Pulsed Data Transmission with Non-Volatile Memory Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission systems for electronic circuits fail to efficiently manage power supply continuity and data transmission, particularly in low-energy consumption devices like e-paper, where continuous functioning is not essential.
Innovation Solution
A method and system that transmit data pulses over an electrical connection line, allowing each pulse to both supply and transmit data, with the option to cut power between pulses, store data in non-volatile memory, and use specific pulse durations for bit transmission, initialization, and control, ensuring the second circuit can interpret and execute commands without continuous power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous power supply is maintained to ensure continuous functioning of the second circuit, then reliability is improved, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by transmitting data in discrete pulses rather than continuous signals. The second circuit operates intermittently - active during data pulse reception and storage, then enters low-power or off-state. This periodic operation pattern allows the circuit to maintain reliability for data capture while dramatically reducing average energy consumption compared to continuous operation.
Solution Approach 2:
The patent extracts the essential function of data acquisition from continuous operation. By using non-volatile memory, the system separates data storage from continuous power dependency - data is captured and stored during brief active periods, then preserved without power. This extraction allows the circuit to be turned off between operations, resolving the contradiction between continuous functioning and energy savings.
2Loss of energy
If power is cut between data pulses to reduce energy consumption, then energy efficiency is improved, but data transmission continuity is disrupted
Solution Approach 1:
The patent introduces non-volatile memory as an intermediary between the pulsed data input and the final data output. During active pulses, data is received and stored in this intermediary storage. When power is cut between pulses, the intermediary memory preserves the data without power. This mediator resolves the contradiction by decoupling data reception from continuous power supply.
Solution Approach 2:
The system performs preliminary action by storing data in non-volatile memory during brief active periods before power is cut. This advance storage ensures data is secured and preserved before the power interruption occurs, maintaining data integrity and transmission continuity despite the intermittent power supply pattern.
3Use of energy by moving object
If data is stored in non-volatile memory during each pulse to enable power cutting, then energy consumption is reduced, but device complexity increases
Solution Approach 1:
The electrical connection line serves multiple functions: it acts as both the data transmission medium and the power supply conduit. During active pulses, the same line delivers both energy and data signals to the second circuit. This multi-functionality reduces the need for separate dedicated power and data lines, thereby limiting the increase in device complexity while enabling the energy-saving pulsed operation with non-volatile memory storage.

AI summary
The invention relates to the field of transmitting series of data between electronic circuits, and more specifically a method and a system for transmitting series of data, from a first electronic circuit to at least one second electronic circuit, via an electrical connection line between the first circuit and the second circuit, in reference to a ground line common to the circuits, of at least one series of data pulses. Each data pulse makes it possible to both electrically supply the second circuit and to transmit an item of data which can be interpreted by the second circuit. The supplying of the second circuit by the first circuit is cut between two successive pulses. For each data pulse and before the second circuit is switched off, because of failure in supply, the item of data transmitted by the pulse is stored on a non-volatile memory support of the second circuit.
