Shared Digital Interface for Multi-Receiver Data Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As communication devices integrate multiple types of application data, the complexity of interfaces between components increases, leading to inefficiencies and higher costs, particularly due to the challenges of mitigating multi-path effects such as jitter and ghosting in wireless communication systems.
Innovation Solution
A circuit with first and second receiver circuitry, a frame buffer, and a common digital interface that selectively receives and manages different types of application data, using a control signal to facilitate efficient integration and presentation to a digital baseband processor, potentially sharing circuit elements and forming the radio frequency circuit in a single integrated circuit to reduce complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of application data are integrated into a single communication device, then the device becomes more convenient and functional, but the complexity of interfaces between components increases
Solution Approach 1:
The patent implements a universal digital interface that can handle multiple types of application data (cellular, GPS, etc.) through a single standardized connection. The frame buffer and control logic provide multi-functional capability, allowing the same interface to process different data types by selectively receiving and buffering appropriate data streams based on control signals, thereby eliminating the need for separate dedicated interfaces for each application type.
2Productivity
If multiple receiver circuitry are used to handle different application data, then data handling capability improves, but circuit complexity and cost increase
Solution Approach 1:
The patent combines multiple receiver circuitry (first receiver for cellular data, second receiver for GPS data) into a unified architecture that shares common components. The frame buffer serves as a common resource that receives data from multiple receivers, and the single digital interface consolidates multiple potential connections into one, reducing overall circuit complexity while maintaining the ability to handle multiple data types simultaneously.
3Reliability
If separate interfaces are used for different application data, then signal quality is maintained, but device cost and complexity increase
Solution Approach 1:
The frame buffer acts as an intermediary component between the multiple receivers and the single digital interface. It buffers and manages data from different sources (cellular, GPS) before presentation to the processor, ensuring that signal integrity is maintained while allowing consolidation of interfaces. The control signal mechanism provides selective routing that preserves signal quality requirements for different application data types.

AI summary
In one embodiment, a circuit can selectively adjust a current for driving a load. The circuit includes a sensor configured to measure a magnetic field associated with the current and provide a sensor voltage representative thereof. A control circuit is configured to selectively adjust the current as a function of the sensor voltage and a time-varying voltage threshold. Other methods and systems are also disclosed.
