Patent number: 11745662Abstract: An electrochromic mirror module including a light-transmissive substrate, an opaque touch sensing layer and an electrochromic device is provided. The light-transmissive substrate has a visible surface and a back surface disposed opposite to the visible surface. The opaque touch sensing layer and the electrochromic layer are disposed on the back surface. Distribution areas of the opaque touch sensing layer and the electrochromic layer are different on the back surface. An electrochromic mirror module including reflective layer and electrochromic device is also provided.Type: GrantFiled: August 20, 2020Date of Patent: September 5, 2023Assignee: Unimicron Technology Corp.Inventors: An-Sheng Lee, Meng-Chia Chan, Ming-Yuan Hsu, Po-Ching Chan, Shih-Yao Lin, Cheng-Ming Weng

Patent number: 8852746Abstract: A substrate coating and a method of forming the same are provided. The substrate coating includes a first layer formed on a substrate, in which the composition of the first layer includes at least silicon-rich-carbon, and the amount of silicon is about equal to or greater than the amount of carbon; and a second layer formed on the first layer, in which the composition of the second layer includes at least fluorine doped diamond-like-carbon. The substrate coating not only is easy to clean, has good wearing performance, and provides a smooth surface, but also has better adhesion to prevent peeling off.Type: GrantFiled: March 11, 2011Date of Patent: October 7, 2014Assignee: Winsky Technology LimitedInventors: Kit Ling Ng, Xin Chao Duan, Po Ching Chan, Winston Chan

Patent number: 8417752Abstract: An equalizer circuitry that includes an equalizer stage having a programmable current source is described. In one implementation, the programmable current source cancels voltage offset. Also, in one implementation, the programmable current source is programmable in user mode. Furthermore, in one implementation, the equalizer circuitry includes a plurality of equalizer stages including the equalizer stage having a programmable current source, where the equalizer stage having a programmable current source is a second equalizer stage in the plurality of equalizer stages. Also, in one implementation, the programmable current source includes a plurality of current sources coupled in parallel and a plurality of sets of control switches for controlling the plurality of current sources.Type: GrantFiled: May 21, 2009Date of Patent: April 9, 2013Assignee: Altera CorporationInventors: Doris Po Ching Chan, Simardeep Maangat, Thungoc M. Tran, Sergey Shumarayev

Patent number: 8391350Abstract: Decision feedback equalizer (“DFE”) circuitry bases determination of the coefficients that are used in its various taps on the algebraic sign of the current value of an error signal and prior serial data signal values output by the DFE circuitry. Use of such algebraic sign information (rather than full error signal values) greatly simplifies the circuitry needed to determine the tap coefficients. The DFE circuitry can be adaptive, i.e., such that it automatically adjusts the tap coefficients for changing serial data signal transmission conditions.Type: GrantFiled: September 3, 2010Date of Patent: March 5, 2013Assignee: Altera CorporationInventors: Doris Po Ching Chan, Thungoc M.

Patent number: 8208523Abstract: Equalization of an incoming data signal can be controlled by sampling that signal at times when data values in that signal should be stable (“data samples”) and when that signal should be in transition between successive data values that are different (“transition samples”). A transition sample that has been taken between two successive differently valued data samples is compared to a reference value (which can be one of those two data samples). The result of this comparison can be used as part of a determination as to whether to increase or decrease equalization of the incoming data signal.Type: GrantFiled: April 4, 2011Date of Patent: June 26, 2012Assignee: Altera CorporationInventors: Wilson Wong, Doris Po Ching Chan, Sergey Shumarayev, Simardeep Maangat, Tim Tri Hoang, Tin H.
