| 20080221868 | Digital universal language - A numeric, hierarchical knowledge classification system, (e.g., Dewey Decimal Classification (DDC)) of concepts, is used for universal annotation. For example, “game” (DDC=799) relates to hunting and “game” (DDC=794.105), to chess. The universal annotation may be combined with human-aided machine translation, so individuals can tag their documents in the source language, simultaneously specifying meanings in the source and target languages, exercising control over what is said in the target language. Multilingual communication, by e-mails, forums, blogs, Wikipedia and the like may proceed, with each participant working in his tongue and tagging his writing with universal concepts. Moreover, a Universal System of Expression (USE) is introduced, based on the universal concepts. USE documents may be generated as byproducts of human-aided machine translations between any two natural languages that recognize USE, for fully automatic translation to other languages, on demand, and libraries of USE documents may be formed. | 09-11-2008 |
| 20080306794 | Measurement of content placement effectiveness over web pages and like media - A system estimates the part of a current content page that is currently visible on a user screen. A movement detection unit detects movement of the content page within the user's browser, and an estimator infers whether a particular content item of interest is within the currently visible area. The movement detection unit in one version detects operating system directives to find out whether the user is scrolling etc through the page. Alternatively an identifiable point is placed on the content item and continual measurement is made between identifiable point in the content and a point in the currently visible area. The system is useful for providing statistical data about the effectiveness of advertisement placement within web pages. | 12-11-2008 |
| 20090099891 | MEASUREMENT OF CONTENT PLACEMENT EFFECTIVENESS OVER WEB PAGES AND LIKE MEDIA - A system estimates whether a page carrying content of interest is currently in focus on a user, computer. in addition the system may determine the part of a current content page that is currently visible on a user screen. A movement detection unit detects movement of the content page within the user's browser, and an estimator infers whether a particular content item of interest is within the currently visible area. The movement detection unit in one version detects operating system directives to find out whether the user is scrolling etc through the page.

| 20080237653 | Deep Implant Self-Aligned To Polysilicon Gate - A CMOS image sensor includes a pinned photodiode and a transfer gate that are formed using a thick mask that is self-aligned to at least one edge of the polysilicon gate structure to facilitate both the formation of a deep implant and to provide proper alignment between the photodiode implant and the gate. In one embodiment a drain side implant is formed concurrently with the deep n-type implant of the photodiode. After the deep implant, the mask is removed and a shallow p+ implant is formed to complete the photodiode. In another embodiment, the polysilicon is etched to define only a drain side edge, a shallow drain side implant is performed, and then a thick mask is provided and used to complete the gate structure, and is retained during the subsequent high energy implant. Alternatively, the high energy implant is performed prior to the shallow drain side implant. | 10-02-2008 |

| 20110300716 | METHOD OF IMPROVING FILM NON-UNIFORMITY AND THROUGHPUT - Methods, apparatus, and systems for depositing materials with gaseous precursors are provided. In certain implementations, the methods involve providing a wafer substrate to a chamber of an apparatus. The apparatus includes a showerhead to deliver a gas to the chamber, a volume, and an isolation valve between the volume and the showerhead. A gas is delivered the volume when the isolation valve is closed, pressurizing the volume. The isolation valve is opened to allow the gas to flow to the showerhead when the gas is being delivered to the volume. A material is formed on the wafer substrate using the gas. In some implementations, releasing the pressurized gas from the volume reduces the duration of time to develop a spatially uniform gas flow across the showerhead. | 12-08-2011 |
