  • Patent number: 11789465
    Abstract: Certain examples of the present disclosure relate to systems and methods for controlling a vehicle. In particular, the present disclosure provides systems and methods for moving an aerial vehicle by decoupling the pitch- and roll-movement from thrust production. This decoupling can occur by shifting the center of gravity of the vehicle to create a moment about a desired axis. Some examples describe single-shaft rotary vehicles, while other examples describe coaxial rotary vehicles. The vehicles described herein may include a first mass moveable from a first position to a second position to create at least one of a rolling moment or a pitching moment to alter the direction of movement of the vehicle. A second mass may also be provided to alter the rolling moment or pitching moment. Methods for controlling the vehicles are also provided herein.

  • Publication number: 20230326790
    Abstract: Methods of filling features including metal and dielectric surfaces with conductive materials involve cleaning the metal surfaces with little or no damage to the dielectric surfaces. After cleaning, the feature may be exposed to one or more reactants to fill the feature with the conductive material in an atomic layer deposition (ALD) or chemical vapor deposition (CVD) process. Deposition may be selective or non-selective to the metal surface. In some embodiments, the filled feature is barrier-less, such that the conductive material directly contacts the metal and dielectric surfaces with no interposing barrier or adhesion layer.

  • Patent number: 11783032
    Abstract: Disclosed herein are systems and methods for identifying and mitigating Flush-based cache attacks. The systems and methods can include adding a zombie bit to a cache line. The zombie bit can be used to track the status of cache hits and misses to the flushed line. A line that is invalidated due to a Flush-Caused Invalidation can be marked as a zombie line by marking the zombie bit as valid. If another hit, or access request, is made to the cache line, data retrieved from memory can be analyzed to determine if the hit is benign or is a potential attack. If the retrieved data is the same as the cache data, then the line can be marked as a valid zombie line. Any subsequent hit to the valid zombie line can be marked as a potential attack. Hardware- and software-based mitigation protocols are also described.
