Variable Pressure Displacement Sensor Event Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in accurately processing and suppressing computing input events from variable pressure and displacement sensors, particularly in distinguishing between different pressure or displacement zones and managing timing delays for event generation.
Innovation Solution
The implementation of a variable pressure or displacement (VPD) sensor system with VPD circuitry that processes real-time sensor data to determine the current pressure or displacement zone and selectively generates computing input events only after a defined time delay, allowing for suppression of events during specific sensor states, such as initial activation or release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If variable pressure or displacement sensors are used to detect multiple pressure zones, then the versatility of input detection is improved, but the complexity of processing and suppressing input events increases
Solution Approach 1:
The system pre-defines multiple pressure zones with specific threshold values before operation. When a sensor input is received, the system checks against these pre-established zone definitions to determine which zone the input falls into, eliminating the need for complex real-time calculations and simplifying the event processing logic
Solution Approach 2:
The pressure range is segmented into multiple discrete zones (e.g., first pressure zone, second pressure zone, third pressure zone) with defined boundaries. Each zone can be independently configured and processed, allowing the system to handle different pressure levels as separate, manageable events rather than a continuous complex range
2Measurement precision
If time delay is implemented to suppress unwanted input events, then the accuracy of event processing is improved, but the response time of the system increases
Solution Approach 1:
The time delay parameter is made dynamic and configurable rather than fixed. The system allows adjustment of the delay duration based on different operational contexts and user preferences, enabling optimization between accuracy and response time for different scenarios
Solution Approach 2:
A time delay mechanism acts as an intermediary between sensor input and event processing. This intermediary component filters out spurious or premature events by holding the input state for a configurable duration before triggering the actual processing, improving accuracy without permanently slowing the system
3Adaptability or versatility
If multiple pressure zones are defined with different input events, then the functionality of the sensor system is improved, but the difficulty of managing and suppressing events increases
Solution Approach 1:
The system implements a universal event management framework that handles all pressure zones through a common interface and configuration structure. Despite supporting multiple zones with different events, the management mechanism remains consistent and standardized, making it easier to control and suppress events across all zones through unified commands

AI summary
Systems and methods are disclosed herein that may be implemented to selectably suppress computing input events that are generated for an information handling system based on output signals received from a variable pressure or displacement (VPD) sensor that correspond to one or more pressure or displacement zones defined for the VPD sensor. Using the disclosed systems and methods, computing input events based on sensor output signals from one or more given VPD sensing zones may be selectably suppressed and/or withheld during sensor pressure or displacement changes from further host system processing according to a time delay, e.g., as a function of the elapsed time taken for a user to depress or release a given VPD sensor.
