  • Patent number: 9023385
    Abstract: A method of treating a patient to improve liver functioning includes providing a drug composed of at least one of pharmaceutical 2-(4-morpholinoaniline)-6-cyclohexyl aminopurine and a pharmaceutically acceptable salt thereof; and administering the drug to the patient in a manner and dosage effective to improve liver functioning. The 2-(4-morpholinoaniline)-6-cyclohexyl aminopurine can inhibit the activated hepatic stellate cells from synthesizing and expressing collagens and other extracellular matrix proteins including MMPs and TIMPs, and so it can inhibit liver fibrosis. In the liver, it can inhibit collagen synthesis and expression, and therefore reverse and treat hepatitis and liver cirrhosis effectively.

  • Patent number: 9005999
    Abstract: Methods for chemical mechanical polishing (CMP) of semiconductor substrates, and more particularly to temperature control during such chemical mechanical polishing are provided. In one aspect, the method comprises polishing the substrate with a polishing surface during a polishing process to remove a portion of the conductive material, repeatedly monitoring a temperature of the polishing surface during the polishing process, and exposing the polishing surface to a rate quench process in response to the monitored temperature so as to achieve a target value for the monitored temperature during the polishing process.

  • Patent number: 8976262
    Abstract: Methods of connecting network-based cameras to video station such that the ownership between the network-based camera with the respective connected socket can be locked, such that at any time, each of the at least one socket can lock ownership of only one network-based camera, and receives video from the only one network-based camera with ownership locked by the respective socket. As the socket of the current invention can now engage into “locking” relationship with only one network-based camera with camera-identification tag acceptable to the video station, and preferably with the lock key, the chance of spoofing can be substantially reduced.

  • Publication number: 20150045395
    Abstract: This invention relates to methods of reversing and inhibiting liver fibrosis and hepatitis using a small indolinone molecule Hesperadin and related compounds. Methods of identifying such agents and using them to inhibit the expression of collagens and ECM proteins including MMPs and TIMPs in purified hepatic stellate cells are provided. In vivo data of Hesperadin in inhibiting induced collagen production are presented. This method of specifically targeting drugs to hepatic stellate cells in vivo, provides a novel therapy for liver diseases.

  • Patent number: 8930013
    Abstract: A method of controlling polishing includes polishing a substrate having a second layer overlying a first layer, detecting exposure of the first layer with an in-situ monitoring system, receiving an identification of a selected spectral feature and a characteristic of the selected spectral feature to monitor during polishing, measuring a sequence of spectra of light from the substrate while the substrate is being polished, determining a first value for the characteristic of the feature at the time that the first in-situ monitoring technique detects exposure of the first layer, adding an offset to the first value to generate a second value, and monitoring the characteristic of the feature and halting polishing when the characteristic of the feature is determined to reach the second value.

  • Patent number: 8833959
    Abstract: A display arrangement includes a decoration layer, a light source underneath the decoration layer, and a lens layer arranged between the decoration layer and the light source. The decoration layer includes at least one void formed in the shape of a character when viewed from above. The lens layer is at least semi-transparent to permit transmission of light from the light source through the void. An optical structure is arranged in alignment with the void and is adapted to reduce intensity of the light in a peripheral region of the void so as to reduce a halo effect. The decoration layer may be formed as an external layer of a key or a button of a portable electronic device, or an outer casing of a portable electronic device.

  • Publication number: 20140136685
    Abstract: Systems and methods which provide an adaptive unified performance management (AUPM) framework for interacting with disparate network elements using techniques adaptive to operational conditions to provide network performance adaptive root cause analysis (ARCA) are shown. An AUPM framework of embodiments of the invention implements a proxy based architecture in which a plurality of proxies are utilized to connect to and perform data communication with the disparate network elements. Centralized performance management is in communication with the proxies to obtain and unify network element data for performance monitoring, alarm reporting, and/or root cause analysis. The performance monitoring, alarm reporting, and root cause analysis provided by centralized performance management of embodiments herein implements adaptive cluster-based analysis to provide robust operation adapted to accommodate various operational scenarios, such as may include time varying conditions and learning based configuration.

  • Patent number: 8330639
    Abstract: A remote controller for toys includes a user interface which applies the low-cost capacitive sensing method with the remote controller. Users can touch and/or drag on a remote controller surface by fingers to remotely control the movement of R/C cars, planes, helicopters or a boat. The remote controller is essentially a flat faced unit and there is no need for protruding control sticks or pushbuttons. This controller is applicable to different types of remote control toys with digital proportional control on speed and steering control. The remote controller is a symmetric product design whereby the controller is easily operable with left and right hand conventions.

  • Publication number: 20120114036
    Abstract: The present invention relates to method and apparatus for multiview video coding. In particular, the present invention describes a disparity compensated prediction to exploit the inter-view correlation in multiview video coding by providing stretching, compression, and shearing (SCSH) disparity compensation to approximate the actual disparity effects in addition to the translational disparity. A sub-sampled block-matching disparity estimation technique is provided to implement the SCSH disparity compensation which makes use of the interpolated reference frames for subpixel motion and disparity estimation in conventional hybrid video coding structure.

  • Patent number: 8058181
    Abstract: The current invention provides methods for performing a cleaning process that provides greater cleaning efficiency with less damage to device structures. After etching and photoresist stripping, a first plasma clean is performed. The first plasma clean may comprise one or more steps. Following the first plasma clean, a first HO based clean is performed. The first HO based clean may be a de-ionized water rinse, a water vapor clean, or a plasma clean, where the plasma includes hydrogen and oxygen. Following the first HO based clean, a second plasma clean is performed, which may comprise one or more steps. A second HO based clean follows the second plasma clean, and may be a de-ionized water rinse, a water vapor clean, or a plasma clean, where the plasma includes hydrogen and oxygen. For plasma processes, an RF, generated plasma, a microwave generated plasma, an inductively coupled plasma, or combination may be used.

  • Patent number: 8055025
    Abstract: A motion estimation method uses a search start point and a plurality of search paths extending from the start point. The method finds an image point along the plurality of search paths that has a minimum comparison value with a reference image block. This image point with a minimum comparison value becomes the new search start point, with a plurality of new search paths extending from the new start point. The method then finds the image point along the plurality of new search paths that has a minimum comparison value with the reference image block. The cycle repeats until points on the search paths have comparison values higher than the start point.
