May 23, 2003
Appl. No.:
10/446284
Inventors:
David W. Fogliatti - Carlsbad CA, US
Brian K. Meadows - San Diego CA, US
Joseph D. Neff - San Diego CA, US
Visarath In - Chula Vista CA, US
Adi R. Bulsara - San Diego CA, US
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01P009/04
US Classification:
7350412, 7350414
Abstract:
An array of non-identical oscillators, driven by a common external driving force, is synchronized in phase. An example application is the phase synchronizing of non-identical vibratory gyroscopes to provide enhanced gyroscope sensitivity while minimizing the need for gyroscope proof mass alteration and individual gyroscope electronics.

Method Of Estimating Target Signals By A Dynamical Fluxgate Sensor

View page
US Patent:
7009392, Mar 7, 2006
Filed:
Jun 19, 2002
Appl. No.:
10/482999
Inventors:
John W. C. Robinson - Stockholm, SE
Mattias F. Karlsson - Bandhagen, SE
Peter Sigray - Skärholmen, SE
Adi R. Bulsara - San Diego CA, US
Luca Gammaitoni - Perugia, IT
Assignee:
Totalforsvarets Forskningsinstitut - Stockholm
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01R 33/04
US Classification:
324253
Abstract:
A method of estimating target signals (dc or low frequency signals) by a dynamical fluxgate sensor and a low-power fluxgate magnetometer operating according to the method. The sensor is pre-biased with a periodic bias signal in the form of a superposition of a square wave and a triangular wave. The change in residence time statistics in the stable state of the sensor is analyzed for estimating the target signals.

Coupled Nonlinear Sensor System

View page
US Patent:
7420366, Sep 2, 2008
Filed:
Jun 18, 2004
Appl. No.:
10/874009
Inventors:
Visarath In - Chula Vista CA, US
Antonio Palacios - San Diego CA, US
Yong Kho - San Diego CA, US
Adi R. Bulsara - San Diego CA, US
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01R 33/04
US Classification:
324253, 324244
Abstract:
A sensor system employing a plurality of nonlinear sensors utilizes a coupling network to interconnect the sensors wherein the coupling network inherently induces oscillations in the sensor system. This approach removes the need to provide bias signal generation either onboard the sensors or via a source external to the sensor.

Coupled Nonlinear Sensor System For Sensing A Time-Dependent Target Signal And Method Of Assembling The System

View page
US Patent:
7528606, May 5, 2009
Filed:
Apr 4, 2007
Appl. No.:
11/732678
Inventors:
Visarath In - Chula Vista CA, US
Antonio Palacios - San Diego CA, US
Yong Ko - San Diego CA, US
Adi R. Bulsara - San Diego CA, US
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01B 3/08
G01R 33/04
US Classification:
324326, 32420716, 324253
Abstract:
A coupled non-linear sensor system is provided for sensing a non-sinusoidal time-dependent target signal. The system comprises an odd number, other than one, of interconnected oscillatory sensors for sensing time-dependent changes in an external magnetic flux generated by the non-sinusoidal time-dependent target signal, the sensors coupled to each other by a coupling parameter characterized by a threshold value, so that each of the sensors oscillates in the presence of the non-sinusoidal time-dependent target signal as the coupling parameter exceeds the threshold value.

Wideband Nonlinear “Channelizer” For Rapid Processing Of Static And Time-Varying Signals

View page
US Patent:
7714671, May 11, 2010
Filed:
May 30, 2007
Appl. No.:
11/755601
Inventors:
Visarath In - Chula Vista CA, US
Joseph D. Neff - San Diego CA, US
Adi R. Bulsara - San Diego CA, US
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
H03B 27/00
US Classification:
331 57, 331 46, 324326, 324253, 32420716, 702150, 702151, 702152, 702153, 342133, 342129
Abstract:
A target signal analyzer having at least one receiving antenna configured to receive the target signal, and a parallel array of oscillator rings. Each oscillator ring is operatively coupled to receive the target signal from the receiving antenna. Each oscillator ring has an odd number of at least three bistable, nonlinear oscillators circularly coupled to each other such that only one-way signal flow is allowed between the oscillators in each oscillator ring. Each of the oscillator rings is configured to oscillate and thereby produce a response signal only when the target signal frequency is within a designated frequency band. For every designated frequency band in a spectrum of interest, at least one of the oscillator rings is configured to produce a response signal.
