Oscilloscope Waveform Selection Using Click-Region Energy Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital oscilloscopes face challenges in accurately selecting a target waveform from multiple overlapping channels due to the difficulty in distinguishing and correctly clicking on the intended waveform, often resulting in incorrect selections.
Innovation Solution
A method that determines a waveform selection region based on a click position, calculates waveform energies within this region, and selects the waveform with the highest energy proportion as the target, using modules to identify the user's click intention and improve accuracy.

1Quantity of substance
If multiple waveforms are displayed in an overlapping manner on a limited display size, then the display can show more channel waveforms simultaneously, but it becomes difficult to distinguish and correctly select the target waveform
Solution Approach 1:
The patent divides the display into multiple waveform selection regions, each associated with a specific channel. When a user clicks on the display, the system determines which waveform selection region the click falls into, thereby identifying the intended channel. This segmentation allows accurate waveform selection even when multiple waveforms are overlapped on a limited display.
2Ease of operation
If the user clicks on the display to select a waveform, then the selection operation can be performed, but the finger or mouse pointer may touch multiple waveforms simultaneously causing incorrect selection
Solution Approach 1:
The patent introduces waveform selection regions as intermediary elements between the user's click input and the waveform selection output. Each waveform selection region acts as a mediator that maps a click position to a specific channel, ensuring that even when the click position is imprecise or overlaps multiple waveforms, the correct waveform is selected based on which region the click falls into.
3Area of stationary object
If the display size is limited, then the device remains compact and portable, but there is insufficient space to separate and distinguish individual waveforms clearly
Solution Approach 1:
The patent transitions from spatial separation (two-dimensional display layout) to a different dimension of organization by introducing waveform selection regions that are defined by their association with channels rather than their visual separation on the display. This allows the system to maintain compact display size while enabling accurate waveform identification through the region-based selection mechanism.
