Christopher Chow has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10179378
    Abstract: The present invention includes methods for treating laser-processed materials having an odor generated during the laser processing. The present method includes treating the laser-processed materials with heat to dissipate the odor from the material. The laser processed material may be secured to avoid curling during the heating process. The method can also include a cooling step after heating of the laser-processed material. Multiple cycles of heating and cooling may also be performed to substantially reduce or eliminate the odor from the laser-processed material. The invention also includes articles made according to the method and apparatus for producing laser processed materials having substantially reduced odor.

  • Publication number: 20160001496
    Abstract: An electrically conductive touch sensor panel construction and method and laser system for fabricating the same. The transparent touch sensor panel comprises at least two conductive coatings to provide a drive layer and a sense layer. The drive and sense layers are laminated together or otherwise assembled in a touch panel construction and in selected alignment. The layers are then subsequently laser patterned to form the conductive pathways for the touch panel sensor. The drive and sense layers may be concurrently or sequentially laser processed to form a selected pattern in each layer such that the drive and sense layers are substantially aligned forming a far more precise pattern array for the panel.

  • Patent number: 9174308
    Abstract: A method of scoring a multi-layer film structure, wherein the multi-layer film structure comprises a metal layer and polymer layer bonded to each other, the method comprises using a single laser beam incident to the polymer layer to produce a score line in the polymer layer, wherein the laser energy is absorbed only by the metal layer.

  • Patent number: 8705676
    Abstract: A multi-tone transceiver including: a transform component, a tone selector, an error detector, an aggregator and an oscillator. The transform component transforms received communications from the time domain to the frequency domain. The tone selector selects a sub-set of the received tones which exhibit an elevated signal-to-noise ratio (SNR) as a clock recovery tone set (CRTS) and drops and add tones to the CRTS as required by changes in the SNR of the individual tones. The error detector detects phase errors in each received tone of the CRTS. The aggregator calculates an average aggregate phase error from all tones in the CRTS. The oscillator controls clocking of the transceiver. The oscillator is responsive to the average aggregate phase error to adjust a clock phase in a direction which reduces a phase error with a clock on the opposing transceiver.

  • Publication number: 20130299491
    Abstract: The present invention includes methods for treating a laser-processed material that produces an odor due to the laser processing. The present method includes treating the laser-processed material with heat to dissipate the odor from the material. The method can also include a cooling step after heating of the laser-processed material. Multiple cycles of heating and cooling may also be performed to substantially reduce or eliminate the odor from the laser processed material. The invention also includes an article made according to the method and apparatus for laser processing with the produced article having substantially reduced odor.
