Patent number: 10951182Abstract: A millimeter wave power amplifier device has multiple millimeter wave power amplifier circuits. Each millimeter wave power amplifier circuit includes a transistor, a first serial connection resonation unit, a second serial connection resonation unit, multiple first frequency band adjustment units and multiple second frequency band adjustment units. The transistor has a first end connected with an input end, a second end connected with a grounding end and a third end connected with an output end. Each of the first and second frequency band adjustment units has a switch member and two storage members. The switch member and the storage members of the first and second frequency band adjustment units are serially connected. The millimeter wave power amplifier device can achieve multi-frequency band adjustable effect to lower the cost.Type: GrantFiled: January 2, 2020Date of Patent: March 16, 2021Assignee: Keycore Technology Corp.Inventors: Wei-Cheng Lin, Shih-Hsiu Tseng, Chien-Jen Hsiao, Chung-Hsin Liu

Patent number: 10647171Abstract: An apparatus for tire pressure monitoring comprises a case, a gas nozzle unit movably connected to the outside of the case, and a structure for tire pressure monitoring which is received in a receiving space in the case. The structure for tire pressure monitoring comprises a main body, a signal processing unit, a sensing unit connected to the signal processing unit, and a power unit to provide power. The main body has a first part and a second part. The first part is disposed on a top side of the second part; the first and the second parts are not on the same plane. The signal processing unit and the sensing unit are disposed on one side of the first part and on the top side of the second part, respectively. The power unit is disposed on a bottom side of the second part.Type: GrantFiled: September 10, 2018Date of Patent: May 12, 2020Assignee: Keycore Technology Corp.Inventors: Po-Wei Chiu, Wei-Cheng Lin, Shih-Hsiu Tseng, Chien-Jen Hsiao

Patent number: 10381709Abstract: A multi-band antenna structure includes a substrate having a first wiring area located on one side surface thereof. The first wiring area has a first metal trace, a second metal trace and a connecting portion formed therein. The first and the second metal trace are respectively in an elongated spiral pattern; and the connecting portion is electrically connected at two opposite ends to the first and the second metal trace. The multi-band antenna structure can be directly integrated into electrical circuits on a circuit board to provide the advantages of reduced manufacturing cost and capable of transmitting or receiving multiple bands of signals.Type: GrantFiled: July 6, 2017Date of Patent: August 13, 2019Assignee: Keycore Technology Corp.Inventors: Yang-Te Liang, Po-Wei Chiu, Sheng-Ruei Hsu, Wei-Cheng Lin, Chien-Jen Hsiao, Shih-Hsiu Tseng

Patent number: 9904837Abstract: A touch device with fingerprint identification function includes a touch unit and a fingerprint identification unit. The touch unit has a touch section and a non-touch section. The non-touch section is disposed around the touch section in adjacency to the touch section. The fingerprint identification unit is disposed on the non-touch section of the touch unit. The fingerprint identification unit is integrated with the touch unit. Therefore, it is unnecessary to additionally form a perforation or a channel on the touch device for arranging the fingerprint identification unit as in the conventional touch device. In this case, the structural strength of the touch device will not be deteriorated. Also, the manufacturing cost can be lowered.Type: GrantFiled: December 3, 2015Date of Patent: February 27, 2018Assignee: Keycore Technology Corp.Inventors: Wei-Cheng Lin, Chien-Jen Hsiao, Shih-Hsiu Tseng

Patent number: 9652603Abstract: A fingerprint identification device is directly integrated with and formed on a touch panel, a color filter (CF), a thin-film transistor (TFT) or a liquid crystal module (LCM). The fingerprint identification device improves the shortcoming of the conventional fingerprint identification device that it is necessary to first manufacture the fingerprint identification device on a silicon wafer and then integrate the fingerprint identification device with another component. Moreover, the fingerprint identification device has much higher fingerprint identification precision.Type: GrantFiled: December 11, 2015Date of Patent: May 16, 2017Assignee: Keycore Technology Corp.Inventors: Wei-Cheng Lin, Chien-Jen Hsiao, Shih-Hsiu Tseng
