Florida Technological University College of Engineering Thesis; A special purpose modem has been designed to fill the interface requirements peculiar to RCA's DatawayTmk hotel/motel data management system. The modem interface operates on dedicated telephone quality wiring over distances up to 4000 feet using frequency shift keying. A data rate of 2880 bits per second is achieved through the interface. This report discussed the requirements of the interface and details the worst case design of...

The modem interface operates on dedicated telephone quality wiring over distances up to 4000 feet using frequency shift keying. A data rate of 2880 bits per second is achieved through the interface. This report discussed the requirements of the interface and details the worst case design of the modem transmitter and receiver sections. The approach used relies heavily upon the use of digital logic circuitry in the modulation and demodulation of the FSK signals.

University of Central Florida College of Engineering Thesis; There is a great need for a graphic simulation system used as a training device to take the place of actual flying. A good system will greatly reduce the cost of training men as well as cut down on casualties. Several systems have been tried and are now in use. Among them are two that are worthy of more study. These are the CCTV or model board and the digital systems. Both have several disadvantages that create a need for a new...
Show moreUniversity of Central Florida College of Engineering Thesis; There is a great need for a graphic simulation system used as a training device to take the place of actual flying. A good system will greatly reduce the cost of training men as well as cut down on casualties. Several systems have been tried and are now in use. Among them are two that are worthy of more study. These are the CCTV or model board and the digital systems. Both have several disadvantages that create a need for a new system. One such system is an optically based digitally processes system that combines the best features of two previous systems. This system uses charge-coupled-device memories that are digitally accessed by a microcomputer based system. The information from the CCD's is then processed and calculations are performed on it to transform it into a form that can be displayed on a cockpit-like screen. The system also allows for interaction between the pilot and itself.
