Show moreThe use of digital circuits in incre asingly diverse applications and environments has greatly increased the probability of electromagnetic interference in digital machines. The source and control of noise in digital systems have become major considerations in hardware design. This paper addresses these problems and their solutions. The noise immunities of various semiconductor families are compared showing design tradeoffs. The effects of transmission line reflections on digital wave forms are analyzed. The means for calculating interference between conductors (crosstalk) are shown with appropriate approximations. The effects of shielding conductors and circuitry are explored with formulas for near field calculations shown. Proper grounding and power supply decoupling methods are shown to be paramount to proper system design. The paper ends with an approximate noise analysis of a simple computing machine.

The World Health Organization has identified the need for affordable, specific, rapid and deliverable point of care assays for infectious diseases in areas that are resource poor and lacking readily available complex testing methods. The objective of this research is to discover improved methods of capturing and counting CD4+T, in a portable assay to aid in the detection of HIV or other diseases that are informed by cell identification and count. The research divides into 4 major objectives:...
Show moreThe World Health Organization has identified the need for affordable, specific, rapid and deliverable point of care assays for infectious diseases in areas that are resource poor and lacking readily available complex testing methods. The objective of this research is to discover improved methods of capturing and counting CD4+T, in a portable assay to aid in the detection of HIV or other diseases that are informed by cell identification and count. The research divides into 4 major objectives: Design an improved portable, microchip. to isolate cells in a timely manner. Explore, design and prove the optical technology that provides large field-of-view and enables imaging large surface area simultaneously so that a sufficient sample can be collected. Test and analyze the microchip and optics to verify the specificity and efficiency of the biological process. Identify and count the cells in an automated manner.
