Wireless Device Anti-Phase Signal for Call Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public use of wireless devices for verbal conversations can be considered rude, distracting, or intrusive, leading to noise pollution and privacy concerns, as conversations may be overheard by bystanders in public settings.
Innovation Solution
A wireless device system that processes voice communications to generate a response signal, which is broadcast to interfere with the original voice signal, making it less discernible to bystanders through destructive interference or distortion, thereby enhancing privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If voice communication is broadcast publicly, then communication clarity is improved, but privacy is compromised and noise pollution increases
Solution Approach 1:
The patent applies destructive interference to convert the harmful effect of audible voice signals into a benefit by canceling them out in public spaces. The system generates an anti-phase signal that destructively interferes with the original voice signal, making the conversation inaudible to bystanders while maintaining communication functionality between the intended parties.
Solution Approach 2:
The system preemptively generates and broadcasts a counter-signal before the original voice signal can be fully heard by bystanders. By introducing the anti-phase signal in advance and maintaining it throughout the conversation, the system prevents the harmful effect of public audio transmission rather than attempting to mitigate it after the fact.
2Object-affected harmful factors
If a response signal is broadcast to cancel voice signal, then privacy is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical acoustic isolation systems with an electronic signal processing approach. Instead of using physical barriers or complex acoustic engineering to prevent voice transmission, the system uses digital signal processing to generate and broadcast an electronic anti-phase signal that cancels the original voice signal through destructive interference.
3Object-affected harmful factors
If voice signal is processed and response signal is generated, then privacy is enhanced, but energy consumption increases
Solution Approach 1:
The system creates a copy of the original voice signal, processes it to generate an anti-phase version, and broadcasts this copied signal. By working with a digital copy rather than manipulating the original acoustic wave directly, the system can efficiently process and invert the signal using computational methods that consume less energy than physical acoustic manipulation would require.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively reduces the audibility of voice communications to bystanders, providing users with greater privacy and reducing noise pollution in public environments, allowing for more comfortable and secure verbal exchanges.
Implementation Method 1
The response signal may be broadcast about the periphery of the user as the voice input is received for reducing the voice communication discernible by one or more bystanders
Data Source
AI summary
A system and method for providing call privacy for a wireless communication device. A voice communication is received from a user. The voice communication is processed to determine a response signal in response to receiving the voice signal. The response signal is broadcast about the periphery of the user as the voice input is received. The response signal is operative to cause the voice communication to be less discernible by one or more bystanders.
