Increased Image Resolution And Film Efficiency Via Vacuum Platens And Other Mechanical Devices, James A. Ruffing Apr 1980

Increased Image Resolution And Film Efficiency Via Vacuum Platens And Other Mechanical Devices, James A. Ruffing

Theses

With an appropriate lens, focusing arrangement, film and processing, motor driven 35mm cameras will attain resolutions of hundreds of line pairs per millimeter. The combination of a narrow depth of focus, unusually thin films, a relatively large film gate and rapidly advancing films can produce imagery with less than optimum resolution across or within individual frames. A vacuum platen and an additional styrene pressure plate were fitted to a motorized 35mm camera in an effort to insure the film lies flat. Continuous vacuum pulling mechanisms, suction and induction, were evaluated. Each system's simplicity, portability and statistically analyzed imagery were assessed. …

A Microprocessor Based Control System For An Electric Vehicle, Ronald C. Moffatt Mar 1980

A Microprocessor Based Control System For An Electric Vehicle, Ronald C. Moffatt

Theses

The control system described in this thesis is a low cost system designed to control the speed of an electric vehicle by adjusting the speed of a compound wound DC motor. The speed control method developed in this system is a combination of battery tapping, for control of the armature voltage, and pulse width modulation for field control; both generated by a microprocessor. Using a microprocessor, the control system is readily adaptable to a variety of motor voltages and motor control techniques by modifying the internal firmware of the processor. Overcurrent protection is included to prolong battery and motor life. …

The Measurement Of Rms Granularity Of Black And White Photographic Materials Using A Visual Comparison Technique, Jack C. Smith Jan 1980

The Measurement Of Rms Granularity Of Black And White Photographic Materials Using A Visual Comparison Technique, Jack C. Smith

Theses

A method is described for measuring the RMS granularity of black and white photographic materials at a diffuse density of 1.0 using a visual comparison technique. A set of standard granularity patches was prepared for use with a comparison microscope. Samples with known values of RMS granularity were evaluated by observers and it was found that the observer -measured values of granularity correlated well with the actual values of granularity. Some discrepancies from the expected relationship between observer-measured values and actual values are discussed.
