Abstract: An auxiliary system with purge control automatically supplies diesel exhaust fluid (DEF) to an onboard DEF tank of a diesel engine to enable prolonged unattended operation. The system includes an auxiliary DEF tank, an auxiliary DEF supply line, a controller, a pump, an air inlet, and a three-way valve configured to switch the pump inlet between the auxiliary DEF tank and air. In response to low-level DEF, the pump delivers DEF through the supply line to replenish the onboard DEF tank. The controller may automatically calculate onboard DEF tank volume based on the delivered volume of DEF, and DEF level data received from an ECM, to enable replenishment control regardless of engine make and model. In response to high-level DEF, engine stoppage, or other system fault, the controller switches the valve to air and runs the pump for a predetermined time to purge DEF from the supply line.

The to processor may determine the ModCod using an ACM technique. For the plurality of terminals, the processor may dynamically determine aggregate bandwidth availability and congestion within the ACM technique to optimize sharing of available bandwidth.

Abstract: A single, multi-effect, energy harvesting and heat managing spun yarn and a manufacturing method thereof are provided. The spun yarn includes a combination of a configurable number of fibers selected from a fiber that absorbs, stores, and releases heat energy through a phase change; fibers that convert heat energy or ultraviolet radiation energy into far infrared radiation (FIR) energy and radiate the FIR energy to other fibers and to one or more body parts of a user wearing a garment created from the spun yarn; a fiber that absorbs moisture and generates heat energy through an exothermic reaction; a fiber that provides heat insulation and repels moisture; a fiber with elasticity; and a fiber that conducts heat and maintains a substantially uniform temperature within the fibers. One or more fibers are positioned in a sheath formed free of a core or with at least one core in the spun yarn.

Abstract: An Application Data Management System (ADMS) enables an application file system to be mounted at any selected reconstruction time (TR). If the reconstruction time TR falls intermediate snapshot creation timepoints, the ADMS creates a version of the application file system at the selected reconstruction time TR using a snapshot of the data file from a previous application file system snapshot creation timepoint, and a snapshot of the log file from a subsequent application file system snapshot creation timepoint. The ADMS uses the snapshot of the log file from the subsequent snapshot creation timepoint to replay transactions on the snapshot of the data file from the previous snapshot creation timepoint up to the selected reconstruction time TR. This enables the state of the application file system to be recreated and mounted at any arbitrary selected reconstruction time, even if the selected reconstruction time is not coincident with snapshot creation timepoints.
