  • Publication number: 20230174861
    Abstract: Methods of making a multilayered semiconductor particle, which may be referred to as a quantum dot, are described. The methods include combining a first zinc-containing compound and a selenium-containing compound to form a ZnSe mixture. The zinc-containing compound and the selenium-containing compound are rapidly combined in less than or about 5 seconds. The methods also include adding a tellurium-containing compound to the ZnSe mixture to form at least one ZnSeTe particle in a ZnSeTe mixture. The methods still further include forming a first shell layer on the ZnSeTe particle and forming a second shell layer on the first shell layer to make the multilayered semiconductor particle. In additional embodiments, the reactant and particle mixtures may be rapidly stirred. The light emitted by the multilayered semiconductor particles may be characterized by an enhanced narrowband emission profile (i.e., sharpness).

  • Patent number: 9898457
    Abstract: Examples for detecting and removing non-natural language within natural language to enhance performing content analysis on the natural language are provided herein. A plurality of terms is identified in a phrase, and a sliding window having a defined length is placed over a first sequence of terms from the plurality of terms. The first sequence of terms includes a first term, a second term, and a third term, the first term and the third term being adjacent to the second term. Based on the first term, the second term, and the third term, a determination is made as to whether the second term represents non-natural language. Upon determining that the second term is non-natural language, the second term is labeled as non-natural language and is removed from the plurality of terms based on determining the second term as non-natural language.

  • Publication number: 20050114785
    Abstract: Active Content Wizards (ACWS) related to helping computer users perform tasks are executed using an ACW interpreter. In one aspect of the present invention, the interpreter provides multiple levels of user interaction for a given ACW script. In order to help focus the user's attention, various methods are used to increase the conspicuity of the user interface elements relative to sub-tasks during execution of the ACW script. In one embodiment, areas around the user interface element are also de-emphasized.

  • Publication number: 20050033713
    Abstract: A text generator automatically generating a text document based on the actions of an author on a user interface. To generate the text document the author activates a recording component. The recording component records the author's actions on the user interface. Based on the recorded actions, a text generation component searches a text database and identifies an entry that matches the author's recorded actions. This text is then combined to form a text document, which provides instruction or other information to a user. During the process of generating the text document, the text can be edited using an editor as desired, such as to enhance the comprehensibility of the document.
