US Patent:

6563802, May 13, 2003

Filed:

Jun 22, 1998

Appl. No.:

09/102098

Inventors:

Roger D. Hayward - Beaverton OR

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H04B 320

US Classification:

370286, 370287, 37940601, 455570

Abstract:

An echo cancellation system measures an average delivery rate of a reference data signal and an average capture rate of an input data signal. From the measured data rates, the system converts the reference data signal to a domain of the input data signal. An echo canceler cancels an echo that may be present in the input data signal based upon the converted reference data signal.

Assignee:

3SI Security Systems, Inc. - Exton PA

International Classification:

G08B 13/14

US Classification:

34053913, 3405681, 3405687, 340571, 34082549, 109 2, 109 15

Abstract:

A flexible security device for tracking and location. The device comprises a flexible housing having a hollow medial region. A location tracking assembly is contained, at least in part, within the hollow region. The location tracking assembly comprises a plurality of modules, including a wireless communications antenna module, a wireless communications electronics module, a global positioning system antenna module, a global positioning system electronics module, and a power module. A plurality of interconnects are configured among the plurality of modules, with one or more of the interconnects having sufficient flexibility to permit relative movement of at least one module relative to an adjacent interconnected module.

Appl. No.:

12/287213

Inventors:

Kenneth R. Smith - Portland OR, US
Roger Hayward - Beaverton OR, US

Assignee:

Cascade Microtech, Inc. - Beaverton OR

International Classification:

G01R 31/00

US Classification:

324754, 3241581

Abstract:

In a membrane probing apparatus, the impedance of the interface between coaxial cables connected to the test instrumentation and the membrane supported co-planar waveguide that conductively connects to the probe's contacts is optimized by eliminating a ground plane in the interface board.

Appl. No.:

12/121745

Inventors:

Timothy Pfafman - Truckee CA, US
Roger Hayward - Long Beach CA, US
Richard Fuller - Gilroy CA, US

Assignee:

3SI Security Systems, Inc. - Exton PA

International Classification:

G08B 1/08

US Classification:

34053913, 3405391, 3405731, 3405721, 342463

Abstract:

In one embodiment, a method is provided for selectively providing an alert to a user of a tracked asset in an asset recovery system. The method includes activating a tracking device on the tracked asset to generate a report, evaluating the report and a condition based on a home location assigned to the tracking device for generating an alert, creating the alert based on the evaluation of the condition and the report, and sending the alert to the user.

Filed:

Jun 10, 2009

Appl. No.:

12/456118

Inventors:

Eric W. Strid - Portland OR, US
Kenneth R. Smith - Portland OR, US
Roger Hayward - Beaverton OR, US

International Classification:

G01R 35/00

US Classification:

324601

Abstract:

The tolerance of Short-Open-Load (SOL) and Short-Open-Load-Reflect (SOLR) VNA calibration for variability in probe position is improved by using load and short calibration structures having impedance elements with a length at least two times the probe contact pitch and a width at least two times the sum of the combined pitches of the probe contacts.

Appl. No.:

12/354253

Inventors:

Joel Bartholf - Macon GA, US
Roger Hayward - Long Beach CA, US
Richard Fuller - Gilroy CA, US

International Classification:

G08B 13/14

US Classification:

3405727, 3405721

Abstract:

A tracking system and method provide updated location and status information of a vending machine even after the vending machine is moved from its installed location. This allows law enforcement to use the updated location information to locate and recover the vending machine and the assets contained therein during a theft or in other security breach situations. A method also provides for automatically assigning the vending machine to an installation location using the location and status information from the vending machine.

Filed:

Appl. No.:

17/143850

Inventors:

- Livermore CA, US
Roger Hayward - Beaverton OR, US
Roy Swart - Hillsboro OR, US

International Classification:

H04B 17/12
H04B 17/16
H04B 17/19

Abstract:

Improved electrical testing of N-port beamforming devices is provided. For testing, an N:1 electrical network is connected to the N ports of the device under test to provide a single test port. This mode of testing can be used to determine parameters of interest (e.g., far field radiation patterns etc.) of the device under test more rapidly than with antenna range testing or with characterization of each port of the device under test. The N:1 electrical network can be passive or active. The N:1 electrical network can be integrated in a probe head to provide probe array testing of beamforming devices. Alternatively, the N:1 electrical network can be integrated with the device under test to provide onboard testing capability.
