Abstract: Methods and systems are provided for an evaporative emission fuel (EVAP) system. In one example, a method for the EVAP system includes loading canisters in parallel sequentially during a refueling event. The method further includes switching loading from one canister to another in response to a fuel level during the refueling event.

Abstract: Methods and systems are provided for an evaporative emission fuel (EVAP) system. In one example, a method for the EVAP system includes adjusting a vapor flow path to a plurality of canisters based on a canister load and a vehicle shut-off event occurring. The method further including flowing vapors to a less loaded canister later than to a more loaded canister.

Abstract: Methods and systems are provided for an evaporative emissions control system for onboard refueling vapor recovery of a heavy duty vehicle. In one example, a method may include, in response to greater than a threshold change in a fuel level of a fuel tank fluidically coupled to at least two fuel vapor storage canisters of an evaporative emissions control system during a refueling event, performing a canister working capacity diagnostic on each of the at least two fuel vapor storage canisters by measuring an exhaust gas air-fuel ratio (AFR) while independently purging each of the at least two fuel vapor storage canisters. In this way, the working capacity of each fuel vapor storage canister may be separately assessed in order to more accurate identify degradation of the working capacity.

Abstract: One embodiment of the present disclosure is directed to a wearable electronic device. The wearable electronic device includes an enclosure having a sidewall with a button aperture defined therethrough, a display connected to the enclosure, and a processing element in communication with the display. The device also includes a sensing element in communication with the processing element and an input button at least partially received within the button aperture and in communication with the sensing element, the input button configured to receive two types of user inputs. During operation, the sensing element tracks movement of the input button to determine the two types of user inputs.

Abstract: System and method for synchronizing blockchain nodes by using snapshots.

Abstract: Methods and systems are provided for conducting an evaporative emissions test on a fuel system and an emissions control system in a vehicle. In one example, in response to an indication that a vehicle parking condition may result in the isolation of the fuel system from the emissions control system via the unintentional closing of fuel tank valves, a vehicle's active suspension system may be employed in order to level the vehicle a determined amount such that the fuel system isolation issues may be mitigated prior to an evaporative emissions test procedure. In this way, the entire fuel system and emissions control system may be diagnosed for potential undesired emissions, and potential violations of regulatory requirements for evaporative emissions testing may be reduced.

Abstract: A robotic arm assembly having an arm with at least one end effector pivotally connected to the end of the arm. The robotic arm assembly has a continuous belt driven by two motors. Manipulation of the speed and direction of the two motors controls the length of the arm and the tilt of the end effector. A third motor controls the tilt of the arm.

Abstract: Methods and systems are provided for improving efficiency of purging a fuel vapor storage canister included in an evaporative emissions control system of a vehicle. In one example, a method includes controlling a duty cycle of a canister purge valve to purge fuel vapors stored in a fuel vapor storage canister to an engine of the vehicle, and adjusting a flow rate at which the fuel vapors are purged to the engine independently of the duty cycle by controlling a magnitude of a voltage supplied to the canister purge valve during the purging.
