Fundamental features

Fundamental Features

  • An ability to sample analog voltage signal range from -12 V to 12 V via BNC;

  • An ability to reconstruct and display the sampled signal on VGA display;

  • An ability to create user interface and realize basic signal measurements, such as frequency and peak-to-peak voltage;

  • An ability to store/load the sampled signal to/from external memory;

  • An ability to replay a stored signal.


Parallel patented products

Parallel Patented Products

  • Self Adjusting Oscilloscope

    Patent Number: US 4743844

  • Method And System For Secure Digital Triggering For An Oscilloscope

    Patent Number: US 7860674 B2

  • Oscilloscope System For Acquiring, Processing, And Displaying Information

    Patent Number: US 4225940


Self adjusting oscilloscope

Self Adjusting Oscilloscope

  • Substantial Similarities:

    • Same structure in sampling

    • Similar user interfaces

    • Store waveform to memory

    • Display Controller/ Driver

    • Utilize Microcomputer,

      RAM and ROM

  • Distinct Differences:

    • Analog to Digital conversion through ADC channel on the MCU

    • Display via VGA output and controlled by FPGA

    • Playback the stored waveforms


Digital triggering

Digital Triggering

  • Substantial Similarities:

    • Similar trigger methodology with slope detector

    • Same sampling and comparison process

  • Distinct Differences:

    • 3-points detection algorithm (in MCU)

    • Dynamic trigger setting available


Signal processing

Signal Processing

  • Substantial Similarities:

    • Input sampling with A/D converter

    • Sampled data will be stored in to memory waiting for processing

    • Reconstruct signal for display

  • Distinct Differences:

    • Use TIMER delay to plot x-axis

    • Digital reconstruction via FPGA, no D/A converter needed


Is it infringement

Is it Infringement?

  • Yes because…

    • The product is already in the market and some functions are literally the same.

    • Same tasks are performed in substantially the same way (i.e. A/D conversion, user interface…)

  • No because…

    • Different way to achieve some tasks (i.e. Input attenuation, display control and triggering algorithm).
