Patent number: 12267003Abstract: A power converter that properly copes with the wiring defects on a feedback path is shown. According to a control signal, a power driver couples an input voltage to an energy storage element to provide an output voltage that is down-converted from the input voltage. The output voltage is further converted into a feedback voltage by a feedback circuit, and is entered to an error amplifier with a reference voltage for generation of an amplified error. A control signal generator generates the control signal of the power driver according to the amplified error. The power converter specifically has a comparator, which is enabled in a soft-start stage till the output voltage reaches a stable status. The comparator compares the amplified error with a critical value. When the amplified error exceeds the critical value, the input voltage is disconnected from the energy storage element.Type: GrantFiled: December 22, 2022Date of Patent: April 1, 2025Assignee: RICHTEK TECHNOLOGY CORPORATIONInventors: Jung-Sheng Chen, Chih-Chun Chuang, Yong-Chin Lee

Patent number: 7141172Abstract: Distributed valve simulated moving beds are described in which junctions located between successive columns interrupt the flow of process fluid between columns, and either transmit the process fluid through a zone bypass to a succeeding column within the same zone or, if the junction is located between zones, direct the process fluid to an input/output line that is dedicated to the particular zone that immediately follows the junction. At each step of the SMB's operation, the distribution of flows in each junction is modulated to accomplish movement of ports consistent with the SMB's design. Further described are simulated moving beds that contain one or more decoupled on-line regeneration zones. The regeneration zone is decoupled from the separation zones in the sense that it observes a step time (a “regeneration interval”) that is different than the step time observed by the separation zones of the SMB.Type: GrantFiled: September 27, 2002Date of Patent: November 28, 2006Assignee: Purdue Research FoundationInventors: Nien-Hwa Linda Wang, Chim Yong Chin

Patent number: 6366649Abstract: A method for managing voice registration entries of voice recognition apparatus for use in both a handset and a hands-free kit. In the method, it is determined whether the handset is set to a hands-free mode where the handset is mounted on a cradle, thus connecting with the hands-free kit. If the handset is set to the hands-free mode, a voice registration entry for the handset is compared with a voice registration entry for the hands-free kit to calculate an entry difference value therebetween. A voice recognition process is performed, if the entry difference value is a minimum value, e.g., substantially zero. If the entry difference is larger than the minimum value, then a voice entry is registered for the hands-free kit, in response to a user confirmation. If the entry difference is smaller than the minimum value, then the voice entry is registered for the handset, in response to a user confirmation.Type: GrantFiled: August 13, 1998Date of Patent: April 2, 2002Assignee: Samsung Electronics Co., Ltd.Inventors: Kyung-Joon Chun, Seo-Yong Chin, Joung-Kyou Park
