Processor Power Down via Wireless LAN Recovery Signal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmitting systems cannot enter a power down mode without increasing hardware costs, as they require continuous polling to detect data transmission, leading to excessive power consumption.
Innovation Solution
A data transmitting system with a processor, two different transmitting interfaces, and a signal line between them, allowing the processor to enter a power down mode and generate a data transmission indication signal when data is available, triggering a recovery signal to revert to normal mode, thus eliminating the need for continuous polling and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the processor continuously polls the Bluetooth apparatus to detect data transmission, then data transmission reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements a feedback mechanism where the Bluetooth apparatus sends a data transmitting indication signal to the wireless LAN apparatus when data is ready, which then generates a recovery signal to wake the processor. This feedback loop eliminates the need for continuous polling while ensuring reliable data transmission notification.
Solution Approach 2:
The system allows the Bluetooth apparatus to autonomously generate indication signals when data is ready, and the wireless LAN apparatus automatically generates recovery signals without processor intervention. This self-service mechanism reduces processor workload and power consumption while maintaining transmission reliability.
2Use of energy by moving object
If additional hardware is added to notify the processor of data transmission, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent reuses existing hardware components (the signal transmitting line already connected for data transmission, and the wireless LAN apparatus's existing interface) to achieve the power saving function. The indication signal and recovery signal utilize existing signal paths and processing capabilities, eliminating the need for additional dedicated hardware.
Solution Approach 2:
The wireless LAN apparatus serves as an intermediary between the Bluetooth apparatus and the processor. It receives indication signals from the Bluetooth apparatus and generates corresponding recovery signals to wake the processor, eliminating the need for direct additional hardware connections to the processor.

AI summary
A data transmitting system, comprising: a processor; a first transmitting interface; a first transmitting apparatus; a second transmitting interface; a second transmitting apparatus and a signal transmitting line. The processor enters a power down mode when the first transmitting apparatus does not output data. The first transmitting generates a data transmitting indication signal when the processor is operated in the power down mode and the first transmitting apparatus has data to be output. The second transmitting apparatus generates a recovery signal according to the data transmitting indication signal, and transmits the recovery signal to the processor via the second transmitting interface. Thereby the processor goes back to a normal mode to control the first transmitting apparatus to output data.
