Introduction

John R Dale is a notable inventor based in Pennsburg, PA (US), recognized for his contributions to underwater acoustic surveillance technology. With a total of 8 patents, Dale has made significant advancements in the field, particularly in systems designed for monitoring sound sources over large geographic areas.

Latest Patents

One of his latest patents is the Pressure Responsive Clasp, which details an underwater acoustic surveillance system. This system is designed to obtain data related to sound sources of interest in extensive geographic areas over prolonged periods. The system involves deploying acoustic sensors from an aircraft, which are then placed on the sea floor at predetermined locations. Each sensor is equipped with a parachute that slows its descent, ensuring a stable platform for hydrophones and acoustic projectors once it reaches the bottom. Additionally, a web-like flow shield is deployed to minimize hydrophone noise caused by water currents. The system also includes a water-activated battery that ensures the sensor remains upright and provides power for data transmission. Acoustic data is retrieved by a sonobuoy deployed on the surface, allowing for efficient monitoring of sound sources.

Another significant patent is the Sonobuoy Suspension System, which features a spring motor that maintains a constant output torque. This motor is housed within an upper sonobuoy unit and is connected to a lower sensor unit via a non-compliant suspension cable. This design isolates the sensor unit from wave effects, allowing it to operate effectively at a predetermined underwater depth.
