Patent number: 10718620Abstract: A navigation and positioning device including a storage, a mark feature analyzer, a first coordinate fusion component and a second coordinate fusion component is provided. The storage stores map information including a traffic mark feature and its mark coordinate. The mark feature analyzer is used for analyzing whether a captured image has the traffic mark feature. When the captured image has the traffic mark feature, the mark feature analyzer analyzes the traffic mark feature in the captured image and calculates a device coordinate according to the mark coordinate. The first coordinate fusion component fuses the device coordinate and a first fusion coordinate and uses fused coordinate as a second fusion coordinate. The second coordinate fusion component fuses the second fusion coordinate, traffic carrier inertial information and a global positioning coordinate and uses fused coordinate as an updated first fusion coordinate.Type: GrantFiled: December 21, 2017Date of Patent: July 21, 2020Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Ming-Xuan Wu, Yu-Yin Peng, Pin-Yung Chen, Che-Tsung Lin, Kang Li

Patent number: 9732721Abstract: A crankshaft rotating angle controlling method and a crankshaft rotating angle controlling system are provided. A shut-off signal is obtained, and an engine speed is judged. If the engine speed is lower than a specific value, a generator is set in a driving mode at an ending point of a missing tooth signal in a gear pulse signal, such that the generator in the driving mode drives a crankshaft to exceed a top-dead-center of a cylinder. When the crankshaft arrives at a bottom-dead-center of the cylinder, the generator is set to be in a holding mode of an error phase of a three-phase current. Through the generator in the driving mode, the given error phase of the three-phase current stops the generator immediately and the crankshaft is fixed within an angle range of a default stop position.Type: GrantFiled: August 26, 2015Date of Patent: August 15, 2017Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Pin-Yung Chen, Chin-Hone Lin, Wen-Yen Chen, Shin-Hsiang Chien, Ta-Chuan Liu

Patent number: 9300231Abstract: An output control apparatus of a motor includes a controller formed by having a power device to bridge a motor and a power supply. The controller incorporating the power device provides voltage control modulation during different motor speeds so as to fix the recharging voltage at the DC bus in a specific range without involvement of any voltage converter. It is unnecessary to use additional complex circuits or other DC/DC converters to reduce the voltage recharged from the motor running at a high speed. In addition, space for the apparatus is reduced, and the specification and function of the original controller can be maintained without trading off work in redesigning the motor system.Type: GrantFiled: March 6, 2014Date of Patent: March 29, 2016Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Shih-Hsiang Chien, Chin-Hone Lin, Hsieh-Tai Su, Pin-Yung Chen, Yung-Chen Wang
