  • Patent number: 11745662
    Abstract: 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.

  • Patent number: 8852746
    Abstract: 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.

  • Patent number: 8417752
    Abstract: 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.

  • Patent number: 8391350
    Abstract: 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.

  • Patent number: 8208523
    Abstract: 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.
