  • Publication number: 20250134987
    Abstract: The current disclosure includes coronavirus vaccines that protect against pathogenic coronavirus species, as well as their variants. In certain embodiments, SARS-CoV-2 variant specific and multivalent coronavirus vaccines are described. The vaccines typically include a modified mRNA which encodes at least one coronavirus derived immunogen, such as a spike protein or a fragment thereof. The mRNA can be encapsulated into lipid nanoparticles or other carriers and formulated as pharmaceutical compositions which can be used to generate an immune response to coronavirus in a subject. The vaccines can be used to elicit potent B and T cell responses against SARS-CoV-2 variants and to confer protective immunity against SARS-CoV-2, as well as other pathogenic coronavirus species such as SARS-CoV and/or MERS-CoV.

  • Publication number: 20250122148
    Abstract: Disclosed are a high-selectivity KCNQ4 potassium channel agonist of formula I, a preparation method therefor and the use thereof. The compound further improves the KCNQ4 agonistic activity, and is still free of KCNQ2 agonistic activity, thus having excellent KCNQ4/KCNQ2 selectivity. The high-selectivity KCNQ4 agonist overcomes the defect of poor selectivity of existing potassium channel agonists, the activity is relatively increased, and the toxicity is remarkably reduced. The agonist also has a simpler structure and lower product cost, thereby having a better development prospect.

  • Publication number: 20250115271
    Abstract: Planning, or path finding is one of many tasks performed by an autonomous vehicle (AV). Planning involves searching for and updating an optimal plan from a current pose to an end pose while avoiding obstacles. Planning can be particularly challenging in driving scenarios involving complex driving maneuvers, such as parking, making a U-turn, making a K-turn, etc. Searching for an optimal plan may take more time, e.g., a few seconds, in certain driving scenarios. Consumers of the plan may have a low tolerance for delay in receiving the optimal plan. A relay can be implemented to publish the latest plan to the consumers at a frequency. The relay can check whether the delay violates a dynamic threshold and raise an error accordingly. The searching process can be improved to reduce the delay in finding an optimal plan.

  • Patent number: 12253785
    Abstract: An aspect of the present disclosure is related to a method for measuring and controlling linear chirp level of ultrafast laser pulse. The method includes steps as follows. A carrier-envelope phase-chirp (CEP-chirp) relation which serve as a chirp monitor is extracted, in which the CEP-chirp relation is generated from an ultrafast laser pulse. A linear chirp level of a target pulse is measured in response to the CEP-chirp relation. According to the measuring with respect to the linear chirp level of the target pulse, a dispersion element which the ultrafast laser pulse passes through is varied to control and stabilize the linear chirp level of the target pulse.

  • Publication number: 20240416960
    Abstract: It may be desirable for a remote advisor to request an autonomous vehicle to relocate to a target relocation pose using a freespace planner that has fewer constraints than the structured planner that is used for normal driving. The autonomous vehicle planning stack can include a remote vehicle interface, which can serve as the application programming interface for remote requestors to request relocation of the autonomous vehicle. The remote vehicle interface may implement a relocation state machine to carry out different parts of a relocation session. A scenario manager may subscribe to the state of the relocation state machine. Based on the state, the scenario manager can request the freespace planner to generate an output plan for the target relocation pose and can orchestrate handoff between different motion planners to relocate the autonomous vehicle.

  • Publication number: 20240416952
    Abstract: It may be desirable for a remote advisor to request an AV to relocate to a target relocation pose. In some cases, reaching a target relocation pose may involve a multi-point maneuver. Ability to perform relocation that involves a multi-point maneuver offers flexibility for the AV to maneuver around double-parked vehicles, to avoid obstacles, to aid a reroute when a route becomes unnavigable, etc. To support relocation that involves performing multi-point maneuvers, the planning stack may be modified to include a motion planner that can generate output plans that involve the AV going forward and in reverse. Moreover, the vehicle control stack may publish vehicle controls information as feedback information to the motion planner and the remote requestor, so that the motion planner and the remote requestor can be informed of the state of the AV.

    Abstract: Systems and techniques are provided for using different planners for autonomous driving. An example method can include determining, based on sensor data from one or more sensors of an autonomous vehicle (AV), a maneuver to be performed by the AV according to one or more parameters that deviate from one or more restrictions of a first planner being used by the AV to navigate a scene; identifying a second planner of the AV that supports the one or more parameters that deviate from the one or more restrictions of the first planner; determining a state of the AV selected to trigger a switch from the first planner to the second planner; maneuvering the AV using the first planner until the state of the AV is satisfied; and in response to determining that the state of the AV is satisfied, autonomously switching from the first planner to the second planner.

  • Publication number: 20240230866
    Abstract: Misalignment of camera and light detection and ranging (LIDAR) sensors can impact operations performed by an autonomous vehicle (AV) stack. Misalignment, or deviation from initial alignment over time, can occur in pitch, yaw, and roll dimensions. To address alignment issues, AV sensors may be calibrated before the AV drives on roadways. Additionally, AV sensors may be routinely calibrated at a maintenance facility to detect deviations from initial alignment of the sensors. Offline calibration of AV sensors in maintenance facilities can be inefficient and can significantly increase overhead. Therefore, online calibration of AV sensor misalignment may alleviate some of these concerns. Additionally, online calibration of AV sensors enables efficient monitoring and effective calibration of AV sensor alignment for a whole fleet of AVs while the fleet is on the road.
