Publication number: 20240162313Abstract: A method for forming a high electron mobility transistor is disclosed. A mesa structure having a channel layer and a barrier layer is formed on a substrate. The mesa structure has two first edges extending along a first direction and two second edges extending along a second direction. A passivation layer is formed on the substrate and the mesa structure. A first opening and a plurality of second openings connected to a bottom surface of the first opening are formed and through the passivation layer, the barrier layer and a portion of the channel layer. In a top view, the first opening exposes the two first edges of the mesa structure without exposing the two second edges of the mesa structure. A metal layer is formed in the first opening and the second openings thereby forming a contact structure.Type: ApplicationFiled: January 18, 2024Publication date: May 16, 2024Applicant: UNITED MICROELECTRONICS CORP.Inventors: Chih-Tung Yeh, Chun-Liang Hou, Wen-Jung Liao, Chun-Ming Chang, Yi-Shan Hsu, Ruey-Chyr 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

Publication number: 20240069418Abstract: A focal length adjustment mechanism, adapted for adjusting a focal length adjustment device located in a housing of a projector. The focal length adjustment mechanism includes a knob and a first stroke adjustment member. The first stroke adjustment member is located in the housing and includes a first end and a second end opposite to each other and a first pivot located between the first end and the second end. The first end is connected to the focal length adjustment device. The knob is connected to the second end. The knob rotates to drive the first stroke adjustment member to rotate around the first pivot. A distance between the first pivot and the first end is less than a distance between the first pivot and the second end, such that a movement path of the first end is less than a movement path of the second end.Type: ApplicationFiled: April 19, 2023Publication date: February 29, 2024Applicant: Qisda CorporationInventors: Chin Fu Lee, Chun Ming Shen

Patent number: 9263009Abstract: The present disclosure illustrates a sound insulation electronic pad for a bass drum of a jazz drum set. The electronic pad is assembled with a drum frame of the bass drum of the jazz drum set by a support structure, and located between a drumhead of the bass drum and a drum pedal. The electronic pad does not contact with the drumhead of the bass drum. When the electronic pad is knocked by the drumstick and the drumhead of the bass drum is not knocked by the drumstick, the electronic pad and an external trigger module simulate an electronic drum sound of the bass drum and output the electronic drum sound via an output device such as earphones or a loudspeaker. Therefore, the electronic pad of the present disclosure can be used to remodel the bass drum of the jazz drum set as an electronic drum.Type: GrantFiled: February 17, 2015Date of Patent: February 16, 2016Inventor: Chun-Ming Lee
