  • Patent number: 11449491
    Abstract: An incorrect copy of a record of data can be prevented from being transmitted to a distributed ledger system. A first file can be received and can include information, in audio or video form, with a description of a subject matter of the record of data and with an authorization to transmit the copy to the distributed ledger system. The first file can be sent to a device. A second file can be received from the device and can include information that confirms that the description of the subject matter, included in the first file, is correct, and that confirms that an entity, which controlled production of the first file, has permission to authorize causing the copy to be transmitted to the distributed ledger system. The correct copy can be caused, based on a receipt of the first and the second files, to be transmitted to the distributed ledger system.

  • Publication number: 20220274601
    Abstract: This document describes techniques, apparatuses, and systems for a grid-based road model with multiple layers. An example road-perception system generates a roadway grid representation that includes multiple cells. The road-perception system uses data from multiple information sources to generate a road model that includes multiple layers. Each layer represents a roadway attribute of each cell in the grid and includes one or more layer hypotheses. In this way, the described techniques and systems can provide an accurate and reliable road model and quantify uncertainty therein.

  • Publication number: 20220258738
    Abstract: This document describes techniques and systems to make determinations of lane-type and roadway hypotheses in a road model. The road-perception system can fuse various forms of evidence to determine lane-type hypotheses and respective belief masses associated with the lane-type hypotheses. The road-perception system the computes, using the belief masses, a belief parameter and a plausibility parameter associated with the lane-type hypotheses. One or more roadway hypotheses are then determined using the lane-type hypotheses. The road-perception system then uses the respective belief parameter and plausibility parameter associated with the lane-type hypotheses to compute a belief parameter and a plausibility parameter associated with the roadway hypotheses. In this way, the described techniques and systems can provide an accurate and reliable road model with quantified uncertainty.

  • 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: 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: 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.
