  • Patent number: 11201621
    Abstract: A clock gating cell (CGC) is provided. The clock gating cell includes two latches that can be configured as a flip-flop to use positive/negative edges of a first clock signal to store a value of an input terminal, and the clock gating cell also includes a selector used for the flip-flop to select from values of different input terminals for storing. In addition, in a non-scan testing mode, the clock gating cell can forcefully close an unused latch through an independent signal, and in a scan shift duration and a scan capture duration of a scan testing mode, the clock gating cell can further forcefully output the first clock signal as the gating clock signal according to two independent signals.

  • Patent number: 11164676
    Abstract: A computer-aided recognition system for treatment response of rectal cancer is provided to predict the probability of a pathological complete response (pCR) of a rectal cancer patient after preoperative neoadjuvant chemoradiotherapy. The system includes a random forest model having several decision trees. Each decision tree has at least a feature node. Each feature node generates two branches according to a feature threshold, wherein each branch connects to another feature node or corresponds to an elementary pCR predicting probability. The random forest model integrates the elementary pCR probability of each decision tree, so as to generate a final pCR probability.

  • Patent number: 10896502
    Abstract: A prediction system of tumor image-aided prediction of prognosis for patients with uterine cervical cancer is provided. The prediction system includes a data augmentation module and a deep convolution neural network model. The data augmentation module is used to apply a data expansion process of the image data, so as to generate a plurality of slice sets of the uterine cervical cancer tumor. The deep convolution neural network model is used to apply a feature analysis to the slices, so as to predict the prognosis of a patient after chemoradiotherapy.

  • Patent number: 8957834
    Abstract: Timing controller with frequency modulation, converter with frequency modulation for scanning-based backlight unit module, and control system for 3D display. A timing controller with frequency modulation performs display frequency modulation of a first frame rate of a first display signal and outputs a second display signal at a second frame rate greater than or substantially equal to the first frame rate for presentation by a 3D display in a 3D mode or a 2D mode, selectively. A converter with frequency modulation performs scanning frequency modulation of a first scanning frequency of a first control signal generated from the converter and outputs a second control signal at a second scanning frequency greater than or substantially equal to the first scanning frequency, selectively, for controlling the scanning-based backlight unit module of the 3D display.

  • Patent number: 8928853
    Abstract: The present invention provides a method and system for repairing flat panel display, which repairing hot pixels of the flat panel display by femtosecond laser. The flat panel display comprises a LCD module and a color filter disposed on the top of the LCD module, wherein the surface of the color filter corresponding to the LCD module further has a color photoresist layer. The femtosecond laser is projected onto the color photoresist layer corresponding to the hot pixels such that a phenomenon of nonlinear multiple photons absorption can be occurred to change property of the color photoresist layer so as to transform the hot pixels into dead pixels.
