Electrochromic devices
ActiveUS20110267674A1Highly conductiveHigh resistanceDoors/windowsVacuum evaporation coatingIonElectricity
Conventional electrochromic devices frequently suffer from poor reliability and poor performance. Improvements are made using entirely solid and inorganic materials. Electrochromic devices are fabricated by forming an ion conducting electronically insulating interfacial region that serves as an IC layer. In some methods, the interfacial region is formed after formation of an electrochromic and a counter electrode layer. The interfacial region contains an ion conducting electronically insulating material along with components of the electrochromic and / or the counter electrode layer. Materials and microstructure of the electrochromic devices provide improvements in performance and reliability over conventional devices.

Disclosed is a method and system for digital watermarking of multimedia signals. The input multimedia signal is represented using an inverse difference pyramid decomposition. Spectrum coefficients may be calculated for each level of the pyramid using a new kind of complex Hadamard transform, the matrix of which is distinguished from the known ones by the fact that only one-fourth of its coefficients are complex numbers. The phases of a previously selected part of the low-frequency coefficients are modified with the watermark data, limiting the angles of the phase changes in a gap of several degrees only. After an inverse complex Hadamard Transform, the values of the coefficients from all pyramid levels are summed up and the result is the watermarked signal. The watermark can contain multiple independent levels for each level of the pyramid.

NAND string wordline delay reduction
ActiveUS7064981B2Extension of timeEnhancing Capacitive CouplingRead-only memoriesDigital storageCapacitanceLow voltage
An improved NAND Flash memory and word line selection method has been described, that takes advantage of the asymmetric nature of the word line to word line capacitive coupling to reduce word line selection delay by driving the adjacent word lines to a higher initial voltage and then reducing it to the final target voltage. As the capacitive coupling in between the NAND word lines is a larger effect when the voltages are being lowered, this has the effect of damping out the voltage initially induced in the lower voltage word line by the rising voltages on the adjacent word lines, reducing the overall selection time.

Simple matrix addressing in a display
InactiveUS20060238443A1High resistanceEnsure persistenceBioreactor/fermenter combinationsBiological substance pretreatmentsCapacitanceHysteresis
An addressing mechanism for charging and discharging quasi-capacitive elements in an X-Y matrix. The addressing mechanism may be configured to toggle a resistor-capacitor (RC) time constant between large and small values such as by opening or closing a circuit path to a low impedance resistor disposed in parallel with a higher impedance in-line resistor. When this occurs, elements in the X-Y matrix can be addressed and controlled. The X-Y matrix may be comprised of multiple “rows” and “columns” of conductors where crosstalk may occur along the columns and rows. Crosstalk may be curtailed by using either hysteresis management or global control of the row's impedance along its entire length. The resulting control obviates the need for active devices at each matrix element to perform the switching functions.
