Systems in Action

---

We are developing a low-cost, event-driven acoustic sensing concept for persistent maritime awareness. Project Jellyfish combines distributed underwater sensor nodes, local signal processing, and surface-based data fusion to reduce the power and bandwidth demands of continuous acoustic monitoring. Rather than transmitting raw data, the system is designed to identify meaningful events at the edge and report only compressed, actionable information. The current effort focuses on validating detection feasibility, node-level processing, communications, and scalable deployment under realistic operational constraints.

We investigate complex product and service failures where technical symptoms, repair records, and organizational responsibilities are spread across multiple systems. This case study examines a connected-vehicle issue involving unreliable GPS, emergency communication, app connectivity, repeated service visits, and unresolved technical escalation. By organizing field evidence, repair documentation, technical references, and service communications, the project established a clear factual record and a structured path for regulatory review, warranty escalation, and accountable resolution.

We investigate real-world product failures where technical faults, prior repairs, limited component-level serviceability, and unclear warranty coverage make resolution difficult. This case study examines a residential appliance affected by repeated control-board and door-lock issues, inconsistent repair history, and limited access to individual replacement parts. By combining hands-on troubleshooting, evidence review, parts and cost analysis, and targeted corrective action, the project restored operation, documented the failure path, and developed practical recommendations concerning modular repairability, reliable fallback controls, and clearer long-term warranty coverage.
