20120182835, Jul 19, 2012

Filed:

Mar 19, 2012

Appl. No.:

13/423607

Inventors:

Robert Terry Davis - Satellite Beach FL, US
Armin Nyffenegger - Rockledge FL, US

Paul Thurston Richards - Melbourne FL, US

International Classification:

G01S 3/80

US Classification:

367118

Abstract:

Methods or systems for identifying seismic or acoustic signals of interest originating with moving motorized vehicles or footstep movement or stationary or moving machinery. A related system for monitoring an area includes a plurality of sensing devices each comprising a frame and a piezo-electric sensor element. A monitoring device is coupled to receive information from each of the sensing devices. One method includes providing a processing chain coupled to receive signal data from a sensor device which receives the signals, including a detection stage, a Joint Time Frequency (JTF) domain stage, and a classification stage. The detection stage identifies presence of signals that emerge from the background. The JTF domain stage estimates the state of the signals of interest over time. The classification stage assesses the previously derived information to form a decision about source identity. In one embodiment, the detector stage performs detections on a single cycle basis.

Appl. No.:

7/325694

Inventors:

Paul T. Richards - Melbourne FL
Robert L. Glassberg - Middle Island NY

Assignee:

Grumman Aerospace Corporation - Bethpage NY

International Classification:

G06F 15626

US Classification:

395129

Abstract:

A method and apparatus for processing and displaying data, and which are especially well suited to display high volumes of data at high rates, in a manner utilizing the vast human capability to perceive and recognize changes in patterns. The method comprises measuring values of a multitude of real life parameters a multitude of times, and forming a multitude of successive n-vectors from those values. Each n-vector has a plurality of components arranged in an order, and corresponding components of respective n-vectors are determined in the same manner from measured values of the real life parameters. Each n-vector is mapped onto an associated first k-vector; and each first k-vector has a plurality of components arranged in an order, and corresponding components of respective k-vectors are determined in the same manner from corresponding components of respective n-vectors. The method further comprises the steps of forming a multitude of successive images of a given type using data in the k-vectors, and displaying a multitude of the formed images.
