  • Patent number: 11769908
    Abstract: Presented are new, earth-abundant lithium superionic conductors, Li3Y(PS4)2 and Li5PS4Cl2, that emerged from a comprehensive screening of the Li—P—S and Li-M-P—S chemical spaces. Both candidates are derived from the relatively unexplored quaternary silver thiophosphates. One key enabler of this discovery is the development of a first-of-its-kind high-throughput first principles screening approach that can exclude candidates unlikely to satisfy the stringent Li+ conductivity requirements using a minimum of computational resources. Both candidates are predicted to be synthesizable, and are electronically insulating. Systems and methods according to present principles enable new, all-solid-state rechargeable lithium-ion batteries.

  • Publication number: 20220223066
    Abstract: An English pronunciation assessment method includes: receiving an audio file including an English speech and a text transcript corresponding to the English speech; inputting audio signal to one or more acoustic models to obtain phonetic information of each phone in each word, wherein the one or more acoustic models are trained with speeches spoken by native speakers and further with speeches spoken by non-native speakers without labeling out mispronunciations, such that a pronunciation error is detected more accurately based on the obtained phonetic information; extracting time series features of each word; inputting the extracted time series features of each word, the obtained phonetic information of each phone in each word, and the audio signal included in the audio file to a lexical stress model to obtain misplaced lexical stress in each of words in the English speech with different number of syllables without expanding short words to cause input approximation.

  • Patent number: 7956827
    Abstract: A current driving apparatus and method using a pulse width modulation (PWM) technique to display a desired gray level for passive matrix organic light emitting diode (PMOLED) display applications is disclosed. The current driving circuit includes a memory, a logic and a segment driver. The memory stores a desired gray level, the logic comprises a counter and provides a predetermined bias time, and the segment driver provides a constant current to the PMOLED display based on the desired gray level and the predetermined bias time. The segment driver provides a constant current to the PMOLED display until the counter value reaches the desired gray level, and the counter is first counted zero for the predetermined bias time and then increments by one for every other cycle.

  • Patent number: 7911484
    Abstract: A source driver comprising a frame memory, a first line buffer, and a second line buffer. The frame memory stores bits of pixel values of an image. The first line buffer then sequentially latches the bits of the pixel values from the frame memory with a first address index. The second line buffer then sequentially latch the bits of the pixel values from the first line buffer with a second address index, which is different from the first address index, and writes the bits of the pixel values back to the frame memory, such that the image is scrolled. The present invention also provides a method of refreshing the frame memory in a source driver.
