in an optical network unit. Multiple services (e.g., analog video, digital video, cable-modem based Internet access) are multiplexed using separate rf subcarriers (subcarrier multiplexing or SCM) and the delivered signals are compatible with existing consumer appliances (e.g., TVs, VCRs, cable modems, etc.).

Abstract: A method for regulating coolant flow rate to a heat exchanger in an automotive vehicle is described. The method includes the steps of providing a main fluid pump for providing a source of fluid under pressure to the vehicle engine and the heat exchanger and providing a reversible flow auxiliary pump between the main fluid pump and the heat exchanger. The method further includes the steps of generating an engine speed signal and an ambient temperature signal. The auxiliary pump forces fluid against the flow from the main fluid pump when the engine speed signal is greater than a threshold value and forces fluid to the heat exchanger when the ambient temperature signal is below a predetermined value and the engine speed signal is less than the threshold value and within predetermined values. A system is also disclosed for accomplishing the method.
