20120091942, Apr 19, 2012

Filed:

Jan 11, 2011

Appl. No.:

13/004857

Inventors:

Jack A. Jones - Los Angeles CA, US
Yi Chao - Pasadena CA, US
Thomas Curtin - Arlington VA, US

International Classification:

H01M 10/46

US Classification:

320101

Abstract:

A submerged charging station having a rechargeable energy producing device is disclosed. The device comprises a submerged thermally based electric generator that comprises a temperature-responsive material that utilizes differences in depths in order to generate energy. The submerged thermally based electric generator changes depths along a tether that is attached to a buoy and an anchor. The submerged thermally based electric generator provides energy to a battery, which can be part of the charging station, or to an autonomous underwater vehicle (AUV) that travels to different charging stations to be recharged.

Abstract:

An electromagnetic shearflowmeter for remote oceanic applications is disclosed, wherein a pair of housings, each having disposed therein an electric coil, are spaced to define an open cylinder through which a fluid in which the shearflowmeter is immersed may flow relatively free of obstructions. Electrodes are embedded symmetrically in the surfaces of the housings for sensing electromagnetic signals deriving from activation of the coils and which signals are modified as a function of the rate and direction of flow through the open cylinder of the fluid in which the apparatus is immersed. A plurality of such apparatus may be operated at different depths along a common mooring to measure differentials of flow, also called shear, within the fluid system. An electronic amplification circuit having an excellent common mode-rejection ratio and common mode range, used in conjunction with the other apparatus, is also disclosed.
