Publication number: 20070010338Abstract: A driving mechanism of baby rocking chair includes a transmission system having a transmission motor, a monitoring device, and a control circuit. When the rocking chair oscillates upward and approaches a predetermined set-up high point position that is affected by the gravitational force causing the slowing down of rotating speed, the monitoring device transmits a signal and provides the control circuit with the signal. As the rocking chair reaches the predetermined set-up high point position, the control circuit is capable of switching the direction of the rotation of the transmission motor. It is by this way of controlling the rotating shaft of oscillation of the rocking chair that the control circuit is capable of driving the rocking chair steadily.Type: ApplicationFiled: May 11, 2006Publication date: January 11, 2007Inventors: Tse-Chien Wu, Ho-Sheng Chen, Tsung-Yi Wu, Yi-Chen Chen, Hui-Ju Sun

Publication number: 20050071144Abstract: A method for modeling a memory with delay back annotation in accordance with the VITAL application specific integrated circuit modeling specification begins with modeling the memory with a timing generic and a port declaration. The wire delay of the memory is then modeled, followed by modeling a timing check for the memory. The wire delay of the model of the memory is then created. A description of the functional operation of the memory is then generated. The path delay for the address, control, and data bus signals to the memory is formed by overloading the VITAL path delay procedures. The VITAL timing check procedures are overloaded to determine timing constraint violations of the timing bus signals of the memory. The VITAL wire delay procedures are overloaded to determine interconnection delay bus signals of the memory.Type: ApplicationFiled: September 25, 2003Publication date: March 31, 2005Inventors: Nai-Yin Sung, Tsung-Yi Wu
