Abstract: An aftertreatment system comprises an aftertreatment component structured to decompose constituents of an exhaust gas produced by an engine. A reductant insertion assembly is fluidly coupled to the aftertreatment component and configured to insert a reductant therein. A controller is operatively coupled to the reductant insertion assembly and configured to instruct the reductant insertion assembly to insert the reductant into the aftertreatment component for a first insertion time between first time intervals. The controller determines an operating condition of the engine, and determines if the operating condition satisfies a predetermined condition. In response to the predetermined condition being satisfied, the controller instructs the reductant insertion assembly to insert the reductant into the aftertreatment component for a second insertion time between second time intervals. The second insertion time is longer than the first insertion time.

Abstract: A method and an apparatus pertaining to power-save operations for the apparatus may involve a processor of the apparatus transmitting, via a transmitter of the apparatus, a power-save request to one or more communication devices associated with the apparatus. The processor may receive, via a receiver of the apparatus, an acknowledgment from each of the one or more communication devices. The processor may cause the apparatus to enter a power-save mode in response to receiving the acknowledgment from each of the one or more communication devices.

Abstract: Systems and methods disclosed select and display icons corresponding to topics of digital documents. In particular, in one or more embodiments, systems and methods identify similar clusters of documents from a plurality of documents and generate icons for each identified cluster of documents. For instance, systems and methods identify topical phrases from identified clusters and utilize the topical phrases to identify icons corresponding to the topical phrases. More specifically, one or more embodiments include systems and methods that generate generalized terms from topical phrases utilizing a concept taxonomy and then identify icons by comparing the generated generalized terms to tags corresponding to a plurality of icons.

Abstract: Methods and apparatus for control access to memory in dual-processor. In particular, there are disclosed methods and apparatus for use where a single memory is shared for instructions for the processors and a data store to reduce conflicts between access requirements.

Abstract: An SCR system may include a controller configured to diagnose errors with a dosing system. The controller may control a pump to compensate for a loss in pressure when dosing reductant and may maintain the pressure as close to a target pressure by modifying a parameter affecting the operation of the pump. The modification of the parameter may be used to determine an estimated flow feedback. The controller may use the estimated flow feedback data and commanded dosing amount data to calculate a percentage error in response to and using an integrated commanded flow and an integrated estimated flow feedback to detect errors of the dosing system. The errors may include an injector stuck closed error, a blocked pressure line error, a partial blockage of a pressure line or injector error, an injector stuck open error, a disconnected pressure line error, a leakage of a pressure line or injector error.
