  "abstract": "This disclosure describes a system for real-time localization of hand tools within an industrial assembly environment. The system utilizes time difference of arrival (TDOA) principles from fixed reference tags to pinpoint the spatial coordinates of tool-mounted transponders. This arrangement addresses the problem of inadvertently using a specific tool at an incorrect assembly station, a common error that can lead to manufacturing defects which are often discovered only much later in the production process, incurring significant rework costs and production delays. The disclosed system provides continuous positional data to prevent such misapplications.",
