US Patent:

7636016, Dec 22, 2009

Filed:

Sep 17, 2007

Appl. No.:

11/856677

Inventors:

Howard T. Russell - Fort Worth TX, US
Ronald L. Carter - Arlington TX, US
Wendell A. Davis - Arlington TX, US

Assignee:

Board of Regents, The University of Texas System - Austin TX

International Classification:

H03F 3/04

US Classification:

330288, 323315

Abstract:

An all-NPN bipolar junction current mirror circuit for mirroring an input reference current is disclosed. The circuit includes an input stage for providing an input reference current to the current mirror circuit, a reference stage for mirroring the input reference current and an output stage electrically connected to the reference stage for providing the mirrored input current to at least one load.

Appl. No.:

12/867801

International Classification:

G01B 7/16

US Classification:

702 34

Abstract:

An apparatus and method is provided for monitoring a condition of a structure using a passive wireless antenna sensor having a known resonant frequency when mounted on the structure. A series of radio frequency signals are transmitted with sweeping frequencies around the known resonant frequency to the passive wireless antenna sensor. The passive wireless antenna sensor includes a dielectric substrate disposed between an antenna pattern and a ground plane such that a change in the condition of the structure will cause a change in one or more characteristics of the passive wireless sensor. A signal is received from the passive wireless antenna sensor and a resonant frequency of the passive wireless antenna sensor is determined based on the received signal. The determined resonant frequency is then compared to the known resonant frequency, whereby a change in the resonant frequency indicates a change in the condition of the structure.
