  • Patent number: 11968858
    Abstract: A top-emitting subpixel structure may include at least one bank structure defining a plurality of emissive areas, and an emissive structure located in each emissive area. The subpixel structure may have a subpixel length and a subpixel width less than the subpixel length, a ratio of the subpixel length to the subpixel width defining a subpixel aspect ratio. Each emissive area may have an emissive area length and an emissive area width shorter than the emissive area length, a ratio of the emissive area length to the emissive area width defining an emissive area aspect ratio. The subpixel length may define a primary axis when the subpixel aspect ratio is greater than the emissive area aspect ratio; otherwise, the emissive area length may define the primary axis. At least a majority of the emissive areas may be arranged successively widthwise along a secondary axis perpendicular to the primary axis.

  • Publication number: 20240095580
    Abstract: Herein is a universal anomaly threshold based on several labeled datasets and transformation of anomaly scores from one or more anomaly detectors. In an embodiment, a computer meta-learns from each anomaly detection algorithm and each labeled dataset as follows. A respective anomaly detector based on the anomaly detection algorithm is trained based on the dataset. The anomaly detector infers respective anomaly scores for tuples in the dataset. The following are ensured in the anomaly scores from the anomaly detector: i) regularity that an anomaly score of zero cannot indicate an anomaly and ii) normality that an inclusive range of zero to one contains the anomaly scores from the anomaly detector. A respective anomaly threshold is calculated for the anomaly scores from the anomaly detector. After all meta-learning, a universal anomaly threshold is calculated as an average of the anomaly thresholds. An anomaly is detected based on the universal anomaly threshold.

  • Publication number: 20230253185
    Abstract: An RF signal supply system for plasma generation includes an RF signal generator, an impedance matching system, and a control module. The RF signal generator includes a control system. The impedance matching system has an input connected to an output of the RF signal generator, an output connected to a plasma processing system, a gamma control capacitor, and a frequency control capacitor. The control module is connected in data communication with each of the RF signal generator and the impedance matching system. The control module is programmed to transmit control signals to the impedance matching system based on corresponding data received from the control system of the RF signal generator, where the control signals direct control of the gamma control capacitor and the frequency control capacitor. The control module is also programmed to transmit data received from the impedance matching system to the control system of the RF signal generator.

  • Patent number: 11556584
    Abstract: There is disclosed a system, apparatus and methods for optimizing photo selection. When a photographer takes photos as requested in a shot list, the photos are automatically assigned a quality score which correlates to how prominently the photo would be displayed in an online search. The photos and the quality scores are displayed to the photographer so that when the photographer has shot a sufficiently high quality photo then the photographer can stop shooting. Photos with the highest quality scores are optimal. The shot lists include reference photos, and if a new photo has a higher quality score than the corresponding reference photo, the new photo becomes the reference photo.

  • Patent number: 11440929
    Abstract: Described herein are cobalt compounds, processes for making cobalt compounds, cobalt compounds used as precursors for depositing cobalt-containing films (e.g., cobalt, cobalt oxide, cobalt nitride, cobalt silicide etc.); and cobalt films. Examples of cobalt precursor compounds are bis(diazadiene)cobalt compounds. Examples of surfaces for deposition of metal-containing films include, but are not limited to, metals, metal oxides, metal nitrides, and metal silicates; silicon, silicon oxide and silicon nitride. Alkylated diazadiene ligands are used to form cobalt complexes which are used for selective deposition on certain surfaces and/or superior film properties such as uniformity, continuity, and low resistance.

  • Patent number: 10911081
    Abstract: Systems and methods for reducing reflected towards a higher frequency radio frequency (RF) generator during a period of a lower frequency RF generator and for using a relationship to reduce reflected power are described. By tuning the higher frequency RF generator during the period of the lower frequency RF generator, precise control of the higher frequency RF generator is achieved for reducing power reflected towards the higher frequency RF generator. Moreover, by using the relationship to reduce the reflected power, time is saved during processing of a wafer.

  • Patent number: 10757532
    Abstract: There is disclosed herein a non-volatile machine-readable medium storing a program, a system and method for enabling proximity-based, peer-to-peer sharing of media in which a first device having a wireless communication surrounding the device detects other wireless devices within the region. Communication connections are formed between the wireless devices and a list of the authenticated connections is maintained. Without input from a user, media is shared between the individual devices on the authenticated connections list and a remote server, subject to permissions pre-set by the individual devices. Devices not included in the list of authenticated connections are blocked from accessing the media. Access to the media is available for a period of time, after which time access to the media is blocked for all devices.

  • Patent number: 10735299
    Abstract: Managing connections for execution of a client software application. A client software application is analyzed before execution of the application using code analysis and, optionally non-functional metadata analysis, of the application to determine one or more classifications of operations of the application. A mapping of application operation classifications to server characteristics suited to the application operation classifications is maintained. Multiple servers currently available to process at least a portion of the client software application may be monitored, and each of the multiple servers may be characterized according to their performance and resources. The classifications of operations of the analyzed application may be compared to the characteristics of the multiple servers currently available using the mapping, and a server may be selected based on the comparison.
