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: 11944935Abstract: A gas detection purification device is disclosed and includes a main body, a purification unit, a gas guider, a gas detection module and a controlling-driving module. The main body includes an inlet, an outlet, an external socket and a gas-flow channel disposed between the inlet and the outlet. The purification unit is disposed in the gas-flow channel for filtering gas introduced through the gas-flow channel. The gas guider is disposed in the gas channel and located at a side of the purification unit. The gas is inhaled through the inlet, flows through the purification unit and is discharged out through the outlet. The gas detection module is plugged into or detached from the external socket. The controlling driving module is disposed within the main body and electrically connected to the gas guider to control the operation of the gas guider in an enabled state and a disabled state.Type: GrantFiled: December 2, 2020Date of Patent: April 2, 2024Assignee: MICROJET TECHNOLOGY CO., LTD.Inventors: Hao-Jan Mou, Yung-Lung Han, Chi-Feng Huang, Chang-Yen Tsai, Wei-Ming Lee, Tsung-I Lin

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: 10612060Abstract: Provided is a method of preparing a high-purity galactooligosaccharide composition by fermentation of a low-purity galactooligosaccharide mixture with a yeast strain, Kluyveromyces lactis ATCC 8585. The high-purity galactooligosaccharide composition includes at least 99% of galactooligosaccharides selected from the group consisting of galactotriose, galactotetrose, galactooligosaccharides with five or more sugar units, and combinations thereof and lower than 1% of monosaccharides and disaccharides. Also provided is a high-purity galactooligosaccharide composition and applications thereof in regulating blood glucose level and improving gut microbiota. For example, the high-purity galactooligosaccharide composition may be used to manufacture food products, beverages, health food products, nutritional supplements, and pharmaceutical compositions for patients or pets afflicted with diabetes mellitus or lactose intolerance.Type: GrantFiled: February 22, 2018Date of Patent: April 7, 2020Assignee: KING-PREBIOTICS BIOTECHNOLOGY (TW) CO., LTD.Inventors: Chang-Lung Tsai, Ping-Ju Tsai

Patent number: 5277563Abstract: A scroll compressor has a stationary scroll member and an orbiting scroll member which moves around the stationary scroll member to consecutively compress working fluid. A piston is provided to urge the orbiting scroll member to come close to the stationary scroll member. The piston is driven to urge the orbiting scroll member by compressed working fluid which is guided to enter an annular chamber communicating with compressed working fluid or working fluid being compressed. By this arrangement, the mechanical efficiency of the scroll compressor will be enhanced, and mixing of working fluid and lubricant is able to be reduced. Furthermore, the wobbling of the orbiting scroll member will also be diminished.Type: GrantFiled: August 10, 1992Date of Patent: January 11, 1994Assignee: Industrial Technology Research InstituteInventors: Kuo Wen-Jen, Tseng Wen-Ding, Yang Chih-Cheng, Chang Lung-Tsai

Patent number: 5252046Abstract: A scroll type compressor comprising a housing inside which a stationary scroll member and a frame are fixed to define a space therebetween large enough to receive therein an orbiting scroll member which inter-engages with the stationary scroll member to define therebetween a hermetical compression pocket into which the fluid to be compressed fills. An Oldham-coupling ring restricts the orbiting scroll member to orbit around the center of the stationary scroll wrap only. A back pressure chamber is in pressure connection with the compressed fluid through a lubricant for the compressor and also in fluid connection with an inlet of the fluid to be compressed through a capillary-like passage.Type: GrantFiled: July 31, 1992Date of Patent: October 12, 1993Assignee: Industrial Technology Research InstituteInventors: Tseng Wen-Ding, Liu Da-Chuan, Kuo Wen-Jen, Chang Lung-Tsai, Yang Chih-Cheng, Tarng Guang-Der, Lin Rui-Rung, Lin Bao-Yuang, Ho Jan-Shiew
