Patent number: 11937932Abstract: An acute kidney injury predicting system and a method thereof are proposed. A processor reads the data to be tested, the detection data, the machine learning algorithm and the risk probability comparison table from a main memory. The processor trains the detection data according to the machine learning algorithm to generate an acute kidney injury prediction model, and inputs the data to be tested into the acute kidney injury prediction model to generate an acute kidney injury characteristic risk probability and a data sequence table. The data sequence table lists the data to be tested in sequence according to a proportion of each of the data to be tested in the acute kidney injury characteristics. The processor selects one of the medical treatment data from the risk probability comparison table according to the acute kidney injury characteristic risk probability.Type: GrantFiled: July 8, 2022Date of Patent: March 26, 2024Assignees: TAICHUNG VETERANS GENERAL HOSPITAL, TUNGHAI UNIVERSITYInventors: Chieh-Liang Wu, Chun-Te Huang, Cheng-Hsu Chen, Tsai-Jung Wang, Kai-Chih Pai, Chun-Ming Lai, Min-Shian Wang, Ruey-Kai Sheu, Lun-Chi Chen, Yan-Nan Lin, Chien-Lun Liao, Ta-Chun Hung, Chien-Chung Huang, Chia-Tien Hsu, Shang-Feng Tsai

Patent number: 11863071Abstract: A power converter having a smooth transition control mechanism is provided. An oscillator circuit outputs a clock signal. A control circuit receives the clock signal from the oscillator circuit and outputs a control signal based on the clock signal. A driver circuit outputs a high-side conduction signal and a low-side conduction signal according to the control signal. A high-side switch is turned on or off according to the high-side conduction signal from the driver circuit. A low-side switch is turned on or off according to the low-side conduction signal from the driver circuit. The oscillator circuit receives the high-side conduction signal from the driver circuit. The oscillator circuit, according to the high-side conduction signal, determines whether or not the clock signal outputted to the control circuit needs to be adjusted.Type: GrantFiled: February 14, 2022Date of Patent: January 2, 2024Assignee: ANPEC ELECTRONICS CORPORATIONInventors: Chien-Nan Chen, Fu-Chuan Chen

Patent number: 11349325Abstract: A pulse controlled charging method for higher temperature charging in addition to the current-reducing operation at ambient temperature. A specific software control strategy for these purposes is proposed, which can be divided into two parts, (a) two-stage charging current control at ambient temperature, which sets different current-limiting transient points for chargers with different outputs; (b) high-temperature pulse charging, which utilizes an internal NTC (Negative temperature coefficient) thermistor inside the charger to detect the internal temperature of the charger, if the temperature exceeds a pre-determined value, the charging process will be stopped for a period of time to avoid the temperature of the charger becoming too high.Type: GrantFiled: December 6, 2019Date of Patent: May 31, 2022Assignee: PHIHONG TECHNOLOGY CO., LTD.Inventors: Ming-Huang Hung, Mu-Hsun Chen, Chien-Nan Chen, Yu-Sheng Yeh, Po-Chi Hung

Publication number: 20220092332Abstract: Systems, methods, and non-transitory computer-readable media can provide at least one frame of a content item to a saliency prediction model, the saliency prediction model being trained to identify salient points of interest that appear in content items. Information describing at least a first salient point of interest that appears in the at least one frame can be obtained from the saliency prediction model. The first salient point of interest can be predicted to be of interest to users accessing the content item. A view-based projection can be applied to a region corresponding to the first salient point of interest, wherein the view-based projection enhances a quality in which the region is presented.Type: ApplicationFiled: October 25, 2021Publication date: March 24, 2022Inventors: Evgeny V.
