Patent number: 10090755Abstract: A method includes comparing, by a voltage-second (VS) controller, a first duty cycle used to control a first switch at a primary side of a power transformer of a DC-to-DC converter with a threshold. The method further includes if a value of the first duty cycle is less than the threshold, controlling, by the VS controller, a second duty cycle used to control a second switch at a secondary side of the power transformer, and maintaining a voltage level at an output voltage node at a non-zero value, and if the value of the first duty cycle is greater than the threshold, controlling, by an output voltage loop, the second duty cycle based on the first duty cycle, and monotonically increasing the voltage level the at the output voltage node from the non-zero value to a predetermined value.Type: GrantFiled: January 17, 2017Date of Patent: October 2, 2018Assignee: Texas Instruments IncorporatedInventors: Frank Tang, Kening Gao, Lin Sheng, Danyang Zhu

Publication number: 20130067307Abstract: A computer-implemented technique includes receiving a request for a translation webpage and generating a user interface webpage for the translation webpage. The user interface webpage includes a text input portion, a translated text output portion, a source language selection portion, and a target language selection portion. The source language selection portion includes a quick source language selection icon identifying a potential source language, and a source language selection list including a plurality of potential source languages. The target language selection portion includes a quick target language selection icon identifying a potential target language, and a target language selection list including a plurality of potential target languages.Type: ApplicationFiled: November 29, 2011Publication date: March 14, 2013Applicant: GOOGLE INC.Inventors: Chao Tian, Awaneesh Verma, Joshua James Estelle, Yung-Fong Frank Tang

Publication number: 20040097689Abstract: The present invention relates to a photosensitive thermosetting resin, which has more than two of ethylenically double bonds and carboxyl functional groups in one molecule thereof. The invention also relates to a solder resist ink composition, including (A) the above photosensitive thermosetting resin, (B) a photo-polymerization initiator, and (C) a thermo-hardener. The solder resist ink composition is suitably applied to a printed circuit board, and has excellent photosensitivity, solder resistance, electrical corrosion resistance, insulating properties and adhesion to copper foil.Type: ApplicationFiled: November 18, 2002Publication date: May 20, 2004Applicant: Great Eastern Resins Industrial Co., Ltd., Taiwan, R.O.C.Inventor: Frank Tang

Patent number: 5793381Abstract: A character code conversion system that provides round trip fidelity, while ensuring that the resulting character codes are interchangeable with other platforms. The code conversion system is able to map a single source character or a sequence of characters to either a single target character or a sequence of target characters. With round trip fidelity, source text can be converted to target text and then back again to the original source text. The interchangability is ensured by maximizing the use of standard target characters, and by minimizing the use of private characters. The code conversion is particularly useful for converting to/from Unicode characters from/to other character sets.Type: GrantFiled: September 13, 1995Date of Patent: August 11, 1998Assignee: Apple Computer, Inc.Inventors: Peter K. Edberg, John I. McConnell, Yung-Fong Frank Tang, Andrew M. Daniels

Patent number: 5784071Abstract: A code conversion system that takes context into consideration when converting characters from a source character encoding to a target character encoding. The code conversion system is able to map a single source character or a sequence of characters to either a single target character or a sequence of target characters. By determining the context of the characters, the code conversion system can then utilize the determined context of the characters to ensure that the correct mapping to the target encoding is obtained.Type: GrantFiled: September 13, 1995Date of Patent: July 21, 1998Assignee: Apple Computer, Inc.Inventors: Yung-Fong Frank Tang, Andrew M. Daniels, Peter K. Edberg, John I. McConnell

Patent number: 5784069Abstract: A code conversion system that takes direction into consideration when converting characters from a source character encoding to a target character encoding is disclosed. The code conversion system is able to map a single source character or a sequence of characters to either a single target character or a sequence of target characters. By determining or resolving the direction of the characters being converted, the code conversion system can then utilize the determined or resolved direction of the characters to ensure that the correct mapping to the target character encoding is obtained.Type: GrantFiled: September 13, 1995Date of Patent: July 21, 1998Assignee: Apple Computer, Inc.Inventors: Andrew M. Daniels, Yung-Fong Frank Tang, Peter K. Edberg, John I. McConnell
