Patent number: 9893765Abstract: Devices include a primary transmission system, and first and second duplicate (dummy or non-transmitting) transmission systems. The primary transmission system includes a primary transmitter circuit receiving a data signal, a primary transmission line connected to the primary transmitter circuit, and a primary receiver circuit connected to the primary transmission line. The first duplicate transmission system is connected to the primary transmitter circuit, and supplies a transmission timing control signal to the primary transmitter circuit. The primary transmitter circuit stops transmitting (e.g., stops reducing the voltage of the primary transmission line) when the transmission timing control signal is received. The second duplicate transmission system is connected to the primary receiver circuit, and supplies an output timing control signal to the primary receiver circuit, and the primary receiver circuit outputs the data signal when the output timing control signal is received.Type: GrantFiled: March 21, 2017Date of Patent: February 13, 2018Assignee: GLOBALFOUNDRIES INC.Inventors: Igor Arsovski, Xiaoli Hu, Wei Zhao, Chao Meng, Xiaoxiao Li

Patent number: 8667695Abstract: The present application provides a work head for a rotational brush cutter. The work head comprises an upper plate, a lower plate and a blade, the upper plate and the lower plate being fixedly coupled. The lower plate is circular and has a passage therethrough with a gear arranged in the passage. The blade has a body portion and a connection portion with the body portion able to be extended outside of the upper and lower plates. The through passage is designed so that the blade can be replaced without requiring the upper plate and lower plate to be disassembled. As a result, because the blade is not restricted by a narrow space between the upper plate and the main frame, the work head does not need to be removed from the brush cutter to replace the blade thereby saving time and effort.Type: GrantFiled: June 20, 2011Date of Patent: March 11, 2014Assignee: Chervon (HK) LimitedInventors: Toshinari Yamaoka, Fangjie Nie, Chao Meng
