Remote Release Device for Marine Mammal Electronic Tags.

摘要

This new technology aims to provide researchers with a safe and reliable method for retrieving and reusing data-logging tags deployed on marine mammals. The RRD and handheld controller use the internationally-accepted Argos wireless-protocol for line-of-sight communication. Once interrogated with a unique command, the RRD activates its release mechanism s electrically- degradable epoxy. The RRD is separated from its baseplate within 10 seconds of being activated. Once retrieved, the RRD can be refurbished with a new cartridge and baseplate for subsequent deployment of payload devices. The tasks completed in this period focused on building and testing the RRD and its system components, which helped to identify assembly tasks and production costs associated with manufacture. Custom-built electronics have been integrated into the hardware of the RRD and the handheld controller. While their functionality has been verified, these devices contain embedded processors and their native applications continue to be written and tested. Mechanical housings and fixtures for assembling the RRD s release mechanism have been iteratively developed and tested for applicable bond strength and release time.
