Cable Modem Trap Detection Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable trap audits are manual, expensive, and ineffective, particularly in multi-dwelling unit buildings where advanced notice can allow for re-installation or replacement of cable traps before inspection, making them vulnerable to unauthorized service access.
Innovation Solution
Implementing a computer-implemented method in cable modems for automatic detection of cable traps by creating a trap-detection object to determine the presence or absence of a properly functioning cable trap through monitoring video signals at specific frequencies, using a trap-detection module that reports findings via network protocols to reduce the need for manual inspections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inspection is used for cable trap audits, then inspection can be performed, but the process is expensive and time-consuming
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated electronic detection system. The cable modem automatically detects the presence or absence of cable traps by analyzing video signals, eliminating the need for manual physical inspection. This substitution dramatically improves audit efficiency while reducing time consumption.
Solution Approach 2:
The cable modem performs self-diagnosis by automatically detecting whether cable traps are properly installed. The system uses its own video signal processing capabilities to identify trap presence without external intervention, enabling the network to self-monitor and self-report trap status.
2Ease of operation
If advanced notice is given before inspection, then access to utility closets can be obtained, but cable traps can be re-installed or replaced before inspection
Solution Approach 1:
The system performs preliminary detection continuously or on-demand without requiring advance scheduling. The cable modem is already in place and can immediately detect trap status when triggered, eliminating the window of opportunity for trap removal or replacement that exists during manual inspection scheduling.
Solution Approach 2:
The system provides immediate feedback on cable trap status to the cable company. When a trap is detected as absent or malfunctioning, the system automatically reports this, enabling rapid response before unauthorized access can occur. This continuous feedback loop maintains detection accuracy without requiring advance notice to customers.
3Reliability
If cable traps are used to block unauthorized services, then service security is provided, but the traps are susceptible to alteration and removal
Solution Approach 1:
The patent replaces the passive mechanical cable trap with an active electronic detection system. Instead of relying solely on the physical presence of a trap, the system electronically monitors for the trap's presence by analyzing video signal characteristics. This substitution transforms security from a static physical barrier to a dynamic monitored system that can detect and report tampering attempts.
Solution Approach 2:
The detection system acts as an intermediary between the cable trap and the cable company. It continuously monitors the trap's presence and communicates its status, providing an additional layer of security that alerts the cable company to any attempted alterations or removals of the trap mechanism.
Data Source
AI summary
Firmware is installed in a cable modem, enabling detection of the presence or absence of a cable trap in the feed of a customer location. Such a cable modem includes a trap-detection module and a trap-detection object. The trap-detection module is configured to determine whether a signal is present at a cable-television frequency. The trap-detection object is configured to store data as to whether the signal is present and support polling by providing the stored data in response to a received polling command.
