  • Patent number: 11978378
    Abstract: A display panel includes a first set of pixels that each include a respective red sub-pixel and a respective green sub-pixel and a second set of pixels that each include a respective blue sub-pixel and a respective green sub-pixel, where the first set of pixels and the second set of pixels are arranged on the display panel such that at least one side of each of the pixels in the first set of pixels is adjacent to at least one of the pixels in the second set of pixels, at least one side of each of the pixels in the first set of pixels is not adjacent to any pixel, and the green sub-pixels are arranged on the display panel such that the green sub-pixels are evenly distributed in the display panel.

  • Publication number: 20150169854
    Abstract: A method for authenticating identity of a user using keystrokes of the user includes receiving as input the keystrokes made by the user, extracting cognitive typing rhythm from the keystroke to provide features, wherein each of the features is a sequence of digraphs of a specific word, and providing active authentication using the features where the user is a legitimate user. A system for authenticating identity of a user using keystrokes of the user includes a plurality of stored profiles stored on a non-transitory computer readable medium, a sensor module for acquiring the keystrokes of the user to provide biometric data, a feature extraction module to process the biometric data and extract a feature set to represent the biometric data, a matching module to compare feature from the feature set with the stored profiles using a classifier to generate matching scores, a decision module configured to use the matching scores from multiple classifiers to verify a user's identity.

  • Patent number: 8737429
    Abstract: A method for use in a broadband wireless access protocol (such as IEEE 802.16 or Long Term Evolution (LTE)) includes scheduling by a base station a stand-by subscriber station for each subscriber station with uplink (UL) transmission opportunities, transmitting by the base station and over the network, a list of each of the stand-by subscriber stations, determining by the stand-by subscriber stations if there is unused bandwidth reserved for the corresponding subscriber station, communicating to the base station that there is the unused bandwidth, and releasing the unused bandwidth for use by the stand-by subscriber station.

  • Patent number: 6129108
    Abstract: A fluid delivering system receives a fluid from a supplying device, transfers the fluid to an operational device and then dumps the used fluid into an extraction device. The fluid delivering system has a main pipeline system and at least a secondary pipeline system. Each pipeline system uses a first flow valve to control the back flow of fluid to a first flow controller, a second flow valve to protect a pressure gauge and a third flow valve to control the flow of fluid to a pressure controller. Through the relative positioning and the concerted actions of these three valves, any malfunctioning in the fluid delivering system can be detected quickly so that on-going processing operation can stop immediately to minimize product damages.
