Patent number: 11965522Abstract: An impeller includes a hub and a plurality of blades. The blades are arranged around the hub, and each blade includes a leading edge, a blade tip, a root portion, a trailing edge, a windward side and a leeward side. The windward side including a first turning point and a second turning point, a first vertical height difference is formed from the blade tip to the first turning point, and a second vertical height difference is formed from the first turning point to the second turning point, and the first vertical height difference is greater than the second vertical height difference. The impeller apparently reduces the noise.Type: GrantFiled: January 28, 2022Date of Patent: April 23, 2024Assignee: DELTA ELECTRONICS, INC.Inventors: Pei-Han Chiu, Chien-Ming Lee, Chung-Yuan Tsang, Chao-Fu Yang

Publication number: 20240114619Abstract: An electronic device including an electronic unit and a redistribution layer is disclosed. The electronic unit has connection pads. The redistribution layer is electrically connected to the electronic unit and includes a first insulating layer, a first metal layer and a second insulating layer. The first insulating layer is disposed on the electronic unit and has first openings disposed corresponding to the connection pads. The first metal layer is disposed on the first insulating layer and electrically connected to the electronic unit through the connection pads. The second insulating layer is disposed on the first metal layer. The first insulating layer includes first filler particles, and the second insulating layer includes second filler particles. The first filler particles have a first maximum particle size, the second filler particles have a second maximum particle size, and the second maximum particle size is greater than the first maximum particle size.Type: ApplicationFiled: December 2, 2022Publication date: April 4, 2024Applicant: InnoLux CorporationInventors: Cheng-Chi WANG, Chin-Ming HUANG, Chien-Feng LI, Chia-Lin YANG

Patent number: 8514181Abstract: A pressure sensitive and luminous keyboard includes at least one key, a pressure detecting circuit, an illumination module and a controlling unit. When one of the plural keys is depressed in response to a first pressure, the pressure detecting circuit generates a pressure-strength sensing voltage. According to the pressure-strength sensing voltage, the controlling unit will judge the strength of the first pressure and control the illumination module to emit either the first light beam or the second light beam.Type: GrantFiled: September 3, 2010Date of Patent: August 20, 2013Assignee: Primax Electronics Ltd.Inventors: Bin-Hui Huang, Chien-Ming Yang

Patent number: 8314352Abstract: A two-level pressure sensitive keyboard includes at least one key and a membrane switch circuit module. The membrane switch circuit module includes a first contact, a second contact, a first spacing layer for separating the first contact from the second contact, a third contact, a fourth contact, and a second spacing layer for separating the third contact from the fourth contact. The thickness of the second spacing layer is greater than that of the first spacing layer. When the key is depressed in response to the first pressure, the first contact and the second contact are electrically connected with each other to generate a first sensing signal. When the key is depressed in response to the second pressure, the first contact and the second contact are electrically connected with each other and the third contact and fourth contact are electrically connected with each other to generate a second sensing signal.Type: GrantFiled: September 3, 2010Date of Patent: November 20, 2012Assignee: Primax Electronics, Ltd.Inventors: Bin-Hui Huang, Chien-Ming Yang

Publication number: 20120019444Abstract: A keyboard with a mode-switching function is provided. The keyboard includes at least one key, a pressure sensing circuit, an illumination module, a mode-switching program and a controlling unit. The mode-switching program is executable to enable both the pressure sensing circuit and the illumination module, so that the keyboard is operated in a pressure sensitive and luminous mode. The pressure sensing circuit is used for detecting the pressure, and generating a corresponding pressure-strength sensing voltage in response to the pressure. According to the pressure-strength sensing voltage, the illumination module is controlled by the controlling unit to emit either a first light beam or a second light beam.Type: ApplicationFiled: September 3, 2010Publication date: January 26, 2012Applicant: PRIMAX ELECTRONICS LTD.Inventors: Bin-Hui Huang, Chien-Ming Yang
