Patent 7435148 was granted and assigned to Acr Electronics, Inc. on October, 2008 by the United States Patent and Trademark Office.
A hydrostatic release for securing an emergency position indicating radio beacon (EPIRB) to a shipboard surface to withstand high G-forces while having a release mechanism that if the ship were to sink will release the EPIRB at a pre-determined water pressure which is equivalent to depth of water. The hydrostatic release includes two shafts mounted end to end and clamped together under spring pressure by a slide that can be moved by a water pressure sensitive diaphragm when the hydrostatic device is underwater and experiences a pre-determined water pressure. The elongated shaft is connected at one end to an EPIRB housing and at the other end to the EPIRB housing cover. Once the cover is released by the water pressure, the EPIRB will float to the ocean surface.
