Publication number: 20210370541Abstract: An ultrasonic vibration assisted machining device is applied to a cutting tool and includes a vibrating component and a spinning component. The vibrating component includes a main body including a first end surface, a second end surface and a central axis. The vibrating component is configured to receive electrical power and generate a vibration with a vibrating frequency in the central axis direction according to the electrical power. The spinning component includes a first surface connected to the second end surface of the vibrating component. The area of the first surface is greater than that of the second end surface. The spinning component generates a spinning motion centered on the central axis according to the vibration with the vibrating frequency generated by the vibrating component. Wherein, the spinning component transmits the vibration and the spinning motion to the cutting tool.Type: ApplicationFiled: May 25, 2021Publication date: December 2, 2021Inventors: Yunn-Shiuan LIAO, Chao-Hsin WANG, Chang-Cheng KO

DISPLAY DEVICE AND BRIGHTNESS CONTROL METHOD CAPABLE OF REDUCING POWER CONSUMPTION OF DISPLAY DEVICE
Publication number: 20130169692Abstract: A display device includes a display panel, a backlight module, a driving circuit and a control unit. The driving circuit is electrically connected to the backlight module and used for providing a driving voltage for the backlight module. The control unit is electrically connected to the display panel and the driving circuit. The control unit controls the driving voltage to vary within a predetermined ratio range periodically so as to make a backlight brightness of the backlight module vary periodically in response to the driving voltage within the predetermined ratio range and controls a display parameter of the display panel to vary periodically according to the backlight brightness of the backlight module so as to compensate the backlight brightness of the backlight module. Accordingly, the invention can reduce power consumption of the backlight module effectively so as to reduce power consumption of the display device.Type: ApplicationFiled: March 27, 2012Publication date: July 4, 2013Inventor: Chao-Hsin Wang -

Publication number: 20100328243Abstract: The present invention discloses a MEMS scanning coordinate detection method and a touch panel thereof, wherein the touch panel comprises a light source module, a MEMS reflector, an image sensor, an image signal processor, and a coordinate calculator. When the laser light from the light source module is reflected by the MEMS reflector, the laser light is transformed into a scanning light beam. When the touch panel is touched by a pen or a finger, the scanning light beam is blocked and two inactive pixels are formed on the image sensor. The electronic signal is transmitted from the image signal processor and calculated by the coordinate calculator to determine the touch point position.Type: ApplicationFiled: June 25, 2010Publication date: December 30, 2010Applicant: E-PIN OPTICAL INDUSTRY CO., LTDInventors: Chao-Hsin Wang, Yung-Shan Lin, San-Woei Shyu
