Patent number: 9045139Abstract: An intuitive eco-driving assistance system is mounted on a vehicle and has an input module, a control module and an output module. The control module is electrically connected to the input module and the output module. The output module acquires images ahead of the vehicle and speed signals for the control module to recognize a speed limit, traffic lights and a speed and distance of any obstacle on the images. Furthermore, according to the driving limits of the road and actual vehicle speed, the output module prompts for an eco-driving instruction and the speed limit meeting the road condition visually or audibly. Accordingly, the issue of conventional vehicles being structurally complicated and costly for conserving energy, only passively prompting fuel consumption, and consuming more fuel can be solved without requiring any additional and complicated system.Type: GrantFiled: December 20, 2012Date of Patent: June 2, 2015Assignee: AUTOMOTIVE RESEARCH & TESTING CENTERInventors: Yu-Sung Chen, Yi-Feng Su, Shung-Huang Chen, Yu-Long Chang, Chia-Hao Yang

Patent number: 7603095Abstract: The present invention provides a way of hysteretic switching for efficiently reducing the heavy switching between two adjacent coarse intervals. The present invention disposes a number of fine intervals to cover a range which is larger than the length of one coarse interval. Each coarse interval comprises some extra fine intervals which are exceeded the boundary of the coarse intervals in one side. The heavy switching will be postponed until the extra fine intervals are used up. In the meantime, the fine calibration unit records the number of extra fine interval which be used. An extra-boundary value will be recorded in the fine calibration unit for determining an initial fine interval in another coarse interval if the heavy switching occurs. It should be noted that the extra-boundary value could be a positive or minus value corresponding to which a forward coarse interval or a backward coarse interval the reference signal drifts into.Type: GrantFiled: February 17, 2006Date of Patent: October 13, 2009Assignee: Silicon Integrated Systems Corp.Inventors: Chia-hao Yang, Chia-jung Liu

Patent number: 7411429Abstract: A system for clock-switching applied in the field of integrated circuits is described. A phase interpolator converts an input clock signal into a clock_A and a clock_B having a phase difference therebetween and transmitting the clock_A and the clock_B. A switch command unit connected to the phase interpolator receives either the clock_A or the clock_B serving as a triggering signal for triggering the switch command unit to transform an input switching signal into an output switching signal when the output switching signal is located in either a rising or a falling edge. A selecting device connected to the phase interpolator and the switch command unit, selects either clock_A or clock_B according to the output switching signal from the switch command unit to output a clock-switching signal composed of clock_A and clock_B.Type: GrantFiled: October 28, 2005Date of Patent: August 12, 2008Assignee: Silicon Integrated Systems Corp.Inventors: Chia-hao Yang, Tze-hsiang Chao
