Patent number: 12000407Abstract: A ceiling fan blade assembly structure includes a blade holder, multiple fan blades, and multiple locking assemblies. Multiple fan blade assembly portions are disposed at an outer side of the blade holder. Each fan blade assembly portion includes two first side plates parallel to each other, a first radial positioning portion, and two first vertical positioning portions disposed on the two first side plates. Each fan blade has a fan blade connection portion that includes two second side plates, a second radial positioning portion, and two second vertical positioning portions. The second and the first radial positioning portions are engaged with each other, and the two second and first vertical positioning portions are engaged with each other. Accordingly, the fan blade connection portion is preliminarily positioned on the fan blade assembly portion. Through the locking assembly, the first and the second radial positioning portions are locked together.Type: GrantFiled: July 13, 2023Date of Patent: June 4, 2024Assignee: HOTECK INC.Inventors: Lung-Fa Hsieh, Yu-Chen Hsieh, Min-Yuan Hsiao, Wen-Ting Tang, Hsin-Chu Chang, Ying-Pin Chiang

Patent number: 7940334Abstract: The invention discloses a Gamma transform unit. The Gamma transform unit has a lookup table. The lookup table stores a plurality of difference values corresponding to a plurality of predetermined input values. Each of the difference values substantially equals a difference between an ideal output value and a Gamma function output value, both of which correspond to one of the predetermined input values. After the Gamma transform unit has received an input value, it generates a required Gamma function output value corresponding to the received input value through referring to the lookup table.Type: GrantFiled: December 13, 2006Date of Patent: May 10, 2011Assignee: Princeton Technology CorporationInventors: Ying-Yuan Tang, Hwa-Hsiang Chang, Hui-Fen Chia

Patent number: 7835595Abstract: An image processing method for scaling an image from an original resolution to a target resolution is provided. A pixel value PT of a target pixel point NT in the target resolution is theoretically composed of original pixel values P1-PK of original pixel points N1-NK in the original resolution, wherein K is a positive integer larger than 1. First, theoretical combination ratios R1-RK corresponding to the original pixel points N1-NK are found. Then, the theoretical combination ratios R1-RK are converted to corresponding weights W1-WK, wherein each of the corresponding weights W1-WK is an integer between 1 and 2n, n is an integer, and the sum of the corresponding weights W1-WK is 2n. The original pixel values P1-PK are calculated with the corresponding weights W1-WK using a scaler, to generate the pixel value PT of the target pixel point NT and complete the image processing.Type: GrantFiled: January 12, 2007Date of Patent: November 16, 2010Assignee: Princton Technology CorporationInventors: Hui-Fen Chia, Ying-Yuan Tang

Patent number: 7392447Abstract: The invention provides a method and circuitry to save power in a synchronous logic ASIC with low overhead. The scan chain(s) and boundary scan mechanism of the synchronous logic ASIC are used and modified for shifting out current states of internal memory devices of the synchronous logic ASIC to an external memory and for retaining the power-off blocks' primary output values to the memory devices of the boundary scan circuit, so the proposed gated power method is efficient and low overhead in the synchronous, flop-based, logic circuit design.Type: GrantFiled: October 25, 2004Date of Patent: June 24, 2008Assignee: Princeton Technology CorporationInventors: Ying Yuan Tang, Yung Sen Chen, De Yu Kao

Publication number: 20060104352Abstract: The invention provides a method to reduce the computation complexity by performing the motion estimation in the frequency domain with tiny hardware overhead and a little modification of the video compression algorithms. Since human eyes are not so sensitive in the high frequency range as in the low frequency range, the present invention only takes low frequency information for finding the motion vector in motion estimation.Type: ApplicationFiled: November 17, 2004Publication date: May 18, 2006Applicant: Princeton Technology CorporationInventors: Yung-Sen Chen, De-Yu Kao, Ying-Yuan Tang
