Publication number: 20240068124Abstract: An apparatus for producing silicon carbide crystal is provided and includes a composite structure formed by a plurality of graphite layers and silicon carbide seed crystals, wherein a density or thickness of each layer of graphite is gradually adjusted to reduce a difference of a thermal expansion coefficient and Young's modulus between the graphite layers and silicon carbide. The composite structure can be stabilized on a top portion or an upper cover of a crucible made of graphite, thereby preventing the silicon carbide crystal from falling off.Type: ApplicationFiled: August 23, 2023Publication date: February 29, 2024Inventors: CHIH-LUNG LIN, PO-FEI YANG, CHIE-SHENG LIU, CHUNG-HAO LIN, HSIN-CHEN YEH, HAO-WEN WU

Publication number: 20210077283Abstract: An implantable frame comprises a plurality of corner structures configured to decrease pressure to the vessel wall and define pulsatility enhancing windows of the implantable frame. The corner structures may comprise plurality of neighboring longitudinal struts that extend in a longitudinal direction of the blood vessel when placed to form the vessel wall to a substantially polygonal cross-section and distribute pressure loading of the corner structure among the plurality of neighboring longitudinal struts to improve biocompatibility. The corner structures also allow increased forming of the vessel wall and can provide stretching of the vessel wall to enhance pulsatility of the vessel wall.Type: ApplicationFiled: August 28, 2020Publication date: March 18, 2021Inventors: Chung Hao Yeh, Jennifer Gong, Brent Seybold, Christopher Ken, Suji Shetty, Edward F.

Patent number: 9539129Abstract: An apparatus for deploying and retrieving a self-expanding intravascular stent includes an intravascular delivery wire and floating marker band movably retained over the intravascular stent delivery wire and releasably mounting the self-expanding intravascular stent. The floating marker band is movably retained to a fixed marker band, and a distance between the fixed marker band and the floating marker band is variable and self-adjusting. One or more struts of the self-expanding intravascular stent are releasably constrained between a catheter wall and one or more sides of the floating marker band.Type: GrantFiled: March 21, 2014Date of Patent: January 10, 2017Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Eugene Young, Chung Hao Yeh, Christopher G. M. Ken, Thu Anh Ho

Patent number: 8174500Abstract: A temperature controlled mouse includes a central controller, a driver control circuit, a temperature control circuit, and a signal transmitting circuit. The driver control circuit generates coordinate control signals and pointer clicking signals, and the signals are transmitted to a host computer coupled to the mouse via the signal transmitting circuit. The temperature control circuit detects the changes of the temperature from a user's hand and thereby generates temperature control signals. The central controller controls the operation status of the mouse according to the temperature control signals, wherein when the temperature detected is within a predetermined temperature range, the central controller wakes the mouse and allows the transmission of signals from the mouse to the host computer; otherwise the central controller stops the transmission of signals. The temperature controlled mouse prevents accidental activation due to negligent bump.Type: GrantFiled: April 16, 2009Date of Patent: May 8, 2012Assignees: Silitek Electronic (Guangzhou) Co., Ltd., Lite-On Technology CorporationInventors: Yi-Ping Hsu, Tao-Cheng Yen, Er-Hao Chen, Chung-Hao Yeh

Publication number: 20100164388Abstract: A luminous system with a changeable color light applicable to an electronic device is provided. The system includes a light emitter for emitting a first light to outside of the electronic device, a color sensor for receiving a second light that is the reflection of the first light from an object and generating a RGB signal, and a central controller for receiving the RGB signal and generating a backlight color adjusting signal according to the RGB signal received. A backlight driver module of the device is further introduced to drive a backlight module to emit a third light according to the adjusting signal. The color of the third light is particularly the same as the second light. Thus the backlight color of the electronic device changes as what the color of the object is. The visual effect of the product can be alternative by providing this changeable color light.Type: ApplicationFiled: May 26, 2009Publication date: July 1, 2010Applicants: SILITEK ELECTRONIC (GUANGZHOU) CO., LTD., LITE-ON TECHONOLGY CORPORATIONInventors: Er-Hao CHEN, Tao-Cheng Yen, Yi-Ping Hsu, Chung-Hao Yeh
