US Patent:

20110221416, Sep 15, 2011

Filed:

Mar 9, 2010

Appl. No.:

12/661005

Inventors:

Vadim V. Ivanov - Tucson AZ, US
Christian Link - Plano TX, US

International Classification:

G05F 1/70

US Classification:

323285

Abstract:

An energy harvesting system for transferring energy from an energy harvester () having an output impedance (Z) to a DC-DC converter () includes a maximum power point tracking (MPPT) circuit () including a replica impedance (Z) which is a multiple (N) of the output impedance. The MPPT circuit applies a voltage across the replica impedance that is equal to an output voltage (V) of the harvester to generate a feedback current (I) which is equal to an input current (I) received from the harvester, divided by the multiple (N), to provide maximum power point tracking between the harvester and the converter.

Appl. No.:

16/950227

Inventors:

- Dallas TX, US
Terry Lee Sculley - Lewisville TX, US
Christian Link - Plano TX, US

International Classification:

G01N 27/82

Abstract:

A method includes pulsating a magnetic field at a first location associated with an external surface of a wall containing magnetic material. The method also includes measuring at least one characteristic of the pulsating magnetic field at a second location associated with the external surface of the wall. The at least one characteristic changes based on corrosion on an internal surface the wall between the first and second locations. The magnetic field could be pulsated by applying an AC signal to a conductive coil or by vibrating a magnet. The method could also include analyzing the at least one measured characteristic to identify an amount of the corrosion and/or a change in the amount of the corrosion. Use of the internal surface the wall could be modified based on the amount or change of the corrosion.
