  • Publication number: 20220224541
    Abstract: An incorrect transmission, of a record of data to a distributed ledger system, can be prevented. A first signal can be received. The first signal can include a first instruction to cause the record to be transmitted to the system. One or more items of information in the record can be determined. A delay of time to be elapsed, before a transmission of the record to the system, can be set in response to a receipt of the first signal and a determination of the one or more items. The transmission of the record to the system can be caused to occur after the delay has elapsed. The transmission of the record to the system can be prevented in response to a receipt of a second signal before the delay has elapsed. The second signal can include a second instruction that supersedes the first instruction.

  • Publication number: 20220222709
    Abstract: Providing a state of desired effects (SDES) simultaneously on one or more presentation devices using a system having one or more switchers, each switcher having a unique identification code, activation parameters that control when the switcher is operable to send activation signals, and one or more triggers. Each trigger has a trigger identification code associated with a set of one or more presentation devices or associated with another switcher and another trigger, and triggering criteria relating to an occurrence of a particular event. One method includes activating a first switcher, receiving, at the activated first switcher, event information indicative of the occurrence of a particular event, determining if the event information meets triggering criteria for a trigger of the first switcher, and in response to the event information meeting triggering criteria for a trigger of the first switcher, activating the trigger of the first switcher that meets the triggering criteria.

  • Publication number: 20220178315
    Abstract: An engine braking system includes engine braking actuators for adjusting exhaust valve timings to engine braking timings in a cylinder-number braking mode. The system further includes an engine braking controller coupled to a control switch that produces a request indicating a requested cylinder-number braking mode. The engine braking controller is structured to transition exhaust valves to the engine braking timings, determine a control term to adjust intake air pressure for varying a braking power of the engine, and to adjust geometry of an exhaust turbine based on the control term. An adjusted speed of a compressor rotated by the exhaust turbine provides a change to intake air pressure that adjusts the braking power of the engine. Different levels of braking power are provided within different cylinder-number braking modes.

  • Publication number: 20210397541
    Abstract: A system to detect and resolve conflicts between different experiments running on a website building system (WBS). The system includes at least one processor, a conflict resolver to check for interactions and conflicts between an experiment and at least one other existing experiment from a set of existing experiments in the WBS, when the experiment is set-up or integrated into the set of existing experiments. The conflict resolver either resolves the interactions and conflicts, or allows the interactions and conflicts to remain. The system also includes an experiment manager running on the at least one processor to manage and coordinate the experiment and the at least one other existing experiment when the experiment is running concurrently with the at least one other existing experiment, after set-up or integration of the experiment.
