Firmware-Orchestrated Device Lighting Without Host OS Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition from x86 to ARM-based processors in Information Handling Systems (IHSs) presents challenges in managing device lighting, as existing solutions require host Operating System involvement for lighting control, leading to inefficiencies and limitations in customization and optimization.
Innovation Solution
A heterogeneous computing platform with a memory containing firmware instructions that enable devices to operate independently of the host OS, using an orchestrator to receive user presence or engagement information and modify lighting settings of IHS components, such as displays and keyboards, based on policies from ITDMs or OEMs, without OS involvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If host Operating System involvement is used for lighting control, then system compatibility and management are simplified, but customization capability and system optimization are reduced
Solution Approach 1:
The patent segments the lighting control function from the host OS by introducing a dedicated lighting control module that operates independently. This module receives sensor data directly and controls lighting components without requiring host OS intervention, thereby enabling customization while maintaining operational simplicity through modular design.
Solution Approach 2:
The patent introduces an intermediary lighting control module between the sensors and lighting components. This intermediary layer processes sensor data and generates control signals independently, allowing the system to achieve both ease of operation through centralized control and adaptability through customizable control logic within the intermediary module.
2Reliability
If host Operating System involvement is used for lighting control, then system integration is maintained, but response speed and efficiency are reduced
Solution Approach 1:
The patent segments the lighting control function from the host OS into an independent module with direct access to sensors and lighting components. This segmentation creates a dedicated control pathway that bypasses the host OS, significantly reducing response time while maintaining system integration through defined communication interfaces.
Solution Approach 2:
The lighting control module performs preliminary processing of sensor data and generates control signals independently before any host OS involvement is needed. This preliminary action enables rapid response to lighting conditions while maintaining system integration through subsequent coordination with the host OS when required.
3Adaptability or versatility
If firmware-based device control is implemented, then customization and optimization are improved, but device complexity increases
Solution Approach 1:
The patent implements a universal firmware-based control module that handles multiple functions including sensor data processing, lighting control, and communication with both host OS and standalone operation. This multi-functional approach enables extensive customization while managing device complexity by consolidating control logic into a single versatile module rather than multiple specialized components.
