  • Patent number: 10748744
    Abstract: A method for exposing a pattern in an area on a surface using a charged particle beam system is disclosed and includes inputting an original set of exposure information for the area and inputting a target post-proximity effect correction (PEC) maximum dose. A local pattern density is calculated for the area of the pattern based on the original set of exposure information. A pre-PEC maximum dose is determined for the area. The original set of exposure information is modified with the pre-PEC maximum dose.

  • Patent number: 10731630
    Abstract: A control method for increasing reactive power generation of a wind turbine having a Doubly-Fed Induction Generator (DFIG) includes obtaining, by a control device having one or more processors and one or more memory devices, wind forecast data of the wind turbine. Further, the method includes generating, by the control device, a real-time thermal model of the DFIG of the wind turbine using the wind forecast data. More specifically, the thermal model defines a thermal capacity for the DFIG that does not exceed system limits. Thus, the method also includes dynamically adjusting, by the control device, a reactive power set point of the DFIG of the wind turbine based on the real-time thermal model.

  • Patent number: 10725383
    Abstract: Methods include inputting an array of pixels, where each pixel in the array of pixels has a pixel dose. The array of pixels represents dosage on a surface to be exposed with a plurality of patterns, each pattern of the plurality of patterns having an edge. A target bias is input. An edge of a pattern in the plurality of patterns is identified. For each pixel which is in a neighborhood of the identified edge, a calculated pixel dose is calculated such that the identified edge is relocated by the target bias. The array of pixels with the calculated pixel doses is output. Systems for performing the methods are also disclosed.

  • Publication number: 20200220623
    Abstract: Techniques are described for configuring an optical network unit (ONU) in a pre-burst state prior to transitioning the ONU to a burst-on state. During the pre-burst state, a laser emitter of the ONU stabilizes to its wavelength, thereby reducing the impact of wavelength drift when the ONU transitions to the burst-on state.

  • Publication number: 20200073809
    Abstract: Systems, apparatuses, and methods related to memory systems and operation are described. A memory system may be coupled to a processor, which includes a memory controller. The memory controller may determine whether targeting of first data and second data by the processor to perform an operation results in processor-side cache misses. When targeting of the first data and the second data result in processor-side cache misses, the memory controller may determine a single memory access request that requests return of both the first data and the second data and instruct the processor to output the single memory access request to a memory system via one or more data buses coupled between the processor and the memory system to enable processing circuitry implemented in the processor to perform the operation based at least in part on the first data and the second data when returned from the memory system.

  • Patent number: 10570882
    Abstract: A control method for dynamically controlling active and reactive power capability of a wind farm includes obtaining one or more real-time operating parameters of each of the wind turbines. The method also includes obtaining one or more system limits of each of the wind turbines. Further, the method includes measuring at least one real-time wind condition at each of the wind turbines. Moreover, the method includes continuously calculating an overall maximum active power capability and an overall maximum reactive power capability for each of the wind turbines as a function of the real-time operating parameters, the system limits, and/or the real-time wind condition. Further, the method includes generating a generator capability curve for each of the wind turbines using the overall maximum active and reactive power capabilities and communicating the generator capability curves to a farm-level controller of the wind farm that can use the curves to maximize the instantaneous power output of the wind farm.

  • Patent number: 10460071
    Abstract: In some embodiments, data is received defining a plurality of shot groups that will be delivered by a charged particle beam writer during an overall time period, where a first shot group will be delivered onto a first designated area at a first time period. A temperature of the first designated area at a different time period is determined. In some embodiments, the different time period is when secondary effects of exposure from a second shot group are received at the first designated area. In some embodiments, transient temperatures of a target designated area are determined at time periods when exposure from a shot group is received. An effective temperature of the target area is determined, using the transient temperatures and applying a compensation factor based on an amount of exposure received during that time period. A shot in the target shot group is modified based on the effective temperature.
