Underwater cable arrangements and devices

This invention describes an underwater cable designed to be towed, with various external devices attached to its outside. These devices are powered wirelessly by magnetic coils, where one coil is inside the cable and another is in the external device, transferring energy without direct contact. The claims specifically narrow this to devices that also include a backup battery and a switch, and can incorporate sensors like a magnetic heading sensor or an acoustic ranging device.

Why it matters: Filed before significant advancements in efficient underwater inductive power transfer and miniaturized, low-power sensors. Modern electronics and materials could make these integrated, wirelessly powered seismic streamers more practical and efficient.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedUnderwater housing, inductive power, specialized sensors, electronics.
