Project – “Stereo Audio Compressor” Starting speech Audio compressors that use a light source to control a Light Dependent Resistor (LDR) are not new‚ and indeed there are many classic optical compressor designs. The design goal of the SOC-1.1 was to further enhance the attributes of optical compression to provide the user with alot more functionality as well as improve the compressor response to real world audio signals. We have carefully examined the characteristics of the LDR and developed

Introduction Microscopes have brought to light a new realm of information that originally laid dormant and invisible to the naked eye. It has enhanced biology and brought forth great advancements into the study of living organisms. Many discoveries have been achieved through the microscope. One of the major ones is the cell theory that we have talked about in this chapter. Having a microscope enables us to study even the smallest of details in organisms and allows us to conduct research. Another

Business Challenge #6: To develop the best scratch resistant coating in the world for ophthalmic lenses [Titan] Background The ophthalmic lenses (spectacle lenses) consist of some base material (substrate) like CR 39‚ Polycarbonate‚ Trivex and a surface treatment is given to them to increase their hardness. Currently‚ there are 2 processes of applying this coating‚ i.e. Dip coating and Spin coating. The current scratch resistant (Hard) coating on plastic and polycarbonate lenses available in the

Investigation into how the focal length of a lens affects the temperature at the focal point Research & Rationale: In my project I will be looking in to how different lenses with varying thicknesses and therefore focal points magnify and intensify light passing through it. To do this I will be measuring the temperature of an object behind the lens‚ at the focal point. The study and research of lenses was not part of the course this year‚ so I thought it would be more interesting to study a new

Light Microscopy Lab Lab write-up 1 Parveen Rajper Biology 101 Principles of Biology 1 September 29‚ 2012 Introduction: The light microscope helps see the microscopic world that the naked eye cannot see. If there were no microscopes in the world‚ than it would be very difficult to understand the many particles that surround the living world. The purpose of this lab experiment is to become familiar with a microscope. It is hypothesized that it will be difficult

Laboratory Exercise #2 Pre Lab This lab will teach me how to use a spectrophotometer. The use of the spectrophotometer is to measure the concentration of solute. The solute being measured must be colored and is determined based on the adsorption of light photons on a wavelength. The spectrophotometer uses a beam of light that strikes the diffraction grating that basically forms of prism of light. Then only a specific wavelength of light shines through the spectrophotometer and interacts with
