Home Automation System, Joshua James Earl May 1998

Home Automation System, Joshua James Earl

Undergraduate Honors Capstone Projects

The home is the place where people should feel the most comfortable. Considerable technological development is dedicated to making the home more comfortable; smart appliances are a good example of this. There is always a market for products that provide easier control of home appliances and electrical devices. With this in mind, I have designed and implemented a PC-controlled Home Automation System (HAS). This HAS allows complete control of home appliances and electrical devices from the homeowner's IBM-compatible PC. make use of advanced technology in the transmission of the control signals by way of power-lines already present in the home. …


Optimization Of Torquer Coil Design For Use With The Small Satellite Attitude Control Simulator, David Deloyd Anderson May 1996

Optimization Of Torquer Coil Design For Use With The Small Satellite Attitude Control Simulator, David Deloyd Anderson

Undergraduate Honors Capstone Projects

This paper presents a procedure used to optimize the performance of a ferromagnetic core magnetic torquer coil design for use on the Space Dynamics Laboratory (Logan, UT) Small Satellite Attitude Control Simulator. The items of optimization include the primary goal of maximizing the coil 's magnetic moment while reducing power consumption and system mass within given power, mass, and dimensional constraints. The optimization process makes use of several simple equations to determine a few starting points for design, after which an iterative approach based on experimentation is used to produce the final design. It is found that optimal magnetic moment …
