Patent number: 11986763Abstract: A remote control system for gas detection and purification is disclosed and includes a remote control device, a gas detection module and a gas purification device. The remote control device includes a gas inlet and a gas outlet. The gas detection module is disposed in the remote control device and in communication with the gas outlet to detect the gas located in an indoor space. The gas detection module provides and outputs a gas detection datum, and the remote control device transmits an operation command via wireless transmission. The gas purification device is disposed in the indoor space and receives the operating instruction transmitted from the remote control device to be operated. When the gas purification device is under the activated state, the gas in the indoor space is purified, and the purification operation mode of the gas purification device is adjusted according to the first gas detection datum.Type: GrantFiled: November 30, 2020Date of Patent: May 21, 2024Assignee: MICROJET TECHNOLOGY CO., LTD.Inventors: Hao-Jan Mou, Yung-Lung Han, Chi-Feng Huang, Chun-Yi Kuo, Yang Ku, Chang-Yen Tsai, Wei-Ming Lee

Patent number: 11937903Abstract: A blood pressure device includes a first blood pressure measuring device, a second blood pressure measuring device, and a controller. The first blood pressure measuring device is to be worn on a first position of a wrist so as to obtain a first blood pressure information of the first position. The second blood pressure measuring device is to be worn on a second position of the wrist so as to obtain a second blood pressure information of the second position. The controller is electrically coupled to the first blood pressure measuring device and the second blood pressure measuring device so as to adjust tightness between the expanders and the user's skin, respectively. The controller receives, processes, and calculates a pulse transit time between the first blood pressure information and the second blood pressure information, and the controller obtains at least one blood pressure value based on the pulse transit time.Type: GrantFiled: December 29, 2020Date of Patent: March 26, 2024Assignee: MICROJET TECHNOLOGY CO., LTD.Inventors: Hao-Jan Mou, Yung-Lung Han, Chi-Feng Huang, Chang-Yen Tsai, Wei-Ming Lee, Chun-Yi Kuo, Chin-Wen Hsieh

Patent number: 9018934Abstract: A low voltage bandgap reference circuit includes a positive temperature coefficient circuit unit, a negative temperature coefficient circuit unit and a load unit, wherein the positive temperature coefficient circuit unit comprises a first differential operational amplifier, a first, second and third transistor, a first resistor, a first and second diode, and the negative temperature coefficient circuit unit includes a second differential operational amplifier, a fourth, fifth and sixth transistor, a second resistor and a third diode. The low voltage bandgap reference circuit provides a current having a positive temperature coefficient characteristics and a current having a negative temperature coefficient characteristics to flow through the load in order to generate a stable reference voltage less affected by the temperature. Therefore, it avoids the problems of the low voltage bandgap reference circuit that can not be activated at low voltage.Type: GrantFiled: March 20, 2013Date of Patent: April 28, 2015Assignee: Integrated Circuit Solution Inc.Inventors: Ching-Hung Chang, Chun-Lung Kuo, Ching-Tang Wu, Chung-Cheng Wu, Chung-Hao Chen

Publication number: 20140337547Abstract: A high-speed data transmission structure includes first and second electronic units and an input/output bus. The input/output bus is electrically connected to the first and second electronic units, and includes a clock signal line and N data lines, where N is an even integer. The data lines are divided into first and second data signal line groups, each provided with the same number of data lines. In a transmit mode, the first electronic unit generates and transmits a clock signal to the clock data line, and generates output signals at each clock period of the clock signal. The output signals consist of N/2 data signals lasting for two clock periods of the clock signal, and the first and second data signal line groups alternatively receive the output signals. The second electronic unit simultaneously performs a receive mode to fetch and latch the data signals according to the clock signal.Type: ApplicationFiled: July 17, 2013Publication date: November 13, 2014Applicant: Integrated Circuit Solution Inc.Inventors: CHUNG-CHENG WU, CHUN-LUNG KUO, CHING-TANG WU, CHING-HUNG CHANG, YU-SHEN HSIEH, CHIA-WEI HO
