US Patent:

8264678, Sep 11, 2012
Filed:

Dec 26, 2008
Appl. No.:

12/811252
Inventors:

Vitali Souchkov - Walnut Creek CA, US
Rob Van Dalen - Bergeijk, NL
Assignee:

NXP B.V. - Eindhoven
International Classification:

G01B 11/26
G01J 1/42
US Classification:

3561412, 356218
Abstract:

A light sensor and light sensing system to detect an intensity of incident light and an angle of incidence of the incident light. The light sensor includes a dielectric layer, a plurality of photo detectors coupled relative to the dielectric layer, and a plurality of stacks of opaque slats embedded within the dielectric layer. The dielectric layer is substantially transparent to the incident light. The photo detectors detect the incident light through the dielectric layer. The stacks of opaque slats are approximately parallel to an interface between the dielectric layer and the photo detectors. The stacks of opaque slats define light apertures between adjacent stacks of opaque slats. At least some of the stacks of opaque slats are arranged at a non-zero angle relative to other stacks of the opaque slats.

US Patent:

8274491, Sep 25, 2012
Filed:

Dec 1, 2010
Appl. No.:

12/957489
Inventors:

Vitali Souchkov - Walnut Creek CA, US
Assignee:

PixArt Imaging Inc. - Science-Based Industrial Park, Hsin-Chu
International Classification:

G06F 3/041
US Classification:

345173
Abstract:

Various embodiments of readout circuits are disclosed where no touchscreen or touch panel recharge is required, and the amount of time available for signal acquisition is twice that relative to prior art touchscreen or touch panel readout circuits. Voltage offsets of the integrating amplifiers may be compensated for by notch filtering signals stored in readout circuit capacitors. Some embodiments of readout circuits disclosed herein permit large dynamic range capacitive touchscreen or touch panel signals to be processed, and do not require panel reset. Readout circuits are disclosed that permit doubling of the signal acquisition rate and pre-filtering of acquired touch panel signals for improved immunity from harmonic EMI. Signal acquisition and temporary storage may be carried out using the same capacitors in such readout circuits.

Jul 15, 2011
Appl. No.:

13/184132
Inventors:

Vitali Souchkov - Walnut Creek CA, US
Assignee:

Pixart Imaging, Inc. - Hsin-Chu
International Classification:

G06F 3/045
US Classification:

345174
Abstract:

Various embodiments of capacitive touchscreen driving and sensing circuits are disclosed, where during a first phase the mutual capacitance between a given drive electrode and a given sense electrode is charged up to a first charge value corresponding substantially to a drive voltage times the mutual capacitance. During a second phase the charge storage capacitor is charged up to a value corresponding approximately to a difference in touchscreen capacitance network charges occurring during the first and second phases. The first and second phases do not overlap in time. Dark frame signals may also be acquired from the touchscreen to calibrate differences in touchscreen capacitance network charges.

Filed:

Aug 11, 2011
Appl. No.:

13/208318
Inventors:

Vitali Souchkov - Walnut Creek CA, US
Assignee:

Pixart Imaging Inc. - Hsin-Chu
International Classification:

H03M 1/38
US Classification:

341161, 341155, 341156
Abstract:

Various embodiments of methods and devices for reducing capacitor mismatch errors in a pipeline analog-to-digital converter (ADC) are disclosed, where in a pipeline element circuit and during a first phase, an input voltage provided by a sample-and-hold circuit is presented to first and second capacitors arranged in parallel in the pipeline element circuit. During a second phase, a second voltage corresponding to a second charge associated with the second capacitance is amplified and stored in the pipeline element circuit. During a third phase, the same input voltage of the first phase is again presented to the first and second capacitors, which are arranged in parallel in the pipeline element circuit. During a fourth phase a first voltage corresponding to the first charge is amplified and stored in the pipeline element circuit. After the first, second, third and fourth phases have been completed, digital representations of the first and second voltages are sent though corresponding registers for subsequent averaging along with digital representations of first and second voltages provided by other pipeline element circuits to produce a digital capacitor mismatch error corrected output.
