ELECTRIC CIRCUIT ASSEMBLY APPARATUS

摘要

A sensor buoy, such as a sonobuoy, is described as one example of apparatus comprising an electrical circuit assembly having a housing surrounding the assembly, the housing comprising a thermoplastic shell blow-moulded around the circuit assembly. The described sensor buoy has a terminal weight and a sensor for deployment beneath the surface of the water after the buoy impacts the water with a cable connecting the sensor to the circuit assembly. The circuit assembly is arranged to process the output of the sensor. An antenna is arranged to transmit a signal corresponding to the output.
