Publication number: 20250137461Abstract: An oscillating fan control system includes a holder, a stepper motor, a rotating shaft, a shaft encoder, and a controller. The controller is electrically coupled to the stepper motor and the shaft encoder. The shaft encoder can generate a status signal corresponding to a rotation path of the rotating shaft. The controller includes a reversing circuit and a driving circuit. The reversing circuit can generate a reversing signal for the stepper motor in response to the status signal indicating a deviation of the rotating shaft from a midpoint position of the rotation path. The driving circuit can generate pulse signals for the stepper motor according to a subdivision parameter and an oscillation angle. A method for controlling an oscillating fan is also disclosed.Type: ApplicationFiled: October 26, 2023Publication date: May 1, 2025Inventors: Jimmy Liu, Daniel Yu Hsu, Wilbur Y. Cheng, Wei Ying Shao

Uptake data were measured using three independent and complementary methodologies, and excellent agreement was observed among all three methodologies. Accordingly, this disclosure provides for methods of plasticizing poly(ethylene furanoate) film by cold water sorption, and provides a plasticized poly(ethylene furanoate) (PEF) film made according to the disclosed methods. Methods for making thin films of PEF are also provided.Type: GrantFiled: September 15, 2015Date of Patent: April 28, 2020Assignee: The Coca-Cola CompanyInventors: Ronald D.

Patent number: 7623468Abstract: The present invention provides a packet processing device and method. A parsing processor provides instruction-driven content inspection of network packets at 10-Gbps and above with a parsing engine that executes parsing instructions. A flow state unit maintains statefulness of packet flows to allow content inspection across several related network packets. A state-graph unit traces state-graph nodes to keyword indications and/or parsing instructions. The parsing instructions can be derived from a high-level application to emulate user-friendly parsing logic. The parsing processor sends parsed packets to a network processor unit for further processing.Type: GrantFiled: August 25, 2004Date of Patent: November 24, 2009Assignee: Cisco Technology, Inc.Inventors: Rina Panigrahy, Jackie Liu, Daniel Yu-Kwong Ng, Sanjay Jain, Nagaraj A.

Patent number: 7409526Abstract: A method and apparatus wherein only a partial key is stored in a hashing table is disclosed. By storing a partial key as opposed to storing the entire original key, less data is required to be stored in the hash table. This reduces the attendant memory costs. The reduction in memory requirement does not degrade the hash functionalities whatsoever. Hashing conflicts can be fully resolved by consulting the partial key.Type: GrantFiled: October 28, 2003Date of Patent: August 5, 2008Assignee: Cisco Technology, Inc.Inventors: Daniel Yu-Kwong Ng, Yung-Chin Chen

Patent number: 7359968Abstract: A method for sampling n-out-of-N packets in a network. Initially, the packet index corresponding to the N packets is pseudo-randomly shuffled. The shuffle function rearranges a set of numbers pseudo-randomly with a one-to-one mapping and no overlap. One way to perform the pseudo-random shuffle function is to use a linear feedback shift register (LFSR). The LFSR supports N being a power of two. However, the LFSR approach can be adapted to support N being any positive integer value. Based on the results of the shuffle function, sampling points are pseudo-randomly selected. By pseudo-randomly selecting the sample points, n-out-of-N sampling greatly minimizes biases.Type: GrantFiled: January 23, 2004Date of Patent: April 15, 2008Assignee: Cisco Technology, Inc.Inventors: Daniel Yu-Kwong Ng, Simon Wai-Ming Hsu
