Transceiver Resynchronization Using Synthetic Sensor Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transmitters entering sleep mode cause synchronization loss with receivers, leading to data latency, corruption, and loss during resynchronization, affecting the completeness and timeliness of sensor data used by devices.
Innovation Solution
Generating artificial or synthetic data using a coprocessor to synchronize devices before actual data transmission, ensuring timely and accurate data delivery to host processors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the transmitter enters sleep mode to conserve energy, then energy consumption is reduced, but synchronization is lost between transmitter and receiver
Solution Approach 1:
The system performs preliminary synchronization actions by transmitting synthetic data packets before actual sensor data transmission. This preliminary action maintains the communication link active and synchronized, allowing the transmitter to enter sleep mode without losing synchronization state, thus resolving the contradiction between energy conservation and synchronization reliability
Solution Approach 2:
Synthetic data packets serve as an intermediary mechanism between the transmitter and receiver. These packets maintain the communication link and synchronization without requiring actual sensor data, enabling the transmitter to conserve energy while preserving synchronization through the intermediary synthetic data transmissions
2Reliability
If the transmitter re-synchronizes the link with the receiver upon activation, then synchronization is restored, but additional latency is introduced
Solution Approach 1:
The system performs synchronization preliminarily by transmitting synthetic data packets that carry synchronization information before actual data transmission. This preliminary synchronization action eliminates the need for time-consuming re-synchronization upon activation, thus reducing latency while maintaining synchronization reliability
Solution Approach 2:
The system skips the traditional time-consuming re-synchronization process by using synthetic data packets that inherently carry synchronization information. This allows the transmitter to rapidly re-establish synchronization without going through the full re-synchronization sequence, thus reducing the time loss
3Loss of time
If the transmitter transmits sensor data immediately upon activation, then data timeliness is improved, but data loss or corruption occurs due to lack of synchronization
Solution Approach 1:
The system performs preliminary synchronization by transmitting synthetic data packets before actual sensor data. This preliminary action ensures the communication link is synchronized and ready to receive actual data immediately, allowing timely transmission without data loss or corruption
Solution Approach 2:
The synthetic data packets provide a cushioning mechanism that prepares the communication link in advance. This beforehand cushioning ensures that when actual sensor data arrives, the receiver is already synchronized and ready to receive it completely and accurately, preventing data loss while maintaining timeliness

AI summary
Systems and methods are disclosed for generating additional data for one or more frames based, at least in part, on re-synchronization of a transceiver that provides the additional data to one or more additional processors. Systems identity an indication of a trigger that is associated with the one or more frames, cause a set of sensors to generate one or more frames in response to the trigger, generate the additional data, and transmit the additional data to the transceiver in advance of providing the one or more frames.
