Uav Power Line Position And Load Parameter Estimation

View page
US Patent:
20120016538, Jan 19, 2012
Filed:
Jun 20, 2011
Appl. No.:
13/164611
Inventors:
James W. Waite - Los Gatos CA, US
Thorkell Gudmundsson - San Jose CA, US
Dimitar Gargov - Merced CA, US
International Classification:
G05D 1/10
G05D 1/00
US Classification:
701 3, 701300
Abstract:
A system and method for providing autonomous navigation for an Unmanned Air Vehicle (UAV) in the vicinity of power lines is presented. Autonomous navigation is achieved by measuring the magnitude and phase of the electromagnetic field at an unknown location within a space under excitation by a set of power cables of the power line with one or more orthogonal electromagnetic sensors formed on the UAV; modeling a set of expected complex electromagnetic strengths of the set of power cables at the currently estimated position and orientation of the UAV based on a model of the set of power cables; and estimating parameters related to a position and orientation of the UAV, and load parameters of each cable based on the residual error between the measured set of complex electromagnetic field values and the set of expected electromagnetic field values corresponding to a combined model of the set of power cables.

US Patent:
20120232800, Sep 13, 2012
Filed:
May 22, 2012
Appl. No.:
13/477909
Inventors:
JOHAN OVERBY - Milipitas CA, US
James W. Waite - Los Gatos CA, US

Assignee:
Metrotech Corporation Inc. - Santa Clara CA
International Classification:
G06F 17/40
G01V 3/12
G06F 19/00
US Classification:
702 7, 324332
Abstract:
A method for determining the location of an underground sonde transmitter is disclosed. In some embodiments, the method includes measuring a set of complex electromagnetic field magnitude and phase strengths at one or more of positions while traversing a target sonde path at any angle using one or more electromagnetic coil sensors, modeling a set of expected complex electromagnetic strengths of a hypothetical sonde at the one or more of positions for one or more of the electromagnetic coil sensors, the set of expected electromagnetic field values corresponding to a model for the target sonde, and estimating parameters related to the target sonde based on the residual error between the measured set of complex electromagnetic field values and the modeled set of expected complex electromagnetic field strengths, wherein a final estimated parameter set is determined after the residual error has converged to a minimum tolerance.

US Patent:
20220268961, Aug 25, 2022
Filed:
Feb 24, 2021
Appl. No.:
17/184324
Inventors:
- Merced CA, US
Dimitar Gargov - Merced CA, US
International Classification:
G01V 3/10
G01V 13/00
Abstract:
A metal detector detects when a target that is a desirable metal object is located within a medium. A signal is transmitted into the medium. A response signal is received from the medium. The response signal includes a secondary medium response signal from the medium and includes a secondary target response signal from the target when the target is located within the medium. The response signal is amplified to produce an amplified signal. Compensation circuitry perform transmit coil transfer function compensation on the amplified signal to produce a compensated signal. A notch module removes a resistive component of the secondary medium response signal from the compensated signal.

US Patent:
20190353818, Nov 21, 2019
Filed:
May 9, 2019
Appl. No.:
16/408459
Inventors:
- Merced CA, US
Dimitar Gargov - Merced CA, US
International Classification:
G01V 3/165
Abstract:
A metal detector detects when a target that is a desirable metal object is located within a medium. A signal is transmitted into the medium. A response signal is received from the medium. The response signal includes a secondary medium response signal from the medium and includes a secondary target response signal from the target when the target is located within the medium. The response signal is amplified to produce an amplified signal. Compensation circuitry perform transmit coil transfer function compensation on the amplified signal to produce a compensated signal. A notch module removes a resistive component of the secondary medium response signal from the compensated signal. A signal vector resistive component demodulator produces a vector resistive component output signal from output of the notch module. A vector reactive component demodulator produces a vector reactive component output signal from the output of the notch module. Output from the signal vector resistive component demodulator and the signal vector reactive component demodulator is digitized to produce digital signals. A digital signal processor processes the digital signals.

Filed:
Jun 7, 2017
Appl. No.:
15/616704
Inventors:

International Classification:
G01V 3/10
Abstract:
In accordance with aspects of the current invention, a method of determining a location of a utility line includes driving one or more transmitters with a continuous wave signal; either adjusting for effects of direct coupling between the transmitters and one or more sensors mounted on the same rigid platform or different platforms or maintaining sufficient separation between a transmitter platform and a sensor platform to minimize such effects; and deriving a position of the line relative to the sensors from the measurements.
