Motivation for In Vivo Optical Imaging (Partial List)
• Safety — Non-ionizing radiation: photon energy is ~2 eV
• Physics — Molecular structure and composition of tissue
• Optics — High intrinsic contrast. E.g., absorption probes
 Oxy-hemoglobin & deoxy-hemoglobin
 Melanin
 Lipid
 Water
 DNA & RNA
• Physiology — Endogenous contrast for functional imaging
 Concentration of hemoglobin (angiogenesis)
 Oxygen saturation of hemoglobin (hyper-metabolism)
 Cell nuclei
 ....etc

Abstract
AThe transimpedance limit describes the maximum transimpedance that a transimpedance amplifier (TIA) can attain for a given bandwidth and technology. We analyze and compare this limit for a wide variety of TIA topologies thus exposing their relative merits. The topologies considered are the shunt-feedback TIA with single and multistage amplifier, the shunt-feedback TIA with feedback capacitor, the shunt-feedback TIA followed by a post amplifier, the shunt-feedback TIA with a current amplifier, the common-base/gate feedforward ....etc

INTRODUCTION
We propose to design and build an automobile speed limit alarm which notifies the driver of excessive speeds linked to a speed limit sign by a wireless link.
This alarm will sound when the driver exceeds the speed limit by a specified amount.
PROJECT GOALS
One of our goals for this project are to successfully design a wir ....etc

STANDARD
A standard is an object, system, or experiment that bears a defined relationship to a unit of measurement of a physical quantity.
Standards are the fundamental reference for a system of weights and measures, against which all other measuring devices are compared
The ideal standard is independently reproducible without uncertainty
Any system of measurement must be related to a known standard otherwise the measurement has no meaning
BASIC CLASSIFICATION OF STANDARDS
PRIMARY STANDARDS:
It is prepared under the most ....etc

APPLICATION OF SEMICONDUCTOR STRAIN GAUGES IN MEASUREMENTS OF DYNAMIC STABILITY DERIVATIVE
Abstract
Low amplitude of signals in measurements ofstability derivatives is a known problem.Solution by applying semiconductor straingauges is presented. Foil strain gauge balancewas replaced with a semiconductor fivecomponentstrain gauge balance, andsemiconductor excitation moment sensor wasapplied. Wind tunnel test data are presented
