Abstract
A remote monitor unit comprising a battery pack, a regulated power supply, program control board, a receiver AD board, a plurality of memory boards and a transducer, all housed in a water tight enclosure. External control or data communication links are unnecessary with the remote monitor unit. Once the device has been activated and placed in its housing, a programmable time delay feature allows the user to place the unit at a selected site in advance of the start of the recording period without wasting any data storage capability. When deployed and activated, analog data from the transducer is converted to digital form and silently recorded by storing it in a non-volatile memory medium on the memory boards. The digitized information is later retrieved from the memory boards by micro, mini or main frame computer and stored on magnetic tape for subsequent processing. The memory boards are then erased by exposure to ultra-violet light and reused.
