  • Publication number: 20200363324
    Abstract: The present invention discloses a wavelength-modulable spectrum generator as well as a system and method for measuring concentration of a gas component based thereon. The wavelength-modulable spectrum generator includes a filter plate, a to-be-measured gas box and a light intensity receiving plate. A plate surface of the filter plate is encircled with N filter holes, and a filter lens with a specific refractive index is correspondingly fixedly arranged in each filter hole. A light source mounting position is fixed to a side of an in-light surface of the filter plate. After any light source is mounted at the light source mounting position, lights of the light source irradiate the filter lens. A rotation and deflection driving mechanism is connected with an out-light surface of the filter plate and drives the filter plate to rotate or deflect along the axis according to a preset angle.

  • Patent number: 10325535
    Abstract: A method for testing a display panel includes: applying a first level signal to a first sub-pixel and a third sub-pixel of a first pixel unit and applying a second level signal to a second sub-pixel of the first pixel unit; applying the second level signal to a first sub-pixel and a third sub-pixel of a second pixel unit and applying the first level signal to a second sub-pixel of the second pixel unit; and detecting a short circuit between adjacent sub-pixels. The first level signal has a voltage polarity opposite to a voltage polarity of the second level signal. Therefore, it is ensured that any two adjacent sub-pixels have opposite voltage polarities when the short circuit between adjacent sub-pixels of the display panel is detected. The method also provides improved testing abilities to detect an open circuit in a sub-pixel.

  • Publication number: 20160261714
    Abstract: Present invention refers to a method for defining the browser fetching order of web resources. The method comprises: receiving in an intermediate node an HTTP request, included in a first uniform resource locator, for a web resource sent by a web browser; assigning a priority level to the HTTP request by the intermediate node; encoding the priority level and the HTTP request in a second uniform resource locator; and sending the second uniform resource locator as an HTTP-redirection response to the web browser, so the fetching order is defined. Present invention also refers to a system for defining the browser fetching order of web resources characterized by an intermediate node configured for redirecting the HTTP request to the web browser before letting the HTTP request reach the HTTP server, being the intermediate node configured for perform the previous steps.
