Engineering Contradiction Analysis
1Adaptability or versatility
If traditional methods are used to store and configure multiple acoustic signal profiles, then waveform configuration flexibility is maintained, but setup time increases and circuit complexity increases
Solution Approach 1:
The patent segments the acoustic signal profile configuration into discrete operable states, where each state is defined by a specific combination of first and second digital signals. This segmentation allows the system to pre-define and store multiple distinct signal profiles as separate operable states, enabling rapid switching between different waveform configurations without requiring complex real-time processing, thus reducing setup time while maintaining flexibility.
Solution Approach 2:
The patent implements preliminary action by pre-configuring and storing multiple operable states in memory before actual ultrasound imaging operations. Each operable state represents a pre-defined acoustic signal profile with specific characteristics. During operation, the system can directly recall and apply these pre-configured states without performing complex configuration routines, significantly reducing setup time while maintaining waveform configuration flexibility.
2Adaptability or versatility
If traditional methods are used to store and configure multiple acoustic signal profiles, then waveform configuration flexibility is maintained, but circuit complexity increases
Solution Approach 1:
The patent merges the configuration of multiple acoustic signal profiles into a unified state machine architecture. Instead of maintaining separate configuration circuits for each signal profile, the system uses a single state machine that transitions between pre-defined operable states. Each state is represented by a combination of first and second digital signals, allowing multiple waveform configurations to be managed through a single integrated circuit structure, thereby reducing overall circuit complexity while maintaining flexibility.
Solution Approach 2:
The patent implements universality by designing a multi-functional state machine that can generate and switch between multiple different acoustic signal profiles using the same hardware resources. The state machine can be configured to represent any number of operable states by programming the appropriate transition logic and signal combinations, eliminating the need for dedicated circuits for each waveform type and reducing overall device complexity.
3Measurement precision
If detailed waveform parameters are stored for each acoustic signal profile, then waveform accuracy is improved, but memory usage increases
Solution Approach 1:
The patent applies local quality by defining waveform characteristics through localized state transitions rather than storing complete waveform descriptions. Each operable state is defined by a specific combination of first and second digital signals at a particular point in the waveform cycle. This approach stores only the essential local characteristics (state combinations and transitions) rather than global waveform parameters, significantly reducing memory requirements while maintaining sufficient accuracy for ultrasound imaging applications.
Solution Approach 2:
The patent uses parameter changes to represent waveform variations through discrete state transitions. Instead of storing continuous waveform parameters that would require large memory, the system uses discrete digital signal combinations (first and second signals) to define different operable states. Each state transition represents a controlled parameter change in the acoustic signal, allowing accurate waveform configuration with minimal memory storage by encoding waveform characteristics in the sequence and combination of discrete states.

AI summary
A digital representation of a waveform is generated based on signals received during a recording period. The received signals include a digital clock signal providing a determined number of clock pulses during the recording period, a plurality of binary digital signals defining, for each clock pulse of the determined number of clock pulses, a waveform state associated with the clock pulse. A digital representation of the waveform is generated and stored. The waveform has a duration based on the recording period and a profile based on the defined waveform states associated with the clock pulses of the determined number of clock pulses.
