  • Publication number: 20260131661
    Abstract: A vehicle includes a high-voltage and a battery safety system configured to disconnect the high-voltage battery in response to an unsafe condition. The vehicle includes a first voltage domain with a corresponding voltage and ground plane, the battery safety system being in the first voltage domain. The vehicle includes a second voltage domain supplying power to components of the vehicle such as actuators, lights, sensors, or controllers. A first DCDC supplies power from the high-voltage battery to the first voltage domain and a second DCDC supplies power from the high-voltage battery to the second voltage domain. A backup DCDC supplies power from the second voltage domain to the first voltage domain in response to failure of the first DCDC. The first DCDC may also supply power to the second voltage domain. A capacitor in the second voltage domain may supply power to the battery safety system as well.

  • Publication number: 20260127915
    Abstract: Sleep state power consumption estimation for vehicles is provided. An electric vehicle can include an electronic control unit (ECU). The ECU can enter a sleep state responsive to the electric vehicle entering a sleep mode and enter a run state from the sleep state responsive to the electric vehicle exiting the sleep mode. The ECU can determine, based on a range loss estimation corresponding to an estimated power consumption during the sleep mode, a remaining rage estimation of the vehicle. In some implementations, the electric vehicle includes sensors, and the ECU can obtain sensor data indicating a power consumption measurement during the sleep mode of the electric vehicle, from which the remaining range estimation can be determined. In other implementations, the ECU can determine the remaining range estimation without active hardware monitoring based on a predetermined sleep state power consumption rate and a duration of the sleep mode.

  • Publication number: 20260050721
    Abstract: An integrated circuit (IC) design may be received by a first process. First reset domain crossing (RDC) analysis may be performed by the first process on the IC design to generate first RDC analysis results. A set of processes may be spawned by the first process, where a second process in the set of processes may read the first RDC analysis results, obtain information for an RDC scenario from the first process, perform second RDC analysis on the IC design based on the information for the RDC scenario to obtain second RDC analysis results, and send the second RDC analysis results to the first process. The second RDC analysis results received from the set of processes may be merged by the first process to obtain merged RDC analysis results.

  • Publication number: 20260030910
    Abstract: In a computer-implemented workflow, a submission of an asset localized for a first location is received. The asset may be intended for dissemination to a second location. A trained neural network is applied to the asset to determine a probability of recommending localization of the asset for the second location. This determination can be based on a plurality of features indicating contextual aspects of a document, which are identified in accordance with a plurality of transformations performed on the asset utilizing the trained neural network. Responsive to determining that the probability satisfies a condition, such as being a percentage above a threshold value, a recommendation is provided to exclude the asset from being localized to the second location.

  • Patent number: 12531429
    Abstract: An apparatus may include a DC to DC converter that converts a high voltage level from a battery pack to a relatively lower voltage level for various components of a vehicle. The DC to DC converter may provide an alternate power supply in addition to a battery that is separate from the battery pack. The battery pack and the DC to DC converter may be used to supply power, instead of the battery, during a sleep mode of a vehicle. Further, the DC to DC converter can supply power to float charge the battery, thus minimizing cycling of the battery. The DC to DC converter and the battery may provide a redundant, or backup, power source for a vehicle.
