  • Patent number: 11923429
    Abstract: A semiconductor device and method for forming the semiconductor device are provided. In some embodiments, a semiconductor substrate comprises a device region. An isolation structure extends laterally in a closed path to demarcate the device region. A first source/drain region and a second source/drain region are in the device region and laterally spaced. A sidewall of the first source/drain region directly contacts the isolation structure at a first isolation structure sidewall, and remaining sidewalls of the first source/drain region are spaced from the isolation structure. A selectively-conductive channel is in the device region, and extends laterally from the first source/drain region to the second source/drain region. A plate comprises a central portion and a first peripheral portion. The central portion overlies the selectively-conductive channel, and the first peripheral portion protrudes from the central portion towards the first isolation structure sidewall.

  • Publication number: 20240059285
    Abstract: In various examples, techniques for using future trajectory predictions for adaptive cruise control (ACC) are described. For instance, a vehicle may determine a future path(s) of the vehicle and a future path(s) of an object(s). The vehicle may then use a speed profile(s) and the future path(s) to determine a trajectory(ies) for the vehicle. The vehicle may then select a trajectory, such as based on the future path(s) of the object(s). Based on the trajectory, ACC of the vehicle may cause the vehicle to navigate at a speed or a velocity. This way, the vehicle is able to continue using ACC even when the driver makes a maneuver(s) or the system determined to make a maneuver, such as switching lanes or choosing a lane when a road splits.

    Abstract: This application provides a hearing monitoring method and apparatus. The method includes: obtaining ear overuse information of a user, where the ear overuse information includes accumulated duration and/or accumulated times of overuse of ears of the user; and generating prompt information or a control instruction based on the ear overuse information. In this solution, because accumulated information is obtained, impact of a misoperation of the user can be excluded, and continued overuse of ears is also fully detected. Therefore, an unnecessary or missed reminder is avoided, thereby achieving more accurate hearing monitoring effect.
