Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In neonatal intensive care units (NICUs), high noise levels can lead to adverse health effects in infants, such as hearing loss and stress, and hinder bonding opportunities between infants and their caregivers, while existing noise reduction technologies are inadequate for NICU environments and do not effectively interpret infant cries for communication and medical diagnosis.
Innovation Solution
An electronic enclosure for incubators incorporating active noise control using adaptive noise cancellation algorithms and a sound analyzer to reduce noise and identify characteristics of infant voice signals, enabling effective noise reduction and communication, and potentially diagnosing medical conditions through voice analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If active noise control is implemented in incubators, then noise levels are reduced, but device complexity increases
Solution Approach 1:
The noise control system is segmented into distinct functional modules: reference microphones for noise detection, adaptive filters for signal processing, and secondary acoustic sources for noise cancellation. This modular segmentation allows the complex noise control function to be implemented through coordinated simple components, reducing overall system complexity while maintaining effectiveness.
Solution Approach 2:
The patent introduces intermediary elements such as reference microphones that detect noise before it reaches the infant, and secondary acoustic sources that generate anti-noise signals. These intermediaries act as mediators between the harmful noise and the infant, enabling noise reduction without requiring direct intervention or complex processing at the point of exposure.
2Adaptability or versatility
If communication systems are integrated into incubators, then bonding opportunities increase, but device complexity increases
Solution Approach 1:
The incubator system is designed with multi-functionality, integrating noise control, communication, and monitoring capabilities into a single platform. The same microphones and speakers used for noise control also serve communication functions, allowing parents to talk to and listen to their infants. This universality enables enhanced bonding opportunities without proportionally increasing device complexity.
Solution Approach 2:
The patent merges the noise control system and communication system into an integrated architecture. The reference microphones detect both noise and speech signals, and the secondary acoustic sources reproduce both anti-noise and parental voices. This merging allows the system to perform multiple functions using shared components, reducing overall complexity while providing both noise reduction and communication capabilities.
3Adaptability or versatility
If sound analysis is implemented to interpret infant cries, then diagnostic capability improves, but measurement precision requirements increase
Solution Approach 1:
The system performs preliminary action by detecting and analyzing sound signals continuously before medical intervention is needed. The adaptive filters continuously process acoustic signals to identify patterns in infant cries, breathing, and other vocalizations. This preliminary analysis enables early detection of potential medical issues such as respiratory problems or distress, improving diagnostic capability while using standard precision requirements through continuous monitoring.

AI summary
Systems, apparatuses and methods for integrating adaptive noise cancellation (ANC) with communication features in an enclosure, such as an incubator, bed, and the like. Utilizing one or more error and reference microphones, a controller for a noise cancellation portion reduces noise within a quiet area of the enclosure. Voice communications are provided to allow external voice signals to be transmitted to the enclosure with minimized interference with noise processing. Vocal communications from within the enclosure may be processed to determine certain characteristics/features of the vocal communications. Using these characteristics, certain emotive and/or physiological states may be identified.
