Dual-Processor Battery Management for Portable Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals, such as cellular phones and tablets, face limited battery life due to ongoing power consumption from background applications and continuous scanning for signals or communications, even when not actively used.
Innovation Solution
Implementing a dual-processor system with a first processor for active operation mode and a second processor for reduced-power sleep mode, where the second processor monitors for specific events to transition between modes, thereby minimizing battery consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the portable terminal operates continuously in operation mode to ensure immediate responsiveness, then the responsiveness and availability are improved, but the battery power consumption increases
Solution Approach 1:
The system dynamically transitions between operation mode and sleep mode based on detected events. The processor adjusts its operational state in real-time, switching from full operation to low-power mode when no events are detected, and back to operation mode when events occur, thereby optimizing the balance between responsiveness and power consumption
Solution Approach 2:
The system employs periodic event detection during sleep mode, where the processor checks for events at intervals rather than continuously monitoring. This periodic checking mechanism allows the system to maintain sleep mode for extended periods while still being able to detect and respond to events, reducing overall power consumption while preserving responsiveness
2Reliability
If background applications and signal scanning are continuously running to ensure immediate availability, then the service availability is improved, but the battery life decreases
Solution Approach 1:
The patent extracts and separates the event detection function from the main processor operations. During sleep mode, non-essential background applications and signal scanning are suspended or minimized, while the system maintains the ability to detect specific events that require attention, thereby reducing power consumption while preserving critical service availability
Solution Approach 2:
The system automatically manages its own power states by detecting events and transitioning between modes without requiring continuous user intervention or manual configuration. The processor autonomously determines when to enter sleep mode and when to resume operation, optimizing battery life while maintaining service availability through event-driven wake-up

AI summary
Aspects include a method, system, and computer program product for managing battery life in a portable terminal. Managing battery life in the portable terminal may include enabling a sleep mode in the portable terminal in response to detection of a sleep event, and enabling an operation mode in the portable terminal in response to detection of an operation event. The portable terminal may include a first processor and a second processor. The enabling the sleep mode may include reducing power consumption of the first processor. The enabling the operation mode may include detecting the operation event with the second processor while the portable terminal is in the sleep mode. A rate of battery power consumption during the sleep mode may be lower than a rate of battery power consumption during the operation mode.
