The increasing popularity of cellular phones with integrated cameras in the
recent past has led to major improvements in its image quality. However, integration of new features, such as mobile email, video streaming, MP3 etc. tend to put the limitation on image quality as camera phone designers struggle to manage...
Samples of insulating materials used in the construction
of electrical machinery and apparatus are
tested for dielectric strength before such are accepted
for use. This is done by applying to the sample a
high voltage until it is pierced through by the electric
spark. This is a parallel case to...
Electromagnetic engines, or motors, are machines in which the motive power is derived from electric currents by means of their electromagnetic action. The following design is for a 1½ K.W. bi-polar motor.
In an effort to fill an existing need two small electric service
vehicles were designed, constructed, and tested. The first
acted as a feasibility study and the second as a design prototype.
The vehicles had low cost and the capability of being fabricated by
their users as two main design...
A novel switched-R-MOSFET-C input branch is proposed for low-voltage and high-linearity applications. The tunability is achieved by varying the clock duty cycle using an automatic tuning circuit. This tuning method does not involve a change in gate voltage, and is therefore particularly suitable for low-voltage applications. The advantages of the...
Industry today is pushing personal portable handheld communication de- vices, from cellular telephones to personal navigation systems, and society is embracing the push. The goal is to make compact multi-functional handheld products that can transfer information to those around us through high bandwidth mobile communications. These modules rely heavily on...
This thesis presents new, compact configurations for RF/microwave bandstop and lowpass filters for embedded passive applications. A simple design methodology is presented for designing the folded-transmission line filters on a microstrip platform. Unlike the conventional stub-loaded filter designs, the proposed folded-line filters will have practical dimensions for a wide range...
The Department of Nuclear Engineering and Radiation Health Physics (NE/RHP) at Oregon State University (OSU) has been developing an innovative modular reactor plant concept since being initiated with a Department of Energy (DoE) grant in 1999.
This concept, the Multi-Application Small Light Water Reactor (MASLWR), is an integral pressurized water...
