Abstract: Provided is a voice assistance system with proactive routines that couples a remote server and respective user voice interactive devices to deliver a complete experience to the end user of the device. The voice assistance system can also provide a platform to connect remote users to customize commands (e.g., proactive or reactive) to improve day-to-day operation across groups of devices and/or users. For example, routines can be built for an organization and made available to voice interactive devices distributed by or on behalf of the organization. Administrators can select features for the device and pre-configure voice assistance devices with groups of pre-selected routines to deliver a device that is ready to go out of the box. Updates to a device or routines can be based on such groups. Additionally, primary routine instances can be linked to groups where changes to the primary instance are propagated to any linked users.

Abstract: Provided is a voice assistance system with proactive routines that couples a remote server and respective user voice interactive devices to deliver a complete experience to the end user of the device. The user devices can be managed by groups and/or associated entities who manage voice services for their users. For example, the entities can provide pre-configured voice routines that perform actions on behalf of their users. The voice assistance system can also allow users to customize these routines to improve day to day operation. In addition, external services and/or providers can be linked to the system and allowed to define routines that have external system dependencies. Avoiding and managing conflicts in this environment becomes quite challenging. Some approaches use execution queues and priority, others invoke time slices and limitations on assignment of routines to time slices to resolve these issues, among other examples.

Abstract: A superconductor device includes a high superconductivity transition temperature enhanced from the raw material transition temperature. The superconductor device includes a matrix material and a core material. The enhancing matrix material and the core material together create a system of strongly coupled carriers. A plurality of low-dimensional conductive features can be embedded in the matrix. The low-dimensional conductive features (e.g., nanowires or nanoparticles) can be conductors or superconductors. An interaction between electrons of the low-dimensional conductive features and the enhancing matrix material can promote excitations that increase a superconductivity transition temperature of the superconductor device.

Abstract: A system according to the principles of the present disclosure includes a stop-start module and a fuel control module. The stop-start module stops an engine and thereby interrupts an engine cycle when a driver depresses a brake pedal while an ignition system is on and the engine is idling. The stop-start module restarts the engine when the driver releases the brake pedal. The fuel control module, when the engine is restarted, selectively injects fuel into a cylinder of the engine as the cylinder completes the interrupted engine cycle based on an amount of crankshaft rotation corresponding to a difference between a position of a piston in the cylinder when the piston is stopped and top dead center.

Abstract: A system includes a mode module and an energy module. The mode module generates a mode signal based on a temperature of an engine and at least one of a deceleration signal and a regenerative braking signal. The energy module, based on the mode signal, increases cooling of a coolant of the engine during at least one of a deceleration event of a vehicle and a regenerative braking event. The energy module, while increasing the cooling of the coolant, supplies an overvoltage to a cooling pump of the engine.

Abstract: An auto ignition mitigation system comprises a piston position module that determines a position of a piston within a cylinder and a temperature module that determines a first temperature of air within the cylinder. A fuel enrichment module communicates with the piston position module and the temperature module and determines a first fuel quantity based on the first temperature and the position of the piston. A fuel control module communicates with the fuel enrichment module and provides the first fuel quantity to the cylinder after the engine is started and before a first exhaust stroke of the piston.

Abstract: A system includes a heat exchanger and a fluid flow control module. The heat exchanger includes a substrate, a catalyst applied to the substrate, and fluid passages.

Each of the exhaust channels and each of the fluid channels includes a respective ones of the partitioning members.

Abstract: A control system includes a heater control module and a particulate matter (PM) load module. The heater control module selectively activates an electric heater to initiate regeneration in a zone of a particulate filter and deactivates the electric heater after the regeneration is initiated. The regeneration continues along a length of the particulate filter after the electric heater is deactivated. The PM load module determines a PM load based on an outlet temperature of the particulate filter after the regeneration is initiated.

Abstract: A system for a vehicle includes a conversion efficiency module, a threshold determination module, and a catalyst fault indication module. The conversion efficiency module generates an ozone conversion efficiency of a catalyst that converts ozone into oxygen based on a first amount of ozone in air measured upstream of the catalyst and a second amount of ozone in air measured downstream of the catalyst. The threshold determination module generates an efficiency threshold based on ambient humidity. The catalyst fault indication module selectively indicates that a fault is present in the catalyst when the ozone conversion efficiency is less than the efficiency threshold.

Abstract: A regeneration system for a filter that filters exhaust gas of an engine includes a soot loading determination module that determines soot accumulation in the filter.

Abstract: An engine control system comprises an actuator control module and a tertiary injection module. The actuator control module provides secondary air to an exhaust system when a catalyst light-off mode is enabled and provides first and second injections of fuel to a cylinder during each engine cycle while the catalyst light-off mode is enabled. The tertiary injection module selectively provides a third injection of fuel to the cylinder during an exhaust phase of each engine cycle while the catalyst light-off mode is enabled. The first, second, and third injections are each separated by a period of time.
