Publication number: 20240082160Abstract: An amlodipine dry suspension, comprising a diluent, a suspending aid, etc. and being free of surfactants. A preparation method therefor comprises the following steps: a) preparing an aqueous mixture 1 containing amlodipine besylate by using a high-speed homogenization method; b) adding sodium benzoate to the mixture 1, and homogenizing same at a high speed to obtain a mixture 2; and c) granulating the mixture 2 and other components, and then drying same. The raw materials are homogenized and mixed at a high speed, no surfactant is added during the preparation, amlodipine is fully wetted by using a high-speed homogenization process, prescription components are simplified, and the amlodipine dry suspension is more suitable for children to use. Compared with ultrasonic stirring, scaled-up and industrial production are easier to realize for the high-speed homogenization process, and at the same time, the preparation is good in stability and convenient to carry.Type: ApplicationFiled: December 31, 2021Publication date: March 14, 2024Inventors: Hanxiong Li, Xianzhu Wang, Weitang Chen, Yuan Chen, Ping Guo, Yongyi Wu, Yongmei Qin, Hongxue Huang, Li Wang

Patent number: 11105842Abstract: In described examples, a method of determining whether there is an open load fault in a test circuit includes closing a first switch to couple an input voltage to a first LC filter in which a first capacitor is coupled to a ground, the first LC filter coupled to a first terminal coupled to the test circuit; and closing a second switch to couple the input voltage to a second LC filter in which a second capacitor is coupled to the ground, the second LC filter coupled to a second terminal coupled to the test circuit. After the LC filters charge to the input voltage, the second switch is opened, and the second capacitor is discharged across a discharge resistor for a specified discharge time. The voltage across the discharge resistor falling below a reference voltage indicates that there is an open load fault in the test circuit.Type: GrantFiled: October 3, 2018Date of Patent: August 31, 2021Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: JianQuan Liao, GuangYao Zhou, Yuqing Yang, Yongyi Wu

Patent number: 8775192Abstract: A digital audio interface may include two signal inputs to transmit audio data. A first signal line may carry digital serial audio data. The second signal line may carry a word clock signal to differentiate the serial audio data transmitted over the first signal line. In the case of stereo audio data, the word clock signal may correspond to a left-right clock signal and may differentiate audio data intended for a right channel from that intended for a left channel. The audio data may also be differentiated differently depending on the configuration, such as in the case that the transmitted audio data include audio for more than two channels. The word clock signal may be scaled to regenerate a bit clock signal used to encode the serial audio data over the first signal line. The encoding bit clock signal need not be transmitted.Type: GrantFiled: June 8, 2011Date of Patent: July 8, 2014Assignee: Analog Devices, Inc.Inventors: Jie Fu, Yang Pan, Yongyi Wu, Khiem Quang Nguyen
