US Patent:

6625629, Sep 23, 2003

Filed:

May 23, 2000

Appl. No.:

09/577171

Inventors:

Guillermo Garcia - San Mateo CA

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 1710

US Classification:

708315, 708321

Abstract:

A system ( ) for signal processing using one or more filters includes a controller ( ) that partitions an impulse response of a filter into a plurality of impulse response blocks and calculates a Discrete Fourier Transform (DFT) of each impulse response block using a Fast Fourier Transform (FFT) algorithm. A processor ( ) that is coupled to the controller ( ) receives an input sample block including samples of a signal to be processed and receives the DFT of each impulse response block from the controller ( ). The processor ( ) calculates a DFT of the input sample block using an FFT algorithm, performs a spectral multiplication of the DFT of the input sample block with the DFT of each impulse response block, overlap-adds the blocks resulting from each spectral multiplication to create an output spectral block, performs an inverse FFT on the output spectral block to create an output sample block, and communicates the output sample block.

International Classification:

G02F 1/153
G02F 1/155
G02F 1/1523

Abstract:

An electrochromic (EC) device includes a first substrate, a second substrate, a transparent first conductor disposed between the first and second substrates, a transparent second conductor disposed between the first and second substrates, a working electrode disposed between the first and second conductors, a counter electrode disposed between the working electrode and the second conductor, and an electrolyte disposed between the working and counter electrodes. At least one of the first or second conductors is a multipart conductor which includes a transparent first conductive film, a first contact strip extending lengthwise in a first direction which is perpendicular to a second direction, along a first side of the EC device, and first conductive lines extending from the first contact strip toward an opposing second side of the EC device. The multipart conductor has a lower effective sheet resistance in the second direction than in the first direction.

Abstract:

An electrochromic device includes an optically transparent first substrate, a first transparent conductor disposed on the first substrate, a counter electrode disposed on the first transparent conductor, an optically transparent, ionically conductive first capping layer disposed on the counter electrode, and configured to permit diffusion of alkali metal ions, and to block the diffusion of organic compounds and carbon, an optically transparent second substrate, a second transparent conductor disposed on the second substrate, a working electrode comprising electrochromic nanoparticles disposed on the second transparent conductor, and an electrolyte disposed between the first capping layer and the working electrode.
