Engineering Contradiction Analysis
1Productivity
If a simple digital transmission protocol is used, then implementation complexity is reduced and robustness is improved, but data throughput is limited
Solution Approach 1:
The patent encodes additional data in the temporal dimension by utilizing the duration of signal transitions. While the original protocol uses transition edges for data encoding, this invention extracts additional information from the time interval between transitions, effectively adding a temporal dimension to the data transmission capacity without increasing signal frequency or complexity
Solution Approach 2:
The patent modifies the interpretation of existing signal parameters by measuring and utilizing the time duration between signal transitions. Instead of treating transition intervals as fixed or irrelevant, the invention extracts additional data by analyzing variations in these time parameters, thereby increasing throughput without changing the fundamental protocol structure
2Productivity
If signal frequency is increased to improve throughput, then data transmission rate increases, but robustness against distortions decreases
Solution Approach 1:
Instead of increasing signal frequency to improve throughput, the patent extracts additional data from the temporal dimension of existing transitions. By measuring time intervals between transitions that already occur at robust frequencies, the system increases effective data rate without compromising signal robustness or requiring higher frequency operations
3Productivity
If additional data channels are added to increase bandwidth, then throughput is improved, but device complexity and cost increase
Solution Approach 1:
The patent makes the existing signal transitions serve multiple functions: the primary data transmission role remains intact while the same transitions simultaneously carry additional data through temporal interval encoding. This multi-functionality increases effective bandwidth without requiring additional physical channels or devices
Solution Approach 2:
The patent combines primary data transmission and additional data transmission into a single signal protocol. By merging these functions into one unified approach where time intervals between transitions carry supplementary information, the system achieves higher throughput without the complexity of multiple separate data channels

AI summary
A receiver includes a receiver circuit to receive a first transition in a first direction, a second transition in a second, different direction after the first transition and a third transition in the first transition after the second transition of a signal. A first time period between the first and third transitions is indicative of a datum to be received. The receiver circuit is also configured to determine a second time period between the first transition and a second transition and to determine an additional datum to be received based at least on the determined second time period between the first and second transitions. Using the determined second time period allows for more information to be received in a reliable manner.
